Senator PAYNE (New South Wales—Minister for Defence) (14:23): I thank Senator Whish-Wilson for his interest in the acquisition of the MQ-4C Triton, which will, of course, provide the Air Force with a high-altitude, long-endurance, remotely-piloted aircraft system which is optimised for use in maritime intelligence, surveillance and reconnaissance. It is designed to operate either alone or in conjunction with the P-8A Poseidon. I note the senator's reference to the defence white paper. The government's indication today is the commencement of the acquisition program for the MQ-4C Triton. We have indicated that our intention is to purchase six, with an option to look at a seventh. The PRESIDENT: Senator Whish-Wilson, a supplementary question.
