On Wednesday, April 15, 2026, at the 41st Space Symposium in Colorado Springs, Boeing and its subsidiary Millennium Space Systems officially introduced “Resolute,” a new mid-class satellite platform. The platform is specifically engineered to bridge the gap between high-performance small satellites and traditional large-scale systems, targeting the urgent requirements of both commercial and government customers for greater speed and mission flexibility.
The unveiling occurs as Boeing executes a significant industrial expansion, with the company targeting 26 satellite deliveries in 2026. This production focus is supported by investments in standardized components and repeatable manufacturing processes across the combined Boeing and Millennium portfolios.
Strategic Evolution of the Satellite Portfolio
The Resolute platform is the result of combining Boeing’s deep mission heritage and payload expertise with Millennium’s high-rate manufacturing approach. It is designed for missions that require more capability—such as larger sensor apertures or increased power—than a traditional small satellite can provide, but with shorter development timelines than typical large-scale satellite programs.
The platform leverages flight-proven avionics and common products from Millennium’s existing lines, which have been refined through participation in high-priority national security programs. This heritage includes the Space Systems Command’s efforts to field resilient constellations in various orbital planes.
Technical Specifications and Modular Architecture
Built on a scalable architecture, the Resolute platform is designed to be adapted quickly as mission requirements evolve. Key specifications include:
- Orbit Versatility: Optimized for diverse operational environments, including Low Earth Orbit (LEO) and Medium Earth Orbit (MEO).
- Payload Integration: Features a modular design that allows for the rapid integration of advanced sensors and communication packages.
- Production Readiness: Utilizes repeatable manufacturing approaches to support the high-rate delivery demands of proliferated constellations.
- Enhanced Capability: Provides the structural mass and power generation necessary for sophisticated sensing missions that exceed SmallSat constraints.
Rationale: Meeting the Demand for Scalable Space
The primary driver behind the Resolute platform is the shift in the defense and commercial sectors toward resilient, distributed satellite architectures. By moving away from a reliance on single, complex “battlestar” satellites, customers can deploy larger numbers of mid-class systems to ensure mission continuity in contested environments.
“Resolute is designed for missions that need more capability than a traditional small satellite can provide, with greater speed and flexibility than a typical large satellite program,” Boeing stated during the symposium. This approach allows the company to capture a larger share of the market where defense spending is increasingly focused on attritable, mass-produced systems.
Production Roadmap to 2027
Boeing and Millennium are currently scaling manufacturing output to support a growing backlog of orders. The companies emphasized that the Resolute platform is a central component of their effort to offer more practical options for fielding capability in months rather than years.
With the first units of the Resolute class expected to enter integration later this year, the platform is positioned to be a primary vehicle for upcoming missile tracking and secure communication manifests. Looking toward 2027, the focus will remain on expanding the production of standardized buses to meet the projected needs of the U.S. Space Force and international sovereign partners.
