What would I call it? I would call it Integrated ASW. It seems fair enough for the towed array equipped frigate to take charge, cuing the MPA and dipping sonar equipped helicopters as necessary.
I feel a bit daft for banging on about the role carriers and their aircraft can play in protecting shipping or amphibious forces, without mentioning that as well as acting as an escorting force, they can be used as a barrier to stop hostile forces getting near our vulnerable assets. Given the inability of the MOD/RN media people to state that the carrier does do things like air defence and ASW, we might be waiting a long time for a press release describing the contribution made to Exercises
Cold Response 22 and
Northern Viking 22. After all it was the BBC and Sky that reported the thirty intercepts of Russian jets by F-35B Lightnings from HMS
Queen Elizabeth during the CSG21 deployment. or the way frigates and Merlins (and our own SSN) kept track of Russian and Chinese submarines, instead of RN/MOD news stories.
