Historical Evolution

George Washington leading Continental Army forces at the Battle of Princeton during the Revolutionary War

Cold War Origins

Development of Systematic Military Readiness

The DEFCON system emerged from the need to standardize nuclear readiness during the Cold War, with the Cuban Missile Crisis demonstrating its critical importance.

1959 - DEFCON Established
Nuclear Era
