Privatisation
Babcock Thorn, a consortium operated by Babcock International and Thorn EMI, was awarded the management contract for Rosyth dockyard in 1987; with Rosyth Dockyard becoming a government owned, contractor run facility. This contract was awarded in parallel with Devonport Management Limited's contract to run Devonport Dockyard, Plymouth. 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 1984 Rosyth was chosen as the sole location for refitting the Royal Navy's nuclear submarine fleet, and in 1986 extensive rebuilding commenced to facilitate this new role. However, in 1993, the government switched the refitting role to Devonport Dockyard.
Nuclear submarine decommissioning
Seven nuclear submarines were stored at Rosyth in 2007. In 2018, the Public Accounts Committee criticised the slow rate of decommissioning of these submarines, with the Ministry of Defence admitting that it had put off decommissioning due to the cost.
The Royal Navy's two carriers were constructed across six UK shipyards, with final assembly at Rosyth.
Administration of the dockyard
The admiral-superintendent was the Royal Navy officer in command of a larger Naval Dockyard. The appointment of admiral-superintendents dates from 1832 when the Admiralty took charge of the Royal Dockyards. Prior to this larger dockyards were overseen by a commissioner who represented the Navy Board.
