Russia plans to modernize its whole fleet of MiG-31interceptors, which have been in service for 25 years, and extend their service life with the air force until 2015.
"Successful tests confirmed that the MiG-31 has strong potential," the press service of the Perm Engine Company said, adding that the interceptor's unique maneuverability and combat characteristics are largely based on the capabilities of a modernized engine developed by Russian designers.
The interceptor is equipped with two D-30F6 turbofan two-shaft engines with a common afterburner and variable supersonic nozzle, which allow the aircraft to fly at supersonic speeds of up to Mach 2.83.
The modernized interceptor will also feature unique air-to-air missiles capable of hitting targets at ranges exceeding 200 kilometers (125 miles), including aircraft with stealth capabilities, cruise missiles, and supersonic aircraft, Russian Air Force Commander Vladimir Mikhailov earlier said.
"Modernization of the fleet of MiG-31 interceptors will significantly increase the combat capability of air defenses, especially over remote areas of Northern Russia, Siberia and the Far East, where air defense contingents have been sharply reduced since the 1990s," Mikhailov said.
The MiG-31 modernization and overhaul program will be implemented at the Sokol aircraft plant in Nizhny Novgorod, in Central Russia.
Mikhailov said the modernized supersonic interceptor will become a formidable rival to all fifth-generation fighters, due to enhanced radar detection and tracking capabilities, and a wide array of advanced weaponry.
According to various sources, about 500 MiG-31s have been produced since serial production began in 1978, approximately 370 of which remain in service with the Russian Air Force.
