A P-3C Orion of Patrol Squadron 22 (VP-22) flies over Japan, 1 December 1991. | |
Role | Maritime patrol aircraft |
National origin | United States |
Manufacturer | Lockheed Lockheed Martin Kawasaki Heavy Industries |
First flight | November 1959[1] |
Introduction | August 1962[1] |
Status | Active |
Primary users | United States Navy Japan Maritime Self-Defense Force Royal Australian Air Force Republic of Korea Navy |
Produced | 1961–1990[2] |
Number built | Lockheed – 650, Kawasaki – 107, Total – 757[3] |
Developed from | Lockheed L-188 Electra |
Variants | Lockheed AP-3C Orion Lockheed CP-140 Aurora Lockheed EP-3 Lockheed WP-3D Orion |
Developed into | Lockheed P-7 |
The Lockheed P-3 Orion is a four-engine 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.[4] The aircraft is easily distinguished from the Electra by its distinctive tail stinger or "MAD Boom", used for the magnetic detection of submarines.
Over the years, the aircraft has seen numerous design advancements, most notably to its electronics packages. The P-3 Orion is still in use by numerous navies and air forces around the world, primarily for maritime patrol, reconnaissance, anti-surface warfare and anti-submarine warfare.[1] A total of 734 P-3s have been built, and in 2012, it joined the handful of military aircraft including the Boeing B-52 Stratofortress, Boeing KC-135 Stratotanker, Lockheed C-130 Hercules and the Lockheed U-2 that have seen over 50 years of continuous use by the United States military. The U.S. Navy's remaining P-3C aircraft will eventually be replaced by the P-8A Poseidon.
Development
Origins
In August 1957, the U.S. Navy called for replacement proposals for the piston engined Lockheed P2V Neptune (later redesignated P-2) and Martin P5M Marlin (later redesignated P-5) with a more advanced aircraft to conduct maritime patrol and anti-submarine warfare. Modifying an existing aircraft was expected to save on cost and allow rapid introduction into the fleet. Lockheed suggested a military version of their L-188 Electra, which was still in development and had yet to fly. In April 1958, Lockheed won the competition and was awarded an initial research and development contract in May.[4]
![](http://upload.wikimedia.org/wikipedia/commons/thumb/4/4c/P-3_prototype_NAN1-59.jpg/220px-P-3_prototype_NAN1-59.jpg)
The prototype YP3V-1/YP-3A, Bureau Number (BuNo) 148276 was modified from the third Electra airframe c/n 1003.[5] The first flight of the aircraft's aerodynamic prototype, originally designated YP3V-1, was on 19 August 1958. While based on the same design philosophy as the Lockheed L-188 Electra, the aircraft was structurally different. The aircraft had 7 feet (2.1 m) less fuselage forward of the wings with an opening bomb bay, and a more pointed nose radome, distinctive tail "stinger" for detection of submarines by magnetic anomaly detector, wing hardpoints, and other internal, external, and airframe production technique enhancements.[4] The Orion has four Allison T56 turboprops which give it a top speed of 411 knots (761 km/h; 473 mph) comparable to the fastest propeller fighters, or even slow high-bypass turbofan jets such as the Fairchild Republic A-10 Thunderbolt II or the Lockheed S-3 Viking. Similar patrol aircraft include the Soviet Ilyushin Il-38, the French Breguet Atlantique and the British jet-powered Hawker Siddeley Nimrod based on the de Havilland Comet.
The first production version, designated P3V-1, was launched on 15 April 1961. Initial squadron deliveries to Patrol Squadron Eight (VP-8) and Patrol Squadron Forty Four (VP-44) at Naval Air Station Patuxent River, Maryland began in August 1962. On 18 September 1962, the U.S. military transitioned to a unified designation system for all services, with the aircraft being renamed the P-3 Orion.[4] Paint schemes have changed from early 1960s gloss blue and white, to mid-1960s gloss white and gray, to mid-1990s flat finish low visibility gray with fewer and smaller markings. In the early 2000s, the scheme changed to a gloss gray finish with the original full-size color markings. Large size Bureau Numbers on the vertical stabilizer and squadron designations on the fuselage remained omitted.[6]

In 1963, the U.S. Navy Bureau of Weapons (BuWeps) contracted Univac Defense Systems Division of Sperry-Rand to engineer, build and test a digital computer (then in its infancy) to interface with the many sensors and newly developing display units of the P-3 Orion. Project A-NEW was the engineering system which, after several early trials, produced the engineering prototype, the CP-823/U, Univac 1830, Serial A-1, A-NEW MOD3 Computing System. The CP-823/U was delivered to the Naval Air Development Center (NADC) at Johnsville, Pennsylvania in 1965, and directly led to the production computers later equipped on the P-3C Orion.[7]
Three civilian Electras were lost in fatal accidents between February 1959 and March 1960. Following the third crash the FAA restricted the maximum speed of Electras until the cause could be determined. After an extensive investigation, two of the crashes (in September 1959 and March 1960) were found to be caused by insufficiently strong engine mounts, unable to damp a whirling motion that could affect the outboard engines. When the oscillation was transmitted to the wings, a severe vertical vibration escalated until the wings were torn from the aircraft.[8][9] The company implemented an expensive modification program, labelled the Lockheed Electra Achievement Program or LEAP, in which the engine mounts and wing structures supporting the mounts were strengthened, and some wing skins replaced with thicker material. All the surviving Electras of the 145 built at that time were modified at Lockheed's expense at the factory, the modifications taking 20 days for each aircraft. The changes were incorporated in subsequent aircraft as they were built.[8]
Sales of airliners were limited as the technical fix did not completely erase the "jinxed" reputation, turboprop-powered aircraft were soon replaced by faster jets.[10] In a military role where fuel efficiency was more valued than speed, the Orion has been in service over 50 years after its 1962 introduction. Although surpassed in production longevity by the Lockheed C-130 Hercules, 734 P-3s were produced through 1990.[2][11] Lockheed Martin opened a new P-3 wing production line in 2008 as part of its Service Life Extension Program (ASLEP) for delivery in 2010. A complete ASLEP replaces the outer wings, center wing lower section and horizontal stabilizers with newly built parts.[12]
In the 1990s, during a U.S. Navy attempt to identify a successor aircraft to the P-3, the improved P-7 was selected over a navalized variant of the twin turbofan-powered Boeing 757, but this program was subsequently cancelled. In a second program to procure a successor, the advanced Lockheed Martin Orion 21, another P-3 derived aircraft, lost out to the Boeing P-8 Poseidon, a Boeing 737 variant, which entered service in 2013.
Design

![](http://upload.wikimedia.org/wikipedia/commons/thumb/2/2d/P-3_Orion_underside_view_20080614.jpg/220px-P-3_Orion_underside_view_20080614.jpg)
The P-3 has an internal bomb bay under the front fuselage which can house conventional Mark 50 torpedoes or Mark 46 torpedoes and/or special (nuclear) weapons. Additional underwing stations, or pylons, can carry other armament configurations including the AGM-84 Harpoon, AGM-84E SLAM, AGM-84H/K SLAM-ER, the AGM-65 Maverick, 127 millimetres (5.0 in) Zuni rockets, and various other sea mines, missiles, and gravity bombs. The aircraft also had the capability to carry the AGM-12 Bullpup guided missile until that weapon was withdrawn from U.S./NATO/Allied service.[13]
The P-3 is equipped with a magnetic anomaly detector (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.[14]
Crew complement
The crew complement varies depending on the role being flown, the variant being operated, and the country that is operating the type. In U.S. Navy service, the normal crew complement was 12 until it was reduced to its current complement of 11 in the early 2000s when the in-flight ordnanceman (ORD) position was eliminated as a cost-savings measure and the ORD duties assumed by the in-flight technician (IFT).[1] Data for U.S. Navy P-3C only.
Officers:
- three Naval Aviators
- Patrol Plane Commander (PPC)
- Patrol Plane 2nd Pilot (PP2P)
- Patrol Plane 3rd Pilot (PP3P)
- two Naval Flight Officers
- Patrol Plane Tactical Coordinator (PPTC or TACCO)
- Patrol Plane Navigator/Communicator (PPNC or NAVCOM)
NOTE: NAVCOM on P-3C only; USN P-3A and P-3B series had an NFO Navigator (TACNAV) and an enlisted Airborne Radio Operator (RO)
Enlisted Aircrew:
- two enlisted Aircrew Flight Engineers (FE1 and FE2)

- one enlisted Aviation Ordnanceman (ORD position no longer used on USN crews; duties assumed by IFT.)
The senior of either the PPC or TACCO will be designated as the aircraft Mission Commander (MC).
Engine loiter shutdown
Once on station, one engine is often shut down (usually the No. 1 engine – the left outer engine) to conserve fuel and extend the time aloft and/or range when at low level. It is the primary candidate for loiter shutdown because it has no generator. Eliminating the exhaust from engine 1 also improves visibility from the aft observer station on the port side of the aircraft.
On occasion, both outboard engines can be shut down, weight, weather, and fuel permitting. Long deep-water, coastal or border patrol missions can last over 10 hours and may include extra crew. The record time aloft for a P-3 is 21.5 hours, undertaken by the Royal New Zealand Air Force's No. 5 Squadron in 1972.
Operational history
United States
![](http://upload.wikimedia.org/wikipedia/commons/thumb/7/7e/P-3C_Orion2.jpg/220px-P-3C_Orion2.jpg)
![](http://upload.wikimedia.org/wikipedia/commons/thumb/e/ed/Two_man_replace_a_main_landing_gear_tire_of_a_plane.jpg/220px-Two_man_replace_a_main_landing_gear_tire_of_a_plane.jpg)
Developed during the Cold War, the P-3's primary mission was to track Soviet Navy ballistic missile and fast attack submarines and to eliminate them in the event of full-scale war. At its height, the U.S. Navy's P-3 community consisted of twenty-four active duty "Fleet" patrol squadrons home based at air stations in the states of Florida and Hawaii as well as bases which formerly had P-3 operations in Maryland, Maine, and California. There were also thirteen Naval Reserve patrol squadrons identical to their active duty "Fleet" counterparts, said Reserve "Fleet" squadrons being based in Florida, Pennsylvania, Maryland, Michigan, Massachusetts (later relocated to Maine), Illinois, Tennessee, Louisiana, California and Washington. Two Fleet Replacement Squadrons (FRS), also called "RAG" squadrons (from the historic "Replacement Air Group" nomenclature) were located in California and Florida. The since-deactivated VP-31 in California provided P-3 training for the Pacific Fleet, while VP-30 in Florida performed the task for the Atlantic Fleet. These squadrons were also augmented by a test and evaluation squadron in Maryland, two additional test and evaluation units that were part of an air development center in Pennsylvania and a test center in California, an oceanographic development squadron in Maryland, and two active duty "special projects" units in Texas and Hawaii, the latter being slightly smaller than a typical squadron.
Reconnaissance missions in international waters led to occasions where Soviet fighters would "bump" a P-3, either operated by the U.S. Navy or other operators such as the Royal Norwegian Air Force. On 1 April 2001, a midair collision between a United States Navy EP-3E ARIES II signals surveillance aircraft and a People's Liberation Army Navy J-8II jet fighter-interceptor resulted in an international dispute between the U.S. and the People's Republic of China (PRC).[15]
More than 40 combatant and noncombatant P-3 variants have demonstrated the rugged reliability displayed by the platform flying 12-hour plus missions 200 ft (61 m) over salt water while maintaining an excellent safety record. Versions have been developed for the National Oceanic and Atmospheric Administration (NOAA) for research and hurricane hunting/hurricane wall busting, for the U.S. Customs Service (now U.S. Customs and Border Protection) for drug interdiction and aerial surveillance mission with a rotodome adapted from the Grumman E-2 Hawkeye or an AN/APG-66 radar adapted from the General Dynamics F-16 Fighting Falcon, and for NASA for research and development.
The U.S. Navy remains the largest P-3 operator, currently distributed between a single fleet replacement (i.e., "training") patrol squadron in Florida (VP-30), 12 active duty patrol squadrons distributed between bases in Florida, Washington and Hawaii, two Navy Reserve patrol squadrons in Florida and Washington, one active duty special projects patrol squadron (VPU-2) in Hawaii, and two active duty test and evaluation squadrons. One additional active duty fleet reconnaissance squadron (VQ-1) operates the EP-3 Aries signals intelligence (SIGINT) variant at Naval Air Station Whidbey Island, Washington.
In January 2011, the U.S. Navy revealed that P-3s have been used to hunt down "third generation" narco subs.[16] This is significant because as recently as July 2009, fully submersible submarines have been used in smuggling operations.[17]
In Cuba
In October 1962, P-3A aircraft flew several blockade patrols in the vicinity of Cuba. Having just recently joined the operational Fleet earlier that year, this was the first employment of the P-3 in a real world "near conflict" situation.
In Vietnam
Beginning in 1964, forward deployed P-3 aircraft began flying a variety of missions under Operation Market Time from bases in the Philippines and Vietnam. The primary focus of these coastal patrols was to stem the supply of materials to the Viet Cong by sea, although several of these missions also became overland "feet dry" sorties. During one such mission, a small caliber artillery shell passed through a P-3 without rendering it mission incapable. The only confirmed combat loss of a P-3 also occurred during Operation Market Time. In April 1968, a U.S. Navy P-3B of VP-26 was downed by anti-aircraft fire in the Gulf of Thailand with the loss of the entire crew. Two months earlier, in February 1968, another one of VP-26's P-3B aircraft was operating in the same vicinity when it crashed with the loss of the entire crew. Originally attributed to an aircraft mishap at low altitude, later conjecture is that this aircraft may have also fallen victim to AAA fire from the same source as the April incident.[18]
In Iraq
On 2 August 1990, Iraq invaded Kuwait and was poised to strike Saudi Arabia. Within 48 hours of the initial invasion, U.S. Navy P-3C aircraft were among the first American forces to arrive in the area. One was a modified platform with a prototype system known as "Outlaw Hunter". Undergoing trials in the Pacific after being developed by the Navy’s Space & Naval Warfare Systems Command (SPAWAR), "Outlaw Hunter" was testing a specialized over-the-horizon targeting (OTH-T) system package when it responded. Within hours of the start of the coalition air campaign, "Outlaw Hunter" detected a large number of Iraqi patrol boats and naval vessels attempting to move from Basra and Umm Qasr to Iranian waters. "Outlaw Hunter" vectored in strike elements which attacked the flotilla near Bubiyan Island destroying 11 vessels and damaging scores more. During Desert Shield, a P-3 using infrared imaging detected a ship with Iraqi markings beneath freshly-painted bogus Egyptian markings trying to avoid detection. Several days before the 7 January 1991 commencement of Operation Desert Storm, a P-3C equipped with an APS-137 Inverse Synthetic Aperture Radar (ISAR) conducted coastal surveillance along Iraq and Kuwait to provide pre-strike reconnaissance on enemy military installations. A total of 55 of the 108 Iraqi vessels destroyed during the conflict were targeted by P-3C aircraft.[19]
The P-3 Orion's mission expanded in the late 1990s and early 2000s to include battlespace surveillance both at sea and over land. The long range and long loiter time of the P-3 Orion have proved to be an invaluable asset during Operation Iraqi Freedom and Operation Enduring Freedom. It can instantaneously provide information about the battlespace it can see to ground troops, particularly the U.S. Marines.[1]
In Afghanistan
Although the P-3 is a Maritime Patrol Aircraft, armament and sensor upgrades in the Anti-surface Warfare Improvement Program (AIP)[20] have made it suitable for sustained combat air support over land.[20] Since the start of the current war in Afghanistan, U.S. Navy P-3 aircraft have been operating from Kandahar in that role.[21] Royal Australian Air Force AP-3C Orions operated out of Minhad Air Base in the UAE from 2003 until their withdrawal in November 2012. During the period 2008–2012, the AP-3C Orions conducted overland intelligence, surveillance and reconnaissance tasks in support of coalition troops throughout Afghanistan.[22]
Recently, the United States Geological Survey used the Orion to survey parts of southern and eastern Afghanistan for lithium, copper, and other mineral deposits.[23]
In Libya
Several U.S. Navy P-3C Orions, and two Canadian CP-140 Auroras, a variant of the Orion, have participated in maritime surveillance missions over Libyan waters in the framework of enforcement of the 2011 no-fly zone over Libya.[24][25]
A U.S. Navy P-3C Orion supporting Operation Odyssey Dawn engaged the Libyan coast guard vessel Vittoria on 28 March 2011 after the vessel and two smaller craft fired on merchant ships in the port of Misrata, Libya. The Orion fired AGM-65 Maverick missiles on Vittoria, which was subsequently beached.[26]
Iran

Lockheed produced the P-3F variant of the P-3 Orion, for Iran. Six examples were delivered to the former Imperial Iranian Air Force (IIAF) in 1975 and 1976.
Following the Iranian Revolution in 1979, the Orions continued in service, after the IIAF was renamed the Islamic Republic of Iran Air Force (IRIAF). They were used in the Tanker War phase of the Iran–Iraq War and were operated by one of the most successful squadrons of the IRIAF during that conflict. A total of four P-3Fs remain in service.
Pakistan
![](http://upload.wikimedia.org/wikipedia/commons/thumb/2/2b/Pakistan_Navy_Orion_Asuspine.jpg/220px-Pakistan_Navy_Orion_Asuspine.jpg)
Three P-3C Orions, delivered to the Pakistan Navy in 1996 and 1997 were operated extensively during the Kargil conflict. After the crash of one, the type was grounded due to the loss of an entire crew; nonetheless, the aircraft were maintained in an armed state and airworthy condition throughout the escalation period of 2001 and 2002. In 2007, they were used by the navy to conduct signals intelligence, airborne and bombing operations in a Swat offensive and Operation Rah-e-Nijat. Precision and strategic bombing missions were carried out by the Orions, and in 2007, intelligence management operations were conducted against Taliban and al-Qaeda operatives.[27]
On 22 May 2011, two out of the four Pakistani P-3Cs were destroyed in an attack on PNS Mehran, a Pakistani Naval station in Karachi.[28] The Pakistani fleet had been readily used in overland, counter-insurgency operations. In June 2011, the U.S. agreed to replace the destroyed aircraft with two new ones, with delivery to follow later.[29] In February 2012, the U.S. delivered two, additional P-3C Orion aircraft to the Pakistan Navy.[30]
In Somalia
![](http://upload.wikimedia.org/wikipedia/commons/thumb/3/3b/Maersk_Alabama%2C_seen_by_P-3C_Orion.jpg/220px-Maersk_Alabama%2C_seen_by_P-3C_Orion.jpg)
The Spanish Air Force deployed P-3s to assist the international effort against piracy in Somalia. On 29 October 2008, a Spanish P-3 aircraft patrolling the coast of Somalia reacted to a distress call from an oil tanker in the Gulf of Aden. To deter the pirates, the aircraft flew over the pirates three times as they attempted to board the tanker, dropping a smoke bomb on each pass. After the third pass, the attacking pirate boats broke off their attack.[31] Later, on 29 March 2009, the same P-3 pursued the assailants of the German navy tanker Spessart (A1442), resulting in the capture of the pirates.[32]
In April 2011, the Portuguese Air Force also contributed to Operation Ocean Shield by sending a P-3C[33] which had early success when on its fifth mission detected a pirate whaler with two attack skiffs.[34]
Since 2009 the Japan Maritime Self-Defense Force has deployed P-3s to Djibouti for anti-piracy patrols,[35][36][37] from 2011 from its own base.[38]
Civilian uses
![](http://upload.wikimedia.org/wikipedia/commons/thumb/4/45/Fox-firebase-aero_union-N920AU-070904-02-24.jpg/220px-Fox-firebase-aero_union-N920AU-070904-02-24.jpg)
Several P-3 aircraft have been N-registered and are operated by civilian agencies. The US Customs and Border Protection has a number of P-3A and P-3B aircraft that are used for aircraft intercept and maritime patrol. NOAA operates two WP-3D variants specially modified for hurricane research. One P-3B, N426NA, is used by National Aeronautics and Space Administration (NASA) as an Earth science research platform, primarily for the NASA Science Mission Directorate's Airborne Science Program. It is based at Goddard Space Flight Center's Wallops Flight Facility, Virginia.
Aero Union, Inc. operated eight ex-USN P-3A aircraft configured as air tankers, which were leased to the U.S. Forest Service, the California Department of Forestry and Fire Protection and other agencies for firefighting use. Several of these aircraft were involved in the U.S. Forest Service airtanker scandal but have not been involved in any catastrophic aircraft mishaps. Aero Union has since gone bankrupt, and their P-3s have been put up for auction.[39]
Variants
![](http://upload.wikimedia.org/wikipedia/commons/thumb/8/84/JMSDF_UP-3C_Orion.jpg/220px-JMSDF_UP-3C_Orion.jpg)
Over the years, numerous variants of the P-3 have been created. A few notable examples are:
- WP-3D: Two P-3C aircraft as modified on the production line for NOAA weather research, including hurricane hunting.
- EP-3E Aries: 10 P-3A and 2 EP-3B aircraft converted into ELINT aircraft.
- EP-3E Aries II: 12 P-3C aircraft converted into ELINT aircraft.
- AP-3C: Royal Australian Air Force P-3C/W aircraft which have been extensively upgraded by L-3 Communications with new mission systems, including an Elta SAR/ISAR radar and a GD-Canada acoustic processor system.
- CP-140 Aurora: Long-range maritime reconnaissance, anti-submarine warfare aircraft for the Canadian Forces. Based on the P-3C Orion airframe, but mounts the more advanced electronics suite of the Lockheed S-3 Viking; 18 built
- CP-140A Arcturus: Three P-3s without ASW equipment for Canadian Aurora crew training and various coastal patrol missions.
- P-7 proposed new-build and improved variant as a P-3 Orion replacement later canceled.
- Orion 21 proposed new-build and improved variant as a P-3 Orion replacement; lost to the Boeing P-8 Poseidon.
- P-3K2: Royal New Zealand Air Force P-3K2 aircraft which have been fully upgraded with totally new mission systems by L-3 Mission Integration Division, Greenville, Texas. The flight deck now has ‘glass’ instrumentation and navigation computer automation. The Tactical Rail (Tacrail) has been completely refitted with modern sensors, communication and data management systems.

- German Navy – eight P-3C CUP+ (ex Royal Netherlands Navy); based at NAS Nordholz, Marinefliegergeschwader 3 Graf Zeppelin
- Hellenic Air Force – six P-3B operated jointly with the Hellenic Navy, not in operable condition as of 2015, 4 of the planes are undergoing maintenance as of 2016 which should return them to airworthy condition
- Islamic Republic of Iran Air Force – four P-3F (71ASW SQN); based at Shiraz International Airport (Shahid Douran Air Base)
- Japan Maritime Self-Defense Force – 93 P-3C, five EP-3, five OP-3C, one UP-3C, three UP-3D.[44] The Kawasaki Corporation assembled five airframes produced by Lockheed, and then Kawasaki produced more than 100 P-3s under license in Japan.[45] The Kawasaki P-1 is gradually replacing them.
- Royal Netherlands Navy – Netherlands Naval Aviation Service - former operator.[citation needed]
- Royal New Zealand Air Force – six P-3K2 (5 Sqn); based in RNZAF Base Auckland. Operated by 5 SQN. Five were originally delivered in 1966 as P-3Bs. Another was purchased from the RAAF in 1985, following which all were upgraded to their current standard. Currently undergoing various mission system upgrades by L-3 Communications Canada and now designated as P-3K2. Due to be replaced in 2025 with equivalent level of capability, either manned or unmanned.
- Royal Norwegian Air Force – four P-3C, two P-3N (333 Sqn); based in Andøya Air Station
- Pakistan Naval Air Arm – ~Four P-3C; based in Naval aviation base Faisal, Karachi. Upgraded P-3C MPA and P-3B AEW models (equipped with Hawkeye 2000 AEW system) ordered in 2006,[46] first upgraded P-3C delivered in early 2007. In June 2010, two more upgraded P-3Cs joined the Pakistan Navy with anti-ship and submarine warfare capabilities.A total of nine(9).[47] Two aircraft were destroyed in an attack by armed militants at the Mehran Naval Airbase.
- Portuguese Air Force – five P-3C CUP+ (ex Royal Netherlands Navy) operated by 601 Squadron "Lobos", based in Beja Air Base. They replaced six former RAAF P-3Bs upgraded to P-3Ps in the late 1980s. The last P-3P flew on 13 October 2011.
- Republic of Korea Navy – eight P-3Cs, eight P-3CKs; based in Pohang Airport and Jeju international airport. Korean Air/L-3 Communications are upgrading the P-3C aircraft with new electronics, including new magnetic anomaly detectors,electro-optical sensors, surveillance equipment and a self-protection suite. The Navy's impetus stems from a 2010 experience in which ROK forces detected only 28% of North Korean submarines involved in exercises.[48]
- Spanish Air Force – Two P-3A HWs, four P-3B ( ex-Norway) being upgraded to P-3M, based at Morón Air Base. The Spanish AF bought five P-3B from Norway in 1989 and it was planned to upgrade all five to M standard, however, due to budgetary constraints only four are to be upgraded, the remaining aircraft being used as spares source.
- Republic of China Air Force(1966–1967) – Least known of all P-3 family. Three P-3As (149669, 149673, 149678) were obtained by CIA from the U.S. Navy under Project STSPIN in May 1963, as the replacement aircraft for CIA's own covert operation fleet of RB-69A/P2V-7U versions. Converted by Aerosystems Division of LTV at Greenville, Texas, the three P-3As were simply known as "black" P-3As under "Project Axial". Officially transferred from U.S. Navy to CIA on June/July 1964, LTV Aerosystems converted the three aircraft to be both ELINT and COMINT platform. First of three "black" P-3As arrived in Taiwan and officially transferred to ROCAF's top secret Black Bat Squadron on 22 June 1966. Armed with four Sidewinder short range AAM missiles for self-defense, the three "black" P-3A flew peripheral missions along the China coast to collect SIGINT and air samples. When the project was terminated in January 1967, all three "black" P-3As were flown to NAS Alameda, CA, for long term storage. In September 1967, Lockheed at Burbank, converted two of the three aircraft (149669 and 149678) into the only two EP-3B examples in existence in the world, while the third aircraft (149673) was converted by Lockheed in 1969–1970 to serve as a development aircraft for various electronic programs. The two EP-3Bs known as "Bat Rack", owing to their short period of service with Taiwan's "Black Bat" Squadron, were issued to U.S. Navy's VQ-1 Squadron in 1969 and deployed to Da Nang, Vietnam. Later, the two EP-3Bs were converted to EP-3E ARIES, along with seven EP-3As. The two EP-3Es retired in the 1980s, when replaced by 12 EP-3E ARIES II versions.[49]

- 6 March 1969: USN P-3A BuNo 152765 tail coded RP-07 of VP-31 crashed at NAS Lemoore, California, at the end of a practice ground control approach (GCA) landing, all six crew died.
- 28 January 1971: Commander Donald H. Lilienthal, USN flew a P-3C Orion to a world speed record for heavyweight turboprops. Over 15–25 kilometers, he reached 501 miles per hour to break the Soviet Il-18's May 1968 record of 452 miles per hour.
- 26 May 1972: USN P-3A BuNo 152155 disappeared over the Pacific Ocean on a routine training mission after departing NAS Moffett Field, California with the loss of eight crew members.[60]
- 3 June 1972: While attempting to fly through the Straits of Gibraltar, en route from Naval Station Rota, Spain to Naval Air Station Sigonella, Sicily, a U.S. Navy P-3A of VP-44 hit a mountain in Morocco, resulting in the death of all 14 crew on board the aircraft.[61]
- 12 April 1973: A United States Navy P-3C BuNo 157332 operating from NAS Moffett Field, California collided with a Convair CV-990 (N711NA) operated by NASA during approach to runway 32R. The aircraft crashed on the Sunnyvale Municipal Golf Course, 0.5 miles (0.80 km) short of the runway, resulting in destruction of both aircraft and the death of all but one crewmember.[62]
- 11 December 1977: USN P-3B BuNo 153428 from VP-11 operating from Lajes Field, Azores crashed on mountainous El Hierro (southwesternmost of the Canary Islands) in poor visibility. There were no survivors from the crew of 13.[63]
- 26 April 1978: USN P-3B BuNo 152724 from VP-23 crashed on landing approach to Lajes Field, Azores. Seven of the crew were killed and the plane sank into deep water preventing recovery to assess the cause of the crash.[64]
- 22 September 1978: USN P-3B BuNo 152757 from VP-8 disintegrated over Poland, Maine on 22 September 1978. An over-pressurized fuel tank caused the port wing to separate at the outboard engine.[65] The detached wing sheared off part of the tail; and aerodynamic forces caused the remaining engines and starboard wing to detach from the fuselage. Debris rained down near the south end of Tripp Pond shortly after 12:00. There were no survivors from the plane's 8-man crew.[66]
- 26 October 1978: USN P-3C BuNo 159892 call sign coded AF 586 from VP-9 operating from NAS Adak ditched at sea after an engine fire caused by a propeller malfunction. Ten of the 15-man crew were rescued by a Soviet trawler.[67]
- 27 June 1979: P-3B BuNo 154596 from VP-22 operating from NAS Cubi Point Philippines, had a propeller overspeed shortly after departure. The number 4 propeller then departed the aircraft striking the number three with a subsequent fire on that engine. While attempting an overweight landing with 2 engines out, the aircraft stalled, rolled inverted and crashed in Subic Bay just past Grande Island. Four crew and one passenger were killed in the crash.[68]
- 17 April 1980: USN P-3C BuNo 158213 from VP-50 while flying for a parachuting exhibition in Fiji, struck overhead tram wires and crashed, killing all six crew on board.[68]

- 13 September 1987: A Royal Norwegian Air Force P-3B, tail number "602", is hit from below by a Russian Air Force Sukhoi Su-27 of the 941st IAP V-PVO. The Su-27 flew below the P-3's starboard side, then accelerated and pulled up, clipping the #4 engine's propellers. The propeller shrapnel hit the Orion's fuselage and caused a decompression. There were no injuries and both aircraft returned safely to base.[71]
- 25 September 1990: The first production model P-3C Update III, BuNo 161762, assigned to VP-31 at NAS Moffett Field, impacted the runway at an excessive rate of descent while conducting at dedicated field work sortie at Naval Auxiliary Landing Field Crows Landing. Both main landing gear failed and the aircraft slid down the runway. Some crewmembers sustained minor injuries, but there were no fatalities. The aircraft was a total loss.[72]
- 21 March 1991: While on a training mission west of San Diego, California, two U.S. Navy P-3C Orions, BuNos 158930 and 159325 assigned to VP-50 based at NAS Moffett Field collided in midair, killing all 27 crew on board both aircraft.[73]
- 26 April 1991: AP-3C, tail number A9-754 of the Royal Australian Air Force, lost a wing leading edge and crashed into shallow water in the Cocos Island; one crewman was killed.
