Arctic rush

That looks so cool... rear deck helicopter access, on the lower sides are submersibles and speed boats... on top is a hovercraft with cranes to lower things onto the ice and recover things from the ice or water... the flat open area above the bridge could be used for drones, or even a party...

Very cool.

Chinese ships on the NSR are likely delivering stuff to or from Europe and will likely be welcome... western ships trying to go along the NSR which passes through Russian waters will be about cock swinging and bullshit and will have nothing to do with transporting cargo between the EU and Asia and it is those ships the Russian military will be watching and pointing missiles at.

The work of the testing laboratory, lost after the collapse of the USSR, has been restored in the Arctic

It became known about the next stage of Russia's restoration activities in the Arctic region. The Arctic is gaining more and more strategic weight, and therefore experts predict that it may soon become an arena of open geopolitical confrontation. Already, foreign "partners" are making attempts to question the ownership of the Northern Sea Route to Russia, in fact, offering to ignore the norms of international maritime law.

A new stage in the development of Russian infrastructure in the Arctic is the restoration of the work of a special testing laboratory by TsNIItochmash. We are talking about a special laboratory for testing grenade launcher and small-caliber (cannon) weapons, which operated during the years of the existence of the Soviet Union. The laboratory was truly unique. It worked out options for testing weapons in the harsh Arctic conditions.

The press service of TsNIITOCHMASH reports that the laboratory will be used to test grenade launcher systems and cannon weapons with a caliber of up to 30 mm. The main task is to check the efficiency of the complex at extremely low temperatures - down to minus 60 Celsius. The technology of such tests, fortunately, was not lost after the collapse of the USSR, but the laboratory itself in the early 1990s could not be preserved due to a total lack of funding. Now, restoration will help bring back a unique system and test technology to obtain effective weaponsthat can be used in extreme conditions.

Earlier, the Ministry of Defense of the Russian Federation created several objects in the Arctic region, including the so-called "Arctic Trefoil". It is an autonomous military facility on the Alexandra Land Island, which is used to guard the northern borders of the Russian Federation.

Now, all of the Russian Arctic & NSR is covered by interceptors.

They wont be basing MiG-31BMs there.... they will have MiG-31Ks there if they have any smarts... that far away from anywhere there wont be many enemy aircraft located in that region, except on aircraft carriers and the best and quickest way to defeat a whole US or French or UK carriers worth of fighters is with a single Kinzhal or Zircon missile...

With inflight refuelling the flight radius of a MiG-31K could be 3,000km... it could fly with the inflight refuelling tanker to a location 2,300km short of the target and then accelerate up to top speed and altitude and launch a 2,000km range Kinzhal and then turn around and fly with the tanker all the way home at high subsonic speeds so it could take out ships within 5,000km of the air base in a matter of hours or minutes...

Intercept and do what?

Putting some R-73s on a MiG-31K would achieve the same result.

A MiG-31BM escort might be useful but most of the time it will be Kinzhal that is what is needed.

BTW jamming a ship operating in iceberg prone waters would be a pretty dumb thing to do... it would make more sense to send a ship to get it to leave, but the west does not really have much in the way of ice breaking ships to operate there on their own in the first place.
