Purpose.

The purpose of the Air Force Nuclear Weapons Surety Program is to incorporate maximum nuclear weapons surety, consistent with operational requirements, from weapon system development to target or dismantlement. This instruction implements positive measures to prevent unauthorized activation of critical functions, including unapproved or inadvertent authorization, prearming, launching, releasing, arming, and targeting, and protect against inherent risks and threats, and to ensure components are compatible with the assembled nuclear weapon system.
