Pentagon Awards Inmarsat Government $307 Million Satellite Contract as Marine Corps Expands Global Communications Network Worldwide

Inmarsat Government Inc. has been awarded a major U.S. defense contract valued at up to $307,102,288 to provide global communications connectivity for the Marine Corps.

The Reston, Virginia-based company will support the Marine Corps Enterprise Commercial Satellite Services contract, giving the service access to commercial satellite communications across multiple orbital systems and frequency bands.

The award is structured as a ceiling firm-fixed-price contract, meaning the total value can reach more than $307 million over the life of the agreement.

Contract Covers Multi-Orbit Commercial Satellite Access

The contract will provide access to multi-orbit commercial satellite communications, using commercially available frequency bands and a mix of space-based and terrestrial resources.

The work also includes day-to-day resource management, allowing the Marine Corps to maintain and coordinate satellite communications support across operational environments.

The services will be performed at various locations worldwide, reflecting the global nature of Marine Corps missions and communications needs.

The contract is expected to run through March 16, 2031.

Competitive Award Received One Offer

The contract was awarded through a competitive acquisition process, although only one offer was received.

At the time of award, $3,257,694 in fiscal 2026 operations and maintenance funds was obligated.

The contracting activity is the Space Systems Command Commercial Space Office in Chantilly, Virginia, under contract number FA254126DB001.

Odyssey Systems Receives $48.9 Million Space Domain Awareness Contract Modification

In a separate award, Odyssey Systems Consulting Group Ltd. of Colorado Springs, Colorado, received a $48,915,737 contract modification for Space Domain Awareness support.

The modification applies to a previously awarded contract and covers Option Year Four for technical acquisition and advisory services.

The new award raises the total cumulative face value of the contract from $153,116,457 to $202,032,194.

Space Domain Awareness Work Continues in Colorado Springs

Odyssey Systems will perform the work in Colorado Springs, Colorado, with completion expected by May 9, 2027.

Funding obligated at the time of award includes $14,742,220 in fiscal 2026 operations and maintenance funds, $489,365 in fiscal 2026 procurement funds, and $8,470,466 in fiscal 2026 research, development, test and evaluation funds.

ARCTOS Awarded $9 Million for High-Speed Vehicle Structures Research

A third contract was awarded to ARCTOS Technology Solutions LLC of Beavercreek, Ohio.

The company received a $9,000,000 cost-plus-fixed-fee contract to develop future aerothermoelastic structures technologies.

The research is intended to improve capabilities related to response prediction, life prediction and testing for high-speed airbreathing vehicles operating in high-temperature environments.

Research Work Split Between Beavercreek and Wright-Patterson

ARCTOS will perform the work in Beavercreek, Ohio, and at Wright-Patterson Air Force Base, also in Ohio.

The project is expected to be completed by June 30, 2031.

The award followed a competitive acquisition process that received two offers.

At the time of award, $144,230 in fiscal 2026 research, development, test and evaluation funds was obligated.

The contracting activity is the Air Force Research Laboratory at Wright-Patterson Air Force Base, under contract number FA2391-26-C-B019.

Impact and Consequences

The Inmarsat Government award highlights the Pentagon’s growing reliance on commercial satellite communications to support global military operations.

For the Marine Corps, access to multi-orbit satellite services could improve communications flexibility, resilience and coverage across deployed forces.

The Odyssey Systems modification reinforces the Space Force’s continued investment in Space Domain Awareness, a critical mission area focused on monitoring and understanding activity in orbit.

The ARCTOS contract points to long-term research priorities around high-speed airbreathing vehicles, especially systems that must survive extreme heat and structural stress.

Together, the awards show continuing U.S. defense investment in space communications, orbital awareness and advanced aerospace technologies.

What’s next?

Inmarsat Government will begin supporting worldwide Marine Corps satellite communications services under the contract, with work continuing through 2031.

Odyssey Systems will continue Space Domain Awareness advisory and acquisition support through May 2027.

ARCTOS will move forward with research and development on aerothermoelastic structures technologies, with work expected to run through June 2031.

Further funding obligations may follow as each contract progresses through its performance period.
