On 17 January 1911, U-3 sank near Kiel harbour in Heikendorfer Bay because of an unclosed ventilation shaft valve. Its entire 30-man crew was rescued by SMS Vulkan via torpedo tube. Amongst the saved crew was Otto Weddigen, the later commander of U-9 and Paul Clarrendorf, the commander of U-boot-Abnahme-Kommando in Kiel which enlisted U-boat crews.

U-3 began her World War I career as a training boat from 1 August 1914 to 11 November 1918. On 1 December 1918, the surrendered boat was being towed to Preston to be broken up when she sank. Unlike the first two U-boat designs, the third design was fitted with a 5 cm (2.0 in) SK L/40 deck gun.
