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. Lockheed based it on the L-188 Electra commercial airliner.
The aircraft 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 aircraft 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 Orion, primarily for maritime patrol, reconnaissance, anti-surface warfare and anti-submarine warfare. Design: The P-3 has an internal bomb bay under the front fuselage, which can house conventional Mk.50 torpedoes or Mk.46 torpedoes. The P-3 is equipped with a MAD in the extended tail. This instrument is able to detect the magnetic anomaly of a submarine in the Earth's magnetic field. The limited range of this instrument requires the aircraft to be near the submarine at low altitude. Because of this, it is primarily used for pinpointing the location of a submarine immediately prior to a torpedo or depth bomb attack. Due to the sensitivity of the detector, electromagnetic noise can interfere with it, so the detector is placed in P-3's fiberglass tail stinger (MAD boom), far from other electronics and ferrous metals on the aircraft.
