Would Turkey permit Britain to send a Queen Elizabeth-class carrier into the Black Sea?
Short answerA carrier would be too provocative; NATO could instead move land-based fighters closer through Black Sea allies.
NotesA Queen Elizabeth-class carrier entering the Black Sea would be needlessly provocative in the scenario being discussed. Moving fighters onto bases in allied countries could provide air power close enough to cover the area with a less conspicuous political signal. The contrast concerns the political effect of a capital ship rather than the availability of regional air power. The answer does not address the separate legal rules governing straits passage.
