The Admiral’s temporary lab was in the midst of yet another highly productive cycle. Load bearing antigrav drones flew in every direction as they brought their cargo from sector to sector. Recycled and raw materials to shield frames to fully-completed antigrav shields.
Off in the corner, the testing range was still in full swing, blasting antigrav shields in a real-world stress-test. The shields almost always worked perfectly and captured the vast majority of the bullets fired at them.
They only failed when they held more than they could handle and the whole thing short-circuited. There were also the rare cases where the frame itself was struck, and caused the antigrav field to fail or weaken.
In another corner, they were scanned for defects and other flaws. A vast majority were fine, though some held a few odd manufacturing defects. Those were immediately disassembled and sent to be recycled and reprinted.
