Introduction: The CVF Project

The "Future Aircraft Carrier" (CVF) project  forms the core element - although far from the most expensive - of the MOD's Carrier Strike Programme.  The other main elements being the Joint Combat Aircraft, the Maritime Airborne Surveillance and Control platform and Military Afloat Reach Sustainability (MARS) support ships. 

The requirement for CVF stems directly from the 1998 Strategic Defence Review by the then new Labour government. This policy was re-endorsed in the New Chapter work published in 2002 and then again by the Defence White Paper in December 2003.  A CVF, with its embarked air group, will provide the aviation means for excursionary warfare in support of the land campaign from the sea, avoiding the need for concrete runways and permission for overflights - i.e. the UK can intervene at a posed threat at a time of its choice.  This national capability for ships with embarked aircraft and support equipment is known collectively as ‘carrier strike’.

The Future Aircraft Carrier project - also occasionally referred to as the "Carrier Vessel for the Future" project - is expected to deliver to the Royal Navy two new aircraft carriers -  HMS Queen Elizabeth and HMS Prince of Wales as replacements for the three small (20,000 tonnes) carriers of the Invincible class.   At about 65,000 tonnes full load and 920ft long, the new carriers will in terms of both dimensions and tonnage be the largest warships ever to enter service with the Royal Navy. 

 

Nomenclature Note:

Under the standard NATO warship classification system (largely derived from the USN), CV is the basic abbreviation for aircraft carrier. 

The "CVF" Project began as CVSG(R) - a Replacement aircraft carrier (CV),  Support, Guided missile  - i.e. a replacement for the Invincible-class.

In 1997-8 CVSG(R) was changed to the handier term of Future Aircraft Carrier, or CV(F).  By 1999 the brackets were often being dropped, leaving CVF.

In late 2005 the expression "Carrier, Vehicular, Future" began to be used by the MOD - apparently because of a perceived need to have CVF be a direct one-to-one abbreviation of words.

In 2006 the term "Carrier Vessel for the Future" also appeared.  This seems to link to American phrasing, for example in regards to the carrier variant (CV) of the F-35 Joint Strike Fighter.

In January 2003 BAE Systems was selected as the preferred prime contractor for the CVF project, but using a Thales UK developed design concept, and the two companies formed the joint Future Carrier Alliance to build the ships.  Subsequently the project suffered badly from disputes regarding responsibilities, cost and timescales, and even the basic design features such as the ships displacement and dimensions have been subject to frequent significant changes. 

The first part of what had become a two stage Main Gate approval process was announced in December 2005 - with £300 million to be spent to completing the detailed design for CVF. 

A £3.8 "main investment" decision to actually order and build the ships (stage two of the Main Gate) was announced on 25 July 2007.  The target dates for the ships to enter service are 2014 and 2016.

Separately, France plans to build a tailored variant of CVF as the second aircraft carrier (porte-avions No.2, PA2) for the Marine Nationale (French Navy), a companion to its existing existing nuclear powered aircraft carrier FNS Charles de Gaulle.    On 24th January 2006, the UK and France agreed to co-operate to create a Common Baseline Design, based on the CVF Delta design to meet France’s requirements for an additional carrier.  Significant savings are expected to result from the UK and France sharing the detailed design costs, and some joint procurements of equipment.

 

Project Origins

In the mid-1990's it was expected that the Royal Navy's (RN's) three Invincible-class of small aircraft carriers would decommission between about 2010 and 2015 - after 30 years years of service.

Preliminary studies in to a possible replacement started as early as 1994. Early thinking generally assumed three new small (20,000 tonnes) carriers, although a wide variety of alternatives were considered, ranging from new build ships of various sizes and sophistication, through to rebuilding of the existing Invincible-class, to merchant ship conversions, and even the purchase of old US Navy carriers.

in 1995 BAe-SEMA studied a 30-year ship life-extension programme for the Invincible-class.  They found that a SLEP was technically risky on account of existing hull fatigue and the problems of inserting an additional hull section to meet the need to increase aircraft capacity.  It was found that the the hull could be cut safely at one point only, directly in front of the bridge, and inserting a new 80ft hull section would increase aircraft capacity by just four.  Even when stretched, the CVS's comparatively narrow beam and constricted hangar layout would continue to pose operational problems and, moreover, and could not provide the dramatic increase in air wing capacity offered by the larger new-build aircraft carriers.  It was concluded that a "SLEP and Stretch" was disproportionately expensive given the limited capability improvement conferred by the modifications.

The eventual decision to replace the three Invincible-class aircraft carriers with two much larger Future Aircraft Carrier (CVF) vessels by 2015 was perhaps the single most important outcome of the UK government's 1998 Strategic Defence Review (SDR).  The SDR had found that the ability to deploy offensive airpower would be central to future force projection operations.  However, it also noted that the UK couldn't be certain that there will always be access to suitable airbases.  Successive operations in the Gulf, Bosnia and Kosovo had demonstrated that aircraft carriers could provide valuable flexibility, as well as offering a coercive presence which contributes to conflict prevention and forestalls the need for war.  The current Invincible-class aircraft carriers were designed for Cold War antisubmarine warfare operations in the North Atlantic.  However, the limited size of their air groups meant that they were now less able to fulfil the increasingly challenging security demands facing the UK around the world.   There was thus a clear need for larger vessels, each of which would be capable of carrying and operating a larger and more powerful carrier air group, if the costs could be contained within affordable limits.   The formal requirement - ST(S) 7068 - was subsequently approved (called "Initial Gate") at the end of 1998. 

However, despite the SDR decision to build new carriers, the MoD tried to pre-empt any opposition to the CVF project (not least from the Treasury) by revisiting the lowest cost  alternative - a refit option of the existing Invincible's with no hull plug "stretch".  In early 1999 an invitation to tender for a Further Special Refit (FSR) study contract was issued to consider the feasibility of extending the service life of two of the three existing Invincible class CVS's by 10 years, i.e. the required in-service date for their replacements would change from 2012 to 2022.  The FSR feasibility study addressed various issues including the costs of a life-extension refit; the operational costs of the converted vessels; adaptation costs to enable the ships to operate JSF-class aircraft; and an appropriate refit programme.   The work was completed before CVF Initial Gate in November.  Although its conclusions were never published, the FSR study apparently found that the CVS's could not be cost-effectively altered to safely operate the STOVL variant of the Joint Strike Fighter which was now firmly pencilled in as the RN's Future Carrier Borne Aircraft, partly because they were simply too small for any plane much larger than the Harrier.  The FSR approach would therefore only produce short-terms savings while resulting in a considerable loss of capability compared with CVF, the approach was thus played down by officials and industry.
