Very interesting Golly. Thank you for your detailed response.
I honestly don't see what's so weird about this class in particular. As per Golly's explanation, the Neustrashimiy is the closest Soviet equivalent of a Western multirole frigate. The closest equivalent I can think of is the Japanese non-AA DDs like the Takatsuki or Asagiri, but even the British Type-23 is a handful of ASROCs from being a dead ringer.
Mostly "SKR" is "frigate", as long as you keep in mind that the Russians were doing <2000t "light frigates" long after everyone else stopped. The Gepard/Tatarstan and Steregushchiy are the current incarnation of that class that, in contrast to Western frigates, is mostly dedicated to coastal warfare.
Anyway, ship classes are so arbitrary and flowing... Add to that the external observer factor and the constant in-class displacement inflation and you end up with Jane's calling the Sovremenniy and Udaloy cruisers in the early 80s, and the Krivak being classified a DDG in the 70s...
If you want confusing, you need to check out the BPKs or "large anti-submarine ships", which were any Soviet ships above SKR that were dedicated to ASW as opposed to surface action. The downside in classification terms was that there wasn't really a limit in displacement, so that ships called either "cruisers" (Kresta,Kara) and "destroyers" (Udaloy, Kashin) in the West would belong to that same mission-based category.
