Commercial Satellite Manufacturing Scales Up as LEO Demand Drives New Production Lines

June 1, 2026

Space vehicle and satellite development programs are driving demand for new small- and medium-sized satellites across commercial and defense imaging, data collection, and other space-based applications.

Production-Line Expansions and Backlog-Driven Builds

Recent announcements from two of the world’s largest aerospace companies — Airbus and Boeing —highlight rising demand for new satellites and space vehicles. In January, Airbus Defence and Space was awarded a contract by Eutelsat to build 340 OneWeb LEO satellites. Airbus is manufacturing the satellites on a newly installed production line at its Toulouse facility, with deliveries set to begin toward the end of 2026.

“This latest contract from Eutelsat is an endorsement of our design and manufacturing expertise for LEO satellites. Airbus has been a key partner and supplier to Eutelsat for more than 30 years and this award further cements our important relationship,” said Alain Fauré, Head of Space Systems in Airbus, commenting on the latest contract award.

Eutelsat’s goal with the OneWeb constellation is to provide high-speed internet services globally, with plans for more than 600 satellites in 12 synchronized orbits.

A month after the Airbus announcement, Boeing opened a new production line at its El Segundo, California, satellite manufacturing facility. The expanded footprint is now 9,000 square feet (nearly 840 square meters). The line’s initial project is producing electro-optical infrared (EO/IR) sensors for 12 U.S. Space Force Resilient Missile Warning and Tracking (MWT) MEO program vehicles to be launched in 2027.

In 2025, Boeing recorded its highest-ever satellite output within its Space Mission Systems division and expects output to increase again this year.

“Last year, we proved we can deliver at pace, and we’re not taking our foot off the gas,” said Sam Greaves, VP Space Mission Systems Growth & Engagement, Boeing. “We’re moving to more than double our satellite output this year, and investments like this, along with other factory upgrades and continued investment in our team, are how we do it with schedule credibility.”

At the 2026 Space Symposium, Boeing subsidiary Millennium Space Systems announced plans to design and manufacture a new mid-class satellite bus for multi-orbit defense and commercial missions. The new satellite platform, “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 plans to deliver 26 satellites this year, with a focus on repeatable manufacturing. Boeing describes Resolute as fitting into the “middle ground” between smaller, less capable satellites and larger, more complex programs that are expensive to machine and can take several years to build.

“This is about more than one product,” said Tony Gingiss, CEO of Millennium Space Systems. “We are building the production depth, common architecture and capacity to scale with demand. That includes expanding into mission areas where customers want more capability, while staying focused on execution and delivery across the backlog already in front of us.”

Constellations Broaden Beyond Communications and Imaging

Beyond high-volume communications constellations, manufacturers are also building production capability for specialized architectures — ranging from missile-warning sensors to LEO navigation services — each with distinct integration and lifecycle requirements.

Xona Space Systems, a startup developing LEO satellites for a next-generation global navigation service, opened a satellite manufacturing facility in April. At the Burlingame, California facility, Xona is building its Pulsar satellites, with the goal of producing 258 spacecraft for a LEO GNSS constellation featuring its patented “distributed clock architecture.”

“Pulsar expands on today’s trusted navigation infrastructure by combining multiple sources of time into a single, highly precise system. By comparing and validating time across the constellation, Pulsar achieves clock measurements beyond what any single source can provide,” the company’s website notes.

The satellites have software-defined payloads and flight systems allowing new signal architectures and performance improvements to be continuously uploaded in-orbit. Xona notes that the operating life of the Pulsar satellites is five years.

Xona’s website also provides a brief overview of the facility’s manufacturing process, which starts with subsystem manufacturing.

“Satellite components from electrical harnesses, avionics, propulsion, and payload are assembled using modular subassemblies, enabling consistency across production builds. Subassemblies and solar panels are integrated directly into the spacecraft chassis, bringing guidance, navigation, control, and structural systems together with precision. The result is a complete system optimized for maneuverability, stability, and performance in orbit,” the website notes.

The facility will serve as Xona’s integration and assembly line, with plans to build a “resilient, secure supply chain.”

“What used to take billions of dollars and decades to build, we’re now doing in years. The entire Pulsar constellation will be built right here, inside this decade, for the cost of one GPS satellite on orbit today,” said Brian Manning, CEO of Xona. “Here, we’re not just proving Pulsar’s capability can exist, but that we also have the means and resources to build it at scale.”

Engineering Focus: Architectures, Modularity, and Scalable Subsystems

As production scales, developers are refining satellite architectures and subsystem strategies to balance capability, schedule, and cost — often leaning on modular designs, software-defined payloads, and supply-chain partners.

Unified spatial intelligence company Vantor introduced two new satellite systems in April: Vantor Vantage, next-generation 20 cm-class imaging satellites, and Vantor Pulse, a fleet of 40 cm-class satellites designed for persistent, high-frequency monitoring. The new satellites build on the fundamental design of its WorldView Legion satellites in the 700 kg class.

“There are no commercial 20 cm-class imaging satellites operating today, which is part of what makes this system so novel,” Vantor Chief Space Systems Officer Matt Jenkins told Aerospace & Defense Technology, referring to the new Vantage satellite.

“Vantage is designed for 20 cm-class imaging, while Vantor Pulse is designed as a 40 cm-class high-revisit fleet,” Jenkins said. “When combined with our existing fleet on orbit, the system is intended to eliminate the traditional tradeoff between image detail and revisit speed. The expanded fleet is expected to improve revisit rates five-fold and enable imaging of the same location as frequently as every 15 minutes.”

Jenkins said Vantage and Pulse are being developed in close alignment with government and commercial customers who require faster, more current, and more actionable spatial intelligence. He said those customers are primarily focused on two emerging needs.

First, customers are demanding significantly higher temporal revisit to monitor change — whether for tactical operations, maritime awareness, infra-structure monitoring, or dynamic site activity. Pulse is designed to meet this need by enabling a more proliferated, responsive constellation without sacrificing data quality. Second, even with increased revisit, customers still require the highest levels of detail and analytical fidelity.

“That is where Vantage plays a critical role, delivering exquisite, high-resolution imagery for deeper insight,” Jenkins said. “Together, the systems are complementary: Pulse provides the frequency to detect change, while Vantage delivers the precision to fully understand it.”

As a unified spatial intelligence company, Vantor does not manufacture its satellites. Instead, the company architects mission requirements, oversees design, implements programs and operates the satellites once in orbit.

Vantor relies on manufacturing partners, and Jenkins said the company’s primary investments are in systems engineering, software, and proprietary technology that enhances performance across the full Earth-observation lifecycle, from collection to delivery.

“This includes advancements in onboard processing capabilities to make data collection more efficient and optimize downlink, as well as continued development of our AI-driven processing pipeline built on our extensive geospatial data archive,” Jenkins said. “In parallel, we have invested in modularizing our satellite and ground system architectures. This approach allows us to more rapidly integrate new capabilities, scale the constellation, and streamline the deployment of both Vantage and Pulse. The result is a more flexible and efficient system that accelerates innovation without compromising performance.”

Demand is also pushing into the satellite supply chain, with component manufacturers expanding operations for growing LEO programs. In April, Voyager Technologies said it had doubled production capacity of satellite propulsion systems at its Denver, Colorado-area facility compared with a year ago.

At the Denver facility, Voyager produces propulsion modules that integrate the propellant tank, thruster, electronics controller, and propulsion distribution system into a single, compact unit. The capacity increase was driven by the installation of new equipment and improved production flow.

“We added additional testing chambers and clean room space, but the bigger impact came from reorganizing how we build. We introduced parallel production cells, improved digital work instructions, and reduced bottlenecks across the line. The focus was on building a production system that can scale reliably, not just adding more machines,” a representative for Voyager Technologies said in an emailed statement.

“Voyager is seeing growing demand for propulsion systems driven by the expansion of commercial space operations. Customers are seeking propulsion solutions that support maneuverability, mission flexibility, and long-term performance. While satellites remain a primary application, the broader market is evolving toward more dynamic and complex mission profiles. Voyager is focused on supporting this growth with scalable propulsion solutions that meet the needs of both commercial and national security customers, including future missions aligned with efforts such as Artemis II.”
