The V2 (Template:Langx), with the technical name Aggregat-4 (A4), was the world's first long-range<ref>"Long-range" in the context of the time. See NASA history article Template:Webarchive</ref> guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The Template:Nowrap rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944.<ref>Neufeld, 1995 pp 158, 160–162, 190</ref>
Research of military use of long-range rockets began when the graduate studies of Wernher von Braun were noticed by the German Army. A series of prototypes culminated in the A4, which went to war as the Template:Nowrap. Beginning in September 1944, more than 3,000 Template:Nowrap were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary,Template:Sfn the attacks from Template:Nowrap resulted in the deaths of an estimated 9,000 civilians and military personnel, while a further 12,000 laborers and concentration camp prisoners died as a result of their forced participation in the production of the weapons.<ref name="Thimm">"Am Anfang war die V2. Vom Beginn der Weltraumschifffahrt in Deutschland". In: Utz Thimm (ed.): Warum ist es nachts dunkel? Was wir vom Weltall wirklich wissen. Kosmos, 2006, p. 158, Template:ISBN.</ref>
The rockets travelled at supersonic speeds, impacted without audible warning, and proved unstoppable. No effective defense existed. Teams from the Allied forces—the United States, the United Kingdom, France and the Soviet Union—raced to seize major German manufacturing facilities, procure the Germans' missile technology, and capture the V-2s' launching sites. Von Braun and more than 100 core R&D Template:Nowrap personnel surrendered to the Americans, and many of the original Template:Nowrap team transferred their work to the Redstone Arsenal, where they were relocated as part of Operation Paperclip. The US also captured enough Template:Nowrap hardware to build approximately 80 of the missiles. The Soviets gained possession of the Template:Nowrap manufacturing facilities after the war, re-established Template:Nowrap production, and moved it to the Soviet Union.
Development historyEdit
During the late 1920s, a young Wernher von Braun bought a copy of Hermann Oberth's book, Die Rakete zu den Planetenräumen (The Rocket into Interplanetary Spaces). In 1928 a Raketenrummel or "Rocket Rumble" fad in the popular media was initiated by Fritz von Opel and Max Valier, a collaborator of Oberth, by experimenting with rockets, including public demonstrations of manned rocket cars and rocket planes. The “Rocket Rumble” was highly influential on von Braun as a teenage space enthusiast. He was so enthusiastic after seeing one of the public Opel-RAK rocket car demonstrations, that he constructed and launched his own homemade toy rocket car on a crowded sidewalk and was later taken in for questioning by the local police, until released to his father for disciplinary action.<ref name="Neufield_vonbraun">Template:Cite book</ref>
Starting in 1930, von Braun attended the Technische Hochschule in Charlottenburg (now Technische Universität Berlin), where he assisted Oberth in liquid-fueled rocket motor tests. Von Braun was working on his doctorate when the Nazi Party gained power in Germany. An artillery captain, Walter Dornberger, arranged an Ordnance Department research grant for von Braun, who from then on worked next to Dornberger's existing solid-fuel rocket test site at Kummersdorf. Von Braun's thesis, Construction, Theoretical, and Experimental Solution to the Problem of the Liquid Propellant Rocket (dated 16 April 1934), was kept classified by the German Army and was not published until 1960.<ref>Konstruktive, theoretische und experimentelle Beiträge zu dem Problem der Flüssigkeitsrakete. Raketentechnik und Raumfahrtforschung, Sonderheft 1 (1960), Stuttgart, Germany</ref> By the end of 1934, his group had successfully launched two rockets that reached heights of Template:Cvt.
At the time, many Germans were interested in American physicist Robert H. Goddard's research. Before 1939, German engineers and scientists occasionally contacted Goddard directly with technical questions. Von Braun used Goddard's plans from various journals and incorporated them into the building of the Aggregate (A) series of rockets, named for the German word for mechanism or mechanical system.<ref>Christopher, John (2013). The Race for Hitler's X-Planes. The Mill, Gloucestershire: History Press, p. 110. Template:ISBN?</ref>
After successes at Kummersdorf with the first two Aggregate series rockets, Braun and Walter Riedel began thinking of a much larger rocket in the summer of 1936,<ref name=Ordway>Template:Cite book</ref> based on a projected Template:Cvt thrust engine. In addition, Dornberger specified the military requirements needed to include a 1-ton payload, a range of 172 miles with a dispersion of 2 or 3 miles, and transportable using road vehicles.<ref name=walter />Template:Rp

The four main technologies for the A-4 were large liquid-fuel rocket engines, supersonic aerodynamics, gyroscopic guidance and rudders in jet control.<ref name=Neufeld>Template:Cite book</ref> At the time, Adolf Hitler was not particularly impressed by the V-2; he opined that it was merely an artillery shell with a longer range and much higher cost.<ref name=Irons>Template:Cite book</ref>
During early September 1943, Braun promised the Long-Range Bombardment Commission<ref name=Neufeld />Template:Rp that the A-4 development was "practically complete/concluded",<ref name=Irving />Template:Rp but even by the middle of 1944, a complete A-4 parts list was still unavailable.<ref name=Neufeld />Template:Rp Hitler was sufficiently impressed by the enthusiasm of its developers, and needed a "wonder weapon" to maintain German morale,<ref name=Irons /> so he authorized its deployment in large numbers.<ref>Template:Cite book</ref>
The V-2s were constructed at the Mittelwerk site by prisoners from Mittelbau-Dora, a concentration camp where 20,000 prisoners died.<ref name="Hunt">Template:Cite book</ref><ref name=Beon>Template:Cite book</ref>Template:Page needed<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
In 1943, the Austrian resistance group including Heinrich Maier managed to send exact drawings of the V-2 rocket to the American Office of Strategic Services. Location sketches of V-rocket manufacturing facilities, such as those in Peenemünde, were also sent to the Allied general staff in order to enable Allied bombers to perform airstrikes. This information was particularly important for Operation Crossbow and Operation Hydra, both preliminary missions for Operation Overlord. The group was gradually captured by the Gestapo and most of the members were executed.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>Hansjakob Stehle (5 January 1996).

Technical detailsEdit
The A4 used a 75% ethanol/25% water mixture (B-Stoff) for fuel and liquid oxygen (LOX) (A-Stoff) for oxidizer.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The water reduced the flame temperature, acted as a coolant by turning to steam and augmented the thrust, tended to produce a smoother burn, and reduced thermal stress.<ref name="sutton">Template:Cite book</ref>
Rudolf Hermann's supersonic wind tunnel was used to measure the A4's aerodynamic characteristics and center of pressure, using a model of the A4 within a 40 square centimeter chamber. Measurements were made using a Mach 1.86 blowdown nozzle on 8 August 1940. Tests at Mach numbers 1.56 and 2.5 were made after 24 September 1940.<ref name=hunley/>Template:Rp
At launch the A4 propelled itself for up to 65 seconds on its own power, and a program motor held the inclination at the specified angle until engine shutdown, after which the rocket continued on a ballistic free-fall trajectory. The rocket reached a height of Template:Cvt or 264,000 ft after shutting off the engine.<ref>The History Channel V2 Factory: Nordhausen 070723</ref>
The fuel and oxidizer pumps were driven by a steam turbine, fueled by decomposition of concentrated hydrogen peroxide (T-Stoff) facilitated by a sodium permanganate (Z-Stoff) catalyst. Both the alcohol and oxygen tanks were an aluminum-magnesium alloy.<ref name=Kennedy>Template:Cite book</ref>
The turbopump, rotating at 4,000 rpm, forced the fuel mixture and oxygen into the combustion chamber at 125 liters (33 US gallons) per second, where they were ignited by a spinning electrical igniter. The engine produced 8 tons of thrust during the preliminary stage whilst the fuel was gravity-fed, before increasing to 25 tons as the turbopump pressurised the fuel, lifting the 13.5 ton rocket. Combustion gases exited the chamber at Template:Convert, and a speed of Template:Convert per second. The oxygen to fuel mixture was 1.0:0.85 at 25 tons of thrust; as ambient pressure decreased with flight altitude, thrust increased to 29 tons.<ref name=walter>Template:Cite book</ref><ref name="Zaloga2003p19">Zaloga 2003 p19</ref><ref name=redstone /> The turbopump assembly contained two centrifugal pumps, one for the fuel mixture, and one for the oxygen. The turbine was connected directly by a shaft to the alcohol pump and through a flexible joint and shaft to the oxygen pump.<ref>16:04 https://www.youtube.com/watch?v=EgiMu8A3pi0&t=2036s</ref> The turbopump delivered Template:Convert of alcohol and Template:Convert of liquid oxygen per second to a combustion chamber at Template:Convert.<ref name=hunley/>
Dr. Thiel's 25 ton rocket motor design relied on pump feeding, as opposed to earlier pressure-fed designs. The motor used centrifugal injection, and used both regenerative cooling and film cooling. Film cooling admitted alcohol into the combustion chamber and exhaust nozzle under slight pressure through four rings of small perforations. The mushroom-shaped injection head was removed from the combustion chamber to a mixing chamber, the combustion chamber was made more spherical while being shortened from 6 to 1-foot in length, and the connection to the nozzle was made cone shaped. The resultant 1.5 ton chamber operated at a combustion pressure of Template:Convert. Thiel's 1.5 ton chamber was then scaled up to a 4.5 ton motor by arranging three injection heads above the combustion chamber. By 1939, eighteen injection heads in two concentric circles at the head of the Template:Convert thick sheet-steel chamber, were used to make the 25 ton motor.<ref name=walter />Template:Rp<ref name="hunley">Template:Cite book</ref>
The warhead was a source of trouble. The explosive used was amatol 60/40 detonated by an electric contact fuze. Amatol had the advantage of stability, and the warhead was protected by a thick layer of glass wool, but even so it could still explode during the re-entry phase. The warhead weighed Template:Convert and contained Template:Convert of explosive. The warhead's explosive percentage by weight was 93%, a very high portion compared to other types of munitions.
A protective layer of glass wool was also used for the fuel tanks to prevent the A-4 from forming ice, a problem which plagued other early ballistic missiles such as the balloon tank-design SM-65 Atlas which entered US service in 1959. The tanks held Template:Convert of ethyl alcohol and Template:Convert of oxygen.<ref>War machine encyclopedia, Limited publishing, London 1983 pp. 1690–92 Template:ISBN?</ref>
The V-2 was guided by four external rudders on the tail fins, and four internal graphite vanes in the jet stream at the exit of the motor. These 8 control surfaces were controlled by Helmut Hölzer's analog computer, the {{#invoke:Lang|lang}}, via electrical-hydraulic servomotors, based on electrical signals from the gyros. The Siemens Vertikant LEV-3 guidance system consisted of two free gyroscopes (a horizontal for pitch and a vertical with two degrees of freedom for yaw and roll) for lateral stabilization, coupled with a PIGA accelerometer, or the Walter Wolman radio control system, to control engine cutoff at a specified velocity. Other gyroscopic systems used in the A-4 included Kreiselgeräte's SG-66 and SG-70. The V-2 was launched from a pre-surveyed location, so the distance and azimuth to the target were known. Fin 1 of the missile was aligned to the target azimuth.<ref>Stakem, Patrick H. The History of Spacecraft Computers from the V-2 to the Space Station, 2010, PRB Publishing, Template:ASIN</ref><ref name=hunley/>Template:Rp
Some later V-2s used "guide beams", radio signals transmitted from the ground, as an added input to the Mischgerät analog computer to keep the missile on course in azimuth.<ref>Helmut Hoelzer's Fully Electronic Analog Computer used in the German V2 (A4) rockets. Template:Webarchive (PDF, English, German)</ref> The flying distance was controlled by the timing of the engine cut-off, Brennschluss, ground-controlled by a Doppler system or by different types of on-board integrating accelerometers. Thus, range was a function of engine burn time, which ended when a specific velocity was achieved.<ref name="Zaloga2003p19" /><ref name=walter />Template:Rp<ref name=redstone>Template:Cite book</ref> Just before engine cutoff, thrust was reduced to eight tons, in an effort to avoid any water hammer problems a rapid cutoff could cause.<ref name=sutton/>
Dr. Friedrich Kirchstein of Siemens of Berlin developed the V-2 radio control for motor cutoff (Template:Langx).<ref name=Irving />Template:Rp For velocity measurement, Professor Wolman of Dresden created an alternative of his Doppler<ref name=Pocock />Template:Rp tracking system in 1940–41, which used a ground signal transponded by the A-4 to measure the velocity of the missile.<ref name=Neufeld />Template:Rp By 9 February 1942, Peenemünde engineer Gerd Template:Proper name had documented the radio interference area of a V-2 as Template:Convert around the "Firing Point",<ref name=Klee /> and the first successful A-4 flight on 3 October 1942 used radio control to command motor cutoff.<ref name=Dornberger />Template:Rp Although Hitler commented on 22 September 1943 that "It is a great load off our minds that we have dispensed with the radio guiding-beam; now no opening remains for the British to interfere technically with the missile in flight",<ref name=Irving />Template:Rp about 20% of the operational V-2 launches were beam-guided.<ref name=Dornberger />Template:Rp<ref name=walter />Template:Rp The Operation Pinguin V-2 offensive began on 8 September 1944, when {{#invoke:Lang|lang}}<ref name=Pocock />Template:Rp (English: 'Training and Testing Battery 444') launched a single rocket guided by a radio beam directed at Paris.<ref name=Klee />Template:Rp Wreckage of combat V-2s occasionally contained the transponder for velocity and fuel cutoff.<ref name=Ordway />Template:Rp
The painting of the operational V-2s was mostly a ragged-edged pattern with several variations, but at the end of the war a plain olive green rocket was also used. During tests the rocket was painted in a characteristic black-and-white chessboard pattern, which aided in determining if the rocket was spinning around its longitudinal axis.
The original German designation of the rocket was "V2",<ref name="Thimm" /><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> unhyphenated – exactly as used for any Third Reich-era "second prototype" example of an RLM-registered German aircraft design – but U.S. publications such as Life magazine were using the hyphenated form "V-2" as early as December 1944.<ref name="V2_LIFE">Template:Cite magazine</ref>

Two test launches were recovered by the Allies: the Bäckebo rocket, the remnants of which landed in Sweden on 13 June 1944, and one recovered by the Polish resistance on 30 May 1944<ref># (Polish) Michał Wojewódzki, Akcja V-1, V-2, Warsaw 1984, Template:ISBN</ref> from the Blizna V-2 missile launch site and transported to the UK during Operation Most III.

Various design issues were identified and solved during V-2 development and testing:
- To reduce tank pressure and weight, rapid flow turbopumps were used to increase pressure.<ref name=Neufeld />Template:Rp
- A short and lighter combustion chamber without burn-through was developed by using centrifugal injection nozzles, a mixing compartment, and a converging nozzle to the throat for homogeneous combustion.<ref name=Dornberger />Template:Rp

Air burst problemEdit
Through mid-March 1944, only four of the 26 successful Blizna launches had satisfactorily reached the Sarnaki target area<ref name=Klee>Template:Cite book</ref>Template:Rp due to in-flight breakup ({{#invoke:Lang|lang}}) on re-entry into the atmosphere.<ref name=Johnson>Template:Cite book</ref>Template:Rp (As mentioned above, one rocket was collected by the Polish Home Army, with parts of it transported to London for tests.) Initially, the German developers suspected excessive alcohol tank pressure, but by April 1944, after five months of test firings, the cause was still not determined. Major-General Rossmann, the Army Weapons Office department chief, recommended stationing observers in the target area – Template:Circa May/June, Dornberger and von Braun set up a camp at the centre of the Poland target zone.<ref>Neufeld 1995 pp. 221–222</ref> After moving to the Heidekraut,<ref name=Ordway />Template:Rp SS Mortar Battery 500 of the 836th Artillery Battalion (Motorized) was ordered<ref name=Klee />Template:Rp on 30 August<ref name=Pocock>Template:Cite book</ref> to begin test launches of eighty 'sleeved' rockets.<ref name=Irving />Template:Rp Testing confirmed that the so-called 'tin trousers' – a tube designed to strengthen the forward end of the rocket cladding – reduced the likelihood of air bursts.<ref name=Johnson />Template:Rp<ref name=walter />Template:Rp
ProductionEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} On 27 March 1942, Dornberger proposed production plans and the building of a launching site on the Channel coast. In December, Speer ordered Major Thom and Dr. Steinhoff to reconnoitre the site near Watten. Assembly rooms were established at Peenemünde and in the Friedrichshafen facilities of Zeppelin Works. In 1943, a third factory, Raxwerke, was added.<ref name=walter />Template:Rp
On 22 December 1942, Hitler signed the order for mass production, when Albert Speer assumed final technical data would be ready by July 1943. However, many issues still remained to be solved even by the autumn of 1943.<ref name="Speer">Template:Cite book</ref>
On 8 January 1943, Dornberger and von Braun met with Speer. Speer stated, "As head of the Todt organisation I will take it on myself to start at once with the building of the launching site on the Channel coast," and established an A-4 production committee under Degenkolb.<ref name=walter />Template:Rp
On 26 May 1943, the Long-Range Bombardment Commission, chaired by AEG director Petersen, met at Peenemünde to review the V-1 and V-2 automatic long-range weapons. In attendance were Speer, Air Marshal Erhard Milch, Admiral Karl Dönitz, Col. General Friedrich Fromm, and Karl Saur. Both weapons had reached the final stage of development, and the commission decided to recommend to Hitler that both weapons be mass-produced. As Dornberger observed, "The disadvantages of the one would be compensated by the other's advantages."<ref name=walter />Template:Rp
| Period of production | Production |
|---|---|
| Up to 15 September 1944 | 1,900 |
| 15 September to 29 October 1944 | 900 |
| 29 October to 24 November 1944 | 600 |
| 24 November to 15 January 1945 | 1,100 |
| 15 January to 15 February 1945 | 700 |
| Total | 5200 |
On 7 July 1943, Major General Dornberger, von Braun, and Dr. Steinhof briefed Hitler in his Wolf's Lair. Also in attendance were Speer, Wilhelm Keitel, and Alfred Jodl. The briefing included von Braun narrating a movie showing the successful launch on 3 October 1942, with scale models of the Channel coast firing bunker, and supporting vehicles, including the {{#invoke:Lang|lang}}. Hitler then gave Peenemünde top priority in the German armaments program stating, "Why was it I could not believe in the success of your work? if we had had these rockets in 1939 we should never have had this war..." Hitler also wanted a second launch bunker built.<ref name=walter />Template:Rp
Saur planned to build 2,000 rockets per month, between the existing three factories and the Nordhausen Mittelwerk factory being built. However, alcohol production was dependent upon the potato harvest.<ref name=walter />Template:Rp
A production line was nearly ready at Peenemünde when the Operation Hydra attack occurred. The main targets of the attack included the test stands, the development works, the Pre-Production Works, the settlement where the scientists and technicians lived, the Trassenheide camp, and the harbor sector. According to Dornberger, "Serious damage to the works, contrary to first impressions, was surprisingly small." Work resumed after a delay of four to six weeks, and because of camouflage to mimic complete destruction, there were no more raids during the next nine months. The raid resulted in 735 lives lost, with heavy losses at Trassenheide, while 178 were killed in the settlement, including Dr. Thiel, his family, and Chief Engineer Walther.<ref name=walter />Template:Rp The Germans eventually moved production to the underground Mittelwerk in the Kohnstein where 5,200 V-2 rockets were built with the use of forced labour.<ref>Template:Cite journal</ref>
Launch sitesEdit
After the Operation Crossbow bombing, initial plans for launching from the massive underground Watten, Wizernes and Sottevast bunkers or from fixed pads such as near the Château du Molay<ref name="Jones">Template:Cite book</ref> were dismissed in favour of mobile launching. Eight main storage dumps were planned and four had been completed by July 1944 (the one at Mery-sur-Oise was begun during August 1943 and completed by February 1944).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The missile could be launched practically anywhere, roads running through forests being a particular favourite. The system was so mobile and small that only one {{#invoke:Lang|lang}} was ever caught in action by Allied aircraft, during the Operation Bodenplatte attack on 1 January 1945<ref>Ordway & Sharpe 1979 p. 256</ref> near Lochem by a USAAF 4th Fighter Group aircraft, although Raymond Baxter described flying over a site during a launch and his wingman firing at the missile without hitting it.
It was estimated that a sustained rate of 350 V-2s could be launched per week, with 100 per day at maximum effort, given sufficient supply of the rockets.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Operational historyEdit
The LXV Armeekorps z.b.V. formed during the last days of November 1943 in France commanded by General der Artillerie z.V. Erich Heinemann was responsible for the operational use of V-2.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Three launch battalions were formed in late 1943, Artillerie Abteilung 836 (Mot.), Grossborn, Artillerie Abteilung 485 (Mot.), Naugard, and Artillerie Abteilung 962 (Mot.). Combat operations commenced in Sept. 1944, when training Batterie 444 deployed. On 2 September 1944, the SS Werfer-Abteilung 500 was formed, and by October, the SS under the command of SS Lt. Gen Hans Kammler, took operational control of all units. He formed Gruppe Süd with Art. Abt. 836, Merzig, and Gruppe Nord with Art. Abt. 485 and Batterie 444, Burgsteinfurt and The Hague.<ref>Template:Cite book</ref>
After Hitler's 29 August 1944 declaration to begin V-2 attacks as soon as possible, the offensive began on 7 September 1944 when two were launched at Paris (which the Allies had liberated less than two weeks earlier), but both crashed soon after launch. On 8 September a single rocket was launched at Paris, which caused modest damage near Porte d'Italie.<ref name=Ordway />Template:Rp Two more launches by the 485th followed, including one from The Hague against London on the same day at 6:43 pm.<ref name=Irving />Template:Rp – the first landed at Staveley Road, Chiswick, killing 63-year-old Mrs. Ada Harrison, three-year-old Rosemary Clarke, and Sapper Bernard Browning on leave from the Royal Engineers,<ref name=Middlebrook />Template:Rp and one that hit Epping with no casualties.
The British government, concerned about spreading panic or giving away vital intelligence to German forces, initially attempted to conceal the cause of the explosions by making no official announcement, and euphemistically blaming them on defective gas mains.Template:Sfn The public did not believe this explanation and therefore began referring to the V-2s as "flying gas mains".<ref>Template:Cite journal</ref> The Germans themselves finally announced the V-2 on 8 November 1944 and only then, on 10 November 1944, did Winston Churchill inform Parliament, and the world, that England had been under rocket attack "for the last few weeks".<ref>Template:Cite Hansard</ref>
In September 1944, control of the V-2 mission was transferred to the Waffen-SS and Division z.V.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Positions of the German launch units changed a number of times. For example, Artillerie Init 444 arrived in the southwest Netherlands (in Zeeland) in September 1944. From a field near the village of Serooskerke, five V-2s were launched on 15 and 16 September, with one more successful and one failed launch on the 18th. That same date, a transport carrying a missile took a wrong turn and ended up in Serooskerke itself, giving a villager the opportunity to surreptitiously take some photographs of the weapon; these were smuggled to London by the Dutch Resistance.<ref>Template:Cite book</ref> After that the unit moved to the woods near Rijs, Gaasterland in the northwest Netherlands, to ensure that the technology was not captured by the Allies. From Gaasterland V-2s were launched against Ipswich and Norwich from 25 September (London being out of range). Because of their inaccuracy, these V-2s did not hit their target cities. Soon after that only London and Antwerp remained as designated targets as ordered by Adolf Hitler himself, Antwerp being targeted in the period of 12 to 20 October, after which time the unit moved to The Hague.
TargetsEdit
During the succeeding months about 3,172 V-2 rockets were fired at the following targets:<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
- Belgium, 1,664: Antwerp (1,610), Liège (27), Hasselt (13), Tournai (9), Mons (3), Diest (2)
- United Kingdom, 1,402: London (1,358), Norwich (43),<ref name=Irving />Template:Rp Ipswich (1)
- France, 76: Lille (25), Paris (22), Tourcoing (19), Arras (6), Cambrai (4)
- Netherlands, 19: Maastricht (19)
- Germany, 11: Remagen (Ludendorff Bridge) (11)
Antwerp, Belgium was a target for a large number of V-weapon attacks from October 1944 through to the virtual end of the war in March 1945, leaving 1,736 dead and 4,500 injured in greater Antwerp. Thousands of buildings were damaged or destroyed as the city was struck by 590 direct hits. The largest loss of life by a single rocket attack during the war came on 16 December 1944, when the roof of the crowded Cine Rex was struck, leaving 567 dead and 291 injured.Template:Sfn<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
An estimated 2,754 civilians were killed in London by V-2 attacks with another 6,523 injured,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> which is two people killed per V-2 rocket. The death toll in London did not meet the Nazis' full expectations, during early usage, as they had not yet perfected the accuracy of the V-2, with many rockets being misdirected and exploding harmlessly. Accuracy increased during the war, particularly for batteries where the {{#invoke:Lang|lang}} (radio guide beam) system was used.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Missile strikes that did hit targets could cause large numbers of deaths; 160 were killed and 108 seriously injured in one explosion at 12:26 pm on 25 November 1944, at a Woolworth's department store in New Cross, south-east London.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> British intelligence also helped impede the effectiveness of the Nazi weapon, sending false reports via their Double-Cross System implying that the rockets were over-shooting their London target by Template:Convert.

Possible use during Operation BodenplatteEdit
At least one V-2 missile on a mobile Meillerwagen launch trailer was observed being elevated to launch position by a USAAF 4th Fighter Group pilot defending against the massive New Year's Day 1945 Operation Bodenplatte strike by the Luftwaffe over the northern German attack route near the town of Lochem on 1 January 1945. Possibly, from the potential sighting of the American fighter by the missile's launch crew, the rocket was quickly lowered from a near launch-ready 85° elevation to 30°.<ref>Ordway & Sharpe 1979, p. 256.</ref>
Tactical use on German targetEdit
After the US Army captured the Ludendorff Bridge during the Battle of Remagen on 7 March 1945, the Germans were desperate to destroy it. On 17 March 1945, they fired eleven V-2 missiles at the bridge, their first use against a tactical target and the only time they were fired on a German target during the war.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> They could not employ the more accurate {{#invoke:Lang|lang}} device because it was oriented towards Antwerp and could not be easily adjusted for another target. Fired from near Hellendoorn, the Netherlands, one of the missiles landed as far away as Cologne, Template:Convert to the north, while one missed the bridge by only Template:Convert. They also struck the town of Remagen, destroying a number of buildings and killing at least six American soldiers.<ref name=v2rocket>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Final useEdit
The final two rockets exploded on 27 March 1945. One of these was the last V-2 to kill a British civilian and the final civilian casualty of the war on British soil: Ivy Millichamp, aged 34, killed in her home in Kynaston Road, Orpington in Kent.<ref>Foster, Vicki.

CountermeasuresEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Big Ben and Operation CrossbowEdit
Unlike the V-1, the V-2's speed and trajectory made it practically invulnerable to anti-aircraft guns and fighters, as it dropped from an altitude of Template:Cvt at up to three times the speed of sound at sea level (approximately Template:Convert). Nevertheless, the threat of what was then code-named "Big Ben" was great enough that efforts were made to seek countermeasures. The situation was similar to the pre-war concerns about manned bombers and resulted in a similar solution, the formation of the Crossbow Committee, to collect, examine and develop countermeasures.
Early on, it was believed that the V-2 employed some form of radio guidance, a belief that persisted in spite of several rockets being examined without discovering anything like a radio receiver. This resulted in efforts to jam this non-existent guidance system as early as September 1944, using both ground and air-based jammers flying over the UK. In October, a group had been sent to jam the missiles during launch. By December it was clear these systems were not having any obvious effect, and jamming efforts ended.<ref name="stock25">Jeremy Stocker, "Britain and Ballistic Missile Defence, 1942–2002" Template:Webarchive, pp. 20–28.</ref>
Anti-aircraft gun system (proposed)Edit
General Frederick Alfred Pile, commander of Anti-Aircraft Command, studied the problem and proposed that enough anti-aircraft guns were available to produce a barrage of fire in the rocket's path, but only if provided with a reasonable prediction of the trajectory. The first estimates suggested that 320,000 shells would have to be fired for each rocket. About 2% of these were expected to fall back to the ground unexploded containing almost 90 tons of explosives, which would cause far more damage than the missile. At a 25 August 1944 meeting of the Crossbow Committee, the concept was rejected.<ref name=stock25 />
Pile continued studying the problem and returned with a proposal to fire only 150 shells at a single rocket, with those shells using a new fuse that would greatly reduce the number that fell back to Earth unexploded. Some low-level analysis suggested that this would be successful against 1 in 50 rockets, provided that accurate trajectories were forwarded to the gunners in time. Work on this basic concept continued and developed into a plan to deploy a large number of guns in Hyde Park that were provided with pre-configured firing data for Template:Convert grids of the London area. After the trajectory was determined, the guns would aim and fire between 60 and 500 rounds.<ref name=stock25 />
At a Crossbow meeting on 15 January 1945 Pile's updated plan was presented with some strong advocacy from Roderic Hill and Charles Drummond Ellis. However, the Committee suggested that a test not be performed as no technique for tracking the missiles with sufficient accuracy had yet been developed. By March this had changed significantly, with 81% of incoming missiles correctly allotted to the grid square each fell into, or the one beside it. At a 26 March meeting Pile was directed to a subcommittee with RV Jones and Ellis to further develop the statistics. Three days later the team returned a report stating that if the guns fired 2,000 rounds at a missile there was a 1 in 60 chance of shooting it down. Plans for an operational test began, but as Pile later put it, "Monty beat us to it", as the attacks ended with the Allied capture of their launching areas.<ref name=stock25 />
With the Germans no longer in control of any part of the continent that could be used as a launching site capable of striking London, they began targeting Antwerp. Plans were made to move the Pile system to protect that city, but the war ended before anything could be done.<ref name=stock25 />
Direct attack and disinformationEdit
The only effective defences against the V-2 campaign were to destroy the launch infrastructure—expensive in terms of bomber resources and casualties—or to cause the Germans to aim at the wrong place by disinformation. The British were able to convince the Germans to direct V-1s and V-2s aimed at London to less populated areas east of the city. This was done by sending deceptive reports on the sites hit and damage caused via the German espionage network in Britain, which was secretly controlled by the British (the Double-Cross System).Template:Sfn
According to the BBC television presenter Raymond Baxter, who served with the RAF during the war, in February 1945 his squadron was performing a mission against a V2 launch site, when they saw one missile being launched. One member of Baxter's squadron opened fire on it, without effect.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
On 3 March 1945, the Allies attempted to destroy V-2s and launching equipment in the "Haagse Bos" in The Hague by a large-scale bombardment, but due to navigational errors the Bezuidenhout quarter was destroyed, killing 511 Dutch civilians.
AssessmentEdit
The German V-weapons (V-1 and V-2) cost the equivalent of about US$500 million.<ref>Neufeld 1995, pp. 190–191. Neufeld provides by far the most detailed analysis of the price of the project. Other price estimates of "$2 billion," or "50% more than the Manhattan Project" can be found elsewhere on the internet, but are not credible. For a more detailed analysis, see this article's Talk section.</ref> Given the relatively smaller size of the German economy, this represented an industrial effort equivalent to but slightly less than that of the U.S. Manhattan Project that produced the atomic bomb. 6,048 V-2s were built, at a cost of approximately Template:Reichsmark (Template:GBP in 2011) eachTemplate:Citation needed; 3,225 were launched. SS General Hans Kammler, who as an engineer had constructed several concentration camps including Auschwitz, had a reputation for brutality and had originated the idea of using concentration camp prisoners as slave laborers for the rocket program. More people died manufacturing the V-2 than were killed by its deployment.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The V-2 consumed a third of Germany's fuel alcohol production and major portions of other critical technologies.<ref name=Oberg>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Due to a lack of explosives, some warheads were simply filled with concrete, using the kinetic energy alone for destruction, and sometimes the warhead contained photographic propaganda of German citizens who had died in Allied bombings.<ref name=Irons2>Template:Cite book</ref>
The psychological effect of the V-2 was considerable, as the V-2, traveling faster than the speed of sound, gave no warning before impact (unlike bombing planes or the V-1 flying bomb, which made a characteristic buzzing sound). There was no effective defence and no risk of pilot or crew casualties. An example of the impression it made is in the reaction of American pilot and future nuclear strategist and Congressional aide William Liscum Borden, who in November 1944 while returning from a nighttime air mission over Holland saw a V-2 in flight on its way to strike London:<ref>Template:Cite book</ref><ref>Template:Cite book</ref> "It resembled a meteor, streaming red sparks and whizzing past us as though the aircraft were motionless. I became convinced that it was only a matter of time until rockets would expose the United States to direct, transoceanic attack."<ref>Template:Cite book</ref>
With the war all but lost, regardless of the factory output of conventional weapons, the Nazis resorted to V-weapons as a tenuous last hope to influence the war militarily (hence Antwerp as V-2 target), as an extension of their desire to "punish" their foes and most importantly to give hope to their sympathizers with their miracle weapon.<ref name=Irons /> The V-2 did not affect the outcome of the war, but it resulted in the development of the intercontinental ballistic missiles of the Cold War, which were also used for space exploration.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Unfulfilled plansEdit
A submarine-towed launch platform was tested successfully, making it the prototype for submarine-launched ballistic missiles. The project codename was {{#invoke:Lang|lang}} ("Test stand XII"), sometimes termed the rocket U-boat. If deployed, it would have allowed a U-boat to launch V-2 missiles against United States cities, though only with considerable effort (and limited effect).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Hitler, in July 1944 and Speer, in January 1945, made speeches alluding to the scheme,<ref>Article in San Diego Times c.25 July 1944</ref> though Germany did not possess the capability to fulfill these threats. These schemes were met by the Americans with Operation Teardrop.Template:Citation needed
While interned after the war by the British at CSDIC camp 11, Dornberger was recorded saying that he had begged the Führer to stop the V-weapon propaganda, because nothing more could be expected from one ton of explosive. To this Hitler had replied that Dornberger might not expect more, but he (Hitler) certainly did.Template:Citation needed
According to decrypted messages from the Japanese embassy in Germany, twelve dismantled V-2 rockets were shipped to Japan.<ref>Besant, John Stalin's Silver concerning the sinking of SS John Barry near Aden in 1944</ref> These left Bordeaux in August 1944 on the transport U-boats Template:GS and Template:GS, which reached Jakarta in December 1944. A civilian V-2 expert was a passenger on Template:GS, bound for Japan in May 1945 when the war ended in Europe. The fate of these V-2 rockets is unknown.Template:Citation needed
Post-war useEdit
At the end of the war, a competition began between the United States and the USSR to retrieve as many V-2 rockets and staff as possible.<ref>"We Want with the West", Time Magazine, 9 December 1946.</ref> Three hundred rail-car loads of V-2s and parts were captured and shipped to the United States and 126 of the principal designers, including Wernher von Braun and Walter Dornberger, were captives of the Americans. Von Braun, his brother Magnus von Braun, and seven others decided to surrender to the United States military (Operation Paperclip) to ensure they were not captured by the advancing Soviets or shot dead by the Nazis to prevent their capture.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
After the Nazi defeat, German engineers were relocated to the United States, the USSR, France and the United Kingdom where they further developed the V-2 rocket for military and civilian purposes.<ref>Template:Cite book</ref> The V-2 rocket also laid the foundation for the liquid fuel missiles and space launchers used later.<ref>Template:Cite book</ref>
United StatesEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}}
Operation Paperclip recruited German engineers and Special Mission V-2 transported the captured V-2 parts to the United States. At the close of the Second World War, more than 300 rail cars filled with V-2 engines, fuselages, propellant tanks, gyroscopes, and associated equipment were brought to the railyards in Las Cruces, New Mexico, so they could be placed on trucks and driven to the White Sands Proving Grounds, also in New Mexico.
In addition to V-2 hardware, the U.S. Government delivered German mechanization equations for the V-2 guidance, navigation, and control systems, as well as for advanced development concept vehicles, to U.S. defence contractors for analysis. During the 1950s, some of these documents were useful to U.S. contractors in developing direction cosine matrix transformations and other inertial navigation architecture concepts that were applied to early U.S. programs, such as the Atlas and Minuteman guidance systems as well as the Navy's Subs Inertial Navigation System.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
A committee was formed with military and civilian scientists to review payload proposals for the reassembled V-2 rockets. By January 1946, the U.S. Army Ordnance Corps invited civilian scientists and engineers to participate in developing a space research program using the V-2. The committee was initially named the "V2 Rocket Panel", then the "V2 Upper Atmosphere Research Panel", and finally the "Upper Atmosphere Rocket Research Panel".<ref>See: Johan A.M. Bleeker, Johannes Geiss, and Martin C.E. Huber, ed.s, The Century of Space Science, vol. 1 (Dordrecht, Netherlands: Kluwer Academic Publishers, 2001) p. 41. Template:Webarchive See also: SpaceLine.org Template:Webarchive</ref> This resulted in an eclectic array of experiments that flew on V-2s and helped prepare for American manned space exploration. Devices were sent aloft to sample the air at all levels to determine atmospheric pressures and to see what gases were present. Other instruments measured the level of cosmic radiation.
Only 68 percent of the V-2 trials were considered successful.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> On 29 May 1947, a Modified V-2 had an error in its guidance, and landed near Juarez, Mexico, causing an international incident.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The U.S. Navy attempted to launch a German V-2 rocket at sea—one test launch from the aircraft carrier USS Midway was performed on 6 September 1947 as part of the Navy's Operation Sandy. The test launch was a partial success; the V-2 went off the pad but splashed down in the ocean only some Template:Cvt from the carrier. The launch setup on the Midway's deck is notable in that it used foldaway arms to prevent the missile from falling over. The arms pulled away just after the engine ignited, releasing the missile. The setup may look similar to the R-7 Semyorka launch procedure but in the case of the R-7 the trusses hold the full weight of the rocket, rather than just reacting to side forces.
The PGM-11 Redstone rocket is a direct descendant of the V-2.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

The USSR captured a number of V-2s and staff, letting them stay in Germany for a time.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The first work contracts were signed in the middle of 1945. During October 1946 (as part of Operation Osoaviakhim) they were obliged to relocate to Branch 1 of NII-88 on Gorodomlya Island in Lake Seliger where Helmut Gröttrup directed a group of 150 engineers.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In October 1947, a group of German scientists supported the USSR in launching rebuilt V-2s in Kapustin Yar. The German team was indirectly overseen by Sergei Korolev, one of the leaders of the Soviet rocketry program.
The first Soviet missile was the R-1, a duplicate of the V-2 manufactured completely in the USSR, which was launched first during October 1948. From 1947 until the end of 1950, the German team elaborated concepts and improvements for extended payload and range for the projects G-1, G-2 and G-4. The German team had to remain on Gorodomlya island until as late as 1952 and 1953. In parallel, Soviet work emphasized larger missiles, the R-2 and R-5, based on further developing the V-2 technology with using ideas of the German concept studies.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Details of Soviet achievements were unknown to the German team and completely underestimated by Western intelligence until, in November 1957, the satellite Sputnik 1 was launched successfully to orbit by the Sputnik rocket based on R-7, the world's first intercontinental ballistic missile.<ref>Template:Cite book</ref>Template:Page needed

Between May and September of 1946, CEPA, the forerunner to today's French space agency CNES, undertook the recruitment of approximately thirty German engineers, who had previous experience working on rocket programs for Nazi Germany at the Peenemünde Army Research Center.<ref>Template:Cite book</ref> Much like their counterparts in the United Kingdom, the United States, and the Soviet Union, France's objective was to acquire and advance the rocket technology developed by Germany during World War II. The initial initiative, known as the Super V-2 program, had plans for four rocket variants capable of achieving ranges of up to Template:Convert and carrying warheads weighing up to Template:Convert. However, this program was canceled in 1948.
From 1950 to 1969, the research done on the Super V-2 program was repurposed to develop the Véronique sounding rocket, which became the first liquid-fuel research rocket in Western Europe and was ultimately capable of carrying a Template:Convert payload to an altitude of Template:Convert.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The Véronique program then led to the Diamant rocket and the Ariane rocket family.
UKEdit
During October 1945, the Allied Operation Backfire assembled a small number of V-2 missiles and launched three of them from a site in northern Germany. The engineers involved had already agreed to relocate to the US when the test firings were complete. The Backfire report, published in January 1946, contains extensive technical documentation of the rocket, including all support procedures, tailored vehicles and fuel composition.<ref name="backfireR">Template:Cite book</ref>
In 1946, the British Interplanetary Society proposed an enlarged man-carrying version of the V-2, named Megaroc. It could have enabled sub-orbital spaceflight similar to, but at least a decade earlier than, the Mercury-Redstone flights of 1961.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
