The US Air Force last week updated its guidance on the command and control of nuclear weapons to include protection against electromagnetic pulse and cyber attack, among other changes. See Air Force Nuclear Command, Control, and Communications (NC3), Air Force Instruction 13-550, April 16, 2019.
“This is a complete revision to the previous version of this instruction,” the new guidance states. “It revises the command relationships, roles and responsibilities, the governance structure, and addresses resourcing, architecture and configuration management, resilience, and assessments.”
“Resilience” here pertains particularly to “two of the most broadly applied challenges: hardening against the effects of electromagnetic pulse and threats in the cyberspace domain.” These topics were scarcely mentioned at all in the previous version of the Air Force Instruction that was issued in 2014, nor did the term resilience appear in the earlier document.
Several new classified directives on nuclear command and control have been issued in recent years (such as Presidential Policy Directive-35 and others) and their content is reflected at least indirectly and in part in the new unclassified USAF guidance.
A broader modernization of the nation’s entire nuclear command, control and communications system is underway at U.S. Strategic Command, costing a projected $77 billion over the coming decade. See “STRATCOM to design blueprint for nuclear command, control and communications” by Sandra Erwin, Space News, March 29, 2019.
To empower new voices to start their career in nuclear weapons studies, the Federation of American Scientists launched the New Voices on Nuclear Weapons Fellowship. Here’s what our inaugural cohort accomplished.
Common frameworks for evaluating proposals leave this utility function implicit, often evaluating aspects of risk, uncertainty, and potential value independently and qualitatively.
The FAS Nuclear Notebook is one of the most widely sourced reference materials worldwide for reliable information about the status of nuclear weapons and has been published in the Bulletin of the Atomic Scientists since 1987. The Nuclear Notebook is researched and written by the staff of the Federation of American Scientists’ Nuclear Information Project: Director Hans […]
According to the National Center for Education Statistics’ August 2023 pulse panel, 60% of public schools were utilizing a “community school” or “wraparound services model” at the start of this school year—up from 45% last year.
