The Storm of War - Andrew Roberts [292]
The huge ground-space that the V-1 could devastate – a single flying bomb might damage an area covering a quarter of a square mile – made it a particularly dangerous weapon, although the defenders quickly adapted. Between June and September 1944, for example, 3,912 were brought down by anti-aircraft fire, RAF fighters and barrage balloons. It soon became clear that Hitler, who had hoped that V-1s might destroy British morale and force the Government to sue for peace, was wrong about the weapon’s potential. He therefore placed hopes in the V-2, which had been devised at the Peenemünde research centre in Pomerania and which comprised ground-breaking rocket technology. It was a supersonic ballistic missile, flying faster than the speed of sound, so the first thing its victims heard was the detonation. No air-raid sirens could be sounded or warnings given, which added to the terror, and there was no possibility of interception because it flew at 3,600mph, ten times faster than the Spitfire.
The gyroscopically stabilized fin guided this huge, 13-ton machine for distances of up to 220 miles. It was originally intended to be loaded with poison gas, and only had its 1-ton high-explosive warhead attached later. Its astonishing speed came from a mixture of alcohol and liquid oxygen being pumped into the motor by two centrifugal pumps driven by turbines and heated to 2,700 Celsius. It could fly at a maximum height of 100,000 feet. The V-2 was enormous: 46 feet high, with a diameter of over 5 feet in the middle, and 12 feet down by the fins, it was by far the biggest weapon of its kind. Launched from an upright position from vehicles that simply drove off after firing, it did not even have launch-pad installations – as most V-1s needed – that the Allies could bomb and overrun. (Both V-weapons can be seen today at the Imperial War Museum in Lambeth, London.)
With production at full capacity in the autumn of 1944, Hitler hoped that London could be bombed into submission before the Allies could reach Germany and destroy the Third Reich. Yet it was largely his own fault that the V-2 came on stream so late. If he had given high priority to it in 1942, its teething problems might have been sorted out in time to mass-produce it in 1943 rather than 1944.59 Of course increased rocket production would have had to take the place of some other weapon programmes, be they for warplanes, tanks or submarines. There were a high proportion of misfires,
