SM U 135 was a German submarine of the Imperial Navy .

history

U 135 was a boat which was referred to as a large submarine or as a U-cruiser forerunner . The design itself came about under the name Project 42 . It was on November 4, 1916 in the Imperial Shipyard Gdansk laid down on and put on 20 June 1918 John spit into service.

After long test drives and remaining work, U 135 was still at home at the end of the war. On October 9, 1918 it was the III. U-Flotilla in Wilhelmshaven has been assigned. On October 22nd, the boat was moved to the Heligoland base. From here, U 135 was to take part in a planned action by the deep-sea fleet . But on October 24th the boat was back in Wilhelmshaven and on October 31st on the Schillig Reede. On November 6th it returned to Wilhelmshaven and was commissioned to help suppress the uprising in the Navy. Together with the IV. Torpedo Boat Half Flotilla, U 135 ended the mutiny on board the ships of the line SMS Thüringen and SMS Helgoland by threatening to sink both ships. After the war it was given to Great Britain as spoils of war.

U 135 did not undertake any enemy voyages and therefore could not record any successes against enemy ships.

The design of U 135 was later recognized as exemplary by submarine builders and served as a model for the construction of the US submarines USS Cachalot and USS Cuttlefish .

Whereabouts

Before the boat was picked up for scrapping by the Royal Navy , students at Loughborough University , Leicestershire , England , under the direction of JF Driver, removed the drive motors and various other components. These parts were then reassembled in a log cabin on Packe Street in Loughborough and used in a generator station in 1937 until it was closed in 1949.

In 1921, when it was being dismantled, the boat ran aground and was lost.

Remarks

  1. The SM stands for His Majesty and refers to the then ruling German Kaiser Wilhelm II. It reads completely: His Majesty's U-boat , for surface units His Majesty's ship - SMS for short
