The U.S. Air Force has awarded Xos a prototype Other Transaction Agreement (OTA) to develop and deliver a deployable mobile charging solution for electrified support equipment and vehicles.
The Air Force Global Strike Command Rapid Capabilities Division 2026 Showcase granted the award. It marks Xos’s first U.S. Air Force contract and its entry into the defense market, reflecting “growing cross-sector demand for the Company’s mobile energy storage platform across commercial fleets, ports, municipalities, and now national defense.”
Under the agreement, Xos will adapt its Xos Hub mobile battery energy storage system for defense charging applications. The system will provide high-capacity, standards-based charging for electrified support equipment and vehicles without requiring permanent infrastructure.
“This award marks a strategic inflection point for Xos,” said Dakota Semler, CEO of Xos, in a press release. “When the United States Air Force evaluates the market and selects our technology, it confirms what we set out to build from day one: a mobile energy platform proven in commercial operations that can meet the most demanding mission requirements in the field.”
Grid-independent power
Commercial fleets, ports, municipalities, and now national defense use the Xos Hub mobile battery energy storage system. Under the Air Force agreement, Xos will modify the system for military applications and demanding field environments.
The company designed the Xos Hub to provide high-capacity, grid-independent power without permanent infrastructure. The prototype will undergo primary assembly and integration at Xos’s Byrdstown, Tennessee, facility.
“This award reflects disciplined execution across engineering, operations, and manufacturing,” said Giordano Sordoni, co-founder and chief operating officer of Xos.
“As a non-traditional contractor, we move fast, and we deliver, adapting a commercially proven product for a new mission and building it right here in Tennessee,” Sordoni added. “It is a powerful demonstration of the flexibility of our platform and the strength of our American manufacturing base.”
According to figures cited in the company’s announcement, the global military power solutions market is projected to reach $19.87 billion by 2033, growing at an annual rate of 7.7%.
Xos also cited the U.S. Department of Defense as the largest institutional consumer of energy in the United States. The U.S. Army has committed to fielding microgrids at every installation and establishing an all-electric non-tactical vehicle fleet by 2035.
The Air Force award extends the Xos Hub customer base beyond commercial fleets and municipal operators into the U.S. defense sector. Xos said its pipeline also spans port authorities, utilities, and federal grant programs.
“Defense is a significant new addressable market for the Xos Ecosystem, and it is one where our advantages compound: American design and manufacturing, proven reliability, and deployable power that needs no fixed infrastructure,” Semler said.
Moveable power
The agreement has a period of performance extending into late 2027. During that period, Xos will demonstrate the Xos Hub across new environments while further developing its domestic manufacturing capabilities.
The company said it intends to build on the Air Force award by pursuing additional opportunities to provide its mobile charging and energy storage technology to fleets and operators seeking reliable, deployable power without permanent infrastructure.
“This is how Xos scales, carrying a platform already trusted across multiple sectors into the highest-stakes markets in the world,” Semler concluded in a press release.
