Il-78

  • Performance

    General Data

    The Il-78 aircraft has been developed on the basis of the Il-76MD and is designed to refuel in the air long-range aircraft and frontline aviation during daytime and nighttime, andin conditions of poor visibility, in order to widen their operational range. TheIl-78 may be used for transporting fuel to the maneuvering airfield and refueling aircrafton the ground.

    The cargo compartment contains two fuel tanks. With the help of three unified suspended-type refueling devices (UPAZ) installed under outer wing panels and in the aft part of the fuselage, the transmission of fuel from fuselage tanks and wing boxes is possible.

    If necessary, the aircraftcan be refitted under field conditions as a transportation plane for carrying military personnel, equipment, cargoand ill/wounded people.
