maybe not officially in se4, but they can be modded very effectively. maybe if you gave their hulls the emissive armor ability with a threshold of about 150 points of damage. you would have to take them out with capital ships, and they would be almost unstopable in the early game. maybe as they tech up, their newer hulls would have higher thresholds so you would need 900+ damage to hurt them late in the game. you would have to use dreadnaughts with WMGs or PSPs or the like.
