I've been thinking about some ships of a more tactical advantage than just mass fire power, every fairly design ship will have a way of being defeated, so I came up with some ideas.

This is the Aegis, it is designed to create an area of safety for other ships, slow moving and with not much in the way of attack. It can heal, shield and protect other ships with its large anti weapon system. the ship itself is not too flimsy either.

This one is called the Broadside, it has no forward facing weaponry to speak of, but instead is used to destroy flanking units to avoid side and rear attacks, anything that tries to slip by your fleet will be shot to peices, leaving the rest of the ships to concerntrate on the enemy infront of them.
Best not ysed in a direct fight as it can be a bugger to target with.

One of my weirdest designs, the Bypass has only rear facing lasers, but more than enough to take a big chunk out of something. The idea behind this ship is that it flys past its target completely, and once past it doesn't have to turn to fire, leaving the enemy ship completely open for a nasty attack, great against front shielded ships. It moves pretty damn fast but has a slow turning circle, the idea being to get behind as fast as possible taking as few hits as you can.

Finally the scattershot, not as much tactical thought on this one, small damage weapons that cover a wide area doing damage to large groups at once, if the scatter shot survives long enough its great at taking out groups, but its isnt particularly strong, so it does tend to fall apart if left undefended.
Screenshots will follow when I can, yes they are damn ugly, but they are functional.
