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 ...
The second prototype's top speed of 423 km/h (263 mph) at 4,000 m (13,130 ft) led the Imperial Japanese Army Air Force to place an order for 16 service trials machines. These were delivered in January 1938 and after successful trials the Army ordered the Ki-30 into production in March under the designation Army Type 97 Light bomber. [4]
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 ...
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).
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.
