Most important battles involving 1125 class in Baltic Sea:

28 August 1941.
Soviet gunboats BK-213 and BK-214 raided the Finnish coast and intercepted a convoy of Finnish motorboats towing pontoons. Soviet commanders decided to not open gunfire, to not alert Finnish patrol boats, and the pair started a series of "taran" (ramming) attacks. In brief time, 4 Finnish motorboats were sunk alongside 2 pontoons, while other 2 pontoons were destroyed. Finnish sources confirm such losses (Soviets actually claimed a bit more: 10 targets sunk), and they suffered 3 killed and 4 wounded. The pontoons were empty yet this successful attack was a good result, but due the war situation similar raids were not repeated.

13 August 1944.
Soviet gunboat BK-213 took part in another successful battle: with BK-322, they clashed against a group of 4 German auxiliary minesweepers into Peipus Lake. During the fight, the Soviet armored boats managed to split the enemy: the German KM-19 managed to escape even if she was damaged with 3 wounded, however KM-08 was surrounded by the BKs. The German boat suffered direct hits from the Soviet gunfire, finally BK-213 accomplished another "taran" (ramming) attack and the KM-08 was wrecked against the shore. Of the crew of 11 Germans, 2 managed to hide themselves and were later recovered by enemy, 5 died, 4 were captured (2 of them died for wounds). BK-213 suffered little damages with 2 wounded. Germans later further destroyed the wreck of KM-08 with an air raid to prevent the recovering by Soviets.

17 April 1945.
During the night between 16 and 17 April, a Soviet group of armored boats (BK-200, BK-201, BK-202, BK-204, BK-205, BK-206, BK-212, BK-213 and BK-214) attacked a German convoy of barges and armed barges that was sailing away from Pillau. Sadly German documents of this time of war are absents: Soviets claimed to have sunk 2 armed barges and 2 other transport barges, but these victories can't be confirmed. It has been proposed that the German armed barge PiLb-554 (reported to have been sunk "due mine" that night and close that location) was actually sunk during the battle.

26 April 1945.
Soviet gunboats of 1125 type clashed against at least 3 German armed barges of unclear class. Sadly there is a lack of documents about this battle, Soviets claimed to have destroyed two enemy targets. This event still have to be researched.


Most important battles involving 1125 class in Black Sea:

18 August 1943.
In Azov Sea. The German auxiliary gunboats MAL-1 and MAL-2 intercepted in open sea the small Soviet gunboats BK-123 and BK-133 (both of 1125 class). Germans fully exploited the better range of their 88mm guns and the more stable aiming (the soviet gunboat's forward turret wasn't a stable firing gun for open sea). Both the soviet gunboats where hit and sunk without effects on Germans from Soviet fire. 4 prisoners were captured.

30 August 1943.
Soviets made a raid on the Bay of Taganrog. The small gunboats BK-311 and BK-313 landed a team and engaged with the auxiliary gunboat MAL-1: they distanced and the German gunboat engaged at longer range the small gunboat BK-312 (class 1125) and BK-122 (class 1124). As happened on 18 August, the MAL exploited her longer range of the guns and managed to sunk both the gunboats without suffer damage or losses: 7 soviet sailors were captured. Later however a group of soviet aircrafts managed to strafe the group with the same gunboat MAL-1 that joined MAL-2, MAL-3, MAL-4, MAL-9 and the auxiliary minesweepers R-30 and RA-52 escorting 5 barges: some damages were caused (unclear on which units), with 3 killed and a number of wounded.


Most important battles involving S-40 class:

7 November 1943.
In Black Sea, during the support for Kerch-Eltigen operations, the gunboats BK-81 and BK-323 (both of S-40 class) clashed against German armed MFP crafts. During the battle BK-323 suffered light damages but so did the German F-316, F-446 and F-578. Thanks this clash, German MFPs sunk no transport target that night.
