Uzidrate I can find no way to feed a three wide ion beam array in front of three shields and no way to get close without either putting another two tiles between sets or offsetting them by nine tiles. Thus, shields have to be removed. Redundancies in the body of the ship have been removed to make space for internal armor. I widened the back slightly to make room for more engines to compensate for the weight increase and lengthened the side prongs to make space for engines in the front, which in turn required a slight change to their tip shape because they otherwise stuck just out of the FTL bubble.
The second can only be fixed by dramatically upscaling it to fit reverse thrust internally, changing its shape to expand the forward space to accommodate reverse engines, or changing its armaments. So the lasers went out for an ion beam and more electrobolts. As is common in my refits of your designs, shielding has to be sacrificed. Also, this time the price went up, which shouldn't be surprising since you wanted increased capabilities.
