Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how many decommissioned nuclear submarines were dismantled in each of the last five calendar years.

Good progress continues to be made with dismantling decommissioned submarines in Rosyth. The first stage of dismantling, including the removal of all Low-Level radioactive Waste, has been completed on four platforms, Swiftsure, Resolution, Revenge and Repulse. Swiftsure will be the first submarine to be fully dismantled by the end of 2026.
