> The warship itself was a creation of the USSR, but has more to do with Ukraine's manufacturing prowess than present-day Russia.
It is indeed the product of USSR, which had integrated supply chain and R&D. Very likely some components of it were manufactured in Russia. Ukraine alone would not be able to build and maintain such ship due to budget and resource constraints, but Russia has rebuilt its capabilities in XXI century — their military industrial complex can maintain, upgrade and build such ships. I doubt though they will commission a replacement any time soon, since they are actively building lots of smaller vessels.
