From the Planes You’ve (Probably) Never Heard Of Department of Planelopnik, we bring you the Beechcraft XA-38 Grizzly.
The Fairchild Republic A-10 isn’t the only attack aircraft built around a gun. The XA-38 was intended as a replacement for the Douglas A-20 Havoc, and was built around a forward-firing 75mm cannon for attacking armored or hardened ground targets. It also sported six .50 caliber Browning M2 machine guns, two forward-facing, and two each in powered, remote controlled dorsal and ventral turrets. Unfortunately for the Grizzly, it was powered by the same engines used in the B-29, making it a low priority at the time, and when it became clear that the Grizzly wouldn’t be ready for the projected invasion of the Japanese homeland, the program was canceled after only two aircraft were produced.
