The F-86F was redesigned and built by the Commonwealth Aircraft Corporation (CAC). Equipping five RAAF squadrons, the type saw action in the Malayan Emergency in the late 1950s, and was employed for air defence in Malaysia and Thailand in the 1960s. Ex-RAAF models also saw service with the Royal Malaysian Air Force and the Indonesian Air Force. \u00a0 \nIn 1951, CAC obtained a licence agreement to build the F-86F Sabre. In a major departure from the North American blueprint, it was decided that the CA-27 would be powered by a licence-built version of the Rolls-Royce Avon R.A.7, rather than the General Electric J47. In theory, the Avon was capable of more than double the maximum thrust and double the thrust-to-weight ratio of the US engine. This necessitated a re-design of the fuselage, as the Avon was shorter, wider and lighter than the J47. Because of the engine change the type is sometimes referred to as the Avon Sabre. To accommodate the Avon, over 60 percent of the fuselage was altered and there was a 25 percent increase in the size of the air intake. Another major revision was in replacing the F-86F\u0027s six machine guns with two 30mm ADEN cannon, while other changes were also made to the cockpit and to provide an increased fuel capacity. \u00a0 \nFor details of the development and operational history of the CA--27 Sabre, click here.
