The development of an US. recoilless rifle started in 1940, when Germany put weapons of this type into action. In the end of 1943 two calibres emerged, 57mm and 75mm. After some live fire exercises in September 1944 at the Aberdeen Proving Ground, an order of 1000 weapons of each type were placed. ~100 Kcls reach the European battlefields in mid March 1945 - just before the German surrender. Instead the weapon proved it self on the Okinawan and Iwo-Jima campaigns.
