                      OVERSIGHT OF

                      THE DOD NUCLEAI

                      ENTERPRISE




Comprehensive oversight of DOD's nuclear enterprise is crucial for supporting nuclear
deterrence missions, as the department undertakes triad modernization efforts that are
unprecedented in scope. DOD has limited room for errors or schedule changes as it
undertakes these efforts. GAO has identified oversight challenges and made multiple
recommendations to address them, but many recommendations remain unaddressed.

Following are examples of planned triad modernization efforts that GAO has reported on:
-'Ihe Sentinel land-based missile system is intended to replace the Minuteman III system
  in 2030-50  years past the Minuteman III's initial planned service life.
  - 'The Columbia-class ballistic missile submarines are intended to replace the Ohio-class
  submarines beginning in 2027, the Ohio's service life having been extended from 30
  years to 42 years.
  -'Ihe B-52 bomber-in service since the early 1960s and well past its original planned
  service life-is intended to get, among other modifications, a full engine replacement.
  - B-21 bombers are intended to replace B-2 bombers-in service since the mid-1990s-
  beginning in the mid-2020s.

DOD   has significantly modified its nuclear enterprise oversight structure multiple times
since 2021, putting oversight continuity at risk and potentially affecting senior leaders'
ability to make informed decisions. In 2014 DOD established a group to ensure the long-
term health of DOD's nuclear enterprise by addressing issues identified in the 2014 nuclear
enterprise reviews. In 2021 DOD replaced that group with another group that would
assume the same responsibilities. According to DOD officials, DOD replaced the second
group with a nuclear-focused Deputy's Management Action Group in 2022.

GAO   maintains that its recommendations to strengthen DOD's nuclear enterprise
oversight are valid, especially in light of the significant and continual modifications to the
oversight structure. For example, GAO's recommendations that DOD establish oversight
roles and responsibilities and methods of communication and coordination remain relevant
for whatever group is responsible for overseeing DOD's nuclear enterprise.
