Lockheed P-3 Orion
Land	Usa
Role	Maritieme patrouillevliegtuigen
Eerste vlucht	November 1959
Gebouwd	650

De Lockheed P-3 Orion is een viermotorig turboprop anti-onderzeeër en maritiem surveillance vliegtuig ontwikkeld voor de Amerikaanse marine en geïntroduceerd in de jaren 1960. Lockheed baseerde het op het L-188 Electra commerciële lijnvliegtuig. Het vliegtuig onderscheidt zich gemakkelijk van de Electra door zijn kenmerkende staartsteeker of "MAD Boom", gebruikt voor de magnetische detectie van onderzeeërs.

The Electra’s Deadly Cousin

De Lockheed P-3C Orion is a four-engine turboprop maritime patrol aircraft that has served the U.S. Navy and dozens of international allies since the 1960s. Based on the L-188 Electra airliner, the P-3 was heavily modified to carry an incredible suite of sub-surface detection equipment. The “C” model, introduced in 1969, featured the Univac ASQ-114 digital computer, which revolutionized anti-submarine warfare (ASW) by allowing the crew to process and integrate data from various sensors in real-time.

Horsepower	4,600 shp (3,430 kW) per engine
Maximum Speed	411 knots (473 mph / 761 km/h)
Combat Range	1,345 nmi (plus 3 hours on station)
Endurance	10–13 hours (typical)

The Tools of the Hunter

MAD Boom: The most recognizable feature is the “stinger” tail, housing the Magnetic Anomaly Detector. It senses minute changes in the Earth’s magnetic field caused by the metal hull of a submerged submarine.
Sonobuoy Chutes: Located in the underbelly are dozens of launch tubes for sonobuoys—disposable acoustic sensors dropped into the ocean to “listen” for propeller noises or pinging hulls.
Internal Weapons Bay: Forward of the wing, the Orion features an unpressurized weapons bay capable of carrying Mk 46 or Mk 54 torpedoes, depth charges, or special nuclear mines.
The “Three-Engine” Loiter: To save fuel and extend time on station, P-3 crews often shut down one of the outboard engines (usually Engine #1) once they reached their search area, taking advantage of the T56 engine’s efficiency.

A Half-Century of Global Vigilance

Cuban Missile Crisis: Early P-3s played a vital role in the blockade of Cuba, tracking Soviet freighters and submarines in the Atlantic.
EP-3 Aries II: A specialized “Electronic Intelligence” (ELINT) version of the Orion is used to intercept communications and radar signals. It became world-famous in 2001 during the “Hainan Island Incident” involving a collision with a Chinese fighter.
The “Hurricane Hunters”: NOAA operates two highly modified P-3s (nicknamed Kermit En Miss Piggy) that fly directly into the eyes of hurricanes to collect meteorological data.
Replacement: After 50 years of service, the P-3C is being replaced in U.S. Navy service by the Boeing P-8 Poseidon, though it remains a front-line asset for countries like Japan, Germany, and Australia.
