S-1 was among the first three S-class submarines that were built on the basis of the German-designed submarine E-1, the blueprints of which was sold to the Soviets in 1933. Soviet engineers, working together with the German designers, examined E-1 and made modifications to its design based on their requirements. S-1 was built in Leningrad and included German components.
The submarine carried out two patrols during the Winter War against Finland and was credited with sinking one transport, for a total of, and possibly shot down one Finnish aircraft. On its way back from its second patrol, S-1 was attacked by aircraft and also sustained damage to its hull while having to maneuver through ice in the Baltic Sea. For their actions, the entire crew was awarded the Order of the Red Banner and the captain of S-1 at the time, Alexander Tripolsky, became a Hero of the Soviet Union. It later took part in the naval blockade of Riga when the Soviet Union occupied the Baltic states.
S-1 was undergoing repairs at a shipyard in Liepāja at the start of the Soviet–German War and was scuttled by its crew. The Germans later raised the submarine, since it was still intact, and used it for weapons testing by the Kriegsmarine before it was destroyed in August 1943.
The Srednyaya or S-class submarine (Russian: Средняя|lit=medium), also called the Stalinets class (Russian: Сталинец|lit=follower of Stalin), was an ocean-going diesel electric attack submarine. Its pressure hull had seven compartments, and the Series IX submarine's displacement was 840t while on the surface and 1070t while submerged. It had a length of 77.8m (255.2feet), a beam of 6.4m (21feet), and a draft of 4m (13feet). It had two diesel engines to power it on the surface and two electric motors for when it was submerged, providing and, respectively, to the two propeller shafts. This gave it a speed of 19.5kn on the surface and 9kn while underwater, and the submarine had a range of 9500nmi. Its test depth was 80m (260feet), and as armament it had six 530NaN torpedo tubes, one 100mm deck gun, and one 45mm gun.[1]
S-1 was one of three Series IX boats, along with and . The original design was made by German engineers at NV Ingenieurskantoor voor Scheepsbouw, the Dutch subsidiary of AG Weser, and later boats were modified by the Soviets to take into account the manufacturing capabilities available in the Soviet Union. After examining the German prototype submarine E-1 in 1932 and 1933, Soviet engineers decided to purchase its design for the Soviet Navy with some changes, increasing its size, range, and armament. E-1 became the basis for the first three S-class submarines, the Series IX boats, which were built in Leningrad using some German components.
S-1 was originally called N-1 (yard number 266) and was laid down on 25 December 1934 in Leningrad. The boat was launched on 8 August 1935 and carried out its first voyage to Krondstadt in December 1935. There was a proposal to name the boat Voroshilovets (Russian: Ворошиловец|lit=follower of [[Kliment Voroshilov|Voroshilov]]), though it was not accepted. The submarine was commissioned on 11 September 1936, with Captain 3rd rank Dmitry M. Kosmin in command. On 23 September N-1 was assigned to the 13th Submarine Squadron of the 1st Submarine Brigade in the Red Banner Baltic Fleet. N-1 was renamed S-1 on 20 October 1937.[2] [3]
When the Winter War started with Finland in November 1939, S-1 was stationed in Tallinn with the 13th Submarine Squadron, and was commanded by Captain-lieutenant Alexander Tripolsky. On the first day of the war S-1 was located at the entrance to the Gulf of Finland. When the submarine received the signal "Torch" that signified the start of a war with Finland, it was not understood by its commander because he did not have the document explaining the meaning of signals. On 2 December 1939 S-1 was called back to its base in Tallinn. On the evening of the 3rd, it departed on its first war patrol, in the waters near Rauma on the Gulf of Bothnia. This patrol was mostly uneventful except for the sinking of one transport on 10 December 1939, the German steamer Bolheim. S-1 fired torpedoes at the transport, but they missed, so the submarine surfaced and used its deck gun to sink the vessel. S-1 returned to Tallinn on 12 December.
S-1 left on its second patrol on 22 December 1939 to a position north of the Åland Islands. It ran aground near the island of Märket on the 24th, in the strait of South Kvarken, and was almost rammed by either a Swedish or Finnish vessel. But the submarine managed to move at the last moment and get away. During the patrol S-1 only encountered one convoy and was not able to catch up to them. It began returning to Tallinn on 16 January 1940. On its way back the boat had to maneuver in between pieces of ice and sometimes below the ice. At one point, S-1 was attacked by two Finnish aircraft, and according to the crew they shot down one of them using one of their deck guns. S-1 reached ice-free water on 19 January and returned to Tallinn on the following day. The submarine sustained significant damage from the ice, including to its hull. For this patrol the entire crew of S-1 was awarded the Order of the Red Banner on 7 February 1940 and Captain-lieutenant Tripolsky became a Hero of the Soviet Union. He was made the commander of the 13th Submarine Squadron later that month, and Captain 3rd rank Ivan T. Morskoi was made the new commanding officer of S-1.
In the next few months S-1 was involved in training exercises, before participating in the blockade of Riga in June 1940 when the Soviet Union annexed Latvia and the Baltic states. Afterwards S-1 underwent repairs in Libava (Liepāja), and was reassigned to the 1st Submarine Squadron of the Baltic Fleet. S-1 was in the shipyard being repaired when Operation Barbarossa began on 22 June 1941, and on the 23rd the submarine was scuttled by its crew to prevent its capture by the Germans. The crew then left the city on another submarine, S-3. The Soviet Navy struck S-1 from the naval list on 27 July 1941.
But S-1 was still mostly intact despite being scuttled. It was raised by the Germans and taken to Kiel to be used for weapons testing by the Kriegsmarine, though sources indicate that it was never commissioned into their fleet. S-1 was sunk during one of these tests on 7 August 1943.
