Since we have already quite a lot of armour, why not go full hog with max armour?
I can't find anything non-essential to remove, so sadly I have to make the ship larger to fit more stuff.
520 Dt, Armour 15, MCr 550 (the armour is now the most expensive component)
An extra missile turret.
Free space down to 2 Dt...

It takes 12 weapon damage to shell it, requiring 36 nuke hits, so firing 216 Zho missile bays...
Basically it takes a particle spinal to destroy it. Not bad for 500 Dt...
