What kinds of threat conditions drive a shift from normal to casualty CSOSS procedures?

• A. Sensor faults, communications loss, power degradation, weapon system faults, or conflicting data requiring alternate engagement methods.
• B. Only weather changes.
• C. Any change in ship's speed.
• D. Visual sightings without radar.

Answer: (A)

Casualty CSOSS procedures are triggered when a threat or situation makes the normal engagement steps unreliable or unsafe, so you switch to predefined steps that keep safety and mission capability intact. This happens when critical systems fail or data streams are degraded: sensor faults remove trust in target information and require reliance on backups or alternative modes; loss or degradation of communications cuts you off from coordination, necessitating autonomous or conservative actions; power degradation threatens the availability of essential equipment, so you prioritize loads and operate within reduced capability; weapon system faults create safety or reliability concerns, prompting procedures that prevent unsafe firing and guide safe handling; and conflicting data from different sources requires switching to alternate engagement methods or additional verification to avoid misinterpretation.

Weather, a change in ship speed, or visual sightings without radar aren’t by themselves triggers for casualty procedures unless they cause or reveal degraded sensing, control, or safety issues.
