The Spacecraft Engineering Division (SED) designs, builds, and operates pioneering and innovative spacecraft and space systems. The SED functions as a prototype laboratory for new and operationally relevant space based capabilities. From cradle to grave, the division provides expertise in mission design, systems design and engineering, and hardware expertise for every aspect of a space system. The division has a history of transitioning advanced technologies into operations and industry, applying expertise in systems integration, design and verification, dynamics and control systems, electronics and software, and mission operations to develop advanced space technologies.

The SED is a leading expert in spacecraft design, construction, and on-orbit operations. The SED is the focal point for naval spacecraft, and maintains an active, in-house suite of facilities and capabilities to develop satellites from concept to launch and through mission life. The SED has a proven history of integrating multiple complex systems, from research and development, to mission operations, to providing new capabilities. Since 1955, our expansive knowledge of space systems development has included more than 104 spacecraft launches and countless technologies and payloads hosted on other spacecraft missions.
