The Acting Prime Minister announced the achievement of Initial Operational Capability (IOC) for the MQ-4C Triton and MC-55A Peregrine, the completion of major upgrades to the first two P-8A Poseidon aircraft in Australia's fleet in the United States, and the forthcoming commencement of upgrades to the remaining fleet at the recently opened Deep Maintenance and Modification Facility at RAAF Base Edinburgh. These milestones represent a significant enhancement to the Royal Australian Air Force's ability to deliver persistent intelligence, surveillance and reconnaissance effects across Australia's primary area of military interest. RAAF Base Edinburgh is the Royal Australian Air Force's principal Air ISR hub and home to No. 92 Wing, which operates the P-8A Poseidon, MQ-4C Triton and MC-55A Peregrine through Nos. 9, 10, 11, 12 and 292 Squadrons. Built through years of collaboration between Defence, industry and the United States, Australias integrated Air ISR fleet continues to grow.
