Nuclear Command, Control, and Communications: Update on DOD's Modernization

Nuclear command, control, and communications (NC3) is a large and complex system
comprised of numerous land-, air-, and space-based components used to assure connectivity
between the President and nuclear forces. The current NC3 architecture consists of
components that support day-to-day nuclear and conventional operations prior to a nuclear
event as well as those that provide survivable, secure, and enduring communications through all
threat environments. Though some NC3 systems are specific to the nuclear mission, most
support both nuclear and conventional missions. The Department of Defense (DOD) is
executing several acquisition efforts to modernize elements of NC3.

Since 2013, GAO has released several products related to its review of NC3 as required by
congressional defense committees. For example, the Senate Armed Services Committee report
accompanying a bill for the National Defense Authorization Act for Fiscal Year 2013 included a
provision for GAO to assess Department of Defense (DOD) efforts to sustain and improve the
NC3 system.1 We addressed this provision initially through a report on the Family of Advanced
Beyond Line-of-Sight Terminals in December 2013, and then subsequently issued a classified
report on operational assessments of NC3 in February 2014. We also provided a classified
briefing to the Senate Armed Services Committee staff on the extent to which DOD is
addressing known NC3 gaps or weaknesses and has taken steps to transform the current NC3
to provide improved capabilities in the future.2

This report is in response to the Senate Armed Services Committee report accompanying a bill
for the Carl Levin National Defense Authorization Act for Fiscal Year 2015,1 which included
provisions for GAO to (1) update recent prior assessments of NC3 acquisition programs, and (2)
review the U.S. Strategic Command's ongoing effort to update the Mission Planning and
Analysis System with briefings to the congressional defense committees. 4

To address our objectives, we focused our review on seven NC3 programs or efforts that
support the full range of NC3 functions that pertain to planning, decision making, situation
monitoring, force management, and force direction. Given the large number and wide range of
programs that either directly or indirectly support NC3-related missions, we chose to focus on
key NC3 programs or efforts that are among the largest in terms of estimated cost and/or that
