Stroyny was one of the final ships from the renowned Type 7 series. In fact, she hadn’t even undergone the required tests before the start of the war. With only one commissioned engine, Stroyny proceeded to the Ust-Izhora shipyard and engaged the German troops assaulting Leningrad. While the city was under siege, the destroyer’s crew laid down continuous fire on the enemy positions and provided fire support to the Red Army troops breaking through the blockade. According to the official data, Stroyny’s primary armament fired a whole 5,424 rounds on the enemy during the Siege of Leningrad! Due to such intense levels of fire, the ship’s gun liners – the special insertable tubes with cuts that are used in gun barrels – had to be changed twice. After the blockade was broken, Stroyny was stationed in Leningrad, where it remained until the war was over. In the post-war period, the destroyer was converted into a rescue vessel and later on used as a target ship. Stroyny was retired from military service in 1965.
