Question to the Ministry of Defence:
To ask the Secretary of State for Defence, if she will publish the seven Astute class submarines by (a) name, (b) actual or estimated in-service date and (c) estimated out-of-service date.
HMS ASTUTE, HMS AMBUSH, and HMS ARTFUL have entered service with the Royal Navy. AUDACIOUS, ANSON, AGAMEMNON and AGINCOURT are in various stages of build.
The planned in-service and out-of-service dates for Royal Navy submarines are withheld as disclosure would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces.
