The V1and V2 were used for a ballistic missile. 

The V2 was a liquid fuel rocket missile had more range than the V1. There was no way to stop or detect this missile. The V2 was based off of Warner Von Braun's design and both the V1 and V2 (were made by concentration camp slaves). The V2 was actually used after the war when Germany was falling they decided to bomb the cities. There was more than one V1 and V2. There were many, they were called the v-weapons. They bombed many places like London and Antwerp and many others but Antwerp was the worst area of the v-weapon campaign. Cities around the area were hit the most and worst.
