Stephenson Stellar Corporation

Stephenson Stellar Corporation, a nonprofit defense and space manufacturing specialist based in Shreveport, Louisiana, operates as a prime contractor on space systems engineering, space cyber range development, and advanced defense technology research and development, with secondary engagement as a subcontractor on Department of Defense space security research programs. The vendor competes full-and-open without set-aside designation across its prime footprint, drawing on specialized expertise in satellite systems, space cybersecurity, and emerging technologies including artificial intelligence and machine learning applied to multi-domain defense.

Stephenson Stellar's recent prime work anchors to the Department of the Air Force and the Missile Defense Agency. The top funding agency by dollar value is the Department of the Air Force, which accounts for $62.4 million in a definitive cost-plus-fixed-fee contract awarded June 12, 2023, for Systems, Technologies, and Emerging Capabilities (STEC) support spanning space systems engineering and technology demonstration through June 11, 2028. The Department of the Air Force Air Combat Command contributes $19.7 million in potential value; the Air Force Materiel Command Research Laboratory leads by award count with nine awards totaling $22.7 million across space cyber range foundation workshops, wireless testing capabilities, and systems support. The Missile Defense Agency awarded a multi-billion-dollar Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) Multiple Award Indefinite Delivery Indefinite Quantity contract on December 29, 2025, providing a platform for task orders spanning research and development, prototyping, systems engineering, weapon design, production, test and evaluation, and cybersecurity modernization in air, missile, space, cyber, and hybrid threat domains through December 28, 2035; the initial task order carries a nominal $500 ceiling. Stephenson Stellar also holds a $6.5 million GSA Federal Supply Schedule contract (awarded October 2, 2023, through October 1, 2028) under Special Item Numbers 541715 (engineering research and development) and OLM (order level materials), with Air Force Materiel Command exercising a $62 thousand delivery order for a hands-on space cyber range foundation workshop completed May 7, 2025.

GSA Schedule labor spans ten categories from $101.15 to $334.34 per hour, all requiring a bachelor's degree with no security clearance mandated. Entry-level Assistant Space & Cyber Systems Engineers start at $101.15 per hour with two years' experience, while Principal-level Space & Cyber Software Engineers and Space & Cyber Principal Technical Directors command $334.34 per hour with fifteen years of experience; mid-spectrum roles such as Technical Writer and Business Analyst price at $202.28 per hour with ten years' experience.

A significant recompete cliff surfaces in the next twenty-four months: two awards with combined potential value of $72 million face ultimate completion dates within that window, representing the $62.4 million STEC definitive contract (June 11, 2028) and the $9.6 million Stellar Applied Digital Space Range (SADSR) Other Transaction Agreement (July 7, 2028). Activity shows concentration in space and emerging technology domains; the top NAICS category is Research and Development in the Physical, Engineering, and Life Sciences (fifteen awards). Stephenson Stellar subcontracts to Radiance Technologies Inc. on Department of Defense space security research including Neuro-Symbolic Perception, Action, and Reasoning (NEUROSPAR) and Distributed, Automated, and Intelligent Hardware and Software Security (DAIHSS) programs, delivering scientific and engineering expertise in space asset resilience and defensive cyber operations support under awards dated August 20, 2021. Overall, Stephenson Stellar has executed 16 awards (50% prime, 50% sub) totaling $121 million in combined potential value, with $70.3 million obligated as of the source snapshot date.
