Equalizer i also tried a "U" shaped design in one of my ships (unfortunately it kept flying diagonally. hahaha.)
the thing i like about U-ship missile kite designs is that it has a crazy amount of missiles, so the opening salvo is usually devastating.
i also like how you created that frontal cover (i never thought of doing that). do the missiles hit the front or do they manage to pass through the gap in the middle? that must have required several testing to get the gap size correctly (nice).
although i don't think you got enough PDs/shields in that design, plus since it doesn't have enough thrusters, fast cannon wall ships (with lots of PDs) can probably deal heavy damage on that ship. edit : (double layered shields : shields at the back of the guns and shields alongside the guns, usually give better defense against splash damage and heavy barrage.) a good way to test if you got enough shields is a head-on collision with the cerberus ship. if your ship survived with very minimal damage after the initial salvos, it means the defense is enough to survive most attacks.
even missile nuker ships like tephra's ship can likely overwhelm the front in the initial salvo. afterwards, the side missiles will get creamed. you could even just duplicate your own ship and check if you can survive your own missile salvos.
