The collection was brought to Birkenhead in 2002 and was moored in the West Float of the Birkenhead docks complex. The fleet consisted of the frigate HMS Plymouth and the submarine HMS Onyx, both from the Falklands War; the minehunter HMS Bronington; the German U-Boat U-534 and LCT 7074, the last surviving tank landing craft that took part in D-Day. In May 2006 HMS Onyx was sold to the Barrow-in-Furness businessman Joe Mullen, for a reported £100,000 as a 'gift to the people of Barrow'. It left Birkenhead on 13 June 2006 to form the centrepiece of a new heritage museum in Cumbria.
