Defense Nuclear Enterprise: Systems Face Sustainment Challenges, and Actions Are Needed to Effectively Monitor Efforts to Improve the Enterprise
Fast Facts
DOD conducted several reviews of its nuclear forces. We looked at DOD’s progress in implementing recommendations from those reviews. We found that DOD has implemented some recommendations but doesn’t keep information on its progress current and complete, e.g., expected completion dates aren’t updated for items that are behind schedule.
We made recommendations to help DOD better track its progress on implementing recommendations.
In addition, DOD and the military services are struggling to sustain and maintain aging nuclear weapon systems, e.g., some submarine parts that were never intended to be replaced have failed.

What GAO Found
The Department of Defense (DOD) continues to make progress in implementing recommendations to improve the nuclear enterprise. These recommendations stemmed from DOD's 2014 internal and independent nuclear enterprise reviews, a U.S. Strategic Command 2014 memorandum, and an internal DOD 2015 report on nuclear command, control, and communications (NC3). Since GAO last reported—in November 2018—an additional five of the 247 sub-recommendations from the 2014 reviews have been closed; 91 remain open. In that time, DOD has also closed two more of the 13 recommendations from the 2015 review; six remain open. However, the key tracking tools DOD uses to provide visibility on the status of the recommendations do not provide current and complete information. For example, for those items that are behind schedule, many of the expected completion dates have not been updated to reflect when the items are now expected to be completed. The current DOD guidance for tracking the recommendations' status does not include a specific requirement to keep the information current in the tracking tools. Until DOD addresses these issues, it will not have a complete and accurate picture of when tasks are expected to be finished, whether progress is being made, whether efforts have stalled, or if there are other challenges. Ensuring that there is current and complete information regarding enduring recommendations would also help inform DOD's effort to monitor the health of the defense nuclear enterprise.
DOD and the military services are experiencing challenges related to sustainment and maintenance of nuclear weapon systems and have ongoing and planned initiatives intended to mitigate these challenges. All of the systems we reviewed have been operational since before 1998, making these systems at least 22 years old (see figure). The age of the systems has resulted in maintenance and supply issues. For example, the Ohio -class submarine has experienced the failure of parts that were not originally intended to be replaced. DOD and the services have ongoing and planned efforts to mitigate these challenges, such as improving maintenance processes and sources of supply.

Why GAO Did This Study
In 2014, the Secretary of Defense directed two reviews of DOD's nuclear enterprise. These reviews made recommendations to address problems with leadership, organization, investment, morale, policy, and procedures, as well as other shortcomings that adversely affected the nuclear deterrence mission. In 2015, DOD conducted a review focused on NC3 systems, which resulted in additional recommendations to improve NC3.
The National Defense Authorization Act for Fiscal Year 2017 includes a provision for GAO to review DOD's processes for addressing these recommendations. This report addresses the extent to which DOD has made progress in (1) the implementation and tracking of the recommendations from the 2014 and 2015 nuclear enterprise reviews and (2) addressing sustainment and maintenance-related challenges and planning for the continued sustainment and maintenance of existing defense nuclear enterprise systems. GAO reviewed documents and interviewed DOD officials. This is a public version of a classified report that GAO issued in October 2019. Information that DOD deemed classified has been omitted.
Recommendations
GAO is making two recommendations for DOD to update guidance to require DOD components to keep information on recommendations current and complete. In written comments on the classified report, DOD concurred with these recommendations.
Recommendations for Executive Action
| Agency Affected | Recommendation | Status |
|---|---|---|
| Office of the Secretary of Defense | The Secretary of Defense should ensure that the Director of CAPE, in coordination with the Deputy Assistant Secretary of Defense for Nuclear Matters, the Deputy Assistant Secretary of Defense for Nuclear and Missile Defense Policy, and the Joint Staff Deputy Director for Strategic Stability, as co-chairs of the Nuclear Deterrent Senior Oversight Group, update the applicable guidance for methods of tracking and evaluating progress on implementation of the recommendations from the 2014 nuclear enterprise reviews, requiring DOD components to keep information—including any revised time frames—current. (Recommendation 1) |
DOD concurred with our recommendation and stated that the Nuclear Deterrent Senior Oversight Group co-chairs or, as necessary, the Deputy Secretary of Defense as the chair of Nuclear Deterrent Enterprise Review Group (NDERG), will update the applicable guidance to ensure that time frames and other information associated with planned actions are kept up to date. In April 2020, the Deputy Assistant Secretary of Defense for Nuclear Matters issued a memorandum requesting that all DOD Components with open recommendations from the 2014 reviews update their respective corrective action implementation plans, including timelines for milestones and delivery of metrics by June 2020. Subsequently, in 2021 and 2022, DOD components updated information within the department's tracking tool. These actions-DOD components continuing to update the information beyond the June 2020 deadline in the memorandum-supports the views of DOD officials that the April 2020 memorandum established guidance to the components that continued beyond June 2020. The issuance of the April 2020 memorandum coupled with the continuing efforts by DOD components to keep information in the 2014 nuclear enterprise review recommendation tracking tool current will aid senior leadership in maintaining oversight of the department's progress, and these actions meet the intent of GAO's recommendation.
|
| Office of the Secretary of Defense | The Secretary of Defense should ensure that the Under Secretary of Defense for Acquisition and Sustainment updates the applicable guidance for methods of tracking and evaluating progress on implementation of the recommendations of the 2015 NC3 report, requiring DOD components to keep information—including metrics for measuring progress and outcomes as well as any revised time frames that may extend out more than 1 year—complete and current. (Recommendation 2) |
DOD concurred with our recommendation and stated that the DOD Chief Information Officer and, as appropriate, the Under Secretary of Defense for Acquisition and Sustainment as the NC3 capability portfolio manager, will update the applicable guidance to ensure that metrics, time frames, and other information associated with planned actions are kept up to date and complete. Subsequently, the office responsible for this recommendation was changed to the Office of the Under Secretary of Defense for Acquisition and Sustainment when the Under Secretary of Defense for Acquisition and Sustainment was designated the NC3 enterprise capability portfolio manager. As of November 2023, DOD has not issued updated applicable guidance for the recommendations of the 2015 NC3 report.
