Heh? The Hippocrates? Weakly armored?
Its got more HP than a Fenris which is basically an armored block.
The hippo is tough.
But I still like the exposed look - it's awesome.
Its LTerSlash is probably there because it was also designed to evacuate civilians and treat wounded military personnel, often near the field of battle where a stray cruiser may come around. The Hippocrates we see in the game are probably all owned by the military. A civilian one (if there are any) probably wouldn't have the anti-warship beam cannon.
The Argo doesn't have heavy armament because part of its role is as a marine boarding craft. Its only going to dock with a ship which is pretty much disabled and disarmed, meaning it doesn't
need heavy armament at all.
I think it probably has the beam to fend off pirates in the like. Undefended military transports are unlikely to be carrying anything important. An aircraft carrier sized hospital would be an attractive target.
And that.
