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.
