History

The Aggregate 3 (A-3) was the third in a series of ballistic missiles designed and developed by Dr.-Ing. Wernher von Braun in 1937 under the leadership of Dr. Walter Robert Dornberger, at Kummersdorf south of Berlin.

The Aggregate 3 (A-3) ballistic missile was 6.74 m long by 0.68 m in diameter and had a takeoff weight 748 kg. The A-3 also incorporated a three gyroscope system to control the missile during flight, the missile also had a parachute installed to facilitate recovery. The rocket engine used in the Aggregate 1 (A-1) and Aggregate 2 (A-2) was also used in the Aggregate 3 (A-3) with some minor modifications, which was a pressure fed system using 25% liquid oxygen and 75% ethanol, to give a maximum thrust of 1,500 kg for 45 seconds of burn time, which was designed by Arthur Rudolph.

There were numerous tests flights of the Aggregate 3 (A-3) many ending in failures however the first launching took place on 4 December 1937, another launch took place on 11 December 1937. The testing of the Aggregate 3 (A-3) took place at Kummersdorf under the watchful eye of Werner von Fritsch, and at Greifswalder Oie, Peenemünde. Development of the Aggregate 3 (A-3) was abandoned in favour of the Aggregate 5 (A-5) which was a scaled-down version of the Aggregate 4 (A-4).
