5 SB-2s had been salvaged from aircraft shot down over Finland during the Winter War by 25 June 1941. They were assigned to LeLv 6 for anti-shipping missions. Most of these had M-103 engines and were, commonly, but incorrectly, called SB-2bis. 3 more were delivered during the late summer of 1941 while one crashed on 2 August. 16 were purchased from Germany, but delivery was very protracted and almost all needed thorough overhaul before they were usuable. All were brought up to the same standard, even the sole SB-2 with M-100 engines. During 1942 they were on anti-submarine patrols, sinking 2 and damaging several others. The first flight of LeLv 6 was converted to the SB-2 by October 1942. Occasionally they were flown on ordinary bombing missions, but not very often. Not one was lost on operations, but 7 were lost through accidents during the Continuation War. They ended their service by hunting German U-boats in the Baltic, not suprisingly without success.
