Development
In 1951, CAC obtained a licence agreement to build the F-86. It was decided to power the aircraft using a licence-built version of the Rolls-Royce Avon R.A.7. This involved a re-design of the fuselage as the Avon was shorter, wider and lighter than the General Electric J47 that powered the North American-built aircraft. Because of the engine change the type is often referred to as the Avon Sabre. To accommodate the Avon, over 60% of the fuselage was redesigned along with a 25% increase in the size of the air intake. Another major revision was in replacing the F-86F's six machine guns with two 30mm Aden cannons, while other changes were also made to the cockpit and to provide an increased fuel capacity.
The prototype aircraft (designated CA-26 Sabre) first flew on 3 August 1953. The production aircraft were designated the CA-27 Sabre and first deliveries to the Royal Australian Air Force began in 1954. The first batch of aircraft were powered by the Avon 20 engine and were designated the Sabre Mk 30. Between 1957 and 1958 this batch had the wing slats removed and were redesignated Sabre Mk 31. These Sabres were supplemented by 20 new-build aircraft. The last batch of aircraft were designated Sabre Mk 32 and used the Avon 26 engine.

Famous quotes containing the word development:
“John B. Watson, the most influential child-rearing expert [of the 1920s], warned that doting mothers could retard the development of children,... Demonstrations of affection were therefore limited. “If you must, kiss them once on the forehead when they say goodnight. Shake hands with them in the morning.””
—Sylvia Ann Hewitt (20th century)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“... work is only part of a man’s life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877–?)
