The English Electric Canberra is a British first-generation jet powered medium bomber. It was developed by English Electric during the mid-to-late 1940s in response to a 1944 Air Ministry requirement for a successor to the wartime de Havilland Mosquito fast bomber. Among the performance requirements for the type was an outstanding high-altitude bombing capability and high speed. These were partly accomplished by making use of newly developed jet propulsion technology. When the Canberra was introduced to service with the Royal Air Force (RAF), the type’s first operator, in May 1951, it became the service’s first jet-powered bomber.

In February 1951, a Canberra set another world record when it became the first jet aircraft to make a non-stop transatlantic flight. Throughout most of the 1950s, the Canberra could fly at a higher altitude than any other aircraft in the world and in 1957, a Canberra established a world altitude record of 70,310 feet (21,430 m). Due to its ability to evade the early jet interceptor aircraft and its significant performance advancement over contemporary piston-engined bombers,

Design

The English Electric Canberra is a bomber aircraft powered by two jet engines, and able to fly at high-altitudes. An early prototype operated by Rolls-Royce would regularly fly to 63,000 feet, where the usable speed range (coffin corner) was only 25 knots, during Avon engine test flights. The overall design has been described as being of a simple nature, somewhat resembling a scaled-up Gloster Meteor fighter, except for its use of a mid wing. The Canberra principally differed from its preceding piston-powered wartime bombers by its use of twin Rolls-Royce Avon turbojet engines.[ The fuselage was circular in cross section, tapered at both ends and, cockpit aside, entirely without protrusions; the line of the large, low-aspect ratio wings was broken only by the tubular engine nacelles.The Canberra had a two-man crew in a fighter-style cabin with a large blown canopy, but delays in the development of the intended automatic radar bombsight resulted in the addition of a bomb aimer’s position housed within the nose. The pilot and navigator were positioned in a tandem arrangement on Martin-Baker ejection seats.

The wing is of single-spar construction that passes through the aircraft’s fuselage. The wingspan and total length of the Canberra are almost identical at just under 65 ft (20 m).

The Canberra B.2 started to enter service with 101 Squadron in January 1951, with 101 Squadron being fully equipped by May, and a further squadron, No. 9 Squadron equipping by the end of the year. The production of the Canberra was accelerated as a result of the outbreak of the Korean War, orders for the aircraft increased and outpaced production capacity, as the aircraft was designated as a "super priority".
