The phrase was "How many Ark Royals have there been in The Royal Navy".
There have been 5 ships of the name Ark Royal
My question however is. is "Ark Royals" the correct plural form?
Should it instead be "How many Arks Royal have there been in The Royal Navy?" or is that all moot and I should be asking "How many HMSs Ark Royal have there been in The Royal Navy?"
