The Russian air force is completing a modification program for its MiG-31 interceptor aircraft to the MiG-31BM standard, the force's commander Col.Gen. Alexander Zelin said on Friday.

"The air force is currently carrying out the vital task of deep modification of the MiG-31 aircraft to MiG-31BM standard. This task is being successfully carried out," he said.

The MiG-31BM is fitted with upgraded avionics and digital datalinks, a new multimode radar, color multi-function cockpit displays, a new, more powerful computer and ability to carry new air-to-air and possibly air-to-surface missiles such as the AS-17 Krypton anti-radar missile.  

Information on display next to a MiG-31BM in 2009 associated the aircraft with air-to-air missiles including the Vympel R-73 (AA-11 Archer), R-77 (AA-12 Adder), and R-33S (upgraded AA-9 Amos) and the K-37M (AA-X-13 Arrow).

The air force is also accepting other new aircraft, including the Su-34 strike aircraft, the forthcoming Su-35, the Yak-130 advanced trainer, and Ka-52 and Mi-28 helicopters, he said.

Manufacturer's tests are also underway on the Sukhoi T-50 fifth generation fighter prototype.
