Site for German rocket motor technology of the Second World War,
principally focusing on the development of motors for aircraft and missiles
by Hellmuth Walter Werke of Kiel.

Based around detailed research into the Messerschmitt Me.163 "Komet" HWK 109-509 Liquid Bi-Fuel Rocket Motor,
this site is also a resource for other Walter rocket motors, their design and operational uses.
Walterwerke developed a wide range of rocket motors, some reliable, some experimental and some at the cutting edge of science and technology.
Here, you can find out about the design of the motor for the Me.163, about Walter take-off assisters,
motors for guided missiles and many other things.
