Amazon has unveiled Leo Ultra, a high-throughput phased-array terminal for its upcoming satellite internet service, now rebranded from Project Kuiper to Amazon Leo. The device is part of an enterprise-grade hardware lineup that will support initial customer deployments beginning in 2025, with broader availability scheduled for 2026.
The Ultra terminal is Amazon’s largest and fastest offering to date, designed for permanent installation at fixed sites. It measures roughly 20 by 30 inches with a chassis depth of 1.9 inches and is intended for pole-mounted outdoor use. Internally, the device incorporates Amazon silicon and a full-duplex phased-array system capable of simultaneous uplink and downlink, supporting download speeds of up to 1 Gbps and upload speeds of up to 400 Mbps.

Leo Ultra was one of three customer terminals shown as part of the new network push. Alongside it, Amazon previewed a mid-sized Leo Pro terminal designed for portable or vehicle-mounted use, and a compact 7-inch square Leo Nano unit rated for up to 100 Mbps. All three run on custom silicon developed by Amazon’s device teams and share the same core waveform and protocol stack.
The new hardware arrives as Amazon begins rolling out its constellation. As of November 2025, the company has launched more than 150 low-Earth orbit satellites under Project Kuiper, with multiple mass deployment launches completed since April. The company plans to launch several thousand satellites in total to meet its global coverage targets, and CEO Jeff Bezos has stated ambitions to begin deploying space-based data centers in the next 10 to 20 years.
Amazon is positioning the network as a hybrid connectivity layer that ties directly into AWS infrastructure. The Leo architecture includes support for “Direct to AWS” (D2A) links that route satellite traffic straight into cloud workloads without passing through the public internet. The company has not yet disclosed pricing details for the Leo terminals and service plans, but it is thought that the company intends to begin commercial service with select enterprise partners, followed by general availability next year.
Amazon’s entry into the satellite internet market arrives as rivals, including SpaceX’s Starlink, continue to expand their own constellations and service offerings. With gigabit-class performance and integrated cloud hooks, Leo Ultra represents Amazon’s first full hardware and network package aimed at the high-end segment of the market.
