Here's Ark Royal in Portsmouth last Sunday with the Spinnaker Tower in the background (well worth a visit!):
Interesting also to note that we can't afford to build ships of our own, but we can for other countries. Here's a picture of the brand new Port of Spain, a Coastguard Protection vessel for the Trinidad & Tobago government built in the BAe Systems shipyard in Portsmouth and still undergoing sea trials. There is a sister ship to this being built in the shipyard as well, also destined for Trinidad & Tobago.
