SM UC-99 was a German Type UC III minelaying submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 12 January 1916 and was launched on 17 March 1918. She was commissioned into the German Imperial Navy on 20 September 1918 as SM UC-99.[Note 1] As with the rest of the completed UC III boats, UC-99 conducted no war patrols and sank no ships. She was surrendered to Japan on 22 November 1918. The U-boat was renamed O-5 for Japanese service from 1920 to 1921. O-5 was dismantled at the Yokosuka Navy Yard between March and June 1921. The hulk of O-5 was disoposed of as a gunnery and torpedo target in October that same year.[1]
