MiG-25 Foxbat flew in a recon role with the IAF for over two decades

The MiG-25 Foxbat was initially designed as a high-speed pure interceptor to combat the developing XB-70 Valkyrie American bomber capable of Mach 3. Though the Valkyrie never materialized for US war planners, the MiG-25 was kept in production and became one of the fastest aircraft in the world. The MiG-25 (NATO codename of "Foxbat") held various altitude and speed records when it was first unveiled. The aircraft was capable of near Mach 3 speeds at Mach 2.8 and could hit altitudes well above 120,000 feet. The system was powered by two Tumansky turbojet engines that produced a combined thrust of nearly 50,000lbs without any onboard weapons as the Mig-29RB variant in Indian Service.

Design and Development

Overflights by American U-2s in the late 1950s revealed a need for higher altitude interceptor aircraft for Soviet Union. In 1960, Soviet intelligence learned of the US's development of the high altitude, Mach 3 A-12 reconnaissance aircraft. A variety of roles were considered for the prospective aircraft, including cruise missile carriers and even a small five to seven-passenger supersonic transport, but the main objective was a high-altitude reconnaissance aircraft and heavy interceptor. The Mikoyan-Gurevich OKB accepted the assignment effective 10 March 1961, carrying the bureau designation "Ye-155" (or "Е-155").

Far from being the consummate dogfighter, the MiG-25 was designed as a stand-off interceptor. The aircraft was assisted by ground control radar until its system radar could actively track the target. From there, the Foxbat had the capability of reaching high altitudes in a matter of minutes. The system could then attack an air target from up to 50 miles away and engage it with its 20 foot long air-to-air Acrid missiles. Flying at such high speeds at altitude required the body of the aircraft to be made of nickel and titanium due to intense heat buildup. The aircraft was also a fuel guzzler and could only achieve Mach 3 flight speed for if only a little while. None the less, the system was potent as the interceptor it was designed for. A further development of the air-to-air Foxbat came in the form of the MiG-25PD which was a long-range, high-speed, high-altitude reconnaissance aircraft. This system would be featured greatly throughout the Cold War as the Americans unveiled their Mach 3-capable high-speed, high-altitude Lockheed SR-71 Blackbird spyplane. From there, the system would be fielded throughout the fronts of the Soviet Union. The Foxbat eventually made it into export hands, in particular with Egyptian forces against Israel. Iraq also fielded the type in the first Persian Gulf War against coalition forces, accounting for the single Iraqi aerial victory over a United States Navy F/A-18 Hornet. From there, the system served a limited, albeit important, role for the Soviet Union and its satellite states.  India finally Purchased the foxbat in 80s.

Aircraft design phase

Because of the thermal stresses incurred in flight above Mach 2, Mikoyan-Gurevich OKB constructed the MiG-25 largely from nickel alloy ("Inconel"), but used a small amount of titanium and aluminum alloys in areas particularly susceptible to high aerodynamic drag. The steel components of the MiG-25 were formed by a combination of spot-welding, automatic machine welding and hand arc welding methods. Initially there was concern that jolts from landing would cause the metal welds to crack but this proved not to be the case, and any cracks that did develop in service were easily welded in the field.

Although intended for intercepting or threatening high-altitude, high-speed aircraft the MiG-25's maneuverability, range, and close combat potential were extremely limited. Even its high speed was problematic: although sufficient thrust was available to reach Mach 3.2, a limit of Mach 2.8 had to be imposed as the turbines tended to overspeed and overheat at higher speeds, possibly damaging them beyond repair. Inaccurate intelligence analyses caused the West to initially believe the MiG-25 was an agile air-combat fighter rather than an interceptor. In response, the United States started a new program which resulted in the F-15 Eagle

Design Description:

A true understanding of the strengths and failings of the MiG-25 by the West came on 6 September 1976, when a PVO pilot, Lt. Viktor Belenko, defected to the West, landing his MiG-25P at Hakodate Airport in Japan. It was carefully dismantled and analyzed by the Foreign Technology Division (now the National Air and Space Intelligence Center) of the United States Air Force, at the Wright-Patterson Air Force Base. After 67 days, the aircraft was returned to the Soviets in pieces. The analysis showed some surprising facts:

Operational History

India

Entirely unarmed — the IAF chose the reconnaissance variant, not the interceptor — and with no modern countermeasures against surface-launched missiles, the Foxbat’s only defence lied in its speed and cruising altitude. India operated MiG-25s in a reconnaisance role. A big mammoth of an aircraft, powered by huge twin engines, flying three times the speed of sound and over three times higher than the maximum altitude allowed to civil airliners, the MiG-25 was the perfect monster the Indian government — and especially then Air Chief Idris Latif — needed to gun up IAF’s virtually non-existent reconnaissance capability in the late 1970s to spy on Pakistan and China.

Not much is known about the operational history of foxbat since itś mission and its technologies were both classified except the infamous incident when one IAF pilot broke sound barrier over pakistani airspace shattering windows and creating a loud booming sound that was heard for miles.

Abroad

• Before entering operational service, four MiG-25Rs were temporarily in service with Egyptian Air Force in 1971 under the cover designation of "X-500". All four had EAF markings. They flew over Sinai in pairs roughly 4 times. On 6 November 1971, an Egyptian MiG-25 flying at Mach 2.5 was met by Israeli F-4Es and fired upon unsuccessfully.The Israeli Air Force found it impossible to intercept them, even though Israeli intelligence generally knew when the overflights were scheduled. The MiG-25Rs went back home in 1972, though reconnaissance Foxbats were sent back to Egypt in October 1973, after the Yom Kippur War, and remained there into 1974. A MiG-25 was tracked flying over Sinai at Mach 3.2 during this period. The MiG-25 oversped its engines which led to their destruction.The Israeli Air Force did not have the capability to intercept MiG-25s until it received the F-15 Eagle.
• Col. Aleksandr V. Drobyshevsky, confirmed that at least one Soviet pilot, in the USSR's MiG-25 "Foxbat" aircraft, flew recon missions from Egypt into Israel in 1967, just prior to the Six Day War.
• During the Persian Gulf War, a US Navy F/A-18 piloted by Lt Cdr Scott Speicher was shot down on the first night of the war by air-to-air missile fired most likely by a MiG-25. The kill was reportedly made with a R-40DT missile fired from a MiG-25PDS flown by Lt. Zuhair Dawood of the 84th squadron of the IrAF.

• In another incident, an Iraqi MiG-25PD, after eluding eight U.S. Air Force F-15s, fired three missiles at EF-111 Raven electronic warfare aircraft, forcing them to abort their mission. This may have led to the later loss of an F-15 to surface-to-air missiles, due to the lack of electronic jamming
• In yet another incident, two MiG-25s approached a pair of F-15s, fired missiles (which were evaded by the F-15s), and then outran the American fighters. Two more F-15s joined the pursuit, and a total of ten air-to-air missiles were fired at the MiG-25s, though none reached them. According to the same sources, at least one F-111 was also forced to abort its mission by a MiG-25 on the first 24 hours of hostilities, during an air raid over Tikrit.

Retirement

The Phasing out ceremony of the MiG-25R Foxbat "Garuda" was held on May 1st, 2006 at Air Force Station Bareilly. No.35 Squadron, which operates the MiG-25 undertook a simple ceremony which was presided by the Chief of Air Staff, Air Chief Marshal S.P.Tyagi. The ceremony showcased a flypast by a MiG-25 flown by Wg Cdr Sanjiv Talyan. The aircraft landed and taxied to the apron in front of the dias, where Wg Cdr Talyan got down, marched upto the CAS in his flight suit and handed over the Form 700 of the sortie to him, signifying the last operational sortie in the IAF. Two MiG-25s were on display at this ceremony, one which was used in the flypast, the other which was towed in front of the audience and later parked near the hangar. Various items related to the Foxbat, like its massive Tumansky engine and jet nozzle, its Photo-Recce Cameras as well as some of its older photographs were on display. Several former COs of No.102 Squadron attended the function. The IAF has four flyable MiG-25s which will be flown to various destinations around India for preservation. There are another two airframes which will also be put up for preservation at a later date.

Replacement

There is no direct replacement for MiG-25 underway in Indian Air Force. Initial speculation about acquiring MiG-31 Foxhound existed but no recent reports to suggest the same have surfaced. It is suugested that vast improvements in Indian satellite and UAV based reconnaisance has made this category largely irrelevant for IndianAir Force.
