Redwire has announced that it has successfully completed critical design review (CDR) for ELSA solar arrays for an undisclosed national security program in low Earth orbit, through a contract with Moog Inc. This milestone paves the way for manufacturing and integration with Moog Inc.’s METEOR satellite bus.
Through a contract with Moog announced in March 2026, Redwire is responsible for the system design, manufacturing, testing, and flight hardware delivery of the ELSA solar array wings. ELSA has also been baselined by Moog as a standard component of its METEOR ESPA-Grande satellite bus. The bus is all-orbit capable and supports a wide variety of missions and flight profiles, including pathfinder constellation missions and other disaggregated architectures.
The CDR confirmed that ELSA’s design has undergone a rigorous and detailed assessment and is in full compliance with customer requirements for the program.
ELSA is designed for customers who need to minimise solar array stowed volume and mass while remaining competitive with conventional solar array performance and pricing. The solution provides 50 percent more power by volume than traditional solar arrays. Engineered for volume production, ELSA offers a step function improvement in modular, scalable design and rapid turnaround to drive down cost and improve delivery times.
Redwire is a market leader in space power solutions, with a proven track record of innovation and on-orbit success. Redwire-built solar arrays have a 100 percent on-orbit success rate on flagship space missions including the International Space Station and NASA’s Double Asteroid Redirection Test mission.
