Type UC II minelaying submarines were used by the Imperial German Navy during World War I. They displaced 417 tons, carried guns, 7 torpedoes and up to 18 mines. The ships were double-hulled with improved range and seakeeping compared to the UC I type.
The Type UC I coastal submarines were a class of small minelaying U-boats built in Germany during the early part of World War I. They were the first operational minelaying submarines in the world. A total of fifteen boats were built. The class is sometimes also referred to as the UC-1 class after SM UC-1, the class leader. The Italian X-class submarine was a reverse-engineered and modified type of the UC-1-class.
SM UC-8 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy during World War I. The U-boat had been ordered by November 1914 and was launched on 6 July 1915. She was commissioned into the German Imperial Navy on 5 July 1915 as SM UC-8. Mines laid by UC-8 in her one patrol are not known to have sunk any ships. UC-8 ran aground on the Dutch coast near Terschelling on 4 November 1915. Interned by the Dutch, UC-8 was purchased and commissioned into the Dutch Navy as M-1. The submarine was broken up in 1932.
SM UC-12 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy during World War I.
SM UC-15 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 23 November 1914, laid down on 28 January 1915, and was launched on 19 May 1915. She was commissioned into the German Imperial Navy on 28 June 1915 as SM UC-15. Mines laid by UC-15 during her eight patrols are credited with sinking 3 ships. UC-15 disappeared in November 1916.
Two submarines of Germany have borne the name UC-2:
SM UC-16 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 29 August 1915 and was launched on 1 February 1916. She was commissioned into the German Imperial Navy on 18 June 1916 as SM UC-16. In 13 patrols UC-16 was credited with sinking 42 ships, either by torpedo or by mines laid. UC-16 disappeared in October 1917. A postwar German study concluded that UC-16 probably sank after striking a mine off Zeebrugge.
SM UC-24 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 26 August 1915 and was launched on 4 March 1916. She was commissioned into the German Imperial Navy on 15 August 1916 as SM UC-24. In four patrols UC-24 was credited with sinking 4 ships, either by torpedo or by mines laid. UC-24 was torpedoed and sunk by French submarine Circé off Cattaro on 24 May 1917.
SM UC-25 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 29 August 1915 and was launched on 10 June 1916. She was commissioned into the German Imperial Navy on 28 June 1916 as SM UC-25. In 13 patrols UC-25 was credited with sinking 21 ships, either by torpedo or by mines laid. March–September 1918 she was commanded by Karl Dönitz, later Grand admiral. UC-25 was scuttled at Pola on 28 October 1918 on the surrender of Austria-Hungary.
SM UC-26 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 29 August 1915 and was launched on 22 June 1916. She was commissioned into the German Imperial Navy on 18 July 1916 as SM UC-26. In nine patrols UC-26 was credited with sinking 39 ships, either by torpedo or by mines laid. UC-26 was rammed and sunk by HMS Milne off Calais on 8 May 1917.
SM UC-40 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 20 November 1915 and was launched on 5 September 1916. She was commissioned into the German Imperial Navy on 1 October 1916 as SM UC-40. In 17 patrols UC-40 was credited with sinking 30 ships, either by torpedo or by mines laid. UC-40 was being taken to surrender but foundered in the North Sea en route on 21 January 1919.
SM UC-53 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 12 January 1916 and was launched on 27 February 1917. She was commissioned into the German Imperial Navy on 5 April 1917 as SM UC-53. In eight patrols UC-53 was credited with sinking 48 ships, either by torpedo or by mines laid. UC-53 was scuttled at Pola on 28 October 1918 on the surrender of Austria-Hungary.
SM UC-62 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 12 January 1916, laid down on 3 April 1916, and was launched on 9 December 1916. She was commissioned into the German Imperial Navy on 8 January 1917 as SM UC-62. In nine patrols UC-62 was credited with sinking 12 ships, either by torpedo or by mines laid. On 19 March 1917, the submerged Royal Navy submarine HMS E50 suffered damage in a collision UC-62 in the North Sea off the North Hinder Light Vessel. UC-62 struck a mine and sank in the North Sea off Zeebrugge, Belgium, on 14 October 1917.
SM UC-97 was a German Type UC III minelaying submarine or U-boat in the German Imperial Navy during World War I.
Type UC III minelaying submarines were used by the Imperial German Navy during World War I. They displaced 474 tonnes at the surface and 571 t submerged, carried guns, 7 torpedoes and up to 14 mines. The ships were double-hulled with improved range and sea-keeping compared to the UC II type. The type had better seagoing, maneuvering and turning capabilities than its predecessor, while underwater stability was reduced.
A coastal submarine or littoral submarine is a small, maneuverable submarine with shallow draft well suited to navigation of coastal channels and harbors. Although size is not precisely defined, coastal submarines are larger than midget submarines, but smaller than sea-going submarines designed for longer patrols on the open ocean. Space limitations aboard coastal submarines restrict fuel availability for distant travel, food availability for extended patrol duration, and number of weapons carried. Within those limitations, however, coastal submarines may be able to reach areas inaccessible to larger submarines, and be more difficult to detect.
