The Boeing B-29 Superfortress was an American ten seat long-range strategic bomber/reconnaissance aircraft of the Second World War, first flown in 1942 with production ending in 1946 with some of the 3960 aircraft made being converted into flight refuelling tankers and others seeing service during the Korean War. The Boeing B-29 was powered by four 2200 hp Wright R-3350-23-23A/-41 Cyclone 18 turbocharged radial piston engines providing a top speed of 576 kmh and a range of 5230 km. Armaments consisted of two 0.5 inch machine-guns in each of four remotely-controlled power-operated turrets, and three 0.5 inch machine-guns or two 0.5 inch machine-guns and one 20 mm cannon in the tail turret, and a bomb load of up to 9072 kg. On the 9th of March 1945 334 Boeing B-29 bombers conducted a low-level night terror attack on Tokyo, Japan, dropping incendiary bombs which resulted in the deaths of some 80000 civilians and it was a Boeing B-29, the Enola Gay, that dropped the first atomic bomb on the 6th of August 1945 over Hiroshima in Japan, though even that attack didn't kill as many as the earlier fire-bombing of Tokyo.
