The P-3 Orion is a land-based, long-range, anti-submarine warfare patrol aircraft, in operation since the 1960s. The current model, P-3C Update III, and the signals intelligence variant, the EP-3E Aries, are still in service and performing missions all over the world.
It was intended to replace the piston-engined Lockheed P2V Neptune (later redesignated P-2) and Martin P5M Marlin (later redesignated P-5).
Lockheed based the P-3 on the L-188 Electra commercial airliner. The aircraft is easily distinguished from the Electra by its the tail stinger or "MAD Boom", used for the magnetic detection of submarines.

Over the years, the Orion has seen numerous design developments, most notably in its electronics packages. Numerous navies and air forces around the world continue to use the P-3, primarily for maritime patrol, reconnaissance, anti-surface warfare and anti-submarine warfare.
A total of 757 P-3s have been built. Early models included the P-3A and P-3B, and later the P-3C. With more than 400 aircraft worldwide flown by 21 operators in 17 countries, the P-3 remains a relied-upon asset in 2020.
The Boeing P-8 Poseidon now in production and deployment to the Navy, will eventually replace the remaining P-3C aircraft in the Navy fleet.
