The Ilyushin Il-38 "Dolphin" (NATO reporting name: May) is a maritime patrol aircraft and anti-submarine warfare aircraft designed in the Soviet Union. It was a development of the Ilyushin Il-18 turboprop transport.
Design and development
The Il-38 is an adaptation of the four-engined turboprop Ilyushin Il-18 for use as a maritime patrol aircraft for the Soviet Navy. It meets a requirement to counter American ballistic missile submarines. The Communist Party Central Committee and the Council of Ministers issued a joint directive on 18 June 1960, calling for a prototype to be ready for trials by the second quarter of 1962. The fuselage, wing, tail unit and engine nacelles were the same as the Il-18 and it had the same powerplant and flightdeck. An aerodynamic prototype of the Il-38 first flew on 28 September 1961, with the first production aircraft following in September 1967. Production continued until 1972, when the longer range and more versatile Tupolev Tu-142 derivative of the Tupolev Tu-95 strategic bomber had entered service.
The airframe is based on the Il-18, with the wings moved forward 3 m (9.84 ft). Unlike the Il-18, only the forward fuselage of the Il-38 is pressurized. The tail contains a MAD, while under the forward fuselage a Berkut ("Golden Eagle") search radar (named "Wet Eye" by NATO) is housed in a bulged radome. There are two internal weapons bays, one forward of the wing, housing sonobuoys and one behind the wing housing weapons.
Some Western sources say 58 were produced; the commander of the ASW squadron at Ostrov has stated Soviet Naval Aviation received 35, of which about thirty remain in service with Russian Naval Aviation. Five were passed to India in 1977/8. In the mid-1990s it seems the Tu-204/Tu-214 airliner won a competition against the Beriev A-40/Be-42 amphibious plane to replace the Il-38 in Russian service, but a lack of funds crippled the project. More recently an A-40 variant seems to be under development to replace the Il-38.
India received three ex-Soviet Naval Aviation Il-38s in 1977, with two more arriving in 1983. Indian modifications included fitting pylons to the fuselage side to carry the Sea Eagle anti-ship missile. The Il-38s of the Indian Navy have been sent back to Russia for upgrades. They will incorporate the new Sea Dragon avionic suite, incorporating a new radar, a Forward looking infrared (FLIR) turret under the nose and an electronic intelligence (ELINT) system housed in a box-like structure mounted on struts above the forward fuselage. Three upgraded aircraft, designated Il-38 SD, have been delivered to the Indian Navy. There are reports of efforts towards adding the capability to fire the Indo-Russian Brahmos cruise missile from this aircraft. Mockups have been displayed with air-launched Brahmos attached to underwing pylons on the Indian Navy aircraft.
One prototype was lost in the early 1970s when it was forced to ditch in the sea.
The Il-38 was operated by units in the Soviet Northern, Pacific and Baltic fleets. In March 1968 a squadron of Il-38s deployed to Cairo in Egypt, flown by Soviet crews but in Egyptian markings, until being withdrawn in 1972. Il-38s continued to deploy overseas through the Cold War, flying from Aden in South Yemen, Asmera in what was then Ethiopia, Libya and Syria. Two Il-38s were attacked on the ground in a commando raid and at least one was destroyed by Eritrean People's Liberation Front fighters in 1984 at Asmera. Following the end of the Cold War and the break-up of the Soviet Union, Il-38s continue in service with the Russian Navy's Arctic and Pacific Fleets.
A tragic mid-air crash occurred on 1 October 2002, during the Indian squadron's silver jubilee celebrations. IN302 and IN304, which were flying parallel to each other, had a mid-air collision above the Dabolim airport in Goa. All twelve aircrew (six aboard each aircraft) were killed and both aircraft were also destroyed.
On December 7, 2010, two Russian Navy Il-38s appeared over the Japan Sea near the Noto Peninsula, interrupting a combined US-Japan Navy drill. The exercises were temporarily halted because of concern that Il-38s might be carrying out surveillance missions on US/Japan naval activities.
