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 genesis of the DB-3 lay in the BB-2, Sergey Ilyushin's failed competitor to the Tupolev SB.Ilyushin was able to salvage the work and time invested in the BB-2's design by recasting it as a long-range bomber, again competing against a Tupolev design, the DB-2, to meet the stringent requirements of an aircraft capable of delivering a 1,000 kg (2,200 lb) bombload to a range of 3,000 km (1,900 ...
The Ki-15 was designed by the Mitsubishi corporation to meet an Imperial Japanese Army Air Force requirement of 1935 for a two-seat, high-speed reconnaissance aircraft. [1] The resulting aircraft was a low-wing cantilever monoplane with a fixed, spatted undercarriage, similar to other all-metal stressed-skin monoplanes developed elsewhere in ...
The B Mk.XVI had a maximum speed of 408 mph (657 km/h), an economical cruise speed of 295 mph (475 km/h) at 20,000 ft, and 350 mph (560 km/h) at 30,000 ft, [154] ceiling of 37,000 ft (11,000 m), a range of 1,485 nmi (2,750 km), and a climb rate of 2,800 ft per minute (14 m/s). The type could carry 4,000 lb (1,800 kg) of bombs.
The first aircraft adopted for the Schnellbomber role was the single-engine Heinkel He 70, but it soon was replaced by the twin-engine Dornier Do 17 in that role. In the 1937 air races in Switzerland the Do 17 won a number of speed records, apparently demonstrating the value of the concept.
The Northrop B-2 Spirit, also known as the Stealth Bomber, [3] is an American heavy strategic bomber, featuring low-observable stealth technology designed to penetrate dense anti-aircraft defenses. A subsonic flying wing with a crew of two, the plane was designed by Northrop (later Northrop Grumman ) as the prime contractor, with Boeing ...
In February 1943 the Imperial Navy staff asked Nakajima Aircraft Company to design a four-engined bomber, capable of meeting an earlier specification set for a long-range land-based attack plane. The final specification, issued on 14 September 1943, called for a plane with a maximum speed of 320 knots (590 km/h; 370 mph) able to carry a 4,000 ...
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 ...
