Who is responsible for determining if a Weapons Systems Safety Rules (WSSR) fault is critical?

The determination of whether a Weapons Systems Safety Rules (WSSR) fault is critical primarily falls under the purview of the System Program Office. This office is responsible for the overall management and oversight of a specific weapon system throughout its lifecycle, which includes evaluating safety-related issues. The System Program Office employs a comprehensive understanding of the system’s design, operation, and risks to assess faults, including their potential impact on safety.

Their role involves not only addressing the technical aspects but also evaluating the implications of any identified faults, ensuring compliance with safety standards, and recommending corrective actions as necessary. The safety assessments conducted by the System Program Office are critical to maintaining the operational integrity and safety of the weapon system.
