MiG-25BM Foxbat-F

The recent thread about ARM’s got me wondering about the Foxbat-F.

How many of these birds are in Russian service now and how much longer will they remain in use?

Am I right in saying the only stores they carry are up to four Kh-58’s and a centerline fuel tank if necessary.

What’s a typical mission profile for one of these aircraft?

I know our Russian experts can help me on this stuff.
