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.
