Rosyth & Devonport (Submarines)

Rosyth Dockyard was used for the refit, repair and maintenance of operational nuclear submarines from the 1960s until 2003. As each submarine reached the end of its operational life, it was defueled and decommissioned onsite. Phase 1 of the decommissioning is the removal of low-level waste from the decommissioned submarines.

Its primary role now is the dismantling of decommissioned nuclear submarines. It is also the integration site for the Royal Navy's newest aircraft carriers.
