MODERNIZING THE MILITARY'S SPACE ARCHITECTURE

WHO WE ARE

The Space Development Agency orchestrates the development and fielding of DoD’s future threat-driven National Defense Space Architecture. SDA uses novel approaches to accelerate the military space capabilities necessary to ensure U.S. technological and military advantage in space for national defense.

CAPABILITY LAYERS

TRANSPORT LAYER

SDA's Transport Layer will provide assured, resilient, low-latency military data and communications connectivity worldwide to a full range of warfighter platforms.

LEARN MORE

BATTLE MANAGEMENT LAYER

SDA's Battle Management Layer will provide architecture tasking, mission command and control, and data dissemination to support time-sensitive kill chain closure at campaign scales.

LEARN MORE

TRACKING LAYER

SDA's Tracking Layer will provide global indications, warning, tracking, and targeting of advanced missile threats, including hypersonic missile systems.

LEARN MORE

CUSTODY LAYER

SDA’s Custody Layer will provide 24/7, all-weather custody of time-sensitive, left-of-launch surface mobile targets to support targeting for advanced weapons.

 

LEARN MORE

EMERGING CAPABILITIES (DETERRENCE) LAYER

SDA's Emerging Capabilities Layer will incubate new mission concepts. Initial focus will be to deter hostile action in deep space (beyond Geosynchronous Earth Orbit (GEO) up to lunar distances).

 

LEARN MORE

NAVIGATION LAYER

SDA's Navigation Layer will provide alternate positioning, navigation, and timing (PNT) for Global Positioning System (GPS)-denied environments.

 

LEARN MORE

SUPPORT LAYER

SDA's Support Layer will enable ground and launch segments to support a responsive space architecture.
