The Single Integrated Operational Plan (SIOP) is a blueprint which specifies how American nuclear weapons would be used in the event of nuclear war. At NATO level, an agreement to use nuclear weapons envisages the United Kingdom participating in the SIOP. The plan integrates the nuclear capabilities of the "triad" of bombers with intercontinental range, land-based intercontinental ballistic missiles (ICBM) and sea-based submarine-launched ballistic missiles (SLBM). The SIOP is a highly classified document, and has been one of the most secret and sensitive issues in U.S. national security policy.
