Space and Missile Defense (SMD) provides acquisition, programmatic, and in-depth technical, engineering, integration, and resiliency support space systems to include space-based positioning, navigation, and timing systems program components, such as the Global Positioning System (GPS) space segment, the ground operational control segment (OCX), and Military GPS User Equipment (MGUE) and related technical architectures. SMD also supports space control activities to include space domain awareness, space controlrelated command and control, offensive space control, defensive space control, and mission assurance, as well as provides support for space launch acquisition to include small, medium, and heavy launch programs in the National Security Space Launch (NSSL) mission area.


Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance (C4/ISR) goes beyond fielding platforms and transporting intelligence data: it is the fusion of intelligence products to provide battlespace awareness in support of cooperative engagement designed to counter the strategic means, operational plans, and tactical methods employed by our adversaries.


Strategic Deterrence and Capability (SDC) serves as the focal point for nuclear modernization acquisition programs and portfolio. This includes the Ground Based Strategic Deterrent (GBSD), Long Range Stand Off Weapon (LRSO) and the B61-12 Tail Kit Assembly programs; portfolio assessments including the COLUMBIA, B-21, and F-35 DCA programs; and sustainment of legacy nuclear TRIAD systems (e.g., Minuteman-III). SDC is also responsible for ensuring DoD programs comply with U.S. strategic treaty obligations.


Nuclear Command, Control, and Communications (NC3) delivers advice to the Secretary of Defense on policy, direction, Congressional engagement, and Milestone Decision Authority on select NC3 programs to facilitate presidential command and control of nuclear forces. Effective nuclear deterrence demands an assured, resilient, and reliable NC3 system that performs critical functions including situation monitoring, planning, decision making, and force direction and management. The NC3 System must ensure timely and cost-effective fielding, end-to-end capability, and advancement to stay ahead of evolving threats.
