What Is Starshield, SpaceX's Military Version of Starlink?
Starshield is a SpaceX business unit building military and intelligence satellite systems for the Pentagon. Elon Musk says it is separate from commercial Starlink, yet the two share much of the same satellite network.
Elon Musk, the head of US space company SpaceX, on Wednesday used a post on X to explain the difference between the company's commercial satellite internet service, Starlink, and its military counterpart, Starshield. The question has drawn fresh attention because the two systems often rely on the same underlying satellite technology while being used in different ways.
Musk said Starshield systems are owned and controlled by the US government, and that any limits on speed or usage are set by the US military or the president. Starlink, he said, is owned and controlled by SpaceX, and its use is limited to civilian or defensive activities rather than offensive military action.
Starlink
Starlink is a satellite internet network of more than 11,000 satellites that send broadband directly to user terminals roughly the size of a folded newspaper. It has about 13 million subscribers, from households and hikers to shipping firms and major airlines, and is SpaceX's main source of profit. The company launched its first Starlink satellites in 2019 on reusable rockets.
Starshield
Starshield is a SpaceX unit that develops military and intelligence satellite systems for the Pentagon, the US Department of Defense. Its secure communications use enhanced encryption and dedicated terminals, but run on the large Starlink constellation. SpaceX says the system can also offer Earth observation and the integration of sensors or other payloads.
The Pentagon is the largest Starshield customer and has spent billions of dollars on both Starlink and Starshield. Reuters reported in 2024 that it had also bought dedicated Starshield satellites, including ones for missile-warning missions and a spy constellation for the National Reconnaissance Office.
Blurred boundaries
Questions about the link between the two have lingered since 2022, when Russia threatened Western satellites supporting Ukraine. SpaceX unveiled Starshield later that year. Earlier this year the Pentagon clashed with SpaceX over higher prices for satellite services used by military drones during the Iran conflict: SpaceX argued some customers paying around $5,000 per terminal for Starlink should have used a Starshield service costing about $25,000.
Britain has also adopted Starshield, and New Zealand is running a trial to assess its value for military operations.
