North American B-25 Mitchell Low-poly 3D model

The North American B-25 Mitchell is an American medium bomber that was introduced in 1941 and named in honor of Major General William Billy Mitchell, a pioneer of U.S. military aviation. Used by many Allied air forces, the B-25 served in every theater of World War II, and after the war ended, many remained in service, operating across four decades. Produced in numerous variants, nearly 10,000 B-25s were built. These included several limited models such as the F-10 reconnaissance aircraft, the AT-24 crew trainers, and the United States Marine Corps' PBJ-1 patrol bomber. In anti-shipping operations, the USAAF had an urgent need for hard-hitting aircraft, and North American responded with the B-25G. In this series, the transparent nose and bombardier/navigator position was changed for a shorter, hatched nose with two fixed .50 in (12.7 mm) machine guns and a manually loaded 75 mm (2.95 in) M4 cannon,[14] one of the largest weapons fitted to an aircraft, similar to the British 57 mm gun-armed Mosquito Mk. XVIII and the autoloading German 75 mm long-barrel Bordkanone BK 7,5 heavy-calibre ordnance fitted to both the Henschel Hs 129B-3 and Junkers Ju 88P-1. The B-25G's shorter nose placed the cannon breech behind the pilot, where it could be manually loaded and serviced by the navigator; his crew station was moved to a position just behind the pilot. The navigator signaled the pilot when the gun was ready and the pilot fired the weapon using a button on his control wheel.
