Queen Elizabeth Class Aircraft Carriers
Queen Elizabeth Class Aircraft Carriers The Capability The platform element of the Carrier Strike capability will be provided by the Queen Elizabeth Class aircraft carriers. A staged approval to Main-Gate in 2007 led to the formation of the Aircraft Carrier Alliance (comprising MOD and Industry) and contract award in 2008 to deliver the programme with In-Services Dates originally planned for 2014 and 2016. The continuing need for the Carrier Strike capability was confirmed in the 2010 Strategic Defence and Security Review. |

The Aircraft Carrier Alliance acknowledged that there was a requirement to reduce costs at the time of the contract award on the basis that concerted management action in the early years of the project would allow this to reduce. In the event, the disruption caused by initial re-costing activity and then the Equipment Examination prevented successful delivery of the originally planned cost reduction - as this would not be achieved, MOD considered it prudent to formally recognised this in its revised estimate. During 2010 Diesel Generators were installed in Lower Block 2 (Portsmouth) and in March 2011 in Lower Block 04 (Govan) on HMS Queen Elizabeth. In early 2011, the Goliath Crane, which will be used to assemble the carriers, arrived at Rosyth and is now undergoing preparations for erection and commissioning in the summer. | The Investment Approvals Board approved the Queen Elizabeth Class Final Target Cost for the pre-Strategic Defence and Security Review programme on 31 January 2011 to £5,242 million, which has provided a stable cost and schedule baseline for the programme going forward. Long-lead equipments for HMS Prince of Wales have been ordered over the last four years, with many of the major components already in-build or delivered (e.g. Diesel Generators). The Strategic Defence and Security Review concluded that the Carrier Strike capability would be based around the Carrier Variant of the Joint Strike Fighter, which would fly from an operational Queen Elizabeth Class carrier converted to a Carrier Variant configuration. It also confirmed that both carriers would be built, with one to be operational and the second kept in extended readiness or sold. | |||||
