The Lockheed SP-2H Neptune was a maritime patrol and anti-submarine aircraft designed and manufactured in the United States. They were very popular and used by many Western air forces including Australia.

The Lockheed Neptune was designed during World War 2 with the prototype flying on 17 May 1945.

They were good and reliable and the last ones were withdrawn from military service in 1984 after 1,177 had been manufactured.

The RAAF took delivery of twelve early P-2E Neptune in 1951 and then another twelve improved SP-2Hs in 1962. They remained in service until 1977s.
