You may well be right Malim,
if the Brazilians, Canadians, Australians or anyone else don`t come on board & order any ships, to help drive down costs, there may be only 9 or so built with possibly 4 smaller corvette sized patrol ships equipped with a helicopter & hanger ordered instead.
Possible names include the 14 previous Type 42 destroyer city names & those from the County class destroyers ie, Glamorgan, Fife, Hampshire, Devonshire, London (previously used as a Type 22 batch II), & Norfolk (previously Type 23).
Strong contenders, due to the fact that they haven`t been used since the 1950`s are the County class cruiser names : Suffolk, Berwick, Sussex & Shropshire.
Then there are previous frigate names of the 1950`s & 60`s, such as Lincoln, Exmouth, Torquay, Blackpool, Salisbury, Rothesay, & Chichester.
Lots of competition for names, a political hot potato.
