The V-2 rocket () was the world's first ballistic missile and first human object to fly in space. All modern rockets are based on the V2 design. The first successful launch was from Peenemünde on 3 October, 1942, reaching a height of 192 km. The V2 was designed by Nazis to bomb London, Antwerp and other European cities. It travelled at four times the speed of sound so was impossible to shoot down. The first V-2 used as a weapon exploded in Paris on 8 September 1944, with a second rocket exploding in London later that day. Over 3,000 V-2s were used by the German Wehrmacht against Allied targets in World War II, resulting in the death of an estimated 7,250 military personnel and civilians.
