Is spaceship armor useless?

And it can't have PD, because then it has less armour, and with less armour it will be shredded by PD.

What if you build it with armor on the front, and PD in turrets in the middle? The target isn't going to get a chance to engage the 'missile''s side or rear armor. PD batteries impinge on the ability to maximize the return from high-density design but other that that?
