HMS Caledonia'''
was first opened in 1937 and responsible for artificer apprentice training from 1937 to 1985, with many thousands of young men going through training. Following the consolidation of naval training in 1985, the site lost its training status with the former apprentice training moving to in Gosport. The site was subsequently reduced to become part of HMS Cochrane''. Just before the beginning of the
Second World War, Boys' Training Ship Caledonia was based here. By this time Admiral Sir
Charles Ramsey, the
Commander-in-Chief, Rosyth, responsible for naval operations in the area, was based at just down the road at the Dockyard. In 1993 the
Ministry of Defence announced plans to privatise Rosyth. Babcock International, who had bought out Thorn's share of the original Babcock Thorn consortium, was the only company to submit a bid and after protracted negotiations purchased the yard in January 1997. In 1996, following the decommissioning and privatisation of the
Royal Naval Dockyard Rosyth,
MoD Caledonia was opened on the site of the former dockyard. Following the
Options for Change review and the
collapse of the Soviet Union, the reserve unit was moved from
Pitreavie Castle to HMS
Caledonia, where it has been based ever since. this was later extended to 2026. On 1 April 2023 it was renamed HMS Caledonia and its future is assured. == Based units ==
