The Lockheed P-3 Orion is a four-engined, turboprop anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s. It is based on the L-188 Electra commercial airliner by Lockheed; it is easily distinguished from the Electra by its distinctive tail stinger or "MAD" boom, used for the magnetic anomaly detection (MAD) of submarines.
Over the years, the P-3 has seen numerous design developments, most notably in its electronics packages. Numerous navies and air forces around the world continue to use the type primarily for maritime patrol, reconnaissance, anti-surface warfare and anti-submarine warfare. A total of 757 P-3s have been built. In 2012, it joined the handful of military aircraft including the Boeing B-52 Stratofortress, Boeing KC-135 Stratotanker, and Lockheed C-130 Hercules that the United States military has been using for more than 50 years. In the twenty-first century, the turbofan-powered Boeing P-8 Poseidon began to supplement, and will eventually replace, the U.S. Navy's P-3s.
