Developed from Mikoyan-Gurevich MiG-25

The Mikoyan MiG-31 (Russian: Микоян МиГ-31; NATO reporting name: Foxhound) is a supersonic interceptor aircraft developed to replace the MiG-25 "Foxbat". The MiG-31 was designed by the Mikoyan design bureau based on the MiG-25.[4] It is one of the fastest combat jets in the world.[5]

Development[edit]

The MiG-25, despite Western panic about its tremendous performance, made substantial design sacrifices in capability for the sake of achieving high speed, altitude, and rate of climb. It lacked maneuverability at interception speeds and was difficult to fly at low altitudes. The MiG-25's speed was limited to Mach 2.83 in operations, but it could reach a maximum speed of Mach 3.2 or more with the risk of damaging the engines beyond repair.[6][7]

Development of the MiG-25's replacement began with the Ye-155MP (Russian: Е-155МП) prototype which first flew on 16 September 1975.[8] Although it bore a superficial resemblance to a stretched MiG-25 with a longer fuselage for the radar operator cockpit, it was in many respects a new design. The MiG-25 used 80% nickel steel in its structure to allow welding.[9]

The most important development was introducing an advanced radar capable of both look-up and look-down/shoot-down engagement (locating targets above and below the aircraft), as well as multiple target tracking. This finally gave the Soviet Union an interceptor able to engage the most likely Western intruders (low flying cruise missiles and bombers) at long range.[10]

Like its MiG-25 predecessor, the MiG-31 was surrounded by early speculation and misinformation concerning its design and abilities. The West learned of the new interceptor from Lieutenant Viktor Belenko, a pilot who defected to Japan in 1976 with his MiG-25P. Belenko described an upcoming "Super Foxbat" with two seats and an ability to intercept cruise missiles. According to his testimony, the new interceptor was to have air intakes similar to the Mikoyan-Gurevich MiG-23, which the MiG-31 does not have, at least not in production variants.

The MiG-31 aircraft can be used effectively in conditions of active opposition from the opponents: the use of active and passive radar jammers and thermal launch false targets. A group, consisting of 4 interceptor MiG-31 is able to control the air space along a front the total length of 800–900 km,[10] because of its highest detection range of 200 km in distance (radius) and the typical width of detection along the front of 225 km.[11]

Production of the MiG-31 ended in 1994.[12]

Upgrades and replacement[edit]

Some upgrade programs have found their way in the MiG-31 fleet, like the MiG-31BM multirole version with upgraded avionics, new multimode radar, hands-on-throttle-and-stick (HOTAS) controls, liquid crystal (LCD) color multi-function displays (MFDs), ability to carry the R-77 missile and various Russian air-to-ground missiles (AGMs) such as the Kh-31 anti-radiation missile (ARM), a new and more powerful computer, and digital data links. A project to upgrade the Russian MiG-31 fleet to the MiG-31BM standard was begun in 2010;[13] 100 aircraft are to be upgraded to MiG-31BM standard by 2020.[14][15] It has been claimed by Russian Federation Defence Ministry chief Colonel Yuri Balyko, that the upgrade will increase the combat effectiveness of the aircraft several times over.[16] 18 MIG-31BMs were delivered in 2014.[17]

Russia hopes to field a replacement for the MiG-31 by 2020, with all aircraft retired by 2028. Development of a new aircraft, designated MiG-41, had started by April 2013. Development of a new interceptor is favored over restarting MiG-31 production.[18] In March 2014, Russian test pilot Anatoly Kvochur said that work has begun on a Mach 4[dubious ] MiG-41 based on the MiG-31.[19][20] Development on the MiG-31 replacement is to begin in 2017, with the first aircraft to be delivered in 2020, and to enter service in 2025.[21]

Design[edit]

Like the MiG-25, MiG-31 is a large twin-engine aircraft with side-mounted air intake ramps, a shoulder-mounted wing with an aspect ratio of 2.94, and twin vertical tailfins. Unlike the MiG-25, it has two seats, with the rear occupied by a dedicated weapon systems officer.[22]

Airframe and engines[edit]

The wings and airframe of the MiG-31 are stronger than those of the MiG-25, permitting supersonic flight at low altitudes. Its D30-F6 jet engines, each rated at 152 kN thrust, allow a maximum speed of Mach 1.23 at low altitude. High-altitude speed is temperature-redlined to Mach 2.83 – the thrust-to-drag ratio is sufficient for speeds in excess of Mach 3, but such speeds pose unacceptable hazards to engine and airframe life in routine use.[6]

MiG-31 is limited to only 5 g at supersonic speeds.[6] At combat weight, its wing loading is marginal and its thrust-to-weight ratio is favorable. However, it is not designed for close combat or rapid turning.[6]

Electronics suite[edit]

The MiG-31 was the world's first operational fighter with a passive electronically scanned array radar (PESA), the Zaslon S-800. Its maximum range against fighter-sized targets is approximately 200 km (125 mi), and it can track up to 10 targets and simultaneously attack four of them with its Vympel R-33 missiles. The radar is matched with an infra-red search and track (IRST) system in a retractable undernose fairing.[6]

The A-50 AEW aircraft and MiG-31 can automatically exchange aerial and terrestrial radar target designation.[23]

Radars[edit]

Adopted in 1981 RP-31 N007 backstop (Russian -Zaslon).[24]

  • the range of detection of air targets: 200 km (for the purpose of a radar cross-section of 19 m2 on a collision angle with probability 0.5)
  • target detection distance with radar cross-section of 3 m2 in the rear within 35 km with a probability of 0.5 ([25][26])
  • number of detected targets: 24 (was originally 10[27])
  • number of targets for attack: 6 (was originally 4[27][28])
  • range of automatic tracking: 120 km
  • detection of thermal goals: 56 km
  • Has great opportunities for the detection of cruise missiles and other targets against the background of the earth's surface[27]
  • The MiG-31 was the world's only serial fighter equipped with phased array radar until 2000,[29][30] when the Mitsubishi F-2 entered service with state of the art J/APG-1 active phased array radar.

The basic differences between other versions and the МiG-31BM:[31]

The onboard radar complex of the MiG-31BM can track 24 airborne targets at one time, 6 of which can be simultaneously attacked by R-33S missiles.

Modernized variants of the aircraft can be equipped with anti-radiation missiles Kh-31, Kh-25MR or MPU (up to six units), anti-ship Kh-31A (up to six), air-to-surface class missiles Kh-29 and Kh-59 (up to three) or Kh-59M (up to two units), up to six precision bombs KAB-1500 or eight KAB-500 with television or laser-guidance. Maximum mass of payload is 9000 kg.[citation needed]

The MiG-31M, MiG-31D, and MiG-31BM standard aircraft have an upgraded Zaslon-M radar, with larger antenna and greater detection range (said to be 400 km (250 mi) against AWACS-size targets) and the ability to attack multiple targets — air and ground — simultaneously. The Zaslon-M has a 1.4 m diameter (larger) antenna, with 50% to 100% better performance than Zaslon. In April 1994 it was used with an R-37 to hit a target at 300 km distance.[24] It has a search range of 400 km for a 19/20 m2 RCS target and can track 24 targets at once, engaging six[32][33] (282 km for 5 m2[34]). Target speed increased from 5 Mach to 6 Mach, improving possibility of firing through the land.[24] The MiG-31 is one of only a few aircraft able to intercept and destroy cruise missiles flying at extremely low heights.[24][35][36]

Cockpit[edit]

The aircraft is a two-seater with the rear seat occupant controlling the radar. Although cockpit controls are duplicated across cockpits, it is normal for the aircraft to be flown only from the front seat. The pilot flies the aircraft by means of a centre stick and left hand throttles. The rear cockpit has only two small vision ports on the sides of the canopy. It is argued that the presence of the WSO (Weapon Systems Operator) in the rear cockpit improves aircraft effectiveness since the WSO is entirely dedicated to radar operations and weapons deployment. This decreases the workload of the pilot and increases efficiency. Both cockpits are fitted with zero/zero ejection seats which allow the crew to eject at any altitude and airspeed.[6]

Armament[edit]

MiG-31 armed with R-33 missiles

The MiG-31's main armament is four R-33 air-to-air missiles (NATO codename AA-9 'Amos') carried under the belly. The R-33 is the Russian equivalent of the U.S. Navy's AIM-54 Phoenix.

Unlike the MiG-25, the MiG-31 has an internal cannon, a six-barrel, 23 mm GSh-6-23 with 800 rounds of ammunition, mounted above the starboard main landing gear bay. The GSh-6-23 has a claimed rate of fire of over 10,000 rounds per minute. However, due to the loss of two Su-24s because of premature shell detonation in 1983, and problems with gun usage (such as system failures), use of the GSh-6-23 was stopped by a decision of the Soviet AF Command. The aircraft in the Russian AF were flying with fully operational guns, but without ammunition in January 2009.[37]

Operational history[edit]

Two MiG-31s flying in formation

Serial production of ordinary MIG -31 started in 1979.[38] The MiG-31 entered operational service with the Soviet Air Defence Forces (PVO) in 1981[39] It was the only Soviet fighter capable of intercepting the Lockheed SR-71 Blackbird, and did so several times starting in 1986.[22] Not only the world's first aircraft with a phased array radar, but the only capable of independently firing long-range missiles as of 2014.[40][40][41][42] For the MiG-31BM detection range of 282 km for the purpose of 5 square meters,[43] and 189 km for stealth objectives.[44]

With the designation Ye-266, a re-engined Ye-155 shattered world records. It reached an absolute maximum altitude of 123,524 ft, or 37,650 m, and set a time to height record of 35,000 m in 4 minutes, 11.78 seconds, both of which were set by test pilot Alexander Fedotov. Ostapenko, his deputy, set a record of 30,000 m in 3 minutes, 9.8 seconds.[45]

Following the disintegration of the USSR in 1991 the budget for spares and maintenance collapsed, leaving many squadrons unable to maintain their aircraft. The MIG-31 AOG desk was created to address this problem.[citation needed]

Export[edit]

Syria ordered eight MiG-31E aircraft in 2007 for Syrian Air Force.[46][47] However, the order has been suspended in May 2009 reportedly either due to Israeli pressure or lack of Syrian funds.[48]

Variants[edit]

MiG-31B[edit]

A new version of the MiG-31 with upgraded avionics and in-flight refueling, the MiG-31B, was introduced in 1990. Its development was the result of the Soviet discovery that Phazotron radar division engineer Adolf Tolkachev had sold information on advanced radars to the West. A new version of the compromised radar was hastily developed.[49] Many earlier MiG-31s were upgraded to the new MiG-31BS standard, but not equipped with in-flight refueling system.[50]

MiG-31M[edit]

Development of a more comprehensive advanced version, the MiG-31M, began in 1984 and first flew in 1985, but the dissolution of the Soviet Union prevented it from entering full production. The MiG-31M standard adds some additional features.[51]

MiG-31BM[edit]

The upgraded MiG-31BМ maximum range of detection of air targets increased to 320 km, automatic tracking accepted up to ten goals, and the latest complexes can track up to 24 targets and simultaneously can attack up to 6 targets. On-Board computer Argon-K selects the four most important, which simultaneously are engaged by four air-to-air long-range R-33S missiles. Thermal search is interfaced with radar and is designed for passive review of the airspace, and for the issuance of R-40TD and R-60 TGS missiles targeting.[citation needed]

The basic differences between earlier versions and the МiG-31BM[52] (1998):[53] really this is a small AWACS airplane. Onboard equipment provides interaction with anti-aircraft missile defense complexes and the use of aircraft as an air command post to coordinate the actions of other types of fighters.[11]

The flight-navigation equipment of the MiG-31 includes a system of automatic control system SAU-155МP and sighting-navigation complex KN-25 with two inertial systems and IP-1-72A with digital computer «Maneuver», electronic range navigation system «Radical» NP (312) or A-331, electronic system of the far - navigation A-723. Distant radio navigation is carried out by means of two systems: «tropic» (similar to the system of «Laurent») and «Route» (similar to the system of «omega»)[clarification needed].[54]

The MiG-31 is equipped with sr-you ECM radar and infrared ranges.[29] Interceptor MiG-31 is capable of performing combat tasks.

The MiG-31 was equipped with RK-RLDN and APD-518[3] digital secure datalinks. The RK-RLDN datalink is for communication with ground control centers. The APD-518 datalink enables a flight of four MiG-31 to automatically exchange radar-generated data within 200[55] km (124 mi) from each other. It also enables other aircraft with less sophisticated avionics,[56] such as MiG-23,25,29/Su - 15,27[11] to be directed to targets spotted by MiG-31 (a maximum of 4 (long-range) for each MiG-31 aircraft). Similarly[57] complex S - 300 aircraft with a group of APD-518 can: share data obtained by various radars from different directions (active or passive scanning radiation) and summarize the data. That is, the target can be detected by passively (through noise posed to protect themselves / active search radar (target)) and (or) the active simultaneously from many different directions (active search radar MiG-31). And everyone aircraft has APD-518 will have exact data, even if it is not involved in the search.[3][24][38]

  • arming - 4 long-range missiles + 4 short-range/medium-range missiles (including R-77 medium-range).[29]
  • interacting with ground-based automated digital control system (ACS «Rubezh» Operating radius of 2000 km, can control multiple groups of planes), operating modes remote aiming, semi-automated actions (coordinate support), singly, and also: to direct on the target missiles launched from the other aircraft.
  • Digital immune system provides the automatic exchange of tactical information in a group of four interceptors, remote one from another at a distance of 200 km and aiming at the target group of fighters with less-powerful avionics (in this case the aircraft performs the role of guidance point or repeater).[11]

Notable accidents[edit]

On 6 September 2011, a MiG-31 crashed near Bolgary village, Perm region, Russia.[62] The aircraft crashed shortly after takeoff, killing both pilots. Another, non-fatal crash occurred in 2010. The entire fleet was grounded pending an investigation.[63]

During the night of 23 April 2013, a Kazakhstan Air Force MiG-31 crashed during a training flight near the village of Prostornoye in the Karaganda Region of Kazakhstan, killing the pilot and injuring the navigator. The plane crashed due to technical failure. The same plane underwent a major overhaul at a plant in Rzhev, northwest Russia in December 2012.[64]

On 4 September 2014, a MiG-31 crashed during exercises at a distance of 25 kilometres from the city of Armavir.[65]
