The P1Y was designed by the Yokosuka Naval Air Technical Arsenal to Navy specification 15-Shi, [2], calling for a fast bomber with speed matching the Zero, range matching the G4M, a 907 kg (2,000 lb) bombload, and the ability to dive-bomb as well as carry torpedoes. As the result, the construction suffered from excess complexity, difficulty of ...
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 ...
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 USAAF B-25B Mitchell, a medium bomber. Polish PZL.37 Łoś, a medium bomber. The Japanese Mitsubishi G4M "Betty", a medium bomber.. A medium bomber is a military bomber aircraft designed to operate with medium-sized bombloads over medium range distances; the name serves to distinguish this type from larger heavy bombers and smaller light bombers.
The possibilities of exchanging some of the fuel of the ANT-25 for bombs and/or cameras was recognized early in its development, and the Soviet Air Forces (VVS) issued a requirement for an aircraft to carry 1,000 kg (2,200 lb) over an operational radius of 2,000 km (1,200 mi) at a speed of 200 km/h (120 mph).
In the early morning of 3 August 1935, Levanevsky, Baydukov and Levchenko climbed aboard their RD and took to the air. For the first 50 kilometres (31 mi), the aircraft ascended to only 500 metres (1,600 ft). They then steadily increased their altitude to 5,000 metres (16,000 ft), maintaining an average speed of 165 kilometres per hour (103 mph).
Unlike the B-1A, the B-1B cannot reach Mach 2+ speeds; its maximum speed is Mach 1.25 (about 950 mph or 1,530 km/h at altitude), [77] but its low-level speed increased to Mach 0.92 (700 mph, 1,130 km/h). [64] The speed of the current version of the aircraft is limited by the need to avoid damage to its structure and air intakes.
The G4M's predecessor, the Mitsubishi G3M, went into service in 1937 in China. [5] Only two months later the Japanese Navy issued specifications to Mitsubishi. [5] The specifications, unprecedented at the time, called for a twin-engine, land-based, attack bomber with a top speed of 398 kilometres per hour (247 mph), a cruising altitude of 3,000 metres (9,800 ft), and a range of 4,722 ...
