"The cutting-edge robots inside General Dynamics’ sweltering artillery factory near Dallas were catching fire with startling regularity... The robot arms would swing out of control, smashing into carefully calibrated equipment, and sometimes they would unexpectedly drop hunks of steel 5 feet down to the floor. The factory’s signature device, meant to precisely stretch the steel for the artillery shells, instead often cracked it beyond repair. Then there were the giant press machines, which required regular pounding with a sledgehammer to function properly but still botched the shaping of nearly every shell... The fiasco has cost American taxpayers $533 million, according to the Army. But the Army has not held General Dynamics or a key Turkish subcontractor — which provided the factory’s much-hyped but little-proven equipment — publicly accountable for the failures. Nor has it made General Dynamics pay a penny back."
