The Argus As 014 was a pulsejet engine used on the German V-1 flying bomb of World War II, and the first model of pulsejet engine placed in mass production. License manufacture of the As 014 was carried out in Japan in the latter stages of World War II, as the Kawanishi Maru Ka10 for the Kawanishi Baika kamikaze jet.

The Republic-Ford JB-2, also known as the Thunderbug, KGW and LTV-N-2 Loon, was a United States copy of the German V-1 flying bomb. Developed in 1944, and planned to be used in the United States invasion of Japan, the JB-2 was never used in combat. It was the most successful of the United States Army Air Forces Jet Bomb (JB) projects during World War II. Postwar, the JB-2 played a significant role in the development of more advanced surface-to-surface tactical missile systems such as the MGM-1 Matador and later MGM-13 Mace.
