The 10 Most Terrifying Nazi Weapons Used on Real People -

At 6:43 PM on September 8, 1944, a 13-ton weapon fell from the edge of space and slammed into Staveley Road in Chiswick, London, at 3,500 mph—faster than sound, faster than any warning system ever built. The explosion carved a crater 30 feet deep. Three people died instantly: Ada Harrison, a 63-year-old woman; Rosemary Clark, a 3-year-old girl; and Bernard Browning, a soldier on leave. Nobody heard it coming. Nobody could have heard it coming. The weapon arrived before its own sound did. By the time the boom rolled across the neighborhood, the bodies were already in the rubble.

The British government told the public it was a gas main explosion. That was a lie. It was something far worse—something the world had never seen before. The age of the ballistic missile had begun, and the Nazis fired the first one. This is the story of 10 weapons. Not blueprints, not prototypes, not theoretical nightmares that stayed on the drawing board. These 10 weapons were built, deployed, and used on real human beings during the Second World War. Some killed thousands. One killed over a million. Some destroyed entire city blocks in a single strike. Others were so small they could fit in a child’s hand—and that is exactly who found them.

These are the 10 most terrifying Nazi weapons that were actually used on people. And every single one of them left scars that are still visible today.

Number one: the V2 rocket. The letter V stood for Vergeltungswaffe—vengeance weapon. And the Nazis meant every letter of it. The V2 was the world’s first long-range guided ballistic missile. It stood 47 feet tall, weighed nearly 29,000 pounds at launch, and its engine burned a mixture of liquid oxygen and ethanol, producing roughly 60,000 pounds of thrust. It climbed to an altitude of 55 miles, crossed the boundary of outer space itself, then tipped over and came screaming back down toward whatever city sat under its arc. By the time it reached its target, it was traveling at more than 3,500 mph—roughly five times the speed of sound.

The warhead carried about 1,600 pounds of high explosive—not as much as a large conventional bomb, but the speed made up for the size. The kinetic energy alone could flatten a building. Add the explosive to that, and you got craters deep enough to swallow a bus. The man behind it was Wernher von Braun, a young German engineer who dreamed of space travel as a teenager. He read books about rockets and the stars and imagined a future where humans left the planet. Then the Nazi military offered him funding. Von Braun took it. He would later claim he only wanted to build rockets for science. That may have been partly true, but the rocket he built was designed to kill civilians—and it did exactly that.

The development happened at Peenemünde, a secret research facility on the Baltic coast. Thousands of engineers worked there. The project consumed enormous amounts of German resources: fuel, materials, manpower. At one point, the V2 program was eating up a third of Germany’s entire fuel alcohol production. All of that for a weapon that could not be aimed with any real precision. The V2 could hit a city. It could not hit a specific building or military target. It was a terror weapon designed to break the spirit of civilian populations.

But the part of the V2 story that is not often told is not the people it killed when it landed. It is the people it killed during construction. The rockets were assembled in an underground factory complex called the Mittelwerk, carved into the Harz Mountains. The workers were concentration camp prisoners from a camp called Mittelbau-Dora. Conditions there were beyond description. Prisoners worked 12-hour shifts underground with almost no ventilation. They slept in tunnels on top of each other. Disease was everywhere: dysentery, typhus, starvation. Guards beat workers to death for moving too slowly. Conservative estimates say that at least 12,000 forced laborers died building V2 rockets. Some historians put the number closer to 20,000. Think about that. More people died making the V2 than were killed by it when it hit its targets. The weapon killed its builders more efficiently than it killed its enemies.

Beginning in September 1940, more than 3,000 V2s were launched against Allied targets. London took the worst of it. Over 1,000 rockets struck Britain. Another 1,600 or more hit targets on the European continent—primarily the city of Antwerp in Belgium. Antwerp became known as the city of sudden death. The rockets arrived without any warning at all. No air-raid siren could detect them. No fighter plane could intercept them. No anti-aircraft gun could shoot them down. You were walking down the street. You were eating dinner. You were putting your children to bed. And then the world ended. No sound. No shadow. Just a blinding flash and a wall of force that turned buildings into dust.

Estimates of total deaths from V2 strikes vary depending on the source. Some say around 5,500 killed and 6,500 seriously wounded. Others put the total casualties, including killed and injured, at approximately 9,000. The numbers are hard to pin down because records were incomplete, especially in Antwerp, where the destruction was immense and record-keeping suffered. About one in four V2s that were launched exploded in midair or crashed shortly after lift-off. The technology was cutting-edge, but unreliable. Some warheads were filled with nothing but concrete because Germany had run out of explosives. Others contained propaganda photographs of German civilians killed in Allied bombing raids.

The rockets were expensive, unreliable, and strategically almost useless. They did not slow the Allied advance by a single day. They did not destroy any military targets of importance. From a purely military standpoint, the V2 was a massive waste of German resources. But from a human standpoint, it was a nightmare. The people in London could not fight back against it. They could not see it. They could not hear it. They could only wait and hope that the next one would not land on them.

The British government initially tried to cover up the attacks entirely. They blamed the explosions on defective gas mains. The public was not fooled. People started calling the V2s “flying gas pipes”—with dark humor that barely covered the terror underneath. One strike stands above the rest in terms of sheer devastation. On the 25th of November, 1944, a V2 hit a Woolworth’s department store in New Cross Road, South London. It was a Saturday afternoon. The store was packed with shoppers. 168 people were killed. 121 were seriously injured. Entire families were wiped out in an instant. There was no warning. There was no siren. There was just a flash of light, and then a silence that lasted for years in the hearts of the survivors.

The V2 program ended when Allied forces captured the launch sites in the Netherlands in March 1945. The last V2 to hit London landed on the 27th of March. It killed 134 people. After the war, both the Americans and the Soviets raced to capture German rocket scientists and V2 hardware. Von Braun surrendered to the Americans and was brought to the United States under Operation Paperclip. He went on to lead the development of the Saturn V rocket that put Americans on the moon in 1969. Every modern ballistic missile in every nuclear arsenal on Earth traces its ancestry back to the V2. The weapon Hitler built to terrorize London became the foundation of the space age—and the slave laborers who died building it in the tunnels of Mittelbau-Dora never saw the sky those rockets eventually reached.

Number two: the Goliath tracked mine. Imagine a remote-controlled car. Now imagine it is 4 feet long, 2 feet wide, 1 foot tall, weighs about 650 pounds, and is packed with enough explosive to flip a 30-ton tank into the air. That was the Goliath. The Nazis called it the Leichter Ladungsträger—the light charge carrier. Allied soldiers called it the beetle tank. It looked absurd, a tiny tracked vehicle crawling across the battlefield on miniature treads, trailing a thin wire behind it like some kind of deadly toy. But there was nothing funny about what happened when it reached its target.

The idea was not entirely new. During the First World War, the French had experimented with small remote-controlled tracked vehicles designed to carry explosives into enemy trenches. In 1940, after the fall of France, the Germans recovered a prototype of one such vehicle near the Seine River. The Wehrmacht’s Ordnance Office looked at it and saw something useful. They handed the project to the Borgward Automotive Company in Bremen and told them to build something similar—something that could carry at least 50 kilograms of high explosives to a target by remote control. Borgward delivered.

The first version, the Sd.Kfz. 302, rolled out in the spring of 1942. It was powered by two small electric motors. It could carry 60 kilograms of explosive. Its top speed was about 6 mph. An operator controlled it from a distance using a joystick box connected to the Goliath by a triple-strand cable that could extend up to 650 meters. Two of the cable strands handled steering. The third detonated the explosive charge. The Goliath was designed as a single-use weapon. You drove it to the target. You pressed the button. The Goliath and the target both ceased to exist.

The concept was ahead of its time. This was a remote-controlled demolition vehicle in 1942—decades before drones became a standard part of modern warfare. The Goliath was intended for multiple roles: destroying enemy tanks by driving underneath them and detonating, blowing up fortified positions, demolishing bridges, disrupting dense concentrations of infantry. In theory, it gave a small team of operators the ability to deliver a devastating explosion to a precise point without risking anyone’s life.

In practice, the Goliath had serious problems. The electric motors were expensive to build and unreliable in the field. The vehicle had terrible ground clearance—only about 4½ inches—which meant that rocks, logs, ruts, or any significant terrain feature could stop it cold. The thin armor, only 5 millimeters of mild steel, offered almost no protection. A single rifle bullet could disable it. And the control cable was its greatest weakness. Enemy soldiers quickly learned that if they could see the wire, they could cut it. Once the cable was severed, the Goliath became a useless lump of explosive sitting in the middle of a battlefield doing nothing.

A later version, the Sd.Kfz. 303, replaced the electric motors with a gasoline engine built by Zündapp. This made the vehicle cheaper, more reliable, and slightly faster. It could carry up to 100 kilograms of explosive, but it still suffered from the same fundamental problems: slow, fragile, vulnerable cable. The Goliath saw action on every front except North Africa. It was used at Kursk in 1943, where it was deployed to help clear Soviet minefields ahead of German tank destroyers. It appeared at Anzio in January 1944, where American troops encountered it during the beach landings. It showed up at Normandy in June 1944, scattered across Utah Beach, and it was used during the Warsaw Uprising in August 1944, where Polish Home Army fighters discovered that cutting the control cable turned the mighty Goliath into an expensive paperweight.

In all, about 7,564 Goliaths were manufactured during the war. Despite the high production numbers, the weapon was not considered a tactical success. It was too expensive for a disposable weapon, too slow to avoid defensive fire, and too dependent on a physical cable that any soldier with a pair of wire cutters could defeat. Allied troops found Goliaths fascinating more for entertainment than fear. Captured examples were played with, driven around camps as novelties after the explosive charges were removed. American soldiers used some of them as aircraft tugs for a brief time before the vehicles broke down, because they were never designed for sustained use.

But here is the thing. The Goliath was a failure as a weapon. It was a success as an idea. Every remote-controlled bomb disposal robot, every unmanned ground vehicle, every land drone crawling across the battlefields of Ukraine today owes something to that clumsy little tracked box the Nazis sent wobbling across the fields of Europe 80 years ago. The ancestor of the modern combat drone weighed 650 pounds, moved at walking speed, and could be stopped by a pair of scissors. Sometimes the future starts with a failure.

Number three: the V1 flying bomb. Before the V2, there was the V1. And in some ways, the V1 was worse. Not because it was more advanced—it was the opposite. The V1 was crude, cheap, and loud. It was essentially a flying bomb powered by a pulse-jet engine that made a sound unlike anything anyone had ever heard before. A harsh, rhythmic buzzing, like an angry motorboat in the sky, like a giant mechanical insect. The British called it the buzz bomb. They also called it the doodlebug. Those nicknames made it sound almost playful. It was not playful. It killed 6,184 people.

The V1 was 27 feet long with a wingspan of about 17½ feet. It carried an 1,870-pound warhead of amatol high explosive. It flew at speeds of around 400 mph at altitudes between 2,000 and 3,000 feet. It was launched from ramps along the French and Dutch coasts, pointed at London, and sent on its way. There was no pilot. There was no radio guidance. The V1 used a simple gyroscopic autopilot and a small propeller-driven odometer on its nose that counted the number of rotations as it flew. When the counter reached the preset number corresponding to the distance to the target, a mechanism activated. It cut the fuel supply to the engine. The engine stopped. The buzzing stopped. And then silence.

That silence was the most terrifying sound of the war. Because when the buzz stopped, everyone on the ground knew what was coming. The bomb was falling, and you had about 12 seconds to find cover. If you could still hear the buzzing, you were probably safe. The bomb was still flying. It would pass overhead. It was someone else’s problem. But if the buzzing stopped while the bomb was above you, you ran. You dove under a table. You pressed yourself against a wall. You prayed. And then the world shook.

The first V1 attack hit England on the 13th of June, 1944—exactly one week after D-Day. Over the following months, the Luftwaffe launched approximately 9,251 V1s at targets in Britain. Most were aimed at London. Of those, about 2,500 made it through British defenses and hit the city. The rest were shot down by fighter planes, anti-aircraft guns, or brought down by barrage balloons.

The V1 could be intercepted because it flew at a predictable speed and altitude. Fighter pilots learned to fly alongside V1s and tip them over by sliding their wing under the bomb’s wing and rolling it. Others simply shot them down, though this was dangerous because the explosion could damage the pursuing aircraft. Anti-aircraft gunners got better at hitting them as the campaign went on, especially after proximity-fused shells became available.

But enough V1s got through to cause massive damage and massive fear. The attacks drove over a million and a half people out of London. Factories slowed production. Work absenteeism spiked. The constant stress of listening for the buzz, waiting for it to stop, wondering if this one was coming for you, wore people down in ways that conventional bombing did not. At least with a bomber, you knew the attack was happening. You could hear the planes, you could hear the anti-aircraft guns. There was a rhythm to it. The V1 had its own rhythm, and it was the rhythm of dread. Buzz, buzz, buzz—then nothing. Then death.

Croydon, a borough in South London that sat directly under the V1 flight path, was hit 142 times. Entire neighborhoods were flattened. Across London, 6,184 civilians were killed and nearly 18,000 were seriously injured by V1 strikes. The damage to buildings was catastrophic. Tens of thousands of homes were destroyed or made uninhabitable.

The V1 was cheap to produce. That was its real danger. Unlike the V2, which was expensive and complicated, the V1 could be mass-produced quickly using relatively simple technology. The pulse-jet engine had no moving parts in the traditional sense. The airframe was mostly sheet metal and plywood. Germany built more than 30,000 of them. If the war had lasted longer, the numbers would have been far worse.

The V1 campaign ended only because Allied ground forces overran the launch sites in France and the Netherlands. Once those ramps were captured, the buzz bombs stopped. London could breathe again—but the people who survived never forgot that sound, and they never forgot the silence that followed it.

Number four: the Flammenwerfer 35 and 41. Fire has been used as a weapon since the beginning of human warfare. The Greeks used it. The Romans used it. The Byzantines had Greek fire. But the modern flamethrower—the kind that straps to a soldier’s back and sends a pressurized stream of burning liquid across a battlefield—that was a German invention. And in World War II, the Nazis used it with devastating effect.

The Flammenwerfer 35 was the standard German flamethrower at the start of the war. It was a crew-served weapon, meaning it required two soldiers to operate. One carried the fuel tank on his back. The other aimed and fired the projector. The system could throw a stream of burning fuel approximately 25 to 30 meters. The fuel was a thickened mixture that stuck to whatever it touched—skin, clothing, walls. Once it was burning on you, you could not put it out. Water made it worse. Rolling on the ground spread it. The only thing that stopped it was smothering it completely, and by the time you managed that, the damage was already done.

The Flammenwerfer 41 was an improvement—lighter, more compact, capable of being operated by a single soldier. It had a reduced range compared to the 35 but made up for it in portability. A single infantryman could carry it into a building, down a trench, or through a bunker complex. Flamethrowers were used extensively on the Eastern Front. The fighting there was brutal beyond anything seen in Western Europe. Cities were fought over room by room, building by building, floor by floor. Stalingrad, Sevastopol, Warsaw. The flamethrower became the weapon of choice for clearing defensive positions that could not be taken by conventional means—bunkers that machine guns could not silence, basements where soldiers would fight to the last man, trenches that had been reinforced with concrete and timber until they were nearly impervious to grenades.

The flamethrower solved all of these problems. A burst of liquid fire into an enclosed space ended the fight immediately. The defenders either burned to death, suffocated from the oxygen the fire consumed, or came running out in flames, screaming. The psychological impact was immense. Soldiers on both sides who saw flamethrowers in action described it as the most horrifying weapon they had ever encountered. The smell of burning fuel and burning flesh. The screams that stopped too quickly or went on too long. The sight of human beings turned into torches, staggering, falling, thrashing on the ground while their comrades could do nothing.

Both sides developed an unwritten rule about flamethrower operators. If you were captured carrying a flamethrower, you were not taken prisoner. You were shot on the spot—sometimes worse. This applied to both the Germans and the Allies. Flamethrower operators knew this. They volunteered for the job anyway. They also knew that the fuel tanks on their backs made them priority targets. A single bullet to the tank could turn the operator into the same kind of fireball he was trying to create. The average combat lifespan of a flamethrower operator on the Eastern Front was measured in minutes, not hours.

The Germans were not the only ones who used flamethrowers. The Americans used them extensively in the Pacific. The British used them in North Africa and Europe. The Soviets had their own versions. But the German models were among the most refined and widely deployed of the war, and they were used in some of the most brutal fighting in human history.

The Flammenwerfer was not a wonder weapon. It was not a secret weapon. It was a simple, horrible, effective weapon that turned the most basic force of nature—fire—into something that could be aimed, projected, and delivered directly onto another human being from 25 meters away. And for all the technological marvels the Nazis created, nothing they built was more feared by the soldiers who faced it than the man with the flame on his back.

Number five: the Gustav and Dora railway guns. Some weapons are terrifying because they are invisible. The V2 arrived before its sound. The butterfly bomb lay hidden in the grass. The Schwerer Gustav—the Heavy Gustav—was terrifying for the opposite reason. You could see it. You could not miss it. It was the largest gun ever fired in combat, 80 centimeters in caliber. That is 31.5 inches. The barrel was over 30 meters long. The entire weapon, when fully assembled, weighed 1,350 tons. It sat on a pair of parallel railway tracks supported by 80 wheels on 40 axles. To transport it, you needed a train of 25 cars stretching 1.5 kilometers. To assemble it, you needed 250 men working for three days or more. To operate it, you needed a crew of hundreds. To protect it from air attack, you needed two entire anti-aircraft battalions. The total number of personnel required to deploy, assemble, service, protect, and fire the Gustav was approximately 4,000 men.

The gun was built by the Krupp company in the late 1930s. It was originally designed to destroy the fortifications of the French Maginot Line—the most heavily defended border in the world at the time. The idea was simple. Build a gun so enormous that no fortification could withstand its shells. Krupp’s engineers calculated that they would need an 80-centimeter weapon firing a 7-ton projectile from a 30-meter barrel to punch through the Maginot Line’s defenses. The shell needed to penetrate 7 meters of reinforced concrete or a full meter of steel armor plate. The Gustav could do both.

But by the time the gun was ready, the Maginot Line was irrelevant. The German army had already bypassed it by invading through Belgium. France had fallen. The Gustav had nothing to shoot at. It sat in storage until 1942, when it was sent to the Eastern Front for the Siege of Sevastopol in Crimea. That siege was the Gustav’s only combat deployment. And what it did there was beyond anything the defenders could have imagined.

The gun arrived in Crimea in early March 1942. A special railway spur had to be built from the existing line to a firing position north of the city. Four semicircular tracks were laid so the gun could traverse. Installation took until early June. On the 5th of June, the Gustav fired its first round at Sevastopol. The gun could fire two types of ammunition: a high-explosive shell weighing 4,800 kilograms with a range of 47 kilometers, and an armor-piercing shell weighing 7,100 kilograms with a range of 38 kilometers. Both types required a crane to load them into the breech. The rate of fire was painfully slow—roughly one round every 30 to 45 minutes—but when those rounds hit, the results were devastating.

The Gustav engaged coastal batteries, fortified positions, and ammunition stores around the city. On the 6th of June, it scored what may be the most extraordinary single shot in the history of artillery. An armor-piercing shell struck an underground ammunition magazine called White Cliff, located beneath Severnaya Bay. The magazine was buried roughly 30 meters below the surface, protected by the water of the bay above and 10 meters of reinforced concrete around it. The shell punched through the water, through the rock, through the concrete, and detonated inside the magazine. The explosion destroyed the entire facility. One shell, 30 meters underground, through water and reinforced concrete. Nothing else in the history of warfare has ever done that.

The Gustav fired a total of 48 rounds during the siege. By the time the city fell on the 4th of July, its original barrel was worn out from the stress of firing such massive projectiles. A spare barrel was fitted, and the original was sent back to the Krupp factory for relining. After Sevastopol, the gun was disassembled and moved north toward Leningrad, where another siege was underway. It was placed in a firing position near the city, but the planned attack was canceled. The Gustav sat idle through the winter of 1942 into 1943. It was eventually disassembled, placed in storage, and destroyed by the Germans near the end of the war to prevent it from falling into Allied hands.

A second gun, called Dora, was also built. It was reportedly deployed near Stalingrad in late 1942 but may never have actually fired. The histories are murky on this point. A third, even larger gun called Langer Gustav was planned but never completed before Allied bombing destroyed the factory where it was being built.

The Gustav was an engineering marvel and a strategic disaster. It consumed enormous resources—thousands of men and women working for months to transport, assemble, protect, and fire a weapon that managed to hit approximately 48 targets in its entire career. As a cost-effective instrument of war, it was laughable. But as a statement of what human engineering could accomplish when paired with unlimited ambition and no concern for practicality, it was staggering. The largest gun ever fired in anger. 1,350 tons of steel and explosive intent. And a single shell that traveled through water, earth, and concrete to destroy a target 30 meters below the surface of the earth. Nothing like it will ever be built again.

Number six: Zyklon B. This is the hardest entry on this list. Not because the weapon was sophisticated—it was not. Zyklon B was a commercial pesticide: hydrogen cyanide absorbed into granules of diatomaceous earth, packed into sealed metal tins. It was originally designed to kill lice and other pests in warehouses, grain stores, and ships. It was effective, widely available, and cheap. The Nazis turned it into the primary killing agent of the Holocaust. Approximately 1.1 million people were murdered with Zyklon B at Auschwitz-Birkenau alone.

The product was developed in the early 1920s. The patent was held by a company called Degesch, which was largely owned by IG Farben, the giant German chemical conglomerate. Two distribution companies handled sales: Tesch and Stabenow, based in Hamburg, supplied the eastern territories and the concentration camps; Heli-Lingler handled western and southern Germany. When the tins were opened and the pellets exposed to air at room temperature, they released hydrogen cyanide gas. In normal commercial use, a warning odorant was added to the pellets to alert handlers to the presence of the poisonous gas. For the versions shipped to the SS, the warning odorant was removed. The Nazis did not want their victims to smell the gas before it was too late.

The first experiments with Zyklon B as a weapon of mass murder took place at Auschwitz in September 1941. SS officers tested the gas on approximately 600 Soviet prisoners of war and 250 sick prisoners in the basement of Block 11 at the main camp. The test was considered successful. Within months, the killing expanded to an industrial scale. Two converted farmhouses at Birkenau, called Bunker 1 and Bunker 2, were turned into gas chambers in early and mid-1942. By 1943, four massive crematorium complexes at Birkenau were operational. Each one contained an undressing room, a gas chamber disguised as a shower room, and cremation ovens.

The process was designed to function with maximum efficiency and minimum resistance. Victims were told they were being taken for delousing and showers. The gas chambers had fake shower heads mounted on the ceilings to maintain the deception. Victims were packed inside, the doors were sealed, and SS personnel dropped Zyklon B pellets through vents in the roof. Death came within minutes—though not quickly enough. Witness accounts described the screaming, the clawing at the walls, the bodies piled highest near the doors where victims had desperately tried to escape.

Between 1942 and 1944, approximately 729 tons of Zyklon B was sold in Germany. About 56 tons of that—roughly 8 percent—went to concentration camps. Auschwitz received 23.8 tons. Only 6 tons were used for their stated purpose of fumigation. The rest went into the gas chambers. A single ton of Zyklon B was enough to kill approximately 312,500 people. The math is not complicated. The volume of Zyklon B shipped to the camps far exceeded any legitimate pest-control need.

The companies involved in manufacturing and distributing the gas claimed after the war that they did not know what it was being used for. The dramatic increase in orders from the camps, combined with the specific request to remove the warning odorant, makes those claims almost impossible to believe. The Sonderkommando—groups of Jewish prisoners forced to remove bodies from the gas chambers and operate the crematoria—staged an uprising in October 1944. They managed to destroy Crematorium 4 and killed several SS guards before being overwhelmed.

In November 1944, SS chief Heinrich Himmler ordered the destruction of the remaining gas chambers and crematoria as the Soviet army advanced. The SS tried to destroy the evidence. They failed. When Allied forces liberated the camps in 1944 and 1945, they found intact gas chambers, thousands of empty Zyklon B tins, and surviving prisoners who could testify to what had happened.

After the war, Bruno Tesch and Karl Weinbacher of Tesch and Stabenow were tried, convicted, and executed in 1946 for their role in supplying Zyklon B to the camps. IG Farben executives were also put on trial at Nuremberg. Some were convicted. Others were acquitted due to insufficient evidence directly linking them to knowledge of the gas chambers. Many of those acquitted went on to hold senior positions in the chemical companies that emerged from IG Farben’s breakup—including BASF, Bayer, and Hoechst.

Zyklon B was not a weapon of war in the traditional sense. No army faced it on the battlefield. It was a weapon of genocide—a commercial pesticide repurposed with cold efficiency, turned against human beings in sealed rooms from which there was no escape. It represents the point where industrial technology met ideological hatred and produced the most systematic mass murder in human history. The empty tins are still on display at Auschwitz. They sit behind glass in neat rows. Small, unremarkable—the kind of thing you might walk past without a second glance if you did not know what they were for.

Number seven: tabun and sarin nerve agents. In 1936, a German chemist named Gerhard Schrader was trying to invent a better pesticide. He worked for IG Farben—the same chemical giant that would later supply Zyklon B to the death camps. Schrader was mixing phosphorus-based compounds, looking for something that could kill the weevils destroying German grain harvests. What he created instead was a substance so toxic that a single drop on the skin could kill a human being. He called it Preparation 9/91.

When German army scientists at the Spandau Citadel in Berlin analyzed the compound, they were stunned. Existing chemical weapons like mustard gas and phosgene took hours or even days to kill their victims. This new substance could kill in 20 minutes. They named it Tabun—after the German word for taboo. Then they classified it as a state secret and handed Schrader a reward of 50,000 Reichsmarks.

Two years later, in 1938, Schrader created something even worse—a compound he called Substance 146. It was twice as toxic as Tabun. He brought it to the Spandau Citadel, where military chemists began studying it with great urgency. The new poison was renamed Sarin—an acronym built from the names of the scientists who developed it: Schrader, Ambros, Ritter, and von der Linde.

Tabun and Sarin were the world’s first nerve agents. They worked by attacking the nervous system. Specifically, they blocked an enzyme called acetylcholinesterase, which normally breaks down the neurotransmitter acetylcholine after it delivers a nerve signal. Without that enzyme, acetylcholine accumulates in the body. Muscles contract uncontrollably. The pupils shrink to pinpoints. Saliva and mucus flood the airways. The victim loses control of their bladder and bowels. Breathing becomes impossible as the muscles of the diaphragm and chest wall seize up. Death comes from suffocation. The victim is conscious through much of it.

Nazi Germany built an entire factory to produce Tabun at a place called Dyhernfurth, in what is now Poland. The factory used concentration camp prisoners as forced labor. Working conditions were extraordinarily dangerous. Accidents with the nerve agent were frequent. Workers were exposed to lethal doses. Some were denied medical treatment. A prisoner named Thaddäus Carol later testified that he was ordered to enter a contaminated filling station without gas protection. He collapsed from Tabun exposure, and atropine injections saved his life. Others were not so lucky.

By mid-1943, Germany had manufactured approximately 12,500 tons of Tabun. Much of it was loaded into artillery shells and aerial bombs. A Sarin production facility was approved for construction at Falkenhagen, about 70 kilometers outside Berlin, but it was never fully completed before the war ended. Estimates suggest that between 500 kilograms and 10 tons of Sarin were actually produced.

Here is the terrifying question: Why did Hitler never use them? Germany had nerve agents in massive quantities. The Allies had nothing comparable. The British and Americans had no idea these substances even existed. If the Nazis had deployed Tabun or Sarin on the battlefield, the initial results would have been catastrophic. Allied gas masks were designed to filter out older chemical weapons like mustard gas and phosgene. They would have provided little or no protection against nerve agents, which could penetrate the skin and did not require inhalation to kill.

Several factors stopped Hitler. After the Battle of Stalingrad, senior Nazis—including Goebbels and Bormann—pushed Hitler to use chemical weapons against the advancing Soviet army. At a meeting in May 1943, Hitler consulted Otto Ambros, an IG Farben executive and chemical weapons expert. Ambros told Hitler that while Germany had 45,000 tons of chemical agent stockpiled, the Allies likely had even more. He suggested that the Americans and British already knew about Tabun and Sarin and had developed their own versions in even greater quantities. This was completely false. The Allies knew nothing about nerve agents. But Ambros may have been misled by the fact that American scientific journals had stopped publishing certain chemical research, which he interpreted as evidence of a secret nerve agent program. In reality, American military censors had been blocking publications about DDT—an insecticide. A misunderstanding about insecticide research may have prevented the deployment of the deadliest chemical weapons ever created up to that point.

Hitler, who had himself been a victim of mustard gas in World War I, was reportedly afraid of chemical retaliation. He ordered increased production of Tabun and Sarin but forbade their transportation to the front lines, fearing that a rogue officer might use them and trigger an Allied chemical response that Germany could not survive. As the war situation grew more desperate, the temptation to use nerve agents grew stronger, but the fear of retaliation held.

After Germany’s surrender, the Allies discovered the Tabun factory at Dyhernfurth. The Soviets got there first and dismantled the entire facility, shipping the machinery back to the Soviet Union. When British and American intelligence officers learned what the Germans had developed, they panicked. An entirely new category of chemical weapon had existed during the war, and the Allies had been completely unaware of it. The chemical arms race that followed would last for decades, paralleling the nuclear arms race in secrecy and danger.

Nerve agents were tested on concentration camp inmates at Sachsenhausen and Natzweiler. They were produced by forced laborers who died from exposure. They were stockpiled by the thousands of tons and loaded into weapons that could have been deployed at any time. And they were never used on the battlefield—not because of morality, but because of a lie told by a chemist and a fear of retaliation that turned out to be based on a misunderstanding about bug spray. That is the story of how the world’s deadliest chemical weapons were invented, mass-produced, and kept in storage by a regime that murdered millions but was afraid to use the one weapon that could have changed the entire course of the war.

Number eight: the Stuka dive bomber with Jericho trumpets. The Junkers Ju 87 Stuka was not the fastest plane in the sky. It was not the most maneuverable. By the middle of the war, it was dangerously obsolete—easy prey for modern fighter aircraft and improved anti-aircraft defenses. But in the early years of World War II, between 1939 and 1941, the Stuka was perhaps the most feared weapon in the German arsenal. And it earned that fear not just with its bombs, but with its scream.

Mounted on the leading edges of the Stuka’s fixed landing gear legs were two small propeller-driven sirens. The Germans called them Jericho trumpets—a reference to the biblical story of the walls of Jericho falling at the sound of trumpets. Each siren had a propeller with a diameter of about 2.3 feet. They were driven entirely by the rushing air as the plane dove. The faster the plane went, the louder the siren screamed. During a near-vertical attack dive at speeds approaching 370 mph, the Jericho trumpets produced an ear-splitting rising wail that could be heard from miles away. The sound was designed to do one thing—create terror—and it worked.

The Stuka’s standard attack profile was a steep dive, often between 60 and 90 degrees, directly at the target. The pilot would spot his target, roll the aircraft over, and plunge nearly straight down. As the plane accelerated in the dive, the Jericho trumpets began their wail. The sound rose in pitch and volume as the speed increased, reaching a crescendo just before the bombs were released and the pilot pulled out of the dive.

On the ground, the experience was nightmarish. You heard the scream growing louder and higher. You could see the plane coming straight at you, growing larger every second. You could not tell where the bombs would land. All you knew was that the sound was getting louder, which meant the plane was getting closer, which meant death was getting closer. Soldiers who survived Stuka attacks described a paralyzing effect. Men who were trained to fight, who had been under fire before, who knew what to do, simply froze. The sound overrode their training. It bypassed their rational minds and triggered a primal fear response. Some ran. Some flattened themselves on the ground and could not move. Some screamed back at the sky. The Stuka did not just drop bombs. It dropped fear first, and then it dropped bombs.

The Stuka made its combat debut during the Spanish Civil War in 1937 with the Luftwaffe’s Condor Legion. It was devastating against unprepared opponents. When World War II began in September 1939, Stukas led the assault on Poland. They destroyed airfields, bridges, communication centers, and troop concentrations with terrible precision. The screaming dive became the signature sound of the Blitzkrieg. It accompanied the fall of Poland, Norway, Denmark, Belgium, the Netherlands, and France. Wherever the Stuka appeared, the ground forces beneath it broke.

But the Jericho trumpets had a downside. The propeller-driven sirens created significant aerodynamic drag, reducing the aircraft’s speed by about 12 to 15 mph. In the early campaigns, when the Luftwaffe had total air superiority and enemy anti-aircraft defenses were weak, this penalty did not matter. But as the war progressed and enemy fighters and flak guns became more effective, that lost speed could mean the difference between life and death for the pilot. During the Battle of Britain in 1940, the Royal Air Force shot down dozens of Stukas. The slow, predictable dive made the plane a sitting duck for faster fighters attacking from above. The Luftwaffe was forced to withdraw the Stuka from the battle. After that, the Jericho trumpets were gradually removed from many aircraft. Later models used a different approach—attaching small whistles directly to the bombs themselves. The bombs would scream as they fell, achieving a similar psychological effect without slowing down the aircraft.

Over 6,000 Stukas were built between 1936 and 1944. The aircraft continued to serve on the Eastern Front and in the Mediterranean throughout the war, transitioning from dive bomber to ground-attack aircraft. Hans-Ulrich Rudel, the most decorated German serviceman of the war, flew the Stuka for most of his career, personally destroying over 500 tanks and countless other targets. The Stuka remained in service until the very end of the war in 1945, long after it should have been replaced.

The Jericho trumpets were eventually abandoned, but their legacy outlived the aircraft that carried them. The sound of the Stuka dive became one of the most recognizable sound effects in cinema history. Every time you hear a diving plane in a movie, the rising scream you hear is almost certainly based on the Jericho trumpet—a weapon designed to create terror on the battlefields of 1939, still creating unease in movie theaters and living rooms more than 80 years later. The CIA even tried to recreate the sirens in the 1950s for use in psychological warfare operations. They tracked down the original designer and searched museums across America looking for intact examples. The sound that terrified a continent had become valuable all over again. Because some weapons kill with explosives, and some weapons kill with fear. The Stuka did both.

Number nine: the butterfly bomb. It weighed 2 kilograms—about 4½ pounds. It was only 8 centimeters long. It fit in the palm of your hand. When it fell from the sky, a thin metal outer shell hinged open and spring-loaded wings popped out, giving it the appearance of a large butterfly. It spun gently as it descended, which armed the fuse. When it hit the ground, one of several things happened. It exploded on impact, sending shrapnel in every direction—lethal within 10 meters, capable of causing serious injury as far as 100 meters away. Or it did not explode. It sat there—on the ground, in a field, on a sidewalk, in a garden, on a playground—waiting.

Some butterfly bombs were fitted with time-delay fuses—clockwork mechanisms that could be set to detonate anywhere from 10 minutes to 60 minutes after landing. Others were fitted with anti-disturbance fuses, which meant they would explode the moment anyone touched them or moved them. This was the true horror of the butterfly bomb. It was not just a weapon. It was a trap. A small, colorful, interesting-looking object lying in the grass or sitting in a doorway—and anyone who picked it up, nudged it with their foot, or simply brushed against it while walking past would set it off.

Children were particularly vulnerable. The bombs looked like toys. They looked like something a curious child would want to pick up and examine. And some of them did. And some of those children died hours or days after the planes had gone, killed by a bomb that had been designed from the very beginning to wait for exactly that moment.

The SD2, its official designation, was one of the first cluster bombs ever used in combat. It was not dropped individually. It was packed into containers called AB250 canisters, each holding between 6 and 108 bomblets. The container was dropped from an aircraft and burst open at a preset altitude, scattering the bomblets across a wide area. Luftwaffe air and ground crews called these containers “devil’s eggs.” When a single bomber dropped multiple containers, hundreds of butterfly bombs could rain down on a target in seconds. They carpeted fields, roads, airfields, and residential neighborhoods. The ones that detonated on impact caused immediate casualties. The ones that did not became minefields.

The butterfly bomb was first used operationally on the 29th of October, 1940, against the Royal Air Force station at Watton in England. The British government immediately recognized the danger and deliberately suppressed news of the attacks and the damage they caused. The fear was that if the Germans realized how effective the weapons were, they would use them more often. The British public was not told about the butterfly bombs. Information about them was classified. This secrecy had a cost—because people did not know what the bombs were. They did not know to avoid them when they found them lying in their neighborhoods.

Bombs were dropped on Ipswich, Grimsby, Cleethorpes, and other towns across Britain. They were used extensively on the Eastern Front. They were dropped on Allied forces in North Africa and the Mediterranean. Luftwaffe consumption of SD2 bomblets increased dramatically as the war went on—from 289,000 in the summer of 1941 to over half a million per month by mid-1943. Millions of these tiny weapons were produced and dropped across Europe.

The bomb’s fuse was deliberately designed to be almost impossible to render safe once it had armed itself. The standard procedure for dealing with an unexploded butterfly bomb was to evacuate the area, surround it with sandbags, and destroy it with a small explosive charge. There was no safe way to pick one up or disarm it. Despite this, people encountered them and died for years after the war ended. The last recorded death from a German butterfly bomb in England occurred on the 27th of November, 1956—more than 11 years after the war ended. An RAF flight lieutenant named Herbert Dening was examining an SD2 at a bomb disposal research site near RAF Hornchurch when it detonated and killed him. Eleven years after the last German plane dropped the last container, the butterfly bomb was still killing people.

That was its design. That was its purpose. Not just to kill in the moment of the attack, but to go on killing long after the battle was over—turning every field, every garden, every street into a place where death waited in something small enough for a child to hold.

Number ten: the Nebelwerfer rocket launchers. By the time you heard it, the rockets were already in the air. There was nothing you could do. The Nebelwerfer—which translates to “fog thrower”—was a family of German multiple rocket launcher systems that fired salvos of high-explosive rockets with a sound that Allied soldiers never forgot and never wanted to hear again. The Americans called them “Screaming Mimis.” The British called them “Moaning Minnies.” The nicknames made them sound harmless. They were not harmless. They were among the most psychologically devastating weapons on any battlefield in the Second World War.

The most common version was the 15 cm Nebelwerfer 41—a six-barreled launcher that could fire all six of its 150-millimeter rockets in approximately 10 seconds. The rockets weighed about 34 kilograms each and had a range of roughly 7,000 meters. They were spin-stabilized in flight, meaning the fins were angled to make the rocket spin as it flew, which improved accuracy somewhat but also produced the distinctive howling, shrieking sound that gave the weapon its terrifying reputation. Each rocket contained about 2 kilograms of high explosive. That does not sound like much compared to a conventional artillery shell, but the Nebelwerfer did not fire one shell. It fired six rockets in quick succession from a single launcher—and on the battlefield, multiple launchers were grouped together into batteries. A single battery could fire dozens of rockets simultaneously. When that happened, the sky screamed.

A larger version, the 21 cm Nebelwerfer 42, fired five rockets of even greater destructive power. There was also the 30 cm Nebelwerfer, which launched enormous rockets from wooden crates that could be set up on the ground without even needing a launcher frame. These were sometimes called “Stuka on foot” because the psychological effect was comparable to a Stuka dive-bombing attack, but delivered from the ground.

The rockets were less accurate than conventional tube artillery. They had a wider spread pattern, which meant they were not ideal for hitting specific point targets. But this weakness was actually a strength when the goal was area suppression. A salvo of Nebelwerfer rockets did not need to be precisely aimed. It blanketed an area with explosions. If enemy infantry was dug into a position, a Nebelwerfer salvo saturated that position with fire, noise, and shrapnel.

The sound was the weapon’s secret advantage. Conventional artillery shells arrive with a whistling sound, followed by the explosion. The Nebelwerfer rocket produced something entirely different—a continuous, ascending shriek that lasted for the entire duration of the rocket’s flight. When multiple rockets were in the air simultaneously, the sound layered and built into something that survivors described as otherworldly—a rising chorus of mechanical screams that seemed to come from everywhere at once. Soldiers who experienced Nebelwerfer barrages reported a terror that went beyond the rational fear of being hit by a projectile. The sound triggered something primal. It felt like the air itself was screaming at you.

The Nebelwerfer was first used in significant numbers during the invasion of the Soviet Union in 1941. It saw extensive service on the Eastern Front throughout the war. It was also deployed in North Africa, Italy, and Northwest Europe. By D-Day in June 1944, the Germans had Nebelwerfer batteries positioned along the Normandy coast. Allied soldiers landing on the beaches and fighting through the hedgerow country of Normandy encountered the screaming rockets regularly. Veterans of those campaigns mentioned the Nebelwerfer more frequently than almost any other German weapon when describing the things that terrified them most. Not because the rockets were more deadly than regular artillery—often they were not—but because the sound never stopped being terrifying. You could get used to rifle fire. You could get used to the crump of mortar rounds. You never got used to the Screaming Mimis.

The Nebelwerfer also had a practical advantage in mobility. The launcher was relatively lightweight and could be towed by a standard vehicle or even moved by its crew. It could be set up quickly, fired, and displaced before enemy counter-battery fire could respond. This shoot-and-scoot capability made the Nebelwerfer difficult to suppress. By the time Allied artillery began firing at the position where the rockets had been launched from, the Nebelwerfer battery was already gone, setting up at a new position to fire again.

Thousands of Nebelwerfer launchers were produced during the war. They were a standard part of the German artillery arsenal, and they were respected by every Allied soldier who ever heard them. Not because they were the most accurate weapon. Not because they delivered the heaviest payload. But because they arrived screaming—and the screaming made you feel like the world was ending, even if the rockets landed 50 meters away. Some weapons kill your body. The Nebelwerfer tried to break your mind first.

These were the 10 weapons. A ballistic missile that arrived before its own sound. A remote-controlled bomb on tracks. A flying engine that told you it was coming with a buzz and told you it had arrived with silence. Liquid fire in a backpack. The largest gun ever fired in combat. A commercial pesticide turned into the instrument of the greatest crime in human history. Invisible poisons that could kill through the skin. A dive bomber fitted with mechanical screams. A cluster bomb disguised as a butterfly. And a rocket launcher whose shrieking sound broke the courage of hardened combat soldiers.

None of these weapons won the war for Nazi Germany. The V2 consumed resources that could have built thousands of fighter planes. The Gustav required 4,000 men to fire 48 rounds. The Goliath could be defeated by a pair of wire cutters. The nerve agents were never deployed on the battlefield. The Stuka was obsolete by 1941. The butterfly bomb was suppressed by the British government to prevent the Germans from knowing how well it worked. The Nebelwerfer was less accurate than a conventional howitzer. But every single one of them killed real people. Civilians shopping at Woolworths. Children picking up shiny objects in the grass. Prisoners in underground gas chambers who were told they were going to take a shower. Soldiers who heard a scream from the sky and could not move.

The weapons of Nazi Germany were products of a regime that believed in total war, fought without moral limits, and treated human life as an acceptable cost for any military advantage, no matter how small. The war ended in May 1945. The factories stopped. The rockets stopped falling. The gas chambers were dynamited. The railway guns were scrapped. But the legacies of these weapons did not end with the surrender.

The V2 became the foundation of the space program. Nerve agents became the chemical arsenals of the Cold War. Cluster munitions—the descendants of the butterfly bomb—are still killing civilians in conflict zones around the world today. The flamethrower principle evolved into napalm. The Stuka’s scream became a stock sound effect in Hollywood. And the empty Zyklon B tins still sit behind glass at Auschwitz—quiet reminders that the most terrifying weapons are not always the biggest or the fastest or the loudest. Sometimes the most terrifying weapon is the smallest. The one you do not see. The one that sits in the grass and waits for someone to come along and pick it up.

That is what makes these weapons different from the battles and the strategies and the generals. The battles ended. The strategies were filed away. The generals wrote their memoirs and died in their beds. But the weapons lived on—in the technology they spawned, in the scars they left, in the silence they created where there used to be a family eating dinner, a child playing in a garden, a city going about its ordinary day. That silence is still there. If you listen carefully enough in the places where these weapons did their work, you can still hear it.

And perhaps the most haunting question is not what these weapons did to the people of the past, but what they have taught us about ourselves. Every drone that circles a modern battlefield, every missile that arcs across a continent, every cluster munition that waits in the soil for a farmer’s plow—they all trace their lineage back to the drawing boards and factory floors of a regime that treated human beings as raw material. The engineers who built them were not monsters in lab coats. They were husbands, fathers, men who went home to dinner and listened to music and kissed their children goodnight. And then they went back to work in the morning and designed something that would kill a child they would never meet.

That is the uncomfortable truth at the heart of this list. The most terrifying weapons in history were not built by madmen. They were built by people who were very good at their jobs and very willing to not ask questions. The V2 was an engineering triumph. The Gustav was a feat of industrial ambition. Zyklon B was a triumph of chemical efficiency. And all of them were pointed at human beings who had done nothing to deserve what was coming.

So the silence is still there. It is in the grass of a garden in Ipswich where a child once played. It is in the rubble of a Woolworths in New Cross where families once shopped on a Saturday afternoon. It is in the tunnels of Mittelbau-Dora where prisoners once dreamed of seeing the sky. It is in the empty tins behind glass at Auschwitz, where the world is still trying to understand how something so small could hold so much evil.

The weapons are gone. The silence remains. And the question that hangs over all of it—the one that history keeps asking and that we keep finding new ways to avoid answering—is this: If we could build them once, what makes us so sure we would never build them again?

What do you think? Did these weapons change the moral calculus of war forever, or did they simply reveal what was always there? Let us know in the comments below.
