The U.S. Space Force is partnering with SpaceX to develop MILNET, a new government-owned, contractor-operated satellite communications constellation in low Earth orbit (LEO), according to Delta 8 Commander Col. Jeff Weisler.
The constellation will support the military’s emerging “hybrid mesh network” integrating commercial and Defense Department satellites.
MILNET, now transitioning into Space Force operations via Space Systems Command (SSC) and Delta 8, will consist of over 480 satellites operated by SpaceX. A Delta 8 mission director will oversee operations to align with wartime tempo. The satellites will use SpaceX’s Starshield terminals—featuring enhanced encryption and interoperability with the commercial Starlink network.
Delta 8, based at Schriever Space Force Base in Colorado, manages satellite communications for senior U.S. leadership and global military forces.
Government and industry sources said the secrecy around MILNET is due in part to the National Reconnaissance Office (NRO), which is quietly managing the contract through its classified deal with SpaceX for a separate LEO intelligence satellite constellation.
An SSC spokesperson confirmed that MILNET satellites will carry ESTs, and future Space Force satellites may integrate EST-compatible terminals to enhance secure data transport across the MILNET mesh. Further contract details remain undisclosed.
