Speed. Delivery. Agility.

Recognized as the Department of Defense's constructive disruptor for space acquisition, the Space Development Agency (SDA) will quickly deliver needed space-based capabilities to the joint warfighter to support terrestrial missions through development, fielding, and operation of the National Defense Space Architecture. SDA capitalizes on a unique business model that values speed and lowers costs by harnessing commercial development to achieve a proliferated architecture and enhance resilience. SDA will deliver a minimum viable product - on time, every two years- by employing spiral development methods, adding capabilities to future generations as the threat evolves.



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



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.



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



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.




SDA’s Emerging Capabilities (EC) Cell provides a foundation for new mission concepts that deliver quantifiable warfighter benefits. EC will transition technologies and capabilities into future tranches by working closely with the military services and DoD research community to fly and evaluate select experiments and assess their potential to enable mission accomplishment.




The Navigation Layer will establish a GPS-independent navigation capability for the National Defense Space Architecture (NDSA) using optical inter-satellite ranging, and optical space to ground links.




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



Two Military Satellites Just Communicated With Each Other Using Space Lasers

Date: May 19, 2022 | Outlet: Gizmodo | By: Passant Rabie Two satellites recently exchanged more than 200 gigabits of data over a distance of about 60 miles (100 kilometers) using laser communication in space. The achievement sets the stage for yet another satellite constellation. Satellites generally don’t communicate directly with each other. Instead, they…
