). Dr. Thiel's development of the 25 ton rocket motor relied on pump feeding, rather than on the earlier pressure feeding. The motor used centrifugal injection, while using 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 1.52 MPa (220 psi). 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 3 mm (0.12-inch) thick sheet-steel chamber, were used to make the 25 ton motor.

The warhead weighed and contained of explosive. The warhead's percentage by weight that was explosive was 93%, a very high percentage when compared with other types of munition. A protective layer of glass wool was also used for the fuel tanks so the A-4 did not have a tendency to form ice, a problem which plagued other early ballistic missiles such as the balloon tank-design

problems a rapid cutoff could cause. Dr. Friedrich Kirchstein of Siemens of Berlin developed the V-2 radio control for motor-cut-off (german: Brennschluss). For velocity measurement, Professor Wolman of Dresden created an alternative of his Doppler tracking system in 1940–41, which used a ground signal transponded by the A-4 to measure the velocity of the missile. By 9 February 1942, Peenemünde engineer Gerd had documented the radio interference area of a V-2 as around the "Firing Point", and the first successful A-4 flight on 3 October 1942, used radio control for . 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", about 20% of the operational V-2 launches were beam-guided. The Operation Pinguin V-2 offensive began on 8 September 1944, when (English: 'Training and Testing Battery 444') launched a single rocket guided by a radio beam directed at Paris. Wreckage of combat V-2s occasionally contained the transponder for velocity and fuel cutoff. 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 also appeared. 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. Esquema de la V-2

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 – May/June, Dornberger and von Braun set up a camp at the centre of the Poland target zone. After moving to the Heidekraut, SS Mortar Battery 500 of the 836th Artillery Battalion (Motorized) was ordered on 30 August to begin test launches of eighty 'sleeved' rockets. 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.

However, many issues still remained to be solved even by the autumn of 1943. 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.

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. 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. 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 over 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. 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.

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. 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 Sud'' with Art. Abt. 836,

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. An estimated 2,754 civilians were killed in London by V-2 attacks with another 6,523 injured, which is two people killed per V-2 rocket.

Countermeasures

Big Ben and Crossbow

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 at up to three times the speed of sound at sea level (approximately 3550 km/h). 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 led to 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 led to 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 having no obvious effect, and jamming efforts ended.Jeremy Stocker

Anti-aircraft gun system

General

Frederick Alfred Pile General Sir Frederick Alfred Pile, 2nd Baronet, (14 September 1884 – 14 November 1976) was a senior British Army officer who served in both World Wars. In the Second World War he was General Officer Commanding Anti-Aircraft Command, one ...

, 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, almost 90 tons of rounds, which would cause far more damage than the missile. At a 25 August 1944 meeting of the Crossbow Committee, the concept was rejected. 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 grids of the London area. After the trajectory was determined, the guns would aim and fire between 60 and 500 rounds. 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 carried out 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 the plan moved ahead, and 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 liberation of their launching areas. 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 turned their attention to Antwerp. Plans were made to move the Pile system to protect that city, but the war ended before anything could be done.

Direct attack and disinformation

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 through

. 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

). According to the BBC television presenter Raymond Baxter, who served with the RAF during the war, in February 1945 his squadron was carrying out a mission against a V2 launch site, when one missile was launched in front of them. One member of Baxter's squadron opened fire on it, without effect. 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.

Assessment

The German V-weapons (V-1 and V-2) cost the equivalent of around US$500 million. Given the relatively smaller size of the German economy, this represented an industrial effort on par 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 ( in 2011) each; 3,225 were launched.

, 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 mission over Holland saw a V-2 in flight on its way to strike London: "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." 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 supporters with their miracle weapon. The V-2 had no effect on the outcome of the war, but it led to the

to launch V-2 missiles against United States cities, though only with considerable effort (and limited effect). Hitler, in July 1944 and Speer, in January 1945, made speeches alluding to the scheme, though Germany did not possess the capability to fulfill these threats. These schemes were met by the Americans with Operation Teardrop. 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.

) to ensure they were not captured by the advancing Soviets or shot dead by the Nazis to prevent their capture. After the Nazi defeat, German engineers were moved to the United States, the United Kingdom and the USSR, where they further developed the V-2 rocket for military and civilian purposes. The V-2 rocket also laid the foundation for the liquid fuel missiles and space launchers used later.

In October 1945, '' 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 move 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. In 1946, the

, 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. In 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. A committee was formed with military and civilian scientists to review payload proposals for the reassembled V-2 rockets. This led to an eclectic array of experiments that flew on V-2s and paved the way for American manned space exploration. Devices were sent aloft to sample the air at all levels to determine

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 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 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

, the "chief designer" of the Soviet rocketry program. The first Soviet missile was the R-1, a duplicate of the V-2 completely manufactured in Soviet Union, which was first launched in October 1948. From 1947 until the end of 1950, the German team elaborated concepts and improvements for extended payload and range under 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 was focused on larger missiles, the R-2 and R-5, based on further developing the V-2 technology with using ideas of the German concept studies. Details of Soviet achievements were unknown to the German team and completely underestimated by Western intelligence until, in November 1957, the Sputnik 1 satellite was successfully launched to orbit by the Sputnik rocket based on R-7, the world's first intercontinental ballistic missile. In the autumn of 1945, the group led by M. Tikhonravov K. and N. G. Chernyshov at NII-4 rocket artillery institute of the USSR Academy of Sciences developed on their own initiative the first stratospheric rocket project. VR-190 called for vertical flight of two pilots to an altitude of 200 km using captured German V-2 rockets.
