Not far off Kev. Airborne radar is a useful means of keeping a submarines head down, but there are a lot of caveats:
-You need literally constant saturation of the entire area if you expect to reliably catch a periscope on the surface, and even so you may not be able to get a solid fix in the time you have available (remember the etymology of the Perisher course: how to have your periscope up for the absolute minimum time possible).
-One airborne Hawkeye would not be enough to provide radar saturation of the ocean surface around a carrier/CVBG, especially if it is still flying a meaningful AEW pattern.
-If the swell is anything over a dead calm, then a ballsy/good sub commander should be able to maneuver even with pretty heavy airborne radar coverage.
-Sticking a couple of dozen ASW choppers aboard the carrier is not the best idea: spotting them on the flight deck (and having them there constantly to guard against sub attack) would mean displacing fixed wing jets from th same spots, with the consequence that the carrier is less effective as a strike carrier (i.e. an own goal).
-The simple expedient of a helicopter flying from an escort rather than the carrier can significantly decrease the time it takes for that chopper to get to the sight of the contact (i.e. the escort should be closer than the carrier) and therefore substantially improve the chances of sinking the sucker. It also means that you're keeping the carrier's deck free for fixed wing flying. It also means the carrier can set a defensive course rather than having to manouver to hunt the sub.
-Mr Page is, of course, ignoring the utility of TAS and hull mounted sonar in all of this, i.e. without escorts your not going to have them.
However, I do happen to agree that helicopter numbers and airborne radar are important. In the case of the latter, you may just convince a less experienced sub driver to keep his head down and you may get lucky and catch a contact too. Of course, the high fidelity horizon search radars coming into service (i.e. SAMPSON) will also be pretty good at this too. Helicopter numbers is a bit more tricky: having the numbers to swamp a contact is both useful and important, but you have to allocate the required helicopter numbers sensibly, and sticking them all on a strike carrier isn't a bright way to do things. For my own part (and this is treading old ground) I reckon that sticking perhaps 3-4 aboard the fleet ASW escorts (and the carrier too) is the best work-around: it brings the numbers up, doesn't make the escort too unwieldy (i.e. it can still be DDG sized rather than CVS sized), and the RN may actually be able to supply enough birds to fill such escorts (i.e. there aren't enough Merlins to provide 4 6-Merlin flights, there might be enough for 5 3-Merlin flights).
Importantly though, any move to increase aviation potential shouldn't come at the expense of other core-ASW capabilities: it still needs to be silenced, it needs a good sonar suite etc. Otherwise, what you'll be left with are ships that are useless in bad weather being unable to operate their big choppers and unable to act as an escort.

He was an MCM diver IIRC. And yes, he did get turned down for promotion, or certainly that's the scuttlebutt.
