Actually, none of the researchable hulls are in the retrofit lab. I have researched all  hulls, but my only possible hull retrofits are Battleship and HHA which are blueprint hulls. Hammerhead A or B, blueprint hulls are retrofittable but the researchable Hammerhead is *not* retrofittable.

I don't think there are any plans too add researchable hulls to the retrofit lab.
