Stell Engineering Secures $5.8M Space RCO Contract for Advanced Systems Integration Software
Stell Engineering has been awarded a $5.8 million Space RCO contract to deploy enhanced systems integration software that will accelerate the development and deployment of complex space systems for national security missions.

Stell Engineering, Inc. has been awarded a $5.8 million SBIR Phase III contract with the Space Rapid Capabilities Office to enhance and deploy the company's advanced systems integration software. The 24-month contract will fund Space RCO-tailored enhancements to Stell's core software platform and establish a multi-layered secure deployment infrastructure.
The contract represents a significant advancement in systems engineering capabilities for space missions, focusing on improving requirements management and accelerating the integration of complex system-of-systems involving hardware, software, and firmware interfaces. This partnership will enable Space RCO to maintain rapid delivery schedules for evolving space missions while enhancing cybersecurity measures at the Controlled Unclassified Information level, including one-way connections into high-side environments.
This Phase III award builds upon Stell's previous success with an AFWERX Direct to Phase II Small Business Innovation Research contract awarded in February 2024, which served Space Systems Command's Assured Access to Space and Space Systems Integration Office programs. The company has collaborated with multiple defense organizations including Space Systems Command, AFWERX, SpaceWERX, COMSO, and supporting SETA contractors at ManTech and Alpha Omega Group to advance the Phase II innovation effort.
Stell's mission focuses on ensuring United States capability dominance through accelerated engineering of complex systems. The company's software platform is designed to help engineers within the Department of Defense and supporting contractors manage mission requirements, interfaces, testing, and compliance workflows more efficiently. This capability becomes increasingly critical as space emerges as a contested frontier requiring rapid deployment of advanced technologies.
The contract will enable Stell to place its engineering team directly alongside Space RCO personnel, facilitating close collaboration on fielding novel hardware technologies for space applications. This partnership approach aims to drive technical execution speed that outpaces potential adversaries in developing and deploying advanced space systems.
Stell's systems engineering platform is already being utilized by various defense and commercial entities, including satellite companies, ship builders, and battery manufacturers, to ensure products meet customer, interface, regulatory, and functional requirements. Defense organizations such as Space Systems Command currently use Stell to develop and maintain interface specifications for faster procurement and integration of new launch vehicles, spacecraft, and payloads.
