Is spaceship armor useless?

That one doesn't make sense. A Tertiary battery on SM+10 does 2d dDamage. Even an SM+4 craft has a mere 3 dDR per layer of Nanocomposite. Anything remotely 'heavy missile'-sized will be toast, and anything fighter-sized is worthy of a micromissile hit. And it can't have PD, because then it has less armour, and with less armour it will be shredded by PD.
