In 1942 Beech Aircraft had already started work on the design of a "bomber destroyer" aircraft, when the Army expressed an interest in developing a similar concept as a potent ground attack aircraft (as a replacement for the Douglas A-20 Havoc), to attack tanks, bunkers, and other hard-to-kill targets. The Beech design was already known as the Beech Model 28 and had been given the name "Destroyer". In December 1942 the Army awarded Beech a contract to build two prototypes, under the designation XA-38. The name was changed to "Grizzly" soon after construction was begun. The Grizzly packed a formidable punch, with a 75mm cannon (with 20 rounds of ammo) sticking out of it's stream-lined nose, as well as two nose-mounted .50 caliber machineguns, and a pair of .50s in each of the remotely controlled ventral and dorsal turrets. These turrets were controlled by a gunner using periscopic sights (similar to those used on the B-29) from the glassed-in observer's station in the aft fuselage. First flight of the initial prototype took place on May 7, 1944. Performance tests by the Army Air Corps were held through 1944 and 1945, with the results being as good or better than expected in most respects, including speed. There is even a story that the Grizzly "ran away" from a P-51B Mustang that was being used as a chase plane. Gunnery tests proved the effectiveness of the heavy armament, and serviceability was praised as well. Had the war continued it is probable that - with its speed, firepower, and rugged construction - the A-38 would have become the Army Air Force's most important attack bomber. However, by this time it was 1945, and it was becoming obvious that, not only was the war coming to an end, but so was the day of the piston engine. In addition to this, the engines for the Grizzly were the same as those used in the B-29, and the few engines that were not slated for that bomber were usually given to the new Douglas BT2D-1 and Martin Mauler aircraft programs. The program ended with only the two prototypes being built, with one being scrapped in the forties, and the other being slated for display in the Air Force Museum, but disappearing, never to be seen again. The Grizzly remains a minor footnote in U.S. aviation history, as well as one of the most tantalizing "might-have-beens" of the war.

I'm surprised no one picked up on this, esp Herr Rommel!!

Same engines as a B-29. Wow, no wonder it was fast!

Good thought. The problem is with the 75mm cannon. EAW has the guns hard-coded, and allows only 4 types (light MG, heavy MG, 20mm cannon, 30mm cannon). By tweaking the dispersion rating, and rate of fire I managed to simulate the 37mm cannon for the Ju87G, and (far less convincingly) the 57mm for the Mosquito XVIII. The 75mm is just so much bigger and heavier than the 30mm that it is not reasonably possible to simulate, in my view. If you want a heavy-duty ground-attack aircraft, though, try the A26 Invader with its 14 0.50 cal MGs.
