Nuclear Attack Warning: Military Preparedness and Response Time
ICBMs are detected within seconds via satellite IR sensors, with 15-30 minute total response window. SLBMs reduce warning to 5-10 minutes. The president has sole US nuclear launch authority.
In a nuclear attack scenario against a major power like the US, the military is not caught off guard. ICBM detection and response involves multiple layers: - Satellite-based infrared detection spots launches within seconds of ignition - Ground-based radar (PAVE PAWS, Cobra Dane) tracks trajectories within minutes - NORAD processes the data and confirms the threat - Total detection-to-response decision time: approximately 15-30 minutes for ICBMs SLBMs (submarine-launched ballistic missiles) from closer range reduce warning time significantly — potentially to 5-10 minutes for coastal targets. The president has sole authority for nuclear retaliation in the US system. The "nuclear football" (Presidential Emergency Satchel) contains communication equipment and authentication codes, not a literal launch button. Launch orders are transmitted through the chain of command to missile crews. For civilians, warning time depends on location and attack type. Civil defense sirens and the Wireless Emergency Alert system provide minutes of warning at best for ICBM attacks.
