Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what the seaworthiness is of HMS (a) Astute and (b) Ambush.
The safety of the UK submarine fleet is of paramount importance. The Ministry of Defence assesses seaworthiness for submarines through a robust sea clearance process. This assessment is kept under continuous review.
I am withholding the seaworthiness state of each submarine as its disclosure would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces.
