V-2 rocket — Ballistic
Open in interactive gallery →

The V-2 rocket (German: Vergeltungswaffe 2, "Vengeance Weapon 2") was the world's first ballistic missile to enter in-service use. Designed by Wernher von Braun and a team at the Peenemünde Army Research Center in Germany during 1937-1944, the V-2 was a 14-tonne liquid-fuelled rocket that could carry a 1-tonne high-explosive warhead about 200 miles (320 km) on a ballistic trajectory peaking at about 50 miles (80 km) altitude — the edge of space. About 5,200 V-2s were built between 1944 and 1945; some 3,170 were launched in combat, primarily against London, Antwerp, and other Allied targets. The V-2 was the technological foundation for both the post-war U.S. and Soviet space programmes.

The V-2's design integrated three breakthrough technologies. First, the liquid-fuelled rocket motor — burning liquid oxygen and an ethyl alcohol/water fuel — produced 25,000 kgf of thrust, more than double any earlier rocket motor. Second, the inertial guidance system used analog gyroscopes and integrating accelerometers to steer the rocket in flight without ground control. Third, the airframe used graphite-carbon vanes in the rocket exhaust for thrust-vectored steering during the boost phase, with conventional aerodynamic fins for the unpowered ballistic descent. All three technologies were unprecedented in 1944 and all three carried directly into post-war U.S. and Soviet ICBM development.

The first in-service V-2 launch on 8 September 1944 hit Paris; subsequent launches against London began on the same day. Over the next eight months V-2s killed about 9,000 people in the U.K. and Belgium and injured about 25,000 more. The weapon's military effectiveness was modest compared with conventional bombing — accuracy was poor (CEP about 4-7 km), the 1-tonne warhead was small relative to V-2 cost, and the supersonic ballistic trajectory gave no warning to air-raid sirens — but the long-range-terror value was major. Manufacturing took place at the Mittelwerk underground factory near Nordhausen, where about 20,000 forced labourers (mostly from the Mittelbau-Dora concentration camp) died in production conditions — more victims than the V-2 caused in target cities.

Post-war the V-2 became the foundation of both major rocket programmes. The U.S. Army moved von Braun and 1,500 German engineers to White Sands, then to Huntsville, Alabama, where they built up the Redstone, Jupiter-C, and eventually Saturn V rocket families. The Soviet Union captured remaining V-2 hardware at Mittelwerk and used it to seed Sergei Korolev's R-1 (a direct V-2 copy), R-2, R-7 Semyorka (which orbited Sputnik 1 in 1957), and the entire Vostok / Soyuz lineage. Modern SpaceX Falcon 9 rockets and every other liquid-fuelled launch vehicle trace their ancestry directly to the V-2 design.

For Kids — a shorter, friendlier version

The V-2 rocket was Germany's secret weapon at the end of World War II. It was the world's first long-range guided rocket — and the first machine to reach outer space. Each V-2 stood about 46 feet tall (taller than a 4-story building) and weighed 27,000 pounds when full of fuel.

Nazi Germany launched about 3,200 V-2 rockets between September 1944 and May 1945, mostly aimed at London and other European cities. The V-2's flight was very fast — about 3,400 mph at the top, more than four times the speed of sound. People on the ground had no warning; the rocket arrived faster than its own sound, so the explosion happened first and the roar came after.

The V-2 was a weapon, but its lasting importance was as a spaceflight pioneer. The V-2 was the first machine built by humans to reach space (over 62 miles up).

When the war ended, America and the Soviet Union both grabbed V-2 rockets and engineers. Wernher von Braun, the V-2's chief designer, moved to America and later helped build NASA's Saturn V rocket — the one that sent astronauts to the Moon.

The V-2 is called the grandfather of the Space Age. Every rocket flown since — from Apollo to SpaceX Falcon 9 — uses the basic ideas the V-2 invented. A few V-2 rockets survive in museums today: one each at the Smithsonian (Washington DC), the Imperial War Museum (London), and the German Museum (Munich). Walking past one is impressive — the rocket is huge and dark.

Kids’ Questions

How did the V-2 lead to NASA?

When World War II ended in May 1945, both the United States and the Soviet Union raced to capture V-2 rockets, parts, and the engineers who built them. The U.S. captured Wernher von Braun (the V-2's chief designer) and about 1,500 German rocket engineers in an operation called Operation Paperclip. Von Braun moved to America and later became the director of NASA's Marshall Space Flight Center. He led the team that built the Saturn V — the rocket that sent astronauts to the Moon in 1969. The Soviets got their own V-2 engineers and built their R-7 rocket, which launched Sputnik in 1957.

Did the V-2 really go to space?

Yes — the V-2 was the first man-made object to reach what we now call space. The international definition of space is 62 miles above Earth's surface (called the Kármán line). The V-2 routinely flew above 100 miles up — well into space — during its 5-minute flights. The first V-2 flight to reach space was on June 20, 1944. So strictly speaking, the Space Age began in 1944, decades before Sputnik (1957) or Apollo 11 (1969). The V-2 also became the first machine to take photographs of Earth from space — a series of pictures taken in 1946 from a captured V-2 launched in New Mexico.

Variants

A-4 / V-2 (production)
Production designation. About 5,200 built between January 1944 and the end of WWII. 14 tonnes mass, 1-tonne warhead, 320 km range, peak altitude 80-90 km.
A-9 (planned, never built)
Planned winged V-2 derivative for trans-Atlantic strikes against the United States. Development paused in 1944 to focus on production V-2s; never reached prototype hardware.
Post-war Hermes A-1 (U.S.)
U.S. Army post-war re-build of captured V-2s at White Sands as a research vehicle. About 70 launches between 1946 and 1952; provided baseline data for the Redstone and follow-on programmes.

Notable Operators

Wehrmacht (Heer 444)
Sole wartime in-service user. The German Army's special V-2 launch units operated mobile launch trucks and fixed launch sites in the Netherlands, Belgium, France, and Germany. About 3,170 V-2s launched in combat between September 1944 and March 1945.
U.S. Army (post-war)
Captured ~70 V-2s + supporting hardware at Mittelwerk in 1945, transferred to White Sands Missile Range, New Mexico. Wernher von Braun and 1,500 German engineers came under Operation Paperclip. The captured V-2 fleet seeded the Redstone, Jupiter-C, and Saturn V programmes.
Soviet Union (post-war)
Captured remaining V-2 hardware at Mittelwerk (after the U.S. Army withdrawal). Seeded Sergei Korolev's R-1 (V-2 copy), R-2, R-7 Semyorka, and the entire Vostok/Soyuz launch-vehicle lineage. Sputnik 1 launched on a direct V-2 descendant on 4 October 1957.

Frequently Asked Questions

What was the V-2 rocket?

The world's first in-service ballistic missile — a liquid-fuelled rocket capable of carrying a 1-tonne warhead about 200 miles. Designed by Wernher von Braun's team at Peenemünde 1937-1944. About 5,200 produced; 3,170 launched in combat against Allied cities. The V-2 was also the first man-made object to reach space (defined as above 100 km / Kármán line) on a 1944 vertical test flight.

Who designed the V-2?

A team led by Wernher von Braun at the Peenemünde Army Research Center on Usedom Island, Germany, between 1937 and 1944. Major contributors included Walter Thiel (rocket engine), Walter Dornberger (programme management), and Hermann Oberth (theoretical foundations). Most of the senior team came to the U.S. via Operation Paperclip after the war.

How was the V-2 used in combat?

The V-2 was launched at Allied population centres — primarily London (1,402 launches), Antwerp (1,664 launches), and Paris (a small number) — between September 1944 and March 1945. Combat effectiveness was modest: ~9,000 killed and ~25,000 injured in target cities, far fewer than conventional Allied bombing was inflicting on Germany at the time.

How did the V-2 lead to space rockets?

The V-2's three breakthrough technologies — liquid-fuelled rocket motor, inertial guidance, thrust-vectoring control vanes — all carried directly into post-war U.S. and Soviet rocket programmes. Wernher von Braun's V-2 team built the U.S. Army Redstone, Jupiter-C, and Saturn family that put astronauts on the Moon. Sergei Korolev's V-2-derived R-7 Semyorka launched Sputnik 1 in 1957 and is still the basis of today's Soyuz launch vehicle.

Are any V-2s preserved?

Yes — about a dozen original V-2s survive worldwide. Notable examples: Imperial War Museum London, Smithsonian's Steven F. Udvar-Hazy Center, U.S. Army Aviation Museum (Fort Rucker), Deutsches Museum Munich, Peenemünde Historical Technical Museum, and the U.S. Air Force Museum at Wright-Patterson AFB.
