Further requirements included a top speed of 250 knots (460 km/h; 290 mph), a cruising speed of 200 knots (370 km/h; 230 mph) and a range of 1,000 nmi (1,900 km; 1,200 mi) with an 800 kg (1,800 lb) bomb load or 2,072 nmi (3,837 km; 2,384 mi) without external armament.
The Nakajima G10N Fugaku (Japanese: 富岳 or 富嶽, "Mount Fuji") was a planned Japanese ultra-long-range heavy bomber designed during World War II.It was conceived as a method for mounting aerial attacks from Japan against industrial targets along the west coast (e.g., San Francisco) and in the Midwest (e.g., Detroit, Milwaukee, Chicago, and Wichita) and the northeast (e.g., New York City ...
The first prototype flew in January 1937 and was ordered into production soon afterwards with the full designation Type 97 Carrier Attack Bomber [4] (九七式艦上攻撃機) (kyū-nana-shiki kanjō kōgeki-ki or kankō for short). [5] Combat experience during the Second Sino-Japanese War revealed several weaknesses in the original B5N1 ...
Thus, in the spring of 1942 an up-engined version was produced, fitted with more powerful Ha-109 engines and this became the production Army Type 100 Heavy Bomber Model 2 or Ki-49-IIa. The Model 2 also introduced improved armor and self-sealing fuel tanks and was followed by the Ki-49-IIb in which 12.7 mm (0.5 in) Ho-103 machine guns replaced ...
The Lockheed XB-30 (company model L-249) [1] was the design submitted by Lockheed after the request by the United States Army Air Forces for a very heavy bomber, the same request that led to the Boeing B-29 Superfortress, the Douglas XB-31 and Consolidated B-32 Dominator.
The XB-15 was not fast for a bomber but it was the fastest aircraft that could carry so much weight, and for such distances. In July 1939, Haynes received certificates from the NAA for an international 5,000 km (3,100 mi) speed record with a 2,000 kg (4,400 lb) payload.
where is propulsive efficiency (typically 0.65 for wooden propellers, 0.75 metal fixed pitch and up to 0.85 for constant-speed propellers), hp is the engine's shaft horsepower, and is true airspeed in feet per second, weight is in lbs.
Kawasaki Ki-48 after Japanese surrender. The aircraft served in China from late 1940, replacing the Kawasaki Ki-32, and were widely used in the Philippines, Malaya, Burma, New Guinea, the Solomon Islands and the Dutch East Indies, where the Ki-48 Ia and Ib models, slow and badly armed, were supplemented by the marginally improved Ki-48 IIa and IIc, which were maintained in service along with ...
