The U-Boats that Surrendered. U-1407 (HMS Meteorite) in the Royal Navy - 1945 to 1949 by Derek Waller - 31 Oct 2011
The Potsdam Agreement signed on 2 August 1945 included the decision to allocate just 10 U-Boats to each of the three Allies for technical assessment and experimental purposes. This led to the creation of the Tripartite Naval Commission (TNC) which was charged with determining the list of U-Boats to be allocated to each country. Thus, they recommended which U-Boats should be retained by the UK, one of which was the Type XVIIB U-Boat, U-1407, which was powered by a Walter gas turbine using high-test peroxide (HTP) as its fuel.

The U-Boats that Surrendered - The U-Boats Allocated to the UK in 1945 (Version 2) by Derek Waller - 9 Oct 2011
The 1945 post-war Potsdam Agreement signed on 2 August 1945, which included the requirement to allocate 10 U-Boats to each of the three Allies (USA, UK and USSR), led to the creation of the Tripartite Naval Commission (TNC), which was charged with determining exactly which U-Boats would be allocated to each country. Thus, representatives of the TNC visited the UK in August and September 1945 to inspect all the surrendered U-Boats held in the UK, mainly at Lisahally and in Loch Ryan. As a result, they decided which U-Boats should be recommended to the Commission for formal allocation and therefore transfer to each of the three Allies.
