Steven Paterson – 2015 Parliamentary Question to the Ministry of Defence

The below Parliamentary question was asked by Steven Paterson on 2015-11-06.

To ask the Secretary of State for Defence, how many faults have been found aboard HMS (a) Astute, (b) Ambush and (c) Artful since it left dry dock.

Mr Philip Dunne

The process for reporting and assessing deficiencies against the material state of a submarine does not use the definition of a fault. The material state of a submarine is formally assessed at the end of each maintenance period. In the time in between maintenance periods, Ship’s Staff report changes to this assessed material state using the Operational Defect reporting process.
