Should the U.S. military rely on private-sector companies for essential defense communications infrastructure?
Boeing is currently outfitting the Air Force fleet of C-17 Globemaster cargo jets with Starshield satellite communications technology at its facility in Port San Antonio. The company has completed installations on nine aircraft as part of a multi-year effort to integrate the systems across the fleet.
Why it matters
This initiative provides C-17 jets with a persistent satellite link, enabling the sharing of mission-critical data in flight. The rollout represents an expanding military reliance on the Starshield network for secure, high-bandwidth connectivity.
Boeing is integrating the Airlift/Tanker Open Mission Systems (ATOMS) into the C-17 fleet to leverage the Starshield satellite network. The Air Force has committed to equipping 19 jets by March 2027 out of a total planned fleet of 222 aircraft.
The players
Boeing
An aerospace and defense manufacturer currently managing the C-17 fleet maintenance and equipment integration.
Sierra Nevada Corp.
A systems integrator and defense contractor that supplies the Starshield and ATOMS equipment kits.
SpaceX
The private space company that operates the Starshield satellite network and its associated connectivity services.
The details
The integration involves installing hardware kits designed to link the aircraft to the Starshield satellite constellation. ATOMS serves as an open architecture framework that allows the jets to transmit and receive operational data via these satellites. Sierra Nevada Corp. manufactures the required kits, which are now being fitted to the cargo planes at the Port San Antonio site.
Timeline
March 2027: The installation of Starshield equipment on 19 C-17 jets is scheduled to conclude.
Q3 2026: SpaceX reported $4.4 billion in profit and $2.37 billion in connectivity revenue.
The Tech Race
The project follows the architectural standards set by the ATOMS program to ensure satellite connectivity for heavy transport aircraft. This shift moves the C-17 fleet toward the satellite-integrated communications models increasingly standard in modern tactical and transport aviation.
The facility at Port San Antonio remains the hub for this integration work, which will affect the fleet's operational capabilities through early 2027. San Antonio residents and industry observers can monitor the progress of these 19 jets as they return to service with new satellite links.
The takeaway
The Air Force is prioritizing secure, high-speed satellite connectivity for its transport fleet via the Starshield network. Observers should track the March 2027 milestone to see if the project expands beyond the initial 19-jet contract toward the full 222-aircraft goal.
