it's actually just a small tritonish sized repair vessel in dire need of a HTL facelift and a retexture.
i made it ages ago, before i could do much in the way of modeling. it is actually a very poorly implimented model atm compared to my current ones, but i havn't found the time to fix it just yet - got another fairly important vessel to build first.
it is second on my priority list tho.
the idea behind it is that it can carry spare parts and repair crews to a damaged ship very quickly (3 banks of powerful engines), and can tow anything below cruiser size out of the battle if need be. not really a mobile shipyard tho. basicly just a support ship for capital vessels.
and as for being a hard target, well, not really - the yellow circle thing at the back is the small secondary dockpoint, and the other one is just a little AAAF.
it more relies on it's speed and medium armour to keep it out of trouble when on it's own, and the firepower of the ship it is docked with when it is towing something
