Why do we need 12-14 hour missions?
I can see the need for persistence in ASW operations but for straight marine patrol surely it's the amount of sea you cover in one mission that is important and speed can make up for a lot of wandering about with engines switched off at a couple of hundred knots
If you can't land to pick anyone up most ASR really doesn't need someone turning circles over the "incident" all day every day until the surface fleet turns up
