[1][2][3] At the end of World War II, the design of the Porsche 005 turbojet had not been finalised and no parts had been constructed.
[3] The Argus As 014 pulsejet used in production V-1 flying bombs 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.
[3][4] Dr Mueller was taken into captivity at the end of the war, and later prepared a drawing of the Porsche 005 for American investigators.
[3] Note that only limited progress on the Porsche 005 design had been made by the end of World War II.
