What Is Amazon Leo? The history of Project Kuiper
Amazon Leo is Amazon’s satellite broadband network, developed as Project Kuiper. Here is how it works and how it progressed from early designs to prototype tests, production launches and a new name.
Broadband through a network in space
Leo is designed to bring internet access to homes, businesses and communities where terrestrial connections are limited. Instead of depending on a cable reaching the property, a customer antenna communicates with satellites passing overhead.
Ground gateways connect the space network to the wider internet. Optical links between satellites provide additional routes for data before it returns to Earth.

Three terminals for different demands
| Terminal | Download, up to | Design and positioning |
|---|---|---|
| Leo Nano | 100Mbps | Compact, portable design, approximately 18cm square. |
| Leo Pro | 400Mbps | A larger antenna, approximately 28cm square. |
| Leo Ultra | 1Gbps | Enterprise-grade equipment; uploads advertised at up to 400Mbps. |
Amazon’s advertised equipment capabilities, rather than measured customer averages or guaranteed package speeds. Pro dimensions are rounded from 11 inches; 1Gbps equals 1,000Mbps.
Actual performance depends on the service plan, local capacity, weather conditions and the network inside the property. For video calls and gaming, latency and consistency matter alongside headline download speed.
The story, year by year
The project developed through overlapping stages: permission to operate, proof that the technology worked, factories to build it and launches to put it into service.
- 2018Early work
An idea takes shape
Amazon’s later account places the project’s beginnings around 2018. In its November 2025 rebrand announcement, the company said the work had started seven years earlier with a small engineering team and initial designs.
The team used Project Kuiper as a code name, inspired by the Kuiper Belt in the outer Solar System. The task was to create a complete communications system, bringing together satellites, customer antennas, software and a ground network.
- 2019Public proposal
Project Kuiper becomes public
The programme became public in spring 2019. Amazon proposed a large satellite constellation to extend broadband beyond the reach of existing networks. Its subsequent approval announcement refers back to that spring unveiling.
This was still a proposed network. Design work and regulatory applications came before hardware in orbit, which explains the gap between the first public accounts and the first launches.
- 2020US approval
The FCC approves the original constellation
On 30 July 2020, the US Federal Communications Commission approved the original 3,236-satellite system by a 5-0 vote. Amazon announced an investment exceeding $10 billion, covering development, manufacturing, ground infrastructure and customer equipment.
The approval established the regulatory basis for US operations. Later FCC records describe a modified first-generation constellation of 3,232 satellites; the two figures refer to different versions of the authorised design.
- 2021Rockets and tests
The launch plan and prototypes emerge
On 19 April, Amazon announced an agreement for nine ULA Atlas V launches. On 1 November, it presented plans for KuiperSat-1 and KuiperSat-2, two prototypes intended to test communications, customer terminals and flight operations in space.
The original prototype plan targeted ABL Space Systems’ RS1 rocket in 2022. That timetable and launch arrangement changed before the eventual October 2023 mission.
- 2022Launch capacity
Amazon secures a much larger rocket programme
On 5 April, Amazon announced agreements covering up to 83 launches with Arianespace, Blue Origin and ULA. They included Ariane 6, New Glenn and Vulcan Centaur, alongside the existing Atlas V arrangement.
The maximum included options, and represented future launch capacity. Using several providers was intended to reduce dependence on any one rocket as Amazon worked towards deploying thousands of spacecraft.
- 2023First flight
Antennas, prototypes and a working laser link
In March, Amazon revealed three customer terminal engineering designs, establishing the compact, standard and high-bandwidth approach behind today’s equipment. Its standard terminal had a target manufacturing cost below $400, a production figure rather than a confirmed Amazon Leo equipment price.
On 6 October, KuiperSat-1 and KuiperSat-2 launched aboard a ULA Atlas V from Cape Canaveral. The Protoflight mission tested the end-to-end communications system, including the route through ground networking, satellites and a customer antenna.
In December, Amazon reported 100Gbps optical links between the prototypes across roughly 1,000 kilometres during test windows. The result supported its planned mesh network in space. It was an inter-satellite link speed, separate from household broadband performance.
Amazon also announced three Falcon 9 launch contracts on 1 December, adding SpaceX to its suppliers even as Kuiper prepared to compete with Starlink.
- 2024Manufacturing
The project moves towards repeatable production
Amazon’s Kirkland, Washington satellite factory opened in April. A June production update described the manufacturing and testing infrastructure needed to build a much larger fleet.
In May, Amazon announced the controlled deorbit campaign for the prototypes. After testing the technology, the team could study the spacecraft’s retirement process while work shifted towards production hardware. The schedule had moved: production launches earlier targeted for 2024 began the following year.
- 2025Deployment
Production satellites reach orbit, then Kuiper becomes Leo
On 28 April, mission KA-01 launched the first 27 production satellites on an Atlas V. Amazon said it established contact with the entire batch within 90 minutes. This began full-scale deployment of the commercial constellation, with further Atlas V and Falcon 9 missions following.
On 13 November, Amazon introduced the permanent Leo brand, referring to the low Earth orbit network. The programme continued under its new name, while older filings and mission names retained Kuiper.
Later that month, selected businesses began an enterprise preview using production Pro and Ultra terminals. Testing with these customers, including private networking and AWS connections, was another step towards wider service.
- 2026Scaling up
A growing fleet and a broader connectivity plan
Ariane 6 joined the deployment campaign in February. By LA-08 on 2 July, the programme had completed 14 full-scale deployment missions. Amazon’s October reporting showed how its manufacturing output and launched fleet were advancing at different rates.
- Manufacturing milestone
- 1,000+satellites built, reported 8 October
- Deployment progress
- Nearly 400launched, tracker updated 14 October
A built satellite still needs launch preparation, a flight to space, orbit raising and commissioning. Factory output therefore cannot be used as a count of satellites ready to serve customers.
On 14 April, Amazon announced an agreement to acquire Globalstar and a separate satellite-services agreement with Apple. The acquisition announcement expected closing in 2027, subject to conditions and regulatory approvals.
Amazon also proposed a Direct-to-Device system of up to 5,105 satellites, with deployment planned from 2028. This future mobile network would connect compatible devices through operator partnerships. The core broadband service described above uses a dedicated terminal.
A few practical questions
Is Amazon Leo part of Blue Origin?
Leo is an Amazon business. Blue Origin is a separate company founded by Jeff Bezos and is one of the launch providers involved in Amazon’s deployment plans.
Can I use an existing satellite TV dish?
Leo is designed around dedicated customer terminals. A standard satellite TV dish should not be assumed to work as a substitute; follow the equipment requirements for the service offered.
Will Leo improve Wi-Fi in every room?
Leo supplies the connection to the wider network. Indoor coverage depends on your router, building and local network, so a faster satellite link alone does not fix a weak Wi-Fi signal elsewhere in the home.
