HMS Cougar was old even by Royal Navy Standards. Twenty-four years since her launch, and twenty years since she left the Falklands. Now she was going back, the last of the Gun Diesels. A left over from the countless defence cuts as a training ship, and quietly forgotten by all. Fifties technology, in a shallow draft, and a slow speed, but in this 'can do Navy' she could be useful in the first line of defence against the Exocet missile, simply because she was expendable.
