Ilyushin Il-78 “Midas”
The Soviet Union’s Flying Fuel Station
Built on the Il-76 airlifter, the Il-78 gave Soviet and Russian long-range aviation a modern three-point tanker, and became the standard aerial refueller of India, Pakistan, Algeria and Ukraine.
The Il-78: how the Il-76 airlifter became Russia’s strategic tanker
Through the 1960s and 1970s the Soviet Air Force refuelled its bombers from converted bombers. Myasishchev M-4 and 3M aircraft fitted as tankers supported long-range aviation, and Tu-16 tankers served the medium bombers, but both used a single hose and were growing old. The arrival of new long-range bombers and of probe-equipped tactical aircraft called for something better. Ilyushin’s answer was to adapt its Il-76 four-engined airlifter, which was already in large-scale production at Tashkent in Soviet Uzbekistan. The result, the Il-78, known to NATO as Midas, first flew on 26 June 1983 and entered service in the mid-1980s, giving the Soviet Union a modern jet tanker comparable in role to the American KC-135.
The Il-78 carries its fuel in the Il-76’s wings and in large tanks inside the cargo hold. It passes it through three UPAZ-1 hose-and-drogue pods, one under each outer wing and one on the left side of the rear fuselage, and can refuel up to three aircraft at a time. Fighters use the wing pods; heavy bombers such as the Tu-95 and Tu-160 use the fuselage pod. On the first version the hold tanks could be removed so the aircraft could serve as a transport. The improved Il-78M, which followed in the late 1980s, had fixed tanks and could transfer about 105.7 tonnes of fuel, against 85.7 tonnes on the original.
Only about 45 to 50 Il-78s were built at Tashkent, a small number by Soviet standards. When the Soviet Union broke up, the fleet was split, with Ukraine inheriting a regiment at Uzin. Russia kept the core, about 19 in service by 2019 according to FlightGlobal’s survey, supporting long-range aviation and tactical aircraft. Ukraine sold most of its aircraft abroad, to Algeria and Pakistan, while India bought six new export Il-78MKI tankers in the early 2000s. In January 2018 a modernised Il-78M-90A, built at Ulyanovsk in Russia with new PS-90A engines, made its first flight, meant to give Russia a new generation of tankers without depending on the Uzbek factory.
01The Il-78 abroad: India, Pakistan, Algeria and China
India was the Il-78’s first new-build export customer. It ordered six Il-78MKI tankers, delivered in 2003 and 2004 and based at Agra with No. 78 Squadron. They were specified with refuelling equipment able to serve both Russian-designed fighters such as the Su-30MKI and Western types such as the Mirage 2000 and Jaguar. The fleet has given the Indian Air Force a real long-range capability, but Indian official audits and press reports have repeatedly criticised its availability and support costs, and India has run several competitions for a replacement tanker, while leasing other aircraft for training.
Pakistan bought four Il-78s from Ukraine, delivered between 2009 and 2011. They were refurbished in Ukraine, can also serve as transports, and allow the Pakistan Air Force to refuel its Mirages and JF-17s. Algeria acquired Il-78s from Ukraine at the end of the 1990s to support its Su-24s and later Su-30MKAs. Ukraine retained a small number itself and converted others into freighters. China has been reported to have acquired ex-Ukrainian Il-78s as well, alongside its own tanker developments.
02The Il-78’s new generation: the Il-78M-90A
The break-up of the Soviet Union left Russia with a problem: its heavy transports and tankers were built in Tashkent, now in independent Uzbekistan. Ilyushin moved production of a modernised Il-76, the Il-76MD-90A, to the Aviastar-SP plant at Ulyanovsk, and the Il-78M-90A, also called the Il-478, is its tanker version. It has new PS-90A-76 turbofans of about 35,000 lb of thrust each, a glass cockpit, a strengthened wing and updated refuelling pods.
The first Il-78M-90A flew in January 2018. Russian accounts give it a higher cruise speed and a shorter take-off run than the D-30-powered Il-78, and the new engines are quieter and more efficient. Rosoboronexport also offers an export version, the Il-78MK-90A. Production has been slow, and the older Il-78s and Il-78Ms remain the backbone of Russia’s tanker force. For the Russian Aerospace Forces, the question is less the aircraft itself than numbers: a fleet of a few dozen tankers must support strategic bombers, long-range fighters and transports across eleven time zones.
What makes the Il-78 special
Three UPAZ pods
The Il-78 relies entirely on hose-and-drogue refuelling: there is no flying boom. Three UPAZ-1 pods trail hoses with baskets, two under the wings for tactical aircraft and one on the left rear fuselage, used mainly for heavy aircraft. Fuel flows at about 900 to 2,200 litres a minute depending on the receiver. Because Soviet and Russian aircraft all use probes, one standard serves every receiver, from MiG-31 and Su-34 to Tu-95 and Tu-160 bombers. The trade-off is speed of transfer to large aircraft, which is slower than through a boom.
An airlifter’s strengths
Building on the Il-76 gave the Il-78 the airlifter’s strong high-mounted wing, rugged landing gear for poor runways and four D-30KP turbofans. On the original Il-78 the cargo-hold tanks could be removed, so the same aircraft could carry cargo when not tanking. The Il-78M gave up that flexibility for more fuel. GlobalSecurity notes that the type can also act as a ground refueller, feeding several aircraft at once on an airfield without fuel facilities. The shared airframe also means crews can move between the two types with limited retraining.
Range and offload
The Il-78M can transfer about 105.7 tonnes of fuel in total. The farther it flies, the less it has left to give: published figures for the Il-78M are about 74 tonnes available at 1,000 km from base, 56 tonnes at 2,000 km and 40 tonnes at 3,000 km. That made it well suited to supporting bomber missions far from Russian territory and to refuelling fighters over the vast distances of Russia itself. The figures show why tanker planning is a matter of geometry as much as fuel.

04The Il-78’s operating costs: a thirsty workhorse
The Il-78 shares its engines and most of its systems with the Il-76, which keeps parts and training within a large fleet. The D-30KP turbofans, however, are 1970s technology and are thirsty and noisy by modern standards, and the tanker burns a significant share of its own fuel load on long missions. India’s experience shows the other cost: support from the original manufacturer and its suppliers across several post-Soviet countries has been difficult, and availability has suffered.
The Il-78M-90A’s PS-90A engines are designed to reduce fuel burn and maintenance, but few have been delivered. Real hourly costs for any Il-78 operator are not published, so the figure above is an estimate based on comparable aircraft.

Where the Il-78 flies and flew
The Il-78’s record
The Il-78 is a support aircraft and its operational record is less documented than that of its Western counterparts. It has supported Russian long-range aviation for four decades, including combat missions over Syria, and has given India, Pakistan and Algeria their aerial refuelling capability.
