[2] The aircraft is believed to have first flown in the summer of 1985, with the first post-modification flight taking place on March 5, 1987, and deliveries starting later that year.
[3] Heavily modified from the Ilyushin Il-86, the Il-80 (also referred to as the Il-86VKP) is meant to be used as an airborne command center for Russian officials, including the President, in the event of nuclear war.
[2] Like the E-4B, the aircraft has a dorsal SATCOM canoe, believed to house advanced satellite communications equipment,[2][3] and a trailing wire antenna mounted in the lower aft fuselage for very low frequency (VLF) radio transmission and reception (likely for communication with ballistic missile submarines).
[2][3] When the present upgrades have reached the end of their life, it is expected that a new airborne command post, based on the Ilyushin Il-96-400M commercial aircraft and delivered as the so-called Doomsday plane, will replace them.
[2] They are painted in the current livery of Aeroflot, the Russian state airline; and carry international civilian registrations RA-86147, RA-86148, and RA-86149.
