NIZHNY NOVGOROD, November 8 (RIA Novosti) - Russia has successfully conducted test flights of a modernized MiG-31 Foxhound interceptor equipped with improved engines and electronics, a defense company said Wednesday.

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.

1. Can someone explain the differences 'tween the Mig25 vs Mig31?

Looks like the same airframe.

2. Similar, but considerable differences.

Like the MiG-25, it's a really, really fast plane, but not a particularly effective interceptor. Maneuvers like a truck. You can shoot bombers down with it, but it's pretty much defenseless against the F-15, F-16 and F-18, let alone the Raptor.

The MiG-31 has better engines and radar, and uses more titanium and aluminum in a slightly stretched airframe. Both the Su-27 and MiG-29 are more modern and effective, and they're both approaching obsolescence.
