- Amazon Leo is designed to serve large government customers in places without reliable connectivity
- The Army’s DEVCOM C5ISR Center hosted the demonstration in Maryland
- Peak download speeds topped 400 Mbps as newly deployed satellites passed overhead
Amazon Leo demonstrated satellite-based internet connectivity for U.S. Army personnel during a test at Aberdeen Proving Ground in Maryland. The Army’s Combat Capabilities Development Command C5ISR Center hosted the demonstration, Amazon said Tuesday.
“Amazon has a long track record providing critical cloud and connectivity services to the U.S. Army, and this demonstration at Aberdeen Proving Ground is an important step toward an expanded partnership,” said Liz Martin, head of government for Amazon Leo.
What Is Amazon Leo?
Amazon Leo is Amazon’s low Earth orbit satellite network intended to bring dependable, fast internet service to customers and communities worldwide. Among its target users are large government customers working in locations where connectivity is unreliable. The company is also pursuing public sector connectivity through an agreement with AT&T Business to integrate satellite broadband with fiber and 5G networks.
The network relies on a constellation of thousands of satellites linked to one another through high-speed optical connections. Those satellites communicate with ground infrastructure made up of a secure global network of gateway stations, fiber and internet connection points. Amazon is also expanding its satellite communications portfolio through a planned acquisition of Globalstar, which is intended to add direct-to-device capabilities separate from Leo’s broadband service.
What Did the Amazon Leo Demonstration Show?
Leo Pro, Amazon Leo’s primary customer antenna, linked to the network and supplied broadband connectivity during the demonstration, drawing on both the satellite constellation and ground-based infrastructure worldwide.
A laptop connected through the Amazon Leo Pro exchanged data with recently deployed Leo satellites as they passed overhead. The company said the phased-array antenna is rated for a maximum speed of 400 Mbps and exceeded that rate during the test.
The next phase of testing is expected to examine connectivity in mobile settings, faster data links and compatibility with the Army’s tactical networks. Amazon said it has manufactured more than 1,000 Leo satellites, nearly 400 of which are in low Earth orbit.
The demonstration follows Amazon’s earlier efforts to bring satellite communications to military and government customers. In 2025, L3Harris Technologies and Kuiper Government Solutions partnered to integrate satellite connectivity with tactical communications networks. The partnership focused on delivering SATCOM services to governments and militaries.
