Thank you for the feedback and the tips.
I started using the "Planes" you were speaking of. After I was done morphing it to fit, I added a "shell" modifier and Chamfer.
I also slimmed the large plates a bit, put them a little further up and added more of an angle to them.
I also added a smooth on the front of the large plates on the side. I pulled up the bottom of the ship as there is a whole other level at the bottom I will add separately.
** Edit **
This is still just the blockout but tips and tricks are always welcome.
