Developed from the Ikara anti-submarine missile, the Turana was intended to provide a parachute recoverable pilotless target for use in gunnery and missile defence training by the Royal Australian Navy (RAN). It was powered by a small gas turbine Microturbo 022-01 jet engine with a booster rocket for launch from a warship's Ikara missile launcher. Prototypes were built in the late 1960s by the Government Aircraft Factories (GAF). In 1971, the RAN ordered twelve Turana targets at a cost of $1.183 million from GAF despite the fact that trials had not yet been completed. Turana Technical Evaluation Trials were conducted by HMAS Swan (III) in February 1978. Failures exposed during this period involved redesign work costing an additional $3.40 million. The Turana project was subsequently cancelled by the federal government in September 1979. A later audit report criticised a lack of communication between the Navy and GAF during the initial design and redesign stages of the project.
