During the annual Space Symposium in Colorado Springs, Boeing and its subsidiary, Millennium Space Systems, announced the launch of Resolute, a new mid-class satellite platform engineered to redefine the balance between high-performance capabilities and rapid deployment. This strategic introduction aims to fill a critical gap in the aerospace market—a segment often referred to as the "donut hole"—which sits between the lightweight requirements of traditional small satellites and the massive power needs of large-scale orbital assets. By combining the agility of a specialized small-satellite manufacturer with the industrial scale of a global aerospace leader, Boeing and Millennium Space Systems are positioning Resolute as a versatile solution for a new era of space architecture.
Addressing the "Donut Hole" in Satellite Architecture
The Resolute platform is specifically designed to operate within the 2-kilowatt (kW) to 4-kW power range. Historically, the satellite industry has been bifurcated into two distinct categories. On one end, Millennium Space Systems has traditionally dominated the small-satellite market with products ranging from 50 watts to 1 kW, focusing on rapid prototyping and low-earth orbit (LEO) missions. On the other end, Boeing’s heritage product lines have catered to high-power requirements, typically starting at 4 kW and scaling up to 30 kW or more for massive geostationary (GEO) communications and defense platforms.
Tony Gingiss, CEO of Millennium Space Systems, highlighted that Resolute was born from a realization that a significant portion of modern mission requirements—both commercial and military—was falling into the unaddressed space between these two extremes. By leveraging the existing technology stacks of both companies, the engineering teams were able to conceptualize a bus that requires no new fundamental product development for its avionics or power subsystems. Instead, Resolute utilizes the flight-proven computers, power products, and avionics that Millennium has already standardized across its smaller fleets.
Technical Synergy and Design Philosophy
The development of Resolute represents a deep integration of Boeing’s payload expertise and Millennium’s "speed-to-orbit" philosophy. The platform is designed to be "bid-ready" immediately, having already progressed to the level of preliminary design review (PDR). This status allows the joint team to respond to government and commercial requests for proposals (RFPs) with a high degree of technical certainty and a reduced timeline for manufacturing.
One of the most significant advantages of the Resolute platform is its versatility across different orbital regimes. While traditional small satellites are often restricted to LEO due to power and radiation constraints, Resolute’s 2-4 kW range makes it a viable candidate for Medium Earth Orbit (MEO) and Geostationary Earth Orbit (GEO) missions. This includes specialized applications such as "micro-GEO" deployments—where smaller, more targeted satellites are used for dedicated regional communications or sovereign defense needs rather than broad, multi-continental coverage.
Strategic Alignment with Space Maneuver Warfare
The unveiling of Resolute coincides with a major shift in the United States military’s approach to space operations. Earlier this week, U.S. Space Command emphasized the urgent need for a "space maneuver warfare" strategy. This doctrine moves away from the concept of satellites as static, vulnerable targets and toward a future where orbital assets are highly maneuverable, capable of avoiding threats, and able to change orbits to meet evolving mission requirements.
Gingiss addressed this shift directly, noting that Resolute is inherently designed for high-agility missions. While a standard communications mission may not require significant maneuverability, the Resolute bus can be outfitted with high Delta-V propulsion systems and agile attitude control systems derived from Millennium’s heritage products. This capability is critical for missions involving Space Domain Awareness (SDA) and "dynamic space operations," where the ability to reposition an asset can be the difference between mission success and asset loss.
Scaling Production: From Prototyping to Industrial Throughput
The announcement of Resolute comes amidst a period of unprecedented growth for Millennium Space Systems. The company reported a record-breaking year in 2025, achieving double-digit satellite deliveries. Looking ahead through 2026, the company has set an ambitious target of delivering 26 satellites, supported by a current backlog of over 100 units.
To meet this demand, Boeing and Millennium have significantly expanded their manufacturing footprint. Kay Sears, Vice President and General Manager of Boeing Space, Intelligence & Weapons Systems, noted that Boeing has strategically allocated physical space and resources to ensure Millennium can scale without the traditional bottlenecks associated with rapid growth. This expansion includes:
- Feeder Factory Growth: Millennium increased its feeder factory—the facility where common components like flight computers and sensors are built—from 15,000 square feet to 22,000 square feet.
- Program-Specific Expansion: The company nearly doubled the floor space dedicated to the "FOO Fighter" program (Fire-control On-orbit Support-to-the-Warfighter), which involves the delivery of eight satellites for the Space Development Agency (SDA).
- Advanced Sensor Production: In February 2026, Boeing inaugurated a new $10 million electro-optical infrared (EO/IR) sensor production line at its El Segundo, California, facility. This line is currently tasked with supporting the construction of 12 Epoch missile warning and tracking (MWT) satellites for the U.S. Space Force.
Sears emphasized that the scaling effort is not just about physical space but about "agile tooling" and modernized production techniques. By implementing automation and repeatable processes, the company aims to move away from the "boutique" hand-crafted nature of traditional satellite manufacturing toward a more standardized, scalable industrial model.
The Hybrid Model: Heritage Meets Agility
The partnership between Boeing and Millennium Space Systems serves as a case study for the broader aerospace industry’s evolution. For decades, the "Prime" contractors (large, established firms like Boeing, Lockheed Martin, and Northrop Grumman) were seen as reliable but slow, while "New Space" startups were seen as fast but risky.
The Resolute platform is an attempt to collapse that dichotomy. Sears characterized the relationship as having a "startup mentality with the resources and heritage of a prime." This hybrid model allows the team to utilize Boeing’s deep experience in complex payloads and government mission assurance while maintaining the rapid iteration cycles that Millennium is known for. For customers, this means they no longer have to choose between a proven, reliable bus and a fast-tracked delivery schedule.
Broader Implications for the Global Space Market
The introduction of Resolute is likely to have ripple effects across both the defense and commercial sectors. In the defense sector, the U.S. Space Force and the Space Development Agency are increasingly looking for "proliferated" architectures—constellations consisting of many smaller satellites rather than a few large ones. Resolute fits perfectly into this "Proximity and Resilience" strategy, providing enough power for sophisticated sensors and jam-resistant communications while being small enough to be launched in batches.
On the commercial side, the platform addresses the growing demand for sovereign communications. Many nations are seeking to establish their own independent space capabilities but do not require the massive, multi-billion-dollar geostationary satellites that have historically dominated the market. A 2-4 kW Resolute bus provides a cost-effective entry point for regional telecommunications, environmental monitoring, and national security missions.
Furthermore, the "bid-ready" nature of the platform suggests that Boeing and Millennium are looking to capture a larger share of the rapid-response space market. As geopolitical tensions rise, the ability to replace a lost capability or deploy a new sensor in a matter of months rather than years has become a top priority for global defense departments.
Conclusion and Future Outlook
As the Resolute platform moves from design review to active bidding and production, it marks a significant milestone in Boeing’s broader strategy to modernize its space portfolio. By filling the "donut hole" and focusing on modularity and maneuverability, Boeing and Millennium Space Systems are not just launching a new product; they are signaling a shift in how they intend to compete in an increasingly crowded and fast-moving orbital environment.
With a massive backlog of 100 satellites and a newly expanded manufacturing infrastructure, the focus now shifts to execution. The industry will be watching closely as the first Resolute units are contracted, looking for evidence that this "Prime-plus-Agile" model can truly deliver the speed and reliability promised at the Space Symposium. In an era where space is increasingly contested and congested, the Resolute platform may provide the necessary flexibility to ensure continued access and utility in the high frontier.
