Boeing and its subsidiary Millennium Space Systems have announced the launch of a new mid-class satellite platform called Resolute. Designed to offer more capability than traditional small satellites while providing greater speed and flexibility than larger satellite programs, Resolute is a 2-4 kilowatt satellite bus applicable to a range of communications, sensing, and other mission needs for both defense and commercial applications.

Why it matters

The Resolute platform is intended to fill a 'donut hole' between Millennium's smaller satellite offerings and Boeing's larger, more complex models. This new mid-class bus leverages common Millennium products to enable faster development and deployment, while still providing enhanced capabilities compared to traditional small satellites. The increased maneuverability and agility of Resolute also make it a potential fit for emerging space maneuver warfare strategies.

The details

Resolute is designed to blend Boeing's core payload technologies with Millennium's speed and bus products. It utilizes common Millennium flight computers, avionics, and power products, allowing the teams to develop the new platform without any new product development. Resolute can be deployed across orbital regimes and is targeted at commercial and military communications applications, including sovereign communications and micro GEO deployments. The platform's high maneuverability and Delta-V also make it adaptable for other mission needs.

  • Resolute is currently at the preliminary design review stage and is 'bid-ready' in 2026.
  • In 2025, Millennium Space Systems posted record satellite deliveries, with plans to deliver 26 satellites in 2026 from a backlog of 100 satellites.

What they’re saying

“When we looked at this 2 to 4 kW range, we thought we could do it without any new products. The combined teams actually came up with a concept, which we call Resolute. It allows us to fill that hole [and] use all the same common products — no new product development from avionics or power subsystems.”

— Tony Gingiss, CEO of Millennium Space Systems

“Outside of the physical space, then it's about available parts. We try to stock our common product parts on the on the shelf. Then it's about the tooling. When we're talking about tooling for Millennium and this new Resolute bus, this is agile tooling. We're looking at modernized ways of doing things — automation, repeatability, things that we can scale.”

— Kay Sears, Vice President and General Manager of Boeing Space, Intelligence & Weapons Systems

What’s next

Resolute is expected to be 'bid-ready' in 2026, as Millennium Space Systems continues to ramp up its satellite production capabilities to meet growing demand.

The takeaway

The new Resolute satellite platform represents a strategic collaboration between Boeing and its subsidiary Millennium Space Systems, combining the aerospace giant's payload expertise with Millennium's agile development approach to deliver a mid-class satellite solution that bridges the gap between small and large satellite systems.
