For every world the Shang bombarded into new dark or ice ages, the New England Federation answered with a dozen secret fabrication plants. Some resided on the outskirts of populated systems, while others operated in truly dark systems where no human lived. Even Post War accounting cannot calculate exactly how many freighters, destroyers, smaller escorts, or fighters they built. The Shang found and destroyed too many of those secret bases for a full accounting to ever be completed. We do not even know how many secret factories existed, since many launched from systems seeking to save as many of their people as possible while Shang bombardment fleets smashed their planets into rubble or worse. The Shang thought they could beat the Federation by hammering it until it broke. They were wrong, and they paid for it.
