Chalybs Defense Solutions

Chalybs Defense Solutions is a human manufacturing company. The company developed and manufactured the M808 "Scorpion" and the M850 "Grizzly" main battle tanks. They were contracted by the Office of Naval Intelligence to manufacture the M145D "Rhino" artillery vehicle, which was based on the ONI-developed Zeus 320mm plasma cannon, and to manufacture the Operator armor for the Beta-5 Division's Asymmetrical Action Group. Chalybs also developed the standard-issue pilot helmet for the UNSC Air Force. Both armor systems were tested at the Chalybs Testing Preserve.
