"Rosoboronexport has signed contracts with the Beriev Aircraft Company, the Perm Motors Group and the Vega concern to provide after sale maintenance to India's airborne early warning (AEW) aircraft," a Rosoboronexport official told reporters at an air show in the Krasnodar Region.
The A-50 Mainstay is a Russian AWACS aircraft based on the Ilyushin Il-76 transport plane. It entered service with the Russian Air Force in 1984, and about 40 aircraft had been produced by 1992.
In 2001 India ordered three A-50EI variant fitted with the Israeli-made Phalcon radar system from Russia. The first aircraft was scheduled to arrive in 2007-08 but has been delayed.
According to various sources, the Russian Air Force has 16-19 A-50 AWACS aircraft.
Russia is currently developing a modernized version of the A-50 plane, which features an improved radar system and more sophisticated and powerful PS-90A engines.
