With the toy boats!
The "global corvette" nonsense has been going on for a awhile. Anything smaller than the old Leanders will be good for nothing outside the North Sea. Yes people like the Israeli Navy did a 30 day deployment once to prove it could be done. Stayed in the Med. Send a proper warship or stay at home. Of course if you think Britain can ignore anything east of suez than that wont be a problem.
