Oh man, the missile pod is the top? Speaking from an interceptor's perspective, if I get above this ship you can't touch me, and as soon as my guns drop the shields, I'm firing directly into a big pile of BOOM. Unless this thing has some serious speed and maneuverability, or a major escort, it's prone to be toast.
Oh, don't worry, this thing isn't skimping on armor or shields. The pod would definitely be heavily armored. The turret cover was never a problem in an in-game sense, and realistically, it would only take a short roll to broadside incoming fighters with your turrets. And as a bomber, it would be well escorted.
