The Douglas SBD Dauntless is a World War II American naval scout plane and dive bomber that was manufactured by Douglas Aircraft from 1940 through 1944. The SBD ("Scout Bomber Douglas") was the United States Navy's main carrier-based scout/dive bomber from mid-1940 through mid-1944.
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 July 1944 unofficial record of the Me 163B V18 was officially surpassed in November 1947, when Chuck Yeager flew the Bell X-1 to 1,434 km/h (891 mph). The official speed record for a seaplane moved by piston engine is 709.209 km/h (440.682 mph), which attained on 24 October 1934, by Francesco Agello in the Macchi-Castoldi M.C.72 seaplane ...
The Douglas XB-42 Mixmaster is an experimental American bomber aircraft, designed for a high top speed.The unconventional approach was to mount the two engines within the fuselage driving a pair of contra-rotating propellers mounted at the tail in a pusher configuration, leaving the wing and fuselage clean and free of drag-inducing protrusions.
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 B-26's relatively small wing area and resulting high wing loading required a high landing speed of 120 to 135 mph (193 to 217 km/h) indicated airspeed depending on load. At least two of the earliest B-26s suffered hard landings and damage to the main landing gear, engine mounts, propellers, and fuselage.
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.
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.
