Type U 127 submarine was a class of U-boats built during World War I by the Kaiserliche Marine.

The U-boats carried 16 torpedoes and had various arrangements of deck guns.

[citation needed] They carried a crew of 44 and had excellent seagoing abilities with a cruising range of around 10,000 nautical miles (19,000 km; 12,000 mi).

[citation needed] There were eight Type U 127 submarines built for the Kaiserliche Marine between 1913 and 1918.

Only one was launched before the Armistice with Germany in 1918 and was subsequently surrendered to the Allies.
