We haven't had 3 AORs since the late 90s, and we frequently had periods where there was only one AOR of the two available (or none, before they were both paid off). It's not really a big deal, and we don't have enough of a mix of assets to operate one TG on our own, let alone two.
It would be nice on paper, but if it means the crews never get any non-deployment time because we would have 2 crews spread between 3 ships, just makes retention worse. I think two oilers is enough for our pretty limited resources, and unless we figure out our recruitment/retention not really sure how we would keep the CSCs, AOPs and JSSs going at the same time anyway under the existing numbers of ships, let alone adding on more hulls. :dunno:
Then again the people that want more hulls also don't like planning work periods that are long enough to actually get the planned maintenance done (let alone the major corrective maintenance required for 25 year old hulls) or doing things like load leveling the schedule so that the entire fleet isn't in a work period at the same time, so not really holding my breath. Does make coastal postings a bit less appealing though; as much as I like hands on work don't feel like volunteering to be Sisyphus.
