That Zaslon radar tho... Able to track and engage 10 targets out to 200 km out.
-Ultimately, its limiting factor is the ability to only hold 4 R-33 missiles (range of 300 km).
-Or six R-37s (200 km range)

MiG-31 BSM had in-flight refuel, an integral cannon, and an improved radar able to track and engage 24 targets out to 320 km.

So think of it less as an ersatz F-14, and more like an E-3 that is vaugely capable of dogfighting.
