Aircraft technicians are providing integral maintenance support for four RAAF AP-3C Orion maritime patrol aircraft. They ensure the AP-3C Orion aircraft is safe to conduct the long-range surveillance missions within the southern search corridor. With the support of No. 10 Squadron, search and rescue operations are able to be conducted continuously throughout daylight hours. The Australian search area is located 1500 nautical miles to the west-southwest of Perth and takes in an area of over 175,000 square nautical miles of ocean. The international military contribution includes a Royal New Zealand Air Force (RNZAF) P-3K2 Orion aircraft, a United States (US) Navy P-8 Poseidon maritime patrol aircraft, two People's Liberation Air Force (PLAF) Ilyushin IL-76 and two Japanese Maritime Self Defence Force (JMSDF) P-3C Orion aircraft along with one P-3C Orion and C-130H from the Republic of Korea.
