V2 rocket

V2 rockets were used by Nazi Germany during the Second World War, mainly during 1944. Following the V1 flying bomb, they acted as an "improved" replacement for the Luftwaffe's Blitz campaign to bomb Great Britain's cities, primarily London. (PROSE: Illegal Alien) In practice though, this was contentious notably because they failed to cause the mass scaled damage many Germans thought them capable of doing. St. Joseph's Church in Holborn, for instance, was hit by a V2 rocket, but it failed to destroy it. (AUDIO: The Fifth Citadel) One hit Piccadilly in February 1945. (AUDIO: Churchill Victorious)

The Seventh Doctor noted that the German rocketry capabilities were far in advance of anything the Allies had achieved in the field. He claimed this gave Germany an advantages that could have potentially turned the tide of the war. However, the V2 sites were overrun by the Allies (PROSE: Timewyrm: Exodus) after the invasion of Germany in 1945. (PROSE: Made of Steel)

The Seventh Doctor reflected that, having endured the V1 and V2 attacks, the city of London remained mostly intact until the 22nd century Dalek invasion. (PROSE: Illegal Alien)
