@SynixMan I just felt like I came off the top rope with a douchy people's elbow of self righteousness after re-reading my post. You're totally right about the need for some type of maritime asset to be ready to handle the alert initially in an emergent type situation. Whether that's the Navy or Marines I haven't the knowledge to touch the topic. Enough about CSAR.....
I think the historical bit that should piss off Navy helo guys is the tanker war of the 80's. Mainly that somehow the need arose for Army helos to base off floating things.
Do you guys have a document that your combatant commanders list what missions they want you guys to be good at in priority order? Yes, that's a serious question, I have no fucking clue how the Navy works.
Most of the issues from the tanker wars are no addressed by organic assets. Rs and/or R/S teams can move about and work low threat targets, if needed, and if not, the Rs (and to some extent, the S) can send in fast movers to go after larger/higher threat targets. The R also provides some pretty substantial ISR/SSC capability over and above an E-2 that's overhead, so keeping track of who and what has been greatly improved.
There are documents for various theaters that spell out even more specific tactics in the maritime environment. Those then drive (among other things) what a squadron trains to and their readiness.
By the way, what is EWS? Your APR?
. I'll talk LHD because that's what I know. Standard LHD sets are 2 to make 1. Which means you MAY have two working helos. One is fragged for Marine SAR support during the entire air plan. the SAR bird lifts first and lands last. LHD NATOPS requires that the SAR bird be within 10mi of mom at all times. CV NATOPS allows the SAR bird to be within 20mi during the day, 10 at night. We'd occasionally allow SAR to go beyond 10 if it was a light day, no troopers over water, etc. so, if the other bird is up they can form up and train within 10mi of mom. The configuration of the SAR bird is limited by its need to be SAR capable. We generally said they could only carry four pax or have the GAU on the left side only. If there's only one SAR bird they can run through some hellfire sim mode if the bird is properly configured or do practice SAR scenarios or instrument prof. If there's a big launch/recovery or FW ops in process SAR was confined to the actual STBD delta.
