Question to the Ministry of Defence:

To ask the Secretary of State for Defence, when the repair to the submarine lift at HMNB Clyde is due for completion; and what the estimated cost was of that repair.

The shiplift at HMNB Clyde is undergoing scheduled routine maintenance and upgrade work.

Costs for key assets in the naval base are included in the routine maintenance contract with Babcock. It would not be appropriate to provide detailed availability of critical infrastructure assets due to operational sensitivities.
