The below Parliamentary question was asked by Douglas Chapman on 2016-02-01.

To ask the Secretary of State for Defence, on which Royal Navy ships were repairs carried out from March 2011 following the review of electrical and propulsion systems; and what the cost of those repairs was.

Mr Philip Dunne

The Independent Power and Propulsion System Performance Review, dated March 2011, highlighted sixteen recommendations to improve the reliability of the Type 45 Destroyer’s Power and Propulsion system. Fourteen of the recommendations have been completed across the class.

The remaining two recommendations, involving modifications to existing training procedures and documentation, have been incorporated into day to day business.

Implementation of these recommendations has directly contributed to an improvement in reliability.

All but one of the fourteen tasks were implemented under the Type 45 Destroyer Contract For Availability (CFA) arrangement with BAE Systems, at no additional cost to the Ministry of Defence.

The only task not covered under the CFA contract cost a total of £24,000 for the six Type 45 ships.

The below Parliamentary question was asked by Douglas Chapman on 2016-02-01.

To ask the Secretary of State for Defence, how many times Daring Class Type 45 Destroyers underwent total electrical failure in the (a) Persian Gulf, (b) Strait of Hormuz, (c) Mediterranean Sea, (d) Indian Ocean and (e) North Atlantic Ocean.

Mr Philip Dunne

In the interests of National Security I am not prepared to release information concerning the type or nature of any failure or defect concerning our operational Units as to do so would allow deductions to be made as to their operational capability and effectiveness.

The below Parliamentary question was asked by Douglas Chapman on 2016-02-01.

To ask the Secretary of State for Defence, which common electrical and propulsion systems are shared between the T26 Global Combat Ship and the Type 45 Destroyer.

Mr Philip Dunne

Due to the specific requirements of Anti-Submarine Warfare operations and the availability of equipment on the open market, the Type 45 and Type 26 Global Combat Ship (T26 GCS) electrical and propulsion system architectures are fundamentally different; no major equipment will be common to both.

Lessons learned from the Type 45 programme and the in-service experience drawn from the Type 23 Anti-Submarine Warfare Frigates have all been applied to the T26 GCS electrical and propulsion system design.

The below Parliamentary question was asked by Douglas Chapman on 2016-02-01.

To ask the Secretary of State for Defence, whether his Department will pay out of the public purse for the cost of repairs to the electrical and propulsion systems on the Daring Class Type 45 Destroyers.

Mr Philip Dunne

A number of early modifications were implemented under the Type 45 Destroyer Contract for Availability arrangement with BAE Systems, at no additional cost to the Ministry of Defence (MOD). The initial work to prove the concept of upgrading the diesel generators was co-funded by BAE Systems and the MOD. Subject to main gate approval, the upgrade will be funded by the MOD.

The below Parliamentary question was asked by Douglas Chapman on 2016-02-01.

To ask the Secretary of State for Defence, where his Department plans for work to take place on rectifying the electrical and propulsion faults on the Daring Class Type 45 Destroyers.

Mr Philip Dunne

A number of measures to improve the reliability of the Type 45 Power and Propulsion systems have been identified and the ongoing programme to implement these changes continues to deliver positive results, with the majority of work undertaken so far being at Her Majesty’s Naval Base, Portsmouth.

In addition, and as part of the Strategic Defence and Security Review 2015, we are committed to improving system resilience by adding upgraded diesel generators to provide further electrical generation capacity. Alternative technical options and a variety of delivery models are currently being explored with several competing industrial partners. The total cost and timetable for implementing the diesel generator upgrade will be determined at the main investment decision. I am withholding details of our current time and cost estimates as premature disclosure of this information could prejudice the commercial interests of the Department.

To ask the Secretary of State for Defence, what work will be required on each of the Daring Class Type 45 Destroyers in the fleet due to electrical and propulsion faults; and what estimate he has made of the cost of such work.
