Cold Fire Prevention (CFP) applies to which missile model?

• A. PAC-3 MSE
• B. PATRIOT PAC-2
• C. THAAD
• D. PATRIOT PAC-3

Answer: (A)

Cold Fire Prevention is a safety feature tied to the interceptor’s ignition and arming logic, designed to prevent any uncommanded or accidental ignition under cold-handling or storage conditions. The PAC-3 MSE version includes this prevention measure due to its propulsion and electronic arming design, which required an added safeguard to avoid inadvertent ignition in cold environments or during transfer and storage. The other interceptors in the Patriot family (PAC-2, PAC-3) and similarly external systems like THAAD use different safety architectures, so CFP is not part of their standard fielded design. That’s why the PAC-3 MSE is the model associated with Cold Fire Prevention.
