Sanctuary would be the next level up. A GTL would be best used as part of a (rag-tag/migrant) fleet keeping ships from falling apart. Sanctuary is meant to do everything (fuel processing, mining, food production) by itself, forever alone.
Yeah, though the Sanctuary doesn't seem to be as capable at effective/efficient repairs for
other warships, or for storing lots of munitions/replacement parts on the level of a battlegroup (though I guess swapping out the cryo-stasis sections for those functions would solve that problem).
So I guess that whereas the Sanctuary is fully self-sufficient (if less effective against craft than a single Aeolus, and hardly any anti-ship capability to speak of), destroyer-sized vessel, the Anemoi is not self-sufficient but far more capable at servicing an entire battlegroup at a rapid pace for an extended time period (but far from indefinitely, especially in prolonged intense action). One is a much better asset for war and shorter-but-intense operations while the other can maintain a slow jog for itself and a few smaller ships for decades.
An overwhelming force?
I got the impression that MORPHEUS is all about resisting the Shivans or Vishnans on a subspace/Nagari level, or countering a vulnerability in that area.
Remember, Steele's mindset/frequent thought in 'Ken' is "They sneak in through your dreams ... they can't get in if you shut them out" [approx.]; coupled with the unusual, year-long period of total silence from the Vishnans in Sol (with the Elders/UEF, as well as the Tevs), it seems like a Nagari-cancelling/jamming capability of some sort is in the works. Chances are that it would (in the near-future, at least) only work on a general, large scale (where it doesn't completely block all Nagari stuff, but severely curtails it and, in a sense, 'blockades' it in a given system.
And IIRC, Morpheus was the god of sleeping/dreams. I don't recall a specific mention about
passing away in one's sleep.
