What Soviet destroyers actually did in the war

What did Soviet destroyers do during the Second World War?

They supported some White Sea convoys and operated extensively in the Black Sea, laying mines and providing fire support rather than screening the capital ships for which much of the force had been conceived.

The answer distinguishes actual employment from the fleet doctrine suggested by Soviet construction. Some destroyers joined White Sea convoy work, although minesweepers were more common there. The Black Sea provided the more important destroyer theater, including minelaying and naval gunfire support. Because the intended large surface fleet did not exist, Soviet ships rarely operated in the balanced escort formations their designs anticipated. This makes them a useful example of wartime missions overriding prewar force plans.
