It is worth explaining why I, and my fellow military chiefs, proposed this move. Carriers are expensive - there is no way around that. But they offer a capability that few can match: an independent, flexible, sovereign base, not tied to other countries' wishes, that can operate around the world.
By choosing the short take-off and vertical landing (STOVL) model of the Joint Strike Fighter over the Carrier Variant that we had previously ordered for our two new aircraft carriers, the UK is significantly shortening the time it will take to deploy our maritime air power.
For me, this is the key factor. We are getting an exceptional military tool that is capable of projecting power, deterring our enemies and supporting our friends. In an uncertain world, this is a capability that I know we all wish to have sooner rather than later.

Whilst apparently it is strange to have
a General pontificating on a subject that involves ships and fast jets
maritime air power and independent power projection are the priorities behind this decision.
