Question to the Ministry of Defence:
To ask the Secretary of State for Defence, how many reports have been made on the assessed material state of HMS (a) Astute, (b) Ambush and (c) Artful.
A range of reports are generated on the material state of all Royal Navy submarines. Given the broad range of reporting that is undertaken and the large range of highly complex engineering systems reported on, this information is not held centrally and could only be provided at disproportionate cost.
