Raufbold no i tested it out against 2 death stars (standard), 2 subjugators (standard), 4 munificent class (B) (standard), 4 of my custom munificent (B), and 30 of my personally modified LAAT Gunships (which have shown effective at damaging this bastards shields without support from the rest in a side-test)
so from my personal experience this ship was nearly invincible,
IvanBerni your ship was quickly decimated with the Torpedos
i wasn't counting on torpedoes though, i'll have to see if i can stop the torps. ALSO note the version of the ship you fought had no engines due to the updating process, the engines were tier 3 anti-grav thrusters from Star Forge Thruster pack. Those square holes in the left and right were where the engines were before the update.
i think it needs point defense
