The Lockheed P-3 Orion maritime surveillance aircraft underwent a number of variants and specific unique design elements. The following is an extensive catalogue of each variant and/or design stage of the aircraft. For a broader article on the history of the P-3, see Lockheed P-3 Orion.
ELINT training aircraft for the Japanese Maritime Self-Defense Force.
One P-3C modified on production line to optimize MAD capabilities. The aircraft did extensive geomagnetic surveys under Project Magnet. In 1973, the RP-3D was instrumental in pinpointing the wreckage of Civil War ironclad USS Monitor.
The Lockheed WP-3D Orion is a production line variant of the P-3 Orion used by the Aircraft Operations Center division of the National Oceanic and Atmospheric Administration (NOAA) at Lakeland Linder International Airport, [13] [14] Florida. Only two of these craft exist, each incorporating numerous features for the role of collecting weather information. During hurricane season, the WP-3Ds are deployed for duty as hurricane hunters.
10 P-3A and 2 EP-3B aircraft converted into ELINT aircraft.
The EP-3E Aries II are 12 P-3C aircraft converted into ELINT aircraft.
Eight US Navy EP-3E aircraft are to be[ when? ] converted by L-3 Communications Integrated Systems into "surge configuration" Signals Intelligence aircraft. This will expand their multi-source intelligence capacity to meet the increased intelligence demands of the "surge" in counter-terrorism operations. [15] [ needs update ]
Various aircraft used for tests.
Six P-3F Orions delivered to the former Imperial Iranian Air Force in the late 1970s.
The airframe of the P-3F was based on the P-3C, which was the then-current production variant of the P-3 for the USN. Unlike production model P-3Cs and CP-140/140As, the P-3F lacked the small fin-top UHF antenna. The P-3F did not have the ASW suite or mission computer of the P-3C and most of the displays and processors were adapted from the older P-3A and P-3B (although the P-3F had the APS-115 radar of the P-3C). The P-3Fs came from the factory with the then-standard gray and white U.S Navy paint scheme, but while crews were undergoing training in the US, the aircraft were repainted in a unique three-tone blue paint scheme.
Three aircraft are still operational with the Islamic Republic of Iran Air Force (IRIAF).
Original designation of the proposed Lockheed P-7A.
Proposed P-3C upgrade.
Two P-3A aircraft modified for FEWSG use as a simulated adversary EW platform in exercises; later transferred from FEWSG to the former Tactical Electronic Warfare Squadron Thirty-Three (VAQ-33) at NAS Key West, Florida, providing adversary electronic warfare services for Fleet training. Upon disbandment of VAQ-33, the aircraft were transferred to Patrol Squadron 66 at NAS Willow Grove and 2 years later to the newly commissioned Fleet Air Reconnaissance Squadron Eleven (VQ-11) of the Navy Reserve at NAS Brunswick, Maine, continuing the previous role of VAQ-33. The aircraft were retired at the disbandment of VQ-11 as part of a post-Cold War force reduction of the Naval Air Reserve.
Five aircraft originally of P-3B standard but subsequently updated, delivered to New Zealand in 1965–67, replacing Short Sunderlands. The original P-3B aircraft were operated by No. 5 Squadron RNZAF from Whenuapai, Auckland. These received part of the P-3C Update II package and some local innovations, then being designated P-3K (for Kiwi), together with a P-3B purchased second hand from the Royal Australian Air Force and brought up to P-3K standard.
P-3K2: Upgraded P-3K, all 6 aircraft were re-winged and underwent a further round of avionics and sensor updates in 2005. [16] In January 2023 all six aircraft were retired, having been replaced with four Boeing P-8 Poseidon aircraft. [17]
Five former Royal Norwegian Air Force (RNoAF) P-3B modernized by EADS-CASA for the Spanish AF. They have a new sensor suite integrated by a six console EADS-CASA Fully Integrated Tactical System (FITS)data system. New sensors include an Elta-2022 radar, SPAS-16 acoustic processor, new 99-channel sonobuoy receiver and AMES-C ESM system. Only the original MAD system was kept.
Two P-3B modified for coast guard missions for the RNoAF.
Six ex-Royal Australian Air Force aircraft originally of P-3B standard but subsequently updated for the Portuguese Air Force. Being replaced by newer P-3C Update II.5s (P-3C CUP) formerly operated by the Royal Netherlands Navy.
The P-3T consists of two former USN P-3As modified for the Royal Thai Navy.
The VP-3T is a single former USN P-3A modified for Royal Thai Navy VIP use and some surveillance operations.
Designation used internally by the RAAF to distinguish the first 10 P-3C aircraft procured in the P-3C Update 2 configuration (1978–79) from the second 10 aircraft which were procured in the Update 2.5 configuration (1982–83). The older aircraft were designated as P-3C and the newer aircraft P-3W. All were equipped with the British AQS-901 Acoustics Processor. Eventually with various system upgrades to the mission systems the two types merged into one and they are now all known as AP-3C.
The Lockheed AP-3C Orion is a variant of the P-3 Orion used by the Royal Australian Air Force (RAAF) for tasks such as naval fleet support, maritime surveillance, search and survivor supply and anti-surface and anti-submarine warfare. They are fitted with a variety of sensors. They include digital multi-mode radar, electronic support measures, electro-optics detectors (infra-red and visual), magnetic anomaly detectors, identification friend or foe systems, and acoustic detectors. The 18 AP-3C Orions were upgraded from P-3Cs between 1997 and 2005, with the program taking three years longer than expected due to systems integration problems. All 18 AP-3C Orions are operated by No. 92 Wing which is based at RAAF Base Edinburgh in South Australia. Aircraft from the wing have seen service as part of Australian Defence Force operations in Australia, South East Asia and the Middle East. [18]
All Royal Australian Air Force P-3C/W aircraft which have been fully upgraded with totally new mission systems by L-3 Communications to include an Elta SAR/ISAR RADAR and a GD-Canada Acoustic Processor system.
The TAP-3 is 3 modified B-models for training duties with the Royal Australian Air Force, with all the ASW gear removed and passenger seating installed. Removed from service with the full introduction into service of the AP-3C Simulator. Designator reflected them as being 'Training Australian P-3'
Five AP-3Cs were purchased by MHD-ROCKLAND in 2018. The aircraft are on the US FAA registry as type 285D, and are based in Keystone Heights, FL. [19] [ better source needed ]
Designation of the eight former USN P-3B TACNAVMOD 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. These use the Vpx ENhanced Open architecture Multi-static(VENOM) acoustic processor system instead of the AN/USQ-78B installed in the aircraft of the United States and trusted allies. [20]
Originally nicknamed "Sentinel". Eight P-3B aircraft were converted into Airborne Early Warning and Control aircraft. In the early 90s, "Control" was dropped from the official designation along with the corresponding "C", renaming the model "P-3-AEW". This made it more easily differentiated from the E-3-AWACS operated by the U.S.Air Force. The P-3-AEWs are used by U.S. Customs and Border Protection's Air and Marine Operations for drug interdiction and homeland security missions. "P-3-LRT" (Long Range Tracker), previously known as "Slicks", also operated by CBP, are modified P-3 aircraft with an optical sensor turret in the nose and tracking radar which often work with the AEW ships. The mission using both types of aircraft in a single mission is called "Double Eagle".
The Lockheed CP-140 Aurora is a Royal Canadian Air Force maritime patrol aircraft (MPA). The aircraft is based on the P-3 Orion airframe, but mounts the electronics suite of the Lockheed S-3 Viking. In Greek mythology, Aurora is the Greek goddess who restored Orion's eyesight, and the Aurora Borealis are the "northern lights" that are prominent over northern Canada and the Arctic Ocean. Eighteen were built.
The CP-140A Arcturus is a related variant used primarily for pilot training and coastal surface patrol missions. It is not equipped with ASW equipment. Three were built.
The Lockheed P-7 was a four turboprop-engined patrol aircraft ordered by the US Navy as a replacement for the P-3 Orion. The external configuration of the aircraft was to be very similar to that of the P-3. Development had not progressed very much before the program was cancelled in the early 1990s, as a cost-cutting measure following the end of the Cold War.
Proposed new-build and improved variant as a P-3 Orion replacement; lost to the Boeing P-8 Poseidon.
The Boeing E-3 Sentry is an American airborne early warning and control (AEW&C) aircraft developed by Boeing. E-3s are commonly known as AWACS. Derived from the Boeing 707 airliner, it provides all-weather surveillance, command, control, and communications, and is used by the United States Air Force, NATO, French Air and Space Force, Royal Saudi Air Force and Chilean Air Force. The E-3 has a distinctive rotating radar dome (rotodome) above the fuselage. Production ended in 1992 after 68 aircraft had been built.
The Lockheed S-3 Viking is a four-crew, twin-engine turbofan-powered jet aircraft designed and produced by the American aerospace manufacturer Lockheed Corporation. Because of its characteristic sound, it was nicknamed the "War Hoover" after the vacuum cleaner brand.
The Sikorsky SH-3 Sea King is an American twin-engined anti-submarine warfare (ASW) helicopter designed and built by Sikorsky Aircraft. A landmark design, it was one of the first ASW rotorcraft to use turboshaft engines.
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; it is easily distinguished from the Electra by its distinctive tail stinger or "MAD" boom, used for the magnetic anomaly detection (MAD) of submarines.
The Lockheed EP-3 is an electronic signals reconnaissance variant of the P-3 Orion, primarily operated by the United States Navy.
The Douglas A-3 Skywarrior is a jet-powered strategic bomber that was developed and produced by the Douglas Aircraft Company. It was designed by Douglas on behalf of the United States Navy, which sought a carrier-capable strategic bomber. In July 1949, Douglas was awarded the contract to produce its design, having bested eight other aircraft companies' submissions. Unlike rival designs, which had aimed for a 100,000 lb (45,000 kg) maximum take-off weight, the Skywarrior was developed for a 68,000 lb (31,000 kg) take-off weight, facilitating its use from the navy's existing Midway-class aircraft carriers. Large portions of the aircraft were produced by the Westinghouse Electric Corporation, including its early Westinghouse J40 turbojet engines, which failed to meet promises and were replaced by the rival Pratt & Whitney J57 engine by mid-1953. On 28 October 1952, the prototype XA3D-1 performed the type's maiden flight.
The Lockheed P-2 Neptune is a maritime patrol and anti-submarine warfare (ASW) aircraft. It was developed for the US Navy by Lockheed to replace the Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion. Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched, stop-gap nuclear bombers that would have to land on shore or ditch. The type was successful in export, and saw service with several armed forces.
The Lockheed EC-121 Warning Star was an American airborne early warning and control radar surveillance aircraft operational in the 1950s in both the United States Navy (USN) and United States Air Force (USAF).
A naval flight officer (NFO) is a commissioned officer in the United States Navy or United States Marine Corps who specializes in airborne weapons and sensor systems. NFOs are not pilots (naval aviators), but they may perform many "co-pilot" or "mission specialist" functions, depending on the type of aircraft. Until 1966, their duties were performed by both commissioned officer and senior enlisted naval aviation observers (NAO).
The Lockheed AP-3C Orion is a variant of the P-3 Orion used by the Royal Australian Air Force (RAAF) for tasks such as naval fleet support, maritime surveillance, search and survivor supply and anti-surface and anti-submarine warfare. The 18 AP-3C Orions were upgraded from P-3Cs between 1997 and 2005, with the program taking three years longer than expected due to systems integration problems. All 18 AP-3C Orions are operated by No. 92 Wing which is based at RAAF Base Edinburgh in South Australia. Aircraft from the wing have seen service as part of Australian Defence Force operations in Australia, South East Asia and the Middle East.
The Miles M.3 Falcon is a 1930s British three/four-seat cabin monoplane aircraft designed by Miles Aircraft Limited.
