The Aggregate 5 (A-5) which was a ballistic missile, That was the forerunner for the Aggregate 4 (A-4) which was designed and developed by Dr.-Ing. Wernher von Braun in 1938 under the leadership of Dr. Walter Robert Dornberger, at Greifswalder Oie, Peenemünde.

The Aggregate 5 (A-5) ballistic missile was 6.85 m long by 0.67 m in diameter and had a takeoff weight 900 kg. The A-5 also incorporated the new Siemens control equipment 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), Aggregate 2 (A-2) and Aggregate 3 (A-3) was also used in the Aggregate 5 (A-5) 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 was also another variant of engine used to power the Aggregate (A-5) which used monopropellants that was mainly used for air testing with the He 111.

The control of the Aggregate 5 (A-5) was achieved by the gyroscopes, that basically act as an autopilot, and if necessary sending signals to the servos that were attached to the exhaust vanes, that would allow the missile to be returned the desired trajectory, the same applied if the missile was affected by gusts of wind. The autopilot would engage and change the trajectory.

After extensive wind tunnel tests conducted by Dr. Rudolph Hermann the missile was aerodynamically refined. And several flight tests were carried out using the He 111 as a carrier aircraft for the Aggregate 5 (A-5) in which the missile managed to exceed the speed of sound.

In 1938 Dr.-Ing. Wernher von Braun was ready to begin test launching of the Aggregate 5 (A-5) all the tests carried out attained astounding results for new Siemens control equipment functioned perfectly. Even the parachute opened when they should, and so all the groundwork had been done for the Aggregate 4 (A-4).
