MiG-31BM/Κ Interceptor/Attack aircraft: News

The known MiG-31K´s are a repaired MiG-31DZ (with refueling probe) that includes Kinzhal capability
This is not a modernized MiG-31, because have not the radar of B/BS versions, and for that any of the new capabilities of BM based in that thing
The most visible similarity MiG-31BM and MiG-31K is the periscope over the copkit
However the MiG-31K has not pylons under the wings, and also have not an antenna unther the copkit, just before of the forward landing gear.

All B (with probe) were modernized to BM-type28, last in 2013.Total about 45 in my account for VVS and Navy (remaining from 54 as much received from USSR)
The BS (without probe) are being modernized to BM-type 58 and type 78 since the end of 2013 and it is not clear if will be enough for the current squadrons, completing Perm and perhaps Yelizovo at the end of this year.As much about 90 will be modernized for VVS and Navy , this means probaby about all the available

MiG-31K have the tittle "VKS"in the tail, not VVS. It is still not clear the destination unit of this squadron of MiG-31K.
Anyway there are enough MiG-31DZ stored for raise several squadrons of MiG-31K, in my opinión probably at least one squudron in the two main fleets, as there are not naval Tu-22 since 10 years ago

In addition, in the West, it is claimed that the MiG-31 is morally obsolete, has not been manufactured for a long time and needs to be replaced with a more modern aircraft.  I answer all these critics that the MiG-31 did not fully reveal the potential that its creators, the aircraft designers G.E.  Lozino-Lozinsky and K.K.  Vasilchenko.
Yes, this plane had a difficult fate.  Originally it was planned as a daytime interceptor at high flight speeds - up to 7.000 km / h.  To do this, its body was made of titanium alloys.  In fact, the speed was half as much, as instead of a specially designed engine the plane received the D-30F6, modified based on the civil engine D-30 from the Tu-134.  With a pair of these engines, the maximum speed of the MiG-31 was 3,400 km / h.
Now "ODK-Perm Motors" and "ODK-Star" on the basis of additive technologies were able to restore the production of units and engine assemblies D-30F6 at a new qualitative level.  There is a hope that they will be able to create a "native" engine for the MiG-31, taking into account the prospects of its new combat service.  With the "native" engine flight performance of the aircraft can become much better.

But still the old r-33 instead of r-37.

For the MiG-31BM interceptor, they are developing a modernized version of the radar system, which significantly expands its capabilities. The issue of creating a new modification was discussed during the visit of Deputy Defense Minister Alexei Krivoruchko to JSC "Barrier". This was reported in the department of information and mass communications of the Ministry of Defense of the Russian Federation.

“The deputy head of the defense department supported the modernization of the unique radar complex for MiG-31BM aircraft, which significantly expands its capabilities,” the report said.
