faster than any other piston-twin of World War II with a top speed of some 765 km/h (475 mph). The Bomber B high-speed medium bomber design competition for the Luftwaffe started in July 1939 was meant to create an updated design to take over the original Schnellbomber role by later in World War II, and function with a heavier bombload than the earlier Schnellbomber designs were capable of carrying, but due to the intractable development problems plaguing them, the continued unavailability of the needed pair of high power output engines of 1,500 kW (2,000 hp) and above each - primarily the complex, 24-cylinder multibank Junkers Jumo 222 - needed for such designs, no production aircraft were ever ordered under the Bomber B program. de Havilland Mosquito The most successful Schnellbomber of the war was the bomber version of the British de Havilland Mosquito. It retained a speed advantage over its enemies for much of the war, and was only able to be effectively countered by specialist versions of various night fighter designs, with the pioneering Me 262A jet fighter being a true potential threat in 1944. The Mosquito ended the war with the lowest loss rate among any aircraft in RAF Bomber Command. The Germans considered the Mosquito a superior implementation of their own Schnellbomber concept, and being a potential inspiration for the Focke-Wulf firm's own all-wood twin-engined, high-speed fighter design, the Focke-Wulf Ta 154 being given the name Moskito.
