Shch-307 (Russian: Щ-307) was a Series V-bis-2 {{sclass|Shchuka|submarine}} built for the Soviet Navy during the 1930s with the name of {{lang|ru|Treska}}. Renamed Shch-307 while under construction in 1934, she was completed the following year. The boat was assigned to the Baltic Fleet and participated in the defense of the Soviet Union after the Axis powers invaded in June 1941 (Operation Barbarossa). The ship played a minor role during the evacuation of Tallinn, Estonia, in August. Shch-307 made only four war patrols during the war, but sank a German submarine in 1941. After the war, the boat was decommissioned in 1948, renamed PZS-5 and converted into a floating charging station the following year. She was stricken from the navy list in 1957 and subsequently scrapped, although her conning tower was preserved as a memorial.
Background and decription
File:Shadowgraph Schuka class V-bis-2 series submarine.svg
The Series V-bis-2 Shchuka-class submarines were improved versions of the Series V-bis boats placed into production because Soviet shipyards were having difficulties integrating new German technology. The boats displaced {{convert|591|t|LT|sp=us|lk=on}} surfaced and {{cvt|708|t|LT}} submerged. They had an overall length of {{convert|58.75|m|ft|sp=us|0}}, a beam of {{convert|6.2|m|ftin|sp=us}}, and a mean draft of {{convert|4.22|m|ft|0|sp=us}}. The boats had a diving depth of {{cvt|75|m}}. Their crew numbered 39 officers and crewmen.Budzbon, Radziemski & Twardowski, p. 160
For surface running, the Series V-bis-2 boats were powered by a pair of 38V-8 diesel engines, one per propeller shaft. The engines produced a total of {{convert|1370|PS|kW|lk=on|0|sp=us}}, enough to give them a speed of {{convert|13.5|kn|lk=in}} due to better streamlining of the hull. When submerged each shaft was driven by a {{convert|400|PS|kW|0|adj=on|sp=us}} PGV8 electric motor for {{convert|8|kn}}. The boats had a surface endurance of {{convert|5100|nmi|lk=in}} at {{convert|8.35|kn}}; and {{cvt|104|nmi}} at {{convert|2.74|kn}} submerged.
The Series V-bis-2 boats were armed with six {{convert|533|mm|in|0|adj=on|sp=us}} torpedo tubes. Four of these were in the bow and the others were in the stern. They carried four reloads for the bow tubes. The submarines were also equipped with a pair of 45 mm anti-aircraft gun (21-K) deck guns fore and aft on the conning tower.Polmar & Noot, pp. 254–255
Construction and career
Shch-307 was laid down by the Baltic Works in Leningrad on 6 November 1933 with the name of Treska. She was launched on 1 August 1934 and renamed Shch-307 on 15 September. The submarine was commissioned on 4 August 1935 into the Baltic Fleet. The boat was refitted in 1938–1939 and played no part in the 1939–1940 Winter War with Finland because she was conducting post-refit training.Budzbon, Radziemski & Twardowski, pp. 160, 162 The submarine played a small role during Operation Barbarossa. During the Baltic Sea campaign, Shch-307 sank the {{GS|U-144}} off Dagö Island (now Hiiumaa, Estonia) on 10 August. She evacuated from Tallinn to Kronstadt on 28–30 August.Rohwer, pp. 85, 90
The boat penetrated the Axis mine barrage defending the exit from the Gulf of Finland in September 1942 and sank a small merchant ship in the Åland Sea during her second war patrol in October. She made her next patrol in October 1944, after Estonia had been liberated and the Axis minefields cleared. While patrolling in the vicinity of Vindava, Latvia, Shch-307 made six unsuccessful attacks on Axis shipping. During her next patrol in January 1945, the submarine missed a German patrol boat, but sank a small steamship.Rohwer, pp. 197, 199, 209, 361, 385
After the war, she was disarmed on 23 April 1948 and turned into a floating charging station renamed PZS-5 in 1949. The boat was stricken on 8 April 1957 and subsequently broken up; her conning tower was preserved as a memorial in Liepāja, Latvia. When that country became independent, the conning tower was moved to Moscow in 1994.Budzbon, Radziemski & Twardowski, p. 162
