[X] Two Nacelles (Warp 3.6, 15 -> 23 Industry)
We're still got several very important systems to resolve on this ship. Phase cannon numbers and placement, computer cores, torpedo bays... and we're very probably going to need some serious computer core(s) to run all the weapons at peak effeciency.
Also, as has been mentioned many times, this has a decent enough cruise and sprint, and we do have an industry budget we don't want to completely blow after having just finished laying out primary hull and deflector.
