Remember, Droid, that Anemoi vessels are designed to serve as mobile installations. They can house enough supplies and equipment to sustain an entire fleet for several months. This is how the Temeraire was able to get itself repaired completely within the space of two short missions, or a few days + 15 minutes at best.
It is also worth noting, however, that the 14th fleet's misadventure to Sol, despite lasting only a couple of weeks, was able to severely drain the two logistics vessels that tagged along. Considering that the entire fleet was almost completely sustained by these two ships alone, against an entire Shivan armada led by the biggest monstrosity that the Shivans have shown (off), this is a testament to just how much (hyper)space there is in those vessels. At the same time, it also highlights the fact that the Anemoi is not a replacement for stationary installations.
