Would the Royal Navy accept a Type 22 frigate with neither Exocet nor a 4.5-inch gun?
Short answerProbably not. Batch 1 Type 22s omitted the gun because they carried Exocet; removing both would go too far.
NotesBatch 1 Type 22 frigates carried Exocet without a 4.5-inch gun. Their armament demonstrates that the Royal Navy accepted missiles in place of a medium gun. Removing Exocet as well would probably make the proposed armament unacceptable. The later Type 22 design changed the arrangement again.
