Russia is carrying out state trials of the upgraded MiG-31 jet with a fly-by-wire control system.
On Thursday, Deputy Defense Minister Alexei Krivoruchko visited Sokol aviation enterprise’s production facility. He checked the pace of work on repairing and upgrading MiG-31 fighters and also held a meeting on fulfilling the defense procurement plan, TASS reported Thursday.
The management of Sokol informed Krivoruchko that it was possible to switch from the mechanical to the fly-by-wire control system while using the MiG-31.
The MiG-31 can be heavily upgraded to the BM configuration. In the course of the fighter’s upgrade, its onboard equipment will be completely replaced. The combat plane will be also checked for faults to replace corrosion sections that may account for 15-50%. All the wiring and rubber pieces will be completely replaced along with the fighter’s canopy.
The combat efficiency of MiG-31 fighter-interceptors is expected to rise about threefold after their major repairs and upgrades.
The Mikoyan MiG-31 is a supersonic interceptor aircraft that was developed for use by the Soviet Air Forces. The aircraft was designed by the Mikoyan design bureau as a replacement for the earlier MiG-25 "Foxbat"; the MiG-31 is based on and shares design elements with the MiG-25. The MiG-31 is among the fastest combat jets in the world. It continues to be operated by the Russian Air Force and the Kazakhstan Air Force following the end of the Cold and the collapse of the Soviet Union in 1991. The Russian Defence Ministry expects the MiG-31 to remain in service until 2030 or beyond and was confirmed in 2020 when an announcement was made to extend the service lifetime from 2,500 to 3,500 hours on the existing airframes.
Serial production of the MiG-31 began in 1979. The MiG-31 entered operational service with the Soviet Air Defence Forces (PVO) in 1981. It was the world's first aircraft with a phased array radar, and is one of only two aircraft in the world capable of independently firing long-range air-to-air missiles as of 2013.(The other is the Iranian Air Force F-14 Tomcat which uses a domestic version of the long-range AIM-54 Phoenix called the Fakour-90.) The MiG-31BM has a detection range of 282 km (175 mi) for a target with a radar cross-section of 5 square meters.
With the designation Ye-266, a re-engined Ye-155 set new world records. It reached an absolute maximum altitude of 37,650 metres (123,520 feet) in 1977, and set a time to height record of 35,000 metres (115,000 feet) in 4 minutes, 11.78 seconds, both of which were set by the famous MiG test pilot Alexander Fedotov. Pyotr Ostapenko, his deputy, set a time to height record to 30,000 m (98,000 ft) in 3 minutes and 9.8 seconds in 1975.
