The document describes a new marine armor system that provides anti-piracy protection for ships. The system hardens the ship with ballistic steel alloys and can secure all doors, windows, and accesses with the press of a single button by one crew member in just 10 seconds, making it much faster and safer than traditional armoring methods. It is designed to help crews safely muster in a citadel area while blocking access to other parts of the ship during emergencies.
