From the SDSR document:
The current, limited carrier-strike capability will be retired. We must face up to the difficult choices put off by the last Government. Over the next five years combat air support to operations in Afghanistan must be the over-riding priority: the Harrier fleet would not be able to provide this and sustain a carrier-strike role at the same time. Even after 2015, short-range Harriers – whether operating from HMS Illustrious or HMS Queen Elizabeth – would provide only a very limited coercive capability. We judge it unlikely that this would be sufficiently useful in the latter half of the decade to be a cost-effective use of defence resources.
