The Lockheed P-3 Orion is a long-range maritime patrol and anti-submarine warfare (ASW) aircraft developed in the 1950s and introduced in the 1960s. It has been one of the primary workhorses of the U.S. Navy for maritime reconnaissance, surveillance, and anti-submarine operations for decades, though many have now been supplemented or replaced by the P-8 Poseidon.
