Many Soviet SBs crashed or force-landed on Finnish soil during the Winter War, with the Finns salvaging as many aircraft as possible, with those in the best condition being sent to "Valtion lentokonetehdas" for possible repair for use by the Finnish air force. By the time of the Continuation War against the Soviet Union, five SBs had been repaired (with a further three added later), being used to equip "Lentolaivue" 6, flying maritime patrol and attack missions. These aircraft were supplemented by a further 16 SBs purchased from Germany, which had captured them during the initial weeks of the invasion of the Soviet Union. These SBs employed the first air-dropped depth charges used in combat. Finland lost seven SBs to accidents during the Continuation War, with none being lost in combat, with Finnish SBs claiming three Soviet submarines and a 4,000 ton merchant ship sunk.
