SM U-158 [Note 1] was a Type U-158 submarine of the Imperial German Navy, built during the First World War.

Contents

SM U-158 was one of six 810-ton boats ordered in February 1917. [2] She was one of two ships built to an improved design developed from the Type U-115 design, along with her sister, SM U-159. [3] They were known as 'Project 25', and had a greatly increased radius of action. Both ships were built at Kaiserliche Werft Danzig, with U-158 being launched on 16 April 1918. [3] The war ended before she could see active service, and she was broken up in 1919. [3]

SM <i>UC-5</i> German Type UC I minelayer submarine

SM UC-5 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy during World War I. The U-boat had been ordered by November 1914 and was launched on 13 June 1915. She was commissioned into the German Imperial Navy on 19 June 1915 as SM UC-5. She served in World War I under the command of Herbert Pustkuchen and Ulrich Mohrbutter.

SM U-115 was a German Type U 115 U-boat of the Imperial German Navy built at Schichau-Werke, Elbing. As her sister ship SM U-116, she was never completed and ultimately broken up in Danzig after the armistice. Her main engines were used in M/S Adolf Sommerfeld ex SMS Gefion. Both boats had been offered to the IGN free of charge by Schichau in an attempt to gain experience in building submarines. When construction of the two boats began to lag behind due to shortages in raw materials and lack of experience in submarine construction, they were declared "war boats" (Kriegsboote), formally ordered by the Reichsmarineamt and given their respective designation. Though 14 more boats of the class were ordered on 29 June 1918 for delivery in 1919, on 20 October 1918, Schichau-Werke reported U 115 would not be ready for delivery until the spring of 1919. None of the 16 planned units would be complete before the end of the war.

SM UB-9 was a German Type UB I submarine or U-boat in the German Imperial Navy during World War I. UB-9 was ordered in October 1914 and was laid down at the AG Weser shipyard in Bremen in November. UB-9 was a little under 28 metres (92 ft) in length and displaced between 127 and 141 tonnes, depending on whether surfaced or submerged. She carried two torpedoes for her two bow torpedo tubes and was also armed with a deck-mounted machine gun. She was launched and commissioned as SM UB-9 in February 1915.

SM UB-11 was a German Type UB I submarine or U-boat in the German Imperial Navy during World War I. UB-11 was ordered in October 1914 and was laid down at the AG Weser shipyard in Bremen in November. UB-11 was a little under 28 metres (92 ft) in length and displaced between 127 and 141 tonnes, depending on whether surfaced or submerged. She carried two torpedoes for her two bow torpedo tubes and was also armed with a deck-mounted machine gun. She was launched and commissioned as SM UB-11 in March 1915.
