The FM-2 Wildcat wound up being created and prototyped by Grumman Aircraft. A lot more than 4000 had been built by the Eastern Aircraft Division regarding the General Motors business between 1943 - 1945. These aircraft included a lighter airframe and a far more effective engine. This suggested there was clearly a physical design difference between the F4F whilst the FM-2. The FM-2 had a taller straight end for security to counter the increased torque associated with engine. Armament contained 4 - .50 cal. weapons, 2 - outside bomb or gas racks and atmosphere to ground rocket launch points on wings. These aircraft had been primarily operated from escort providers to steer ground operations in to the Pacific cinema of operations. These exact same aircraft was in fact teamed with Grumman Avengers and found in anti-sub operations inside Atlantic against U-boats.
