"Sneg" and "Tucha" accompanied a force of seven destroyers in a failed attempt to intercept a German convoy off the Daugava River estuary on 13 July 1941. "Burya", "Sneg" and "Tsiklon" were assigned to the rear guard during the Soviet evacuation of Tallinn and laid mines in the harbor approaches before departing: on their mines (barrage 26-A) was sunk the Finnish coastal defence ship Ilmarinen, during Operation Nordwind, scoring one of the best successes of the Soviet Navy against an enemy major warship. However "Sneg" and "Tsiklon" hit mines themselves in the Axis-laid minefield off Cape Juminda and sink during the night of 28–29 August. "Vikhr" was sunk by German bombers on 21 September and "Taifun" badly damaged two days later. "Purga" was sunk in Lake Ladoga by German bombers on 1 September 1942, but she was raised in 1943 and cannibalized to repair "Vikhr", but she herself was eventually repaired and returned to service in 1944. "Burya" ran into an Axis minefield when attempting to bombard Finnish positions on Suursaari Island and was sunk on 24 August 1942.
