HMS Meteorite was an experimental U-boat developed in Germany, scuttled at the end of World War II, subsequently raised and commissioned into the Royal Navy. The submarine was originally commissioned into the Kriegsmarine on 13 March 1945 as U-1407. She was built around a Walter engine fueled by high-test peroxide (HTP), the fuel known as T-Stoff in German service.

History

The three completed German Type XVIIB submarines were scuttled by their crews at the end of the Second World War, U-1405 at Flensburg and U-1406 and U-1407 at Cuxhaven, all in the British Zone of Occupation. [4] U-1406 and U-1407 were scuttled on 7 May 1945 by Oberleutnant zur See Gerhard Grumpelt even though a superior officer, Kapitän zur See Kurt Thoma, had prohibited such actions. Grumpelt was subsequently sentenced to seven years' imprisonment by a British military court. [5] [6]

At the Potsdam Conference in July 1945 U-1406 was allocated to the United States and U-1407 to the United Kingdom, and both were soon salvaged. [4]

Royal Navy service

U-1407 was salvaged in June 1945, and transported to Barrow-in-Furness, where she was refitted by Vickers with a new and complete set of machinery also captured in Germany, under the supervision of Professor Hellmuth Walter. Because she was intended to be used solely for trials and possibly as a high-speed anti-submarine target, her torpedo tubes were removed. [4] She was commissioned into the Royal Navy on 25 September 1945 and renamed HMS Meteorite.

During 1946 Meteorite carried out a series of trials under the guidance of Walter and his original team from Germaniawerft, Kiel. The trials raised considerable interest in the possibility of HTP as an alternative to nuclear power as air-independent propulsion and the Admiralty placed an order for two larger experimental Walter boats based on the German Type XXVI, the Explorer-class submarines HMS Explorer and HMS Excalibur, to be followed by an operational class of 12 boats.

Meteorite was not popular with her crews, who regarded the boat as a dangerous and volatile piece of machinery. She was officially described as "75% safe". [7] She was difficult to control due to aircraft-type controls and a lack of forward hydroplanes.

Fate

Meteorite's Royal Navy service came to an end in September 1949, and she was broken up by Thos. W. Ward of Barrow-in-Furness.

The German Type IXA submarine was a sub-class of the German Type IX submarine built for Nazi Germany's Kriegsmarine between 1937 and 1938.

The inspiration for the Type IXA submarine came from the German Type IA submarine, which had a similar diving depth and identical submerged horsepower.
