1. Локхийд П-3 Орион е четиридвигателен турбовитлов противоподводен и морски наблюдателен самолет, разработен за ВМС на САЩ и въведен през 60-те години на миналия век. Lockheed го основава на търговския самолет L-188 Electra. Самолетът лесно се отличава от Electra по отличителния си ужилвач на опашката или "MAD Boom", използван за магнитно откриване на подводници.

The Electra’s Deadly Cousin

1. Локхийд Р-3С Орион 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.

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 И 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.
