The P-3 Orion is a long-range maritime patrol aircraft (MPA) with multi-mission capabilities. Its 16-hour fly-time and high ferry range of 8,944km make it the top MPA in the world. The aircraft was developed by Lockheed Martin principally for the US Navy. The aircraft entered service in 1962 and is currently in service with 21 operators in 17 countries worldwide.
The aircraft can conduct a variety of missions such as maritime / over-land patrol, anti-submarine warfare, anti-piracy, anti-terrorism, drug interdiction and the prevention of illegal immigration. Lockheed Martin offers a P-3 Mid-Life Upgrade (MLU) programme to extend the aircraft’s service life by 20 to 25 years.
The aircraft can be equipped with infrared and electro-optical (EO) sensors, as well as special imaging radar to detect objects at long ranges. Its large internal weapons bay and ten external hardpoints can house a range of weapons. Four Allison T56-A-14 engines provide the P-3 Orion with a long-range cruise speed of 350k at 25,000ft.
Based on Boeing’s 737-800 Next Generation, the P-8A Poseidon long-range multi-mission maritime aircraft was for the US Navy. The aircraft is capable of performing maritime patrol, anti-submarine and anti-surface warfare, as well as intelligence, surveillance and reconnaissance (ISR) missions. The Indian Navy also operates a P-8A version designated as P-8I.
Boeing completed the maiden flight of the P-8A in April 2009. The aircraft is equipped with Northrop Grumman infrared countermeasures and electronic support measures systems, Raytheon AN/APY-10 radar and MK 54 lightweight torpedo, GE Aviation flight-management and stores-management systems, and air-to-surface / anti-ship missiles.

CN-235 MPA / HC-144 Ocean Sentry
The CN-235 MPA is a multirole maritime patrol aircraft deployed in maritime surveillance and homeland security missions. It also served as the basis for the HC-144A Ocean Sentry surveillance aircraft used by the US Coast Guard.
The aircraft’s long endurance capability of up to 11 hours and 4,200km range make it one of the best MPAs in the world. Two General Electric GE CT7-9CE turboprop engines, each with a rated power of 1,750shp, ensure superior performance.
The CN-235MPA incorporates a fully integrated tactical system (FITS), which can be integrated with a variety of mission sensors for conducting complex surveillance missions. The aircraft features six hardpoints to carry anti-ship missiles or torpedoes.
ATR 42 MP Surveyor
Alenia Aermacchi developed the maritime patrol aircraft ATR 42 MP Surveyor based on the ATR 42 short-haul regional airliner. The ATR 42MP is currently operated by the Italian Customs Police (Italian Guardia di Finanza), Italian Coast Guard, Nigerian Air Force and Libyan General Security Agency.
The aircraft has a ferry range of 3,741km and can conduct non-stop patrols for up to 11 hours. It integrates the advanced tactical observation system (ATOS) mission management system. The state-of-the-art mission system, along with onboard sensors, enables the aircraft to conduct a variety of missions such as identification and tracking of vessels, maritime and coastal surveillance, search-and-rescue (SAR)and pollution detection missions.
