To ask the Secretary of State for Defence what recent assessment he has made of the reliability of (a) power generation and (b) the main bus bars of the fleet of Type 45 vessels.
As with all equipment in all classes of ship, the electrical systems in the Type 45 destroyers undergo a continual process of performance assessment and routine maintenance, to ensure they are maintained at the highest standard of availability and reliability.
Concerns about the reliability of the Type 45 Class power and propulsion system did emerge during first of class sea trials for HMS Daring. As a result, an independent power and propulsion system performance review was commissioned. This review, which reported in March 2011, highlighted a number of unconnected causes of system and equipment failure and these issues have been addressed through a series of design changes, resulting in a marked improvement in performance. Work to complete the implementation of the recommended design changes is continuing.
There have been no problems with the reliability of bus bars on the in-service Type 45 destroyers.
