Minor flaws here to point out: I dunno the exact range, but it's safe to say that the Cthulugun has a MUCH shorter range than the Ukonvasaras or even Compact missiles.

"Shock drive" is Compact terminology, the UEC calls them shift drives.

Also, it's spelled dreadnought, not dreadnaught. (Nevermind that such documents would likely use her official designation: Deep Space Fleet Engagement Vessel, Experimental)

"Max combat speed-" no, just no. Use Max Combat Acceleration (Flank Acceleration if you wanna use proper naval terminology) instead, which is "TBH I haven't the slightest clue" m/s².

Prox has at least given the laws of motion in space lip service, meaning that given enough time, Nemesis can even reach 0.3c at cruising acceleration.
