The United States and Russia have some 1,800 nuclear warheads on alert on ballistic missiles that are ready to launch in a few minutes, according to a new study published by UNIDIR. The number of U.S. and Russian alert warheads is greater than the total nuclear weapons inventories of all other nuclear weapons states combined.
The report Reducing Alert Rates of Nuclear Weapons is co-authored by Matthew McKinzie from the Natural Resources of Defense Council and yours truly.
France and Britain also keep some of their nuclear force on alert, although at lower readiness levels than the United States and Russia. No other nuclear weapon state has nuclear weapons on alert.
The report concludes that the warning made by opponents of de-alerting, that it could trigger a re-alerting race in a crisis that count undermine stability, is a “straw man” argument that overplays risks, downplays benefits, and ignores that current alert postures already include plans to increase readiness and alert rates in a crisis.
According to the report, “while there are risks with alerted and de-alerted postures, a re-alerting race that takes three months under a de-alerted posture is much preferable to a re-alerting race that takes only three hours under the current highly alerted posture. A de-alerted nuclear posture would allow the national leaders to think carefully about their decisions, rather than being forced by time constraints to choose from a list of pre-designated responses with catastrophic consequences.”
During his election campaign, Barack Obama promised to work with Russia to take nuclear weapons off “hair-trigger” alert, but the 2010 Nuclear Posture Review (NPR) instead decided to keep the existing alert posture. The post-NPR review that has now been completed but has yet to be announced hopefully will include a reduction of the alert level, not least because the Intelligence Community has concluded that a Russian surprise first strike is unlikely to occur.
The UNIDIR report finds that the United States and Russia previously have reduce the alert levels of their nuclear forces and recommends that they continue this process by removing the remaining nuclear weapons from alert through a phased approach to ensure stability and develop consultation and verification measures.

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.
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 […]
