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

Design

The U-boats carried 16 torpedoes and had various arrangements of deck guns. Some had only one; others had two 15 cm (5.9 in) SK L/45 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]}

List of Type U 127 submarines

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. The unfinished boats were broken up for scrap after the war.^{[citation needed]}
