Launch on warning (LOW), or fire on warning,[1][2] is a strategy of nuclear weapon retaliation where a retaliatory strike is launched upon warning of enemy nuclear attack and while its missiles are still in the air, before detonation occurs. It gained recognition during the Cold War between the Soviet Union and the United States. With the invention of intercontinental ballistic missiles (ICBMs), launch on warning became an integral part of mutually-assured destruction (MAD) theory. US land-based missiles can reportedly be launched within 5 minutes of a presidential decision to do so and submarine-based missiles within 15 minutes.[3]
