Amazon Leo

Amazon Leo is a low Earth orbit satellite constellation designed to deliver fast, reliable internet beyond the reach of existing networks.

Standing 215 feet (65.5m) tall and configured as a low Earth orbit heavy-lifter, this will be the first Vulcan to use the full complement of six side-mounted solid rocket boosters for max liftoff thrust, the LEO-optimized Centaur V upper stage sized to suit Amazon requirements and a 70-foot-long (21m) payload fairing to encapsulate the large number of satellites. https://t.co/mChVNb0aEc

It's roll day!

A dedicated processing lane to launch Amazon's advanced broadband satellite constellation using United Launch Alliance optimized heavy-lifting Vulcan rockets and purpose-built infrastructure is ready to support its first launch at Cape Canaveral Space Force Station, Florida.

The rollout of the Vulcan Leo 1 rocket from the Amazon Vertical Integration Facility (VIF-A) to Space Launch Complex-41 marks the start of dual launch processing lanes for ULA operations at the Cape.

Launch of this 10th ULA mission for the Amazon Leo global broadband network is targeted for Friday during a window opening at 12:54 p.m. EST (1754 UTC).

Teammates representing United Launch Alliance, Amazon, U.S. Space Force and FAA gathered for the Vulcan Leo 1 Launch Readiness Review and declared the rocket, its payload and mission-support assets GO for liftoff Friday at 12:54 p.m. EST (1754 UTC).

Our biggest Leo payload yet is heading to the pad.

Leo Vulcan 1 (LV-01), our first launch on ULA's Vulcan rocket, is targeting liftoff this Friday, Nov. 13 at 12:54pm ET, carrying 40 satellites on the first of 38 missions with @ulalaunch.

New Amazon-funded infrastructure at the Cape enables ULA to prep two Vulcans at once, so LV-02 can follow within weeks of a nominal LV-01 mission.

One week to launch! Standby for the livestream of our Vulcan rocket carrying the Amazon Leo 1 mission. https://t.co/VFhcvXzR2q

Fresh @AmazonLeo logo going onto Ariane 6's 20-meter-tall fairing ahead of our next launch with @Arianespace. Insider tip: the color is "krypton," not purple...inspired by the krypton-fueled thruster on each Leo satellite. Still not tired of seeing it. Thanks to the Leo and Ariane teams getting this one ready to fly.

Leo Vulcan 1 (LV-01) update:

Our first mission on @ulalaunch's Vulcan rocket is set for Friday, Nov. 13, pending range approval. All 40 Leo satellites—our largest payload to date—have been integrated with Vulcan inside Amazon's vertical integration facility (VIF-A) at the Cape, and teams are working through final processing ahead of launch from SLC-41.

More @AmazonLeo testing, with Leo Pro antennas installed for 1,000+ employees across multiple countries. Huge thanks to the team members volunteering their rooftops to help us test and improve. Learning a lot from each one.

Leo Vulcan 1 (LV-01) payload on the move.

LV-01 is the first of 38 Leo missions on @ulalaunch’s heavy-lift Vulcan rocket, and last week, teams successfully transported the 40-satellite payload—encapsulated inside a 70-foot-tall fairing—to the new Amazon Vertical Integration Facility (VIF-A) at Cape Canaveral.

Sunset over what we call a customer terminal or “CT” farm. One of the many ways we're working to expand network testing. The @AmazonLeo team stood this up quickly, and we’re already learning a lot about how to make the service better for customers.

1,000+ satellites built. 🛰️

In Kirkland, Washington, our factory continuously builds, tests, and ships @AmazonLeo satellites. In Cape Canaveral and Kourou, satellites for our missions on Vulcan and Ariane 6 are stacked on their dispensers ahead of launch.

Take a look inside the factory with a mission to help bring fast, reliable, and affordable internet to customers and communities around the world. ⬇️

[Panos Panay @panos_panay]

A single @AmazonLeo satellite is made up of roughly 4 million individual components and weighs more than 1,000 pounds. When we started, it took weeks to build just one. Now, we’ve built more than 1,000.

Next up: Another Ariane 6 mission and our first launches on Vulcan.

Really enjoyed this story about the 1K milestone. Check it out: https://t.co/IL7zQ5FMzE

Leo Europe 4 (LE-04)

Our fourth mission with @Arianespace is set for no earlier than (NET) November 23 from Europe’s Spaceport in Kourou, and the launch campaign is underway with all 36 satellites onsite and stacked on the dispenser.

Satellite production, by the numbers:

✅ 172,000 square feet of production space
✅ 500+ skilled engineers and technicians
✅ 4 million individual components per satellite
✅ 1000+ satellites complete, with nearly 400 launched across 14 missions
✅ 100+ satellites fully stacked on dispensers for our first Vulcan missions with @ULAlaunch and next Ariane 6 flight with @Arianespace

[Amazon Leo @AmazonLeo]

1000+ Leo satellites complete, with hundreds on standby for launch.

From two prototypes to a full-rate production line, every Leo satellite is designed, built, and tested at our factory in Kirkland, WA. Getting here meant standing up a satellite factory from scratch, compressing test cycles that traditionally take months into days, and learning from every piece of hardware we broke along the way.

We’re partnering with Uztelecom, the leading telecommunications operator in Uzbekistan, to bring satellite connectivity to remote and hard-to-reach communities across the country.

UZ-SAT will serve as an authorized distributor of Amazon Leo, complementing Uztelecom's extensive terrestrial network and helping close the digital divide for millions of people.

We've secured six more Ariane 6 launches with @Arianespace, bringing the total number of Leo Europe missions to 24—enough to send 800+ Leo satellites into orbit.

Nadine started at an Amazon delivery station. Jessica started at a fulfillment center. Today, Nadine assembles solar panels on Leo satellites. Jessica tests components in our space simulation lab.

Both earned aerospace certifications at no cost to them through Amazon's Career Choice program, and are now one of thousands of people at Amazon helping build, launch, and operate our growing satellite network.

Most internships end with a doc. This one ended with a rocket launch. Thanks for spending your summer with us!

[Panos Panay @panos_panay]

Love seeing some of the cool things our interns experienced during their time at @amazon. Especially big moments like @AmazonLeo's LA-08 mission. Congrats to the 2026 intern class on a successful summer. Pumped to see what you do next!
