Question to the Ministry of Defence:

To ask the Secretary of State for Defence, on which dates in 2014 HMS Vengeance was berthed at the Devonport dockyard undergoing refurbishment; and what particular refit was being carried out during that time by Babcock Marine on behalf on his Department.

HMS Vengeance has been undergoing a Long Overhaul Period (Refuel) in Devonport Dockyard since March 2012. During this period she was docked from 16 April 2012 to 18 December 2014 and berthed from 18 December 2014 to 31 December 2014 following a successful "flood up".

During 2014, HMS Vengeance has had a major overhaul of equipment, including capability upgrades, to underwrite operational service for a further 10 year commission. This has included the refuelling of the nuclear reactor, which was completed in April 2014.
