The Dassault Mirage IIIO is a single-engine, single-seat, supersonic fighter first flown in 1956 and introduced in 1961. The Australian Mirage IIIO is an Australian-constructed variant of the Dassault Mirage IIIE, but with different avionics. The Government Aircraft Factory produced three types of Mirage IIIO; the Mirage IIIO(A) attack variant, the Mirage IIIO(F) interception variant, and the Mirage IIIO(D) two-seat trainer. Over time, the (F) variants were converted to the (A) in between 1967 and 1979.
The Mirage IIIO(A) is a relatively inexpensive multirole combat aircraft available to ANZAC and BLUFOR decks. It carries twin 30mm DEFA 550 cannons, six Mk 82 bombs, and a pair of AIM-9B Sidewinders to round off its weapon compliment. The Mirage IIIO(A) can be used to effectively attack lightly armored columns and infantry with its Mk 82 bombs, and can attack enemy helicopters operating in its vicinity with its AIM-9 and cannon compliment. The major drawbacks of the Mirage IIIO(A) are its lack of ECM, lack of a long range missile, and the poor performance of the AIM-9B. Because the aircraft carries no ECM, it is vulnerable to attacks by long range SAMs and AAMs. The AIM-9B is short ranged and not particularly maneuverable, and the Mirage IIIO(A) lacks the ability to engage enemy fighters at longer ranges. At 80 points per aircraft, however, the Mirage IIIO(A) provides the player with decent strike and point defense capabilities for a relatively low cost.
