SM UC-48 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 20 November 1915, laid down on 1 February 1916, and was launched on 27 September 1916. She was commissioned into the German Imperial Navy on 6 November 1916 as SM UC-48.[Note 3] In 13 patrols UC-48 was credited with sinking 35 ships, either by torpedo or by mines laid. UC-48 was severely damaged by a depth charge attack by HMS Loyal on 20 March 1918 that ruptured the fuel tanks. Unable to return to Zeebrugge, the boat was steered to El Ferrol, Spain, where she and her crew were interned for the rest of the war. The Spanish authorities removed UC-48's propellers to prevent any attempts at leaving port.[1]
Notes
- ↑ Tarrant does not list a beam measurement for UC-46 to UC-48. All other completed UC II submarines had a beam of 17 ft 4 in (5.28 m).
- ↑ Tarrant does not report a submerged speed for UC-46 to UC-48, but the range of underwater speeds of other completed UC II boats was as given.
- ↑ "SM" stands for "Seiner Majestät" (English: His Majesty's) and combined with the U for Unterseeboot would be translated as His Majesty's Submarine.
