The Aussies have made the first formal decision to participate in the P-8/MMA program to replace their AP-3 Orions. Interestingly, like the US Navy, they will augment their MPRA (Maritime Patrol and Response Aircraft) with a Multi-mission Unmanned Aerial System but they did not make a decision to participate in the Navy Broad Area Maritime Surveillance (BAMS) Unmanned Aerial Vehicle.
