The Beechcraft XA-38 Grizzly was a United States ground attack aircraft, fitted with a forward-firing 75 mm cannon to attack heavily armored targets. The first prototype flew on 7 May 1944 but after testing it became obvious it would not be ready for the projected invasion of Japan, and furthermore it used engines required by the B-29 Superfortress — which had priority - and so it was canceled after two prototypes had been completed.

Design and developmentEdit

The United States Army Air Forces awarded the Beech Aircraft Corporation a contract in December 1942 for two prototypes for their Model 28 "Destroyer". The requirement was for a powerful ground attack aircraft to replace the Douglas A-20 Havoc, with the ability to hit "hardened" targets like tanks and bunkers. This capability was achieved through a 75 mm cannon with 20 rounds, mounted in a fixed position on the nose as well as two .50 cal (12.7 mm) M2 Browning machine guns firing forward. Defensive armament consisted of remotely-controlled ventral and dorsal turrets, each armed with twin .50 cal (12.7 mm) machine guns. There were to be two crew members, a pilot and an observer/gunner in the rear cabin, using periscope sights to aim the guns.


On 7 May 1944, Beech test pilot Vern Carstens flew the XA-38 on its maiden flight from the company's Wichita airfield. The aircraft proved satisfactory in all respects and better than expected in some, including top speed. During testing, the XA-38 prototypes were flown by U.S. Army pilots and serviced by military personnel, proving to be reliable and establishing a high level of serviceability.[1] The armament proved especially effective and had it not been for wartime priorities shifting in 1944, the aircraft would most likely have been ordered in quantity[citation needed], although the B-29 had priority for the Wright R-3350 engines. Instead, one prototype was scrapped and the other, intended for the USAF Museum, had an unknown fate.
