Invincible Class (1980) CVS
class was conceived in the late 1960, following the cancellation of the
CVA-01 class of fleet carriers in 1966.
The prime requirement was to carry and operate viable numbers Sea King Helicopters. For political reasons any thought of Aircraft Carriers was forbidden, and the designs were known as Through-deck Command Cruisers. No ability to operate fixed wing aircraft were allowed in the design.
However development of the Sea Harrier was later authorised. This allowed the Royal Navy to re-establish some organic air defence to the Fleet, and the Class allowed to be redesignated as Support Aircraft Carriers. Development of the Ski-jump allowed the Sea Harriers payload to be very usefully increased.
The value of this was demonstrated in 1982 during operations to recover the Falkland Islands following their invasion by Argentina.
At that time Invincible was the only ship of the Class in commission, and her support of the larger Hermes allowed the operation to proceed. The risk of only being able to operate one hull would have put the entire operation in great jeopardy.
Illustrious was rushed to completion and commissioned just too late to see service in the Falklands. However she was rushed to the South Atlantic to relieve Invincible who returned home after spending a record 166 days continuously at sea, a record.
The third ship of the Class Ark Royal commissioned in 1985, following which there are normally two of the class in commission with the third in reserve or undergoing refit.
The original air group was established at 8 Sea Harriers, 9 ASW Sea Kings and 2 AEW Sea Kings. However in 1999 Illustrious was modified by removing the Sea Dart missile launcher and associated magazines from the bow, to provide increased flight deck area forward as well as additional storage for aircraft ordinance. This allows an additional 6 RAF Harriers or 9 Sea Harriers to be carried. Ark Royal was similarly refitted in 2001, and Invincible will follow.
There are plans being made to build two 40,000 ton aircraft carriers to enter service in 2013. These will replace the three Invincible Class ships. However as usual financial considerations mean these plans must be considered fluid until the ships actually appear.

Official Role 2004
The Royal Navy website states in May 2004 that the role of the CVS is
Aircraft have mobility, flexibility and versatility
which are the keywords of a modern defence strategy. The CVS and its
Carrier Air Group (CAG) can move to almost anywhere in the world in
international waters. Aircraft may be the first on the scene in a
particular operation giving both politicians and military commanders
options, including early reconnaissance, the landing of special forces and
land attack from the air. Additionally the CVS provides air traffic
control, fuel, maintenance and briefing facilities. Events throughout the
1980s and 90s have demonstrated the high value of the CVS.
