Three JMSDF P-3C Orions flying in formation during 2011

The Japan Maritime Self-Defense Force (JMSDF) has a large aviation component. As of 2012, it was equipped with over 200 fixed-wing aircraft and 150 helicopters. These aircraft operate from bases throughout Japan, as well as from the JMSDF's ships.[1]

History[]

The JMSDF's first aircraft were 16 Lockheed P2V Neptune – redesignated P-2 Neptune in the United States in September 1962 – maritime patrol aircraft, which were provided to the force by the United States Navy in 1956. The US Navy also provided Japan with 60 Grumman S-2 Trackers from 1957.[2] During the 1980s, the JMSDFs force of 82 Neptunes (most of which were the locally built Kawasaki P-2J variant) was replaced by about 100 Lockheed P-3 Orions.[3] The JMSDF's first combat helicopters were the Mitsubishi HSS-2 (the Japanese variant of the Sikorsky SH-3 Sea King).[4] These helicopters were replaced by SH-60Js during the 1990s.[5]

The JMSDF is the only force to operate minesweeping helicopters other than the US Navy. The first helicopters used for this purpose were eight V-107As.[6] These helicopters were replaced by eleven MH-53Es during the 1990s. Seven MCH-101 helicopters have been ordered to replace the MH-53Es, of which five had been delivered by mid-2012.[7]
