October 30, 2026 — ESI Motion Inc. has officially announced that it is supplying its advanced Solar Array Drive Electronics (SADE) to aerospace and defense giant Lockheed Martin. The critical hardware will support Lockheed Martin’s ongoing development efforts for the Space Development Agency’s (SDA) highly ambitious Proliferated Warfighter Space Architecture (PWSA) programs.
Under the terms of the new agreement, ESI Motion’s specialized SADE technology will play a foundational role in bolstering the SDA as it continues to design, build, and deploy the multi-layered network making up the PWSA. As the landscape of modern defense increasingly pivots toward the final frontier, maintaining robust, resilient, and responsive infrastructure in Earth orbit has emerged as an absolute necessity for global security.
Defending the nation and its allies in space has arguably never been more important or complex. The Space Development Agency’s PWSA programs are engineered to provide the United States military with an interconnected, highly resilient network of spacecraft operating in low Earth orbit. This vast constellation is designed to deliver secure, low-latency communications, persistent global missile tracking, and comprehensive space-based tactical support. By integrating these capabilities into a cohesive architecture, the Department of Defense aims to ensure that troops in the field and commanders alike have access to the latest, most reliable technology available, no matter where they are deployed across the globe.
At the heart of ESI Motion’s contribution to these vital defense programs is its proven suite of space-rated, flight-heritage hardware. Specifically, the SADE units supplied to Lockheed Martin incorporate the company’s flagship SuperNova and Pulsar motor controllers. These high-performance motion controllers are meticulously engineered to withstand the harsh thermal and radiation environments of space while delivering precise, dependable mechanical control. In satellite operations, solar array drive electronics are essential for orienting power-generating solar panels toward the sun as the spacecraft orbits the Earth, ensuring a continuous and stable supply of electrical power for onboard payloads, communications equipment, and propulsion systems. These motion controllers are specifically designed and rigorously tested to ensure that all operational mission parameters are fulfilled flawlessly, relying on decades of high-reliability technology heritage.
Headquartered in the United States, ESI Motion Inc. has established itself over the past two decades as a trusted industry supplier and strategic partner. The company has a long-standing track record of supporting critical mission operations for defense, aerospace, and industrial customers around the globe. By combining ruggedized engineering with deep technical expertise in motion control, ESI Motion continues to enable complex space missions that demand absolute reliability under extreme operational conditions.
