Type 82 as a task-force command ship

Did Type 82 still have a useful role after Ark Royal, and would more ships have helped?

Yes; HMS Bristol served as a command platform, and another Type 82 would have been valuable for task-force command in 1982.

Type 82 retained a role as a task-force command ship after Ark Royal. It took over work previously done by the Tiger-class cruisers. In 1982, Bristol led a later group of ships south to the Falklands. Another Type 82 would have been useful for Clapp's command, where an old County-class destroyer was an available alternative.
