The problem is that the Sathanas has way too few weapons, on the hull, they are mostly AA, except for the LRED, the ship is just not designed to be attacked, its more, "go there, blow up stuff fast, jump out", like the Lucifer.
If you plan any attack on them its easy, just do not attack it from the front, the Colossus is harder to kill.
As for the Hippocrates, they definately designed to aid in convoy escort, 2 of them can easily kill a Cain, 3 of them can bring a Rakshasa down to 50%, its not like you gona send them to the front lines, but they can help a lot.
