Heading to retirement of the AP-3C after 50 years of service

The Air Force began the draw down of the  AP-3C Orion following the arrival of the P-8A Poseidon, after serving as Australia's primary Maritime Patrol aircraft. Initially P-3 patrols involved the regular monitoring of Soviet ship and submarine movements in South East Asia, however it soon involved the use of radar and sonar buoys to actively detect, identify and track submarines. After the Cold War, the P-3 patrols continued as new demands arose to stop piracy, smuggling and terrorists.
