Gathering info on this long-defunct organization, we came to conclusion they got closed down by Star Gods quite possibly as a response to tampering with Shadowtech; clues are given both by history and by the UAC legacy surviving to this day, for good or worse. If this connection with Shadowtech is indeed true, we might be able to find a few yet-undiscovered UAC bases, most likely located deep underground, thanks to our Hyperwave Mystycism.
