P-3C Anti-submarine patrol plane

The P-3C was developed as an anti-submarine plane operated by the US Navy ground base, and is presently being operated by Japanese air self-defense forces as well. The P-3C Orion, which has no high-speed abilities but is capable of long-term flight, was developed based on the Turboprop passenger plane and has a large interior area and loading capabilities, which allow it to carry a lot of electronic equipment. With more advanced data processing equipment, computers, inertial navigation devices and Doppler navigation equipment than the P-3A, the P-3C is not only capable of simple patrol operations, but also acts as an air command control plane as well.
The close-range magnetic detector used to detect submarines (MAD: Magnetic Anomaly Detector) is equipped in the tail and uses changes in the Earth's magnetic filed to detect targets. The underwater sonobuoys that are deployed through the airdrop window installed in the body of the plane detect noise from submarines underwater and transmit electric waves to the P-3C. The P-3C is armed with torpedoes, depth charges, and mines carried in the body and weapons can be carried on the main wing as well.

The Lockheed P-3 Orion is a maritime patrol aircraft of numerous militaries around the world, used primarily for maritime patrol, reconnaissance, and anti-submarine warfare.

Design

The P-3 Orion, originally designated P3V, based on the Lockheed L-188 Electra, which met limited success as a turboprop airliner competing against emerging pure jets. It served as the replacement for the postwar era P-2 Neptune. The Orion is powered by 4 turboprops which give it a speed comparable to fast propeller powered fighters, or even slow turbofan jets such as the A-10. Most other similar patrol aircraft use this model, with Soviets adapting their own counterpart to the Electra. The P-3 also competes with the British Nimrod adaptation of the Comet and the French Breguet Atlantique. Experience with the P-3 helped with the S-3 Viking carrier-borne ASW jet.

The P-3 has an internal bomb bay under the front fuselage, as well as underwing stations which can carry missiles such as the AGM-84 Harpoon. It has a long 'stinger' in the tail which houses the magnetic anomaly detector (MAD), and convex windows for observation. Sonobuoys can be dropped from externally loaded tubes, or from inside the fuselage.

The first production version, designated P3V-1, first flew 15 April 1961, but by the time the first deliveries were made in 1962, the unified designation system made this the P-3. Paint schemes have changed from overall postwar blue, to 1960s white and grey, and 1980s low viz gray.

Over the years many variants have been developed. The technology of the P-3 is similar to the larger, slower, and more successful C-130 Hercules transport. Similar versions have been developed for hurricane hunting, and aerial surveillance with a rotodome adapted from the E-2 Hawkeye. Despite higher performance, the P-3 has not been adapted into gunship or ground attack precision attack platform, aerial refueling tanker, or attempted a carrier landing like the C-130.

The P-3 Orion has found special use as an earth-science suborbital research platform for NASA. Known as callsign NASA 426, this aircraft is located at Goddard Space Flight Center's Wallops Flight Facility, Virginia.

The P-3 is slated for replacement between 2010 - 2013 by the P-8 Poseidon, based upon the Boeing 737 civilian aircraft, which would result in a minimum time of service of 50 years.

Operating the P-3

Crew complement in U.S. service
Ten to twelve (10-12) crew members.

Aircraft Commander or Patrol Plane Commander ("PPC")
Co-pilot ("2P")
Third-pilot ("3P")
Flight Engineer (FE)
Second Flight Engineer (2FE)
Tactical Coordinator (TACCO)
Navigator/Communicator (NAV/COM)
Acoustic Sensor Operator 1 (Sensor 1)
Acoustic Sensor Operator 2 (Sensor 2)
Non-acoustic Sensor Operator, Radar/MAD (Sensor 3)
In-flight Technician (IFT)
Ordnanceman (ORD)**No longer used** (IFT has assumed duties)
Other operators have a varying number of crew on board, depending on their equipment fitout and aircraft role. For example, the Royal Australian Air Force (RAAF) aircraft do not have a dedicated Ordnancemen, with that role on the aircraft being supplied by spare crew members from any of the other categories. Also, the RAAF aircraft operate with a ESM operator (Sensor 4), a Sensor Employment Manager (SEM) and a second Flight Engineer (with no In-Flight technician)

Engine loiter shut-down
On many missions, an engine is often shut down (usually engine Number One, the left outer engine) once on station to extend the time aloft (and range when at low level) by conserving fuel. On occasion both outboard engines will be shutdown, aircraft weight, weather, and remaining fuel permitting. Long border patrol missions can last over 10 hours, and may include extra pilots and crew. The record for the longest flight for a P-3 model is 21.5 hours, on a flight undertaken by the Royal New Zealand Air Force's No. 5 Squadron in 1972.

Engine Number one is the primary engine for 3-engine loiter shutdown because it is the only one of the P-3's four engines that does not have a generator, hence it is not needed for powering onboard electrical systems. It also removes the exhaust stream for that engine, increasing the visibility from the primary observer stations on the port side of the aircraft.

The older aircraft were designated as P-3Cs and the newer aircraft P-3Ws. All were equipped with the British AQS-901 Acoustics Processor. Eventually with various system upgrades to the mission systems the two types mergerd into one and they are now all known as AP-3Cs

P-3CK: Designation of the eight former P-3B aircraft that the Republic of Korea Navy procured from the USN and which are in the process of being rebuilt with P-3C configuration wings and fitted with updated Mission System Equipment by Korea Aerospace Industries and L-3 Communications.
P-3AEW&C (originally nicknamed "Sentinel") : Eight P-3B aircraft were converted into Airborne Early Warning and Control aircraft. The P-3AEW&Cs are used by U.S. Customs and Border Protection for drug interdiction and homeland security missions. "Slicks" are P-3s with an optical sensor turret in the nose which often work with the AEW ships.
CP-140 Aurora : Longe-range maritime reconnaissance, anti-submarine warfare aircraft for the Canadian Armed Forces. It is based on the P-3 Orion airframe, but mounts the more advanced electronics suite of the S-3 Viking.
CP-140A Arcturus : Three CP-140s without the ASW equipment installed for Aurora crew training and various coastal patrol missions.
Orion 21 proposed new-build and improved variant for P-3 Orion replacment;lost to Boeing P-8.
In late 2006, the US announced that it intended to sell three P-3C Orions equipped with the E-2C Hawkeye 2000 AEW system to the Pakistan Navy, along with 10 regular P-3Cs. The AEW aircraft will provide Pakistan with search surveillance, and control capability in support of maritime interdiction operations.[1]
