Next set of questions I have been curious about but not quite sure how to word it.
Does each squadron have multiple block I, II and III a/c?
Or is it each squadron has only common block a/c so in turn certain squadrons have a monopoly on Air Ambulance because they are the only ones with Block II Air Ambulance, while the next squadron is mainly Block IIb so it will be a ASE squadron, and another with Block III so it is going to be a CVN CSAR/Strike mission.
Also, if I have read everything correctly certain squadrons are expeditionary squadrons while other are CVN squadrons. Is that correct? If so, is it common knowledge which are the CVN and which are the expeditionary?
edit: Bevo answered a few of those questions while I was typing my post
Back in the day, there used to be HC and HS squadrons. HC became HSC Expeditionary (Exp) and HS squadrons are going to become HSC Air Wing (CVW). HSC (Exp) is detachment based, sending out Gator SAR dets and USNS Vertrep dets. They also encompass some of the cats and dogs of the Navy helo world, including logisitics support out of Naples and Bahrain, recent humanitarian dets of Mercy and Comfort, and Air Ambulance. Naples and Bahrain are owned by two seperate east coast HSC squadrons. Air Ambulance is a west coast thing and they have some sort of rotation set up between the squadrons out there, not too sure how it works. HSC (CVW) goes out with the carriers and does air wing stuff, like CSAR, strike, ASUW, SAR, etc.
Eventually, HSC will also add OAMCM for organic mine hunting to its capability list. I know the initial idea was to have a det on LCS-1, but this has yet to come to fruition. I'm unsure if this will only be the mission of Exp squadrons, or CVW as well.
ASE=aircraft survivability equipment. Different types of countermeasures allow you to operate an aircraft in different threat environments.
I believe the plan is for each squadron to have a mix of birds, but don't know too much about it. My squadron has a bunch of Blk Is and a few Blk IIs for long range logisitcs.
The VERTREP pic that HJ put up above is of either a IIb or a III. You can tell by the lumps on the nose for the ASE gear and the trapezoidal mounting point on the tail for the CMDS buckets.
Right now, there's only one CVW squadron, HSC-8, which is the squadron in the pictures. As more birds come off of Sikorsky's line, the old HS squadrons will trade in their F/Hs for 60S. All the expeditionary squadrons have a two digit identifier beginning with a 2...such as HSC-21, 22, 23, 25, 26, 28. The reserve squadrons have an 8...HSC-84, 85.
The idea is that 60S pilots can transition between the two types of squadrons. You could do a JO tour at an Exp squadron and then go do a DH tour at a CVW squadron. One of the old DHs at my squadron (exp) recently screened for command of a CVW squadron.
