It's a mid sized ship, perhaps 400m long. I'll give an exact number when I scale it. The shuttlebay makes the ship look smaller, but in actuality, it's very big shuttlebay, designed to carry the fighter craft that wil go along with this ship. (Which i have yet to create, but they will be there.)
I added an another torpedo launcher to the aft quarter. There are now are now two launchers on the ventral side, and two on the dorsal side. The advantage of this is that if you lose your dorsal shields (for example), then you're not gonna at risk of losing all your torpedoes in one hit.
