And...
There are rumours that the Star League era vessels of the Supremacy have been significantly upgraded. There have been reports of Essex class Destroyers shrugging off hits that should have caused critical damage, of Sovetskii Soyuz cruisers unleashing fire from 4 times their standard Naval Laser Armament, of Mckenna Battleships swatting fighters with impunity and Vincent corvettes shooting down incoming missiles.
Most disturbing of all are the reports of coordination between warships and dropships that defies all logic. Accurate long range fire from vessels, almost as if the dropships were acting as spotters.
Utmost caution is advised in any encounter with a Supremacy Warship, such vessels should be engaged with odds of 2:1 or better.
THE TRUTH: over the centuries, as vessels were repaired, they have been improved. When armour was replaced, it wqs thickened (to the point of now mounting Double their SL era levels). Fighter scale and point defence weaponry has also been incorporated. Most significant of all was the development of Warship grade C3 systems. Based on the networking systems of the SDS system, the C3 network allows far more effective coordination between Warships and their escorts.
Yes, I know in the OTL, the DC developed C3, but it fits with the TS and SDS tech...
