Amazon said on October 13, 2026, that the U.S. Army’s DEVCOM C5ISR Center had recently hosted a live Amazon Leo demonstration at Aberdeen Proving Ground in Maryland. The announcement described a Leo Pro antenna connecting as satellites passed overhead and a laptop sent and received data (Amazon’s announcement, relayed by MarketScreener). The announcement date is not the date of the demonstration.
What the Army demonstration involved
Amazon Leo is a satellite network in low Earth orbit, where satellites circle Earth at relatively low altitudes. Amazon identified the terminal used in the demonstration as Leo Pro, a phased-array customer antenna. Aviation Week’s Vivienne Machi reported that the laptop exchanged data while the satellites passed overhead.
For separate background on the network’s build-out, NeoTeo previously covered Amazon Leo’s satellite-manufacturing plans.
What Amazon’s two speed figures describe
Amazon described Leo Pro as delivering speeds of up to 400 Mbps and separately reported a peak download speed above 400 Mbps during the Army demonstration. The first figure describes the antenna; the second is a reported peak from this particular event. Amazon’s announcement gives no test conditions to reconcile the two statements (MarketScreener’s report of the announcement).
Tests Amazon and the Army planned
In the October 13 announcement, Amazon said it and the Army planned further tests involving higher-speed connections, mobile scenarios, and integration with existing Army tactical networks. Those are the stated areas for follow-up testing (Aviation Week’s report).
