ENGLISH ELECTRIC
CANBERRA

Originally known as the English Electric A.1 the Canberra was renamed by the Company's chairman, Sir George Nelson, as Australia was the first export customer for the aircraft.

The Canberra was modelled on the same design brief as the de Havilland Mosquito i.e. to provide maximum bomb load, fitting of two very powerful engines and with the most effective aerodynamic package possible.

The Canberra was mainly a metal aircraft with only the forward portion of the fin being of wooden construction. The fuselague was a semi-monocoque design with a pressurised nose compartment with the crew each having a Martin-Baker ejector seat.

There were two bomb bays in the fuselage protected by conventional bomb bay doors. The wings were of a single spoar construction which passed straight through the fuselage from one side to the other with control surfaces operated by conventional means.

The Canberra was powered by two Rolls Royce Avon turbojets producing 7,400 lbf of thrust each.
Early Canberras had a glazed nose to carry a bomb aimer due to delays in the intended radar bombsight.

Many conventional weapons could be carried by the Canberra such as: 250lb, 500lb, and 1000lb bombs with a total bomb load of up to 10,000lb.

The undercarriage of the Canberra was manufactured from an new alloy (DTD683) which was prone to stress corrosion causing them to decay in a few years. To avoid the hazard of undercarriage failure regular inspections were carried out initially using Radiographic techniques and then later a more reliable Ultrasound inspection.

The Canberra B2 entered service with RAF No.101 Squadron in January of 1951 and No.9 Squadron by the end of that year.

As a result of the Korean War manufacture of the Canberra was stepped up and a further Squadrons were issued with the aircraft by the end of 1952.

Bomber Command retired the last Canberra on the 11th of September 1961, however, overseas Squadrons in Germany, Cyprus and Singapore continued to use the aircraft in the nuclear strike role.

The Cyprus based Squadrons were made unoperational in 1969 with the Singapore based quadrons following suit in 1970. The last of the German based Squadrons disbanded in 1972 and were the last Canberra bombers in RAF service.

The RAF continued with the Canberra in service after 1972 in a reconnaissance role with many variants being produced during this time. The PR9 remained in service with RAF No.39 Squadron until July of 2006 in the reconnaissance and photograhic maping role.

The last sortie of a Canberra took place on the 28th of July 2006 to commemorate the standing down of RAF No.39 Squadron at RAF Marham by a flypast.

The Canberra was the first jet powered light bomber during the 1950's to be built in large numbers.

It was capable of flying at high altitude and set a World record at the time of 70,310ft.

Due to its superior performance over piston engines of the day, the Canberra was in demand overseas and served with many nations.
