s was simple to build but relatively fuel inefficient. Design of the Porsche 005 began in late 1944 with the aim of providing a more fuel efficient engine for the V-1 allowing for greater ranges. The use of the Porsche 005 turbojet was projected to increase the range of the V-1 from to and allow launching without ramps. During the last months of World War II the Porsche 005 project was being led by Dr Max Adolf Mueller, who had worked on jet engine projects for both
