SM U-11[a] was one of 329 submarines which served in the Imperial German Navy during World War I. The boat was sunk in December 1914 after hitting a naval mine off the coast of Belgium.

Service history

U-11 was built at Kaiserliche Werft Danzig between 1908 and 1910. It was launched in April 1910 and commissioned into the Navy later in the year. At the start of World War I it was commanded by Kapitänleutnant Ferdinand von Suchodoletz.

During the war U-11 took part in two war patrols. The boat was sunk on 9 December 1914 off the Belgium coast after striking a mine. It did not sink any merchant shipping during its career.
