So I got a bit bored after using my regular ships for a bit, and i had way too much money spare, so I decided to make a giant impenetrable wall of Missile launchers. It ended up being a bit thicker than I wanted, due to it needing a few hundred crew to man all the shields, factories and Launchers, but this is what I ended up with:

It has 20 launchers, allowing it to shoot 60 missiles at an enemy, This pretty much wipes out any professional or amateur Craft, and leaves a giant hole in anything higher. The 18 Shields form a massive wall, making it extremely difficult to damage this craft head on.

Im aware this design is far from efficient, you can see the missile factories i stuck on the ends when I decided symmetry was no longer a focus, but this craft is extremely powerful and fun as an addition to a squad. JUst seeing the Spam of missiles about to rip an enemy in half is hilarious.
Anyway, Thats my Design =P
