Boeing and its subsidiary Millennium Space Systems officially announced the full operational availability of the Resolute satellite platform on April 21, 2026. The new mid-class satellite bus is designed to expand the company’s portfolio for missions that require greater capability and flexibility than traditional small satellites. Positioned as a high-performance solution for the 500-kilogram mass class, Resolute is intended to serve as a cornerstone for future proliferated Low Earth Orbit (pLEO) constellations and national security space architectures.
The Resolute platform provides a significant increase in payload capacity and power compared to previous small-satellite iterations. According to technical specifications released by Millennium Space Systems, the bus delivers up to 3 kilowatts of peak power and supports a wide array of mission types, including electro-optical, infrared, and radio frequency sensing. The platform is engineered for a design life of five to seven years in orbit, offering a balance between the rapid refresh cycles of small satellites and the longevity of larger, more expensive spacecraft.
Jason Kim, Chief Executive Officer of Millennium Space Systems, stated that the Resolute platform was developed to meet the urgent needs of government and commercial customers for resilient and scalable space assets. Kim highlighted that the platform’s standardized architecture allows for a delivery timeline of less than 24 months from contract to launch. This speed is achieved through the use of common interfaces and a pre-qualified supply chain, which reduces the need for non-recurring engineering on a per-mission basis. The company confirmed that production is currently underway at its specialized facilities in El Segundo, California.
The introduction of Resolute comes as the aerospace industry shifts toward more distributed and redundant orbital networks. Boeing’s Space and Launch division noted that the platform is specifically optimized for the requirements of the Space Development Agency’s multi-tranche satellite programs. By utilizing a mid-class bus, operators can host more sophisticated sensors and larger apertures than are possible on standard CubeSats, while still benefiting from the cost efficiencies of high-rate production.
In addition to its physical capabilities, the Resolute platform features advanced cybersecurity protocols and high-maneuverability propulsion systems. These features are designed to ensure mission continuity in increasingly contested orbital environments. While Boeing did not disclose the specific contract values associated with the first Resolute units, the company confirmed that the platform has already been selected for several upcoming technology demonstration missions. The announcement marks a strategic effort by Boeing to capture a larger share of the growing market for mid-sized, high-cadence satellite deployments.
