The Ilyushin Il-78 (Russian: Илью́шин Ил-78; NATO reporting name Midas) is a Soviet four-engined aerial refueling tanker based on the Il-76.

Design and development[edit]

IL-78M from 203rd Guards Air Refuelling Regiment

The Il-72 Tanker was developed, and designed in the Ilyushin Aviation Complex in Russia. The main reason behind the development of the Il-78 was an expansion of the transferable fuel load of an earlier version of tanker, the Il-76.[2]

Compared to the 10,000 kg transferable fuel load of the Il-76, the Il-78 is equipped with two 18,230 lb. tanks in the freight hold. This allows an transferable load of 85,720 kg.[citation needed]

Operational history[edit]

All Russian Air Force Il-78s are now part of the special 203rd "Orlovski" Regiment of aerial tankers, based at Dyagilevo (air base).[citation needed]

Variants[edit]

Il-78
The Il-78 was the original production version with two removable fuselage tanks and a maximum transferable load of 85.72 tonnes (188,540 lb).
Il-78T
Alternative designation for Il-78 due to retention of all cargo handling equipment and convertible freight hold.[3]
Il-78M
The Il-78M entered service in 1987 as a dedicated tanker equipped with three permanent fuselage tanks, a higher gross weight of 210 tons, and no cargo door or cargo handling equipment. The cargo ramp is retained but non-functional. Total fuel capacity is 138 tonnes (303,600 lb), of which 105.7 tonnes (232,540 lb) is transferable.[4]
Il-78M-90A (Il-478)
An upgraded variant based on the Il-76MD-90A. The first prototype was rolled out on 29 November 2017.[5] It had its maiden flight on January 25, 2018 at an Aviastar-SP facility in Ulyanovsk.[6]
Il-78ME
Export version of Il-78M.
Il-78MKI
Customized variant of the Il-78ME for the Indian Air Force. These Uzbekistan-built planes are fitted with Israeli fuel transfer systems and can refuel six-eight Sukhoi Su-30MKIs in one mission.[7][8]
Il-78MP
Multi-role aerial refuelling tanker/transport aircraft, with removable fuel tanks in cargo hold and UPAZ refuelling pods, for the Pakistan Air Force,[9][10] and Chinese Air Force.[11]
