English Electric Canberra pr9 Military Aircraft
The English Electric Canberra pr9 first flew on 8 July 1955 and was a conversion of the Canberra B1 bomber design for Photo-reconnaissance and tactical reconnaissance use fitted with seven cameras, the fuselage was stretched to 68 ft (27.72 m) and was fitted with twin 11,250 lbf (51.03 kN) thrust Avon 208 turbojets, each wing was increased by 2ft, the increased power and wing area allowed an increased operational ceiling in excess of 60,000ft where when it was conceived, it would be beyond possible fighter interception, like the American Lockheed U-2 spy plane.
The Canberra pr9 was fitted with an off-set fighter cockpit and required the navigator to sit in a forward facing ejection seat in the Canberra pr9's hinged nose, this gave the pilot improved visibility but left the navigator "in the dark" and in a rather claustrophobic position compared to earlier pr Canberras. A total of twenty Three Canberra pr9's were built by Short Brothers at Belfast for English Electric between 1958 and 1962, half of these were still operational with the RAF until June 2006.
