You dont need a catapult for a gyro even non jump gyros can probably take off from the quarterdeck of a stationary cruiser. Australia will use mostly small disposable gyros as a cheap ASW and Artillery Spotting plataform. Gyro-glyders will be used aboard small escorts, while merchants might get larger full size gyros. However these are just plans. But I think Autogyros have a lot of untapped potential.
