I have a question.
Viewed as a cruiser, the UEC Sanctus is quite impressive. It has decent point-defenses, relatively heavy armor, and a good amount of firepower. At close-range, the Sanctus can destroy a Fenris, Leviathan, Hyperion, and even a Deimos. However, the Sanctus is almost as large as a corvette (and its table classifies it as one), and it lacks the armor and extreme resistance to light weaponry that actual corvettes have. When you consider its size (and therefore cost) the Sanctus seems much less powerful.
Now, the Sanctus's tech description says that the Federation built it with enough cargo space to double as a military freighter. I imagine that this accounts for its large size. This makes sense when I consider that the Feds weren't expecting to fight a war, but it still seems like a poor choice. I'm not an expert, but I'd guess that without the large cargo bay, the Sanctus could either be built smaller or built into a true corvette. So, why did the UEF design it that way?
I don't presume to know everything about Blueplanet. There may be some other reason for the Sanctus's size, and I can imagine that BP's writers might have wanted to avoid making the Sanctus as powerful as a Chimera or Bellerophon (since the GTVA is militarily superior to the UEF), or as cheap as a Hyperion. Again, I'm not insulting the mod. It just seemed a little strange the the Federation Navy would limit the Sanctus's effectiveness in that way, even with their Ubuntu philosophy.
