In 1951, CAC obtained a licence agreement to build the F-86F Sabre, in response to the cancelled CAC CA-23 project, 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, which was planned to be also used in the CAC CA-23 previously, 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.[1] 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's six machine guns with two 30mm ADEN cannon,[2] while other changes were also made to the cockpit and to provide an increased fuel capacity.[3]
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.[1] 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, of which 69 were built up to 1961.[2]
Operational history
A94-901 (Mk 30), the first production CAC Sabre, in the colours of the "Black Panthers" aerobatics team of No. 76 SquadronA94-964 and A94-982 (Mk 32), Thailand, c. 1962
From 1958 to 1960, CAC Sabres of No. 78 Wing RAAF (78 Wing), comprising 3 Sqn and 77 Sqn, undertook several ground attack sorties against communist insurgents in the Federation of Malaya, during the Malayan Emergency. Following the Emergency, they remained in Malaysia at RMAF Butterworth (RAAF Butterworth).[4] Armed with Sidewinder missiles, the Sabres were responsible for regional air defence during the Konfrontasi between Indonesia and Malaysia from 1963 until 1966, though no combat took place.[5] Between October and December 1965, a detachment of six Sabres, initially from 77 Sqn and later from 3 Sqn, was based at Labuan to conduct combat patrols over the Indonesian–Malaysian border on Borneo.[6]
In 1962, a detachment of eight CAC Sabres, which was later expanded and designated No. 79 Squadron RAAF (79 Sqn), was sent from RMAF Butterworth to Ubon Royal Thai Air Force Base (RAAF Ubon), Thailand, to assist the Thai and Laotian governments in actions against communist insurgents. Australia and Thailand were allies of South Vietnam and the United States during the Vietnam War; 79 Sqn was responsible for local air defence at Ubon, where United States Air Force attack and bomber aircraft were based. The squadron never engaged North Vietnamese aircraft or ground forces.[7][8] Two Sabres were lost to engine failure in Thailand, in September 1964 and January 1968. 79 Sqn ceased operations and was deactivated in July 1968.[9]
Former RAAF CAC Sabres were operated by 11 Squadron Royal Malaysian Air Force (11 Sqn RMAF) between 1969 and 1972. Following the establishment of better relations with Indonesia, 23 CAC Sabres were donated to the Indonesian Air Force (TNI-AU) between 1973 and 1975, and operated by No. 14 Squadron TNI-AU; five of these were former Malaysian aircraft.[2]
In Australia, there are only two former RAAF-owned Sabres (A94-983 and A94-352) that have been restored to flying condition, A94-983 is at the Temora Aviation Museum, New South Wales – ownership was transferred to the RAAF in July 2019 and it is operated by the Air Force Heritage Squadron (Temora Historic Flight).[12][13] A94-352 is currently owned privately by Sqn Ldr Jeff Trappett (RAAF retired) and is stored at Latrobe Regional Airport.[14] (A94-907 is also at Latrobe Valley being used as a source of parts in the restoration of A94-352.)
In 1973 A94-352 crashed on takeoff at Ngurah Rai International Airport, Bali, on its delivery flight to the Indonesian Air Force. The engine was removed and returned to CAC for assessment. On 18 February 1974 a submission was made and approval given on 14 March 1975 for free transfer of some spare parts to the Warbirds Aviation Museum.
Specifications (Mk 32)
Data fromMeteor, Sabre and Mirage in Australian Service[15]
Bombs: 5,300 lb (2,400 kg) of payload on four external hardpoints; bombs were usually only mounted on the inner two pylons, as the outer pair of pylons were wet-plumbed for 2× 200 imperial gallons (910 L) drop tanks to give the CAC Sabre a useful range. A wide variety of bombs could be carried with maximum standard loadout being 2 x 1,000 lb (450 kg) bombs plus 2 drop tanks. As an air superiority fighter, however, the air-to-ground mission loadout was not typically employed.
