Which of the following is NOT listed as a survivability concern for air defense systems?

• A. Cyber attack vulnerability.
• B. Counter-fire exposure.
• C. Maintenance vulnerabilities.
• D. Physical protection.

Answer: (A)

Survivability here is about keeping the air defense system operating under physical threat and disruption—factors that directly affect the device’s ability to stay functional, be maintained, and be protected from damage on the battlefield. Counter-fire exposure, maintenance vulnerabilities, and physical protection all impact whether the system can survive an attack and still perform its mission. Counter-fire exposure assesses how exposed the system is to enemy fire and how likely it is to be knocked out; maintenance vulnerabilities look at how quickly a system can be repaired or replenished when logistics are stressed; physical protection covers armor, hardening, concealment, and other measures that reduce the chance of damage in the first place. Cyber attack vulnerability, while crucial to overall system resilience, falls into the domain of cyber security and information integrity rather than the direct physical survivability of the platform. It affects how data and control are protected and may influence operations, but it isn’t typically categorized as a survivability concern in the same framing as the others. So cyber attack vulnerability is not listed as a survivability concern in this context.
