The CAC Mustang is an Australian variant of the North American P-51 Mustang. It was built under license by Commonwealth Aircraft Corporation in the final stages of World War II, and though it was too late to see combat, it did participate in the Occupation of Japan after VJ-Day.

Design and development

Local assembly of the P-51D (CA-17; Mk 20)

In December 1942, the Australian War Cabinet began looking to acquire a fighter aircraft with greater range than the Supermarine Spitfire. As a result, arrangements were made in November 1943 for Commonwealth Aircraft Corporation to build 690 aircraft through kits supplied by North American Aviation (NAA). ^[2] Only the first 100 unassembled aircraft were delivered, and four reportedly had the "razorback" style canopy of the P-51B/C variant. 80 of the kits were assembled under the designation CA-17 Mustang Mk 20 with Packard V-1650-3 Merlin engines, the remainder being used for spare parts. ^{[2] [3] [4]} The end of the war led to most of the orders being cancelled.

Local manufacturing of the CA-18 Mustang (Mk 21–23)

In late 1946, CAC received a contract to build 170 (later reduced to 120) Mustangs locally from scratch. These aircraft carried the new designation CA-18.

• The first 40 were designated Mustang Mk 21 and powered by Packard V-1650-7 Merlins. 66 Mustang Mk 23s followed with British-built Rolls-Royce Merlin 66 or 70 engines.
• A total of 14 Mustang Mk 22 reconnaissance aircraft were built with F24 cameras, and a further 14 were converted from Mk 21s. ^[4]

Additional orders for the CA-18, as well as 250 aircraft designated CA-21, were canceled in favor of further, US-built P-51D and P-51K variants. ^[5]

Operational history

The first production CA-17 Mustang Mk 20, serial number A68-01 (not to be confused with the US-built prototype A68-1001), made its first flight on 29 April 1945 from Fishermans Bend. ^{[5] [6]} The aircraft was handed over to the RAAF on 4 June 1945 and was tested by the No. 1 Aircraft Performance Unit. Trials ended in October 1946, and the aircraft was placed in storage until 1953. ^[5] Only 17 CA-17s were delivered to the RAAF by VJ-Day. ^[2]

The first operational units to receive the CAC Mustang were No. 84 and No. 86 Squadron. ^[2] Additional squadrons equipped with Mustangs (both American and locally-built) were No. 3, No. 4, No. 76, No. 77, and No. 82 Squadron as well as No. 21, No. 22, No. 23, No. 24, and No. 25 Squadron of the Citizen Air Force. The RAAF replaced its last Mustangs with de Havilland Vampires in 1959, while the last Mustang-equipped Citizen Air Force squadron, No. 24, retained its Mustangs until the CAF was disbanded in 1960. ^[2]
