Vulcan VC6L | Amazon Leo (LV-01): Launch Time & How to Watch (30 Sep 2026)

What is launching?

A United Launch Alliance Vulcan VC6L rocket is scheduled to launch the Amazon Leo (LV-01) mission from Space Launch Complex 41 at Cape Canaveral Space Force Station, Florida. This flight uses the powerful VC6L configuration of Vulcan Centaur, featuring six solid rocket boosters and the long-payload fairing — the heavy-lift variant built for demanding orbital deployments.

The mission marks a milestone launch for Amazon's low-Earth-orbit broadband constellation, formerly known as Project Kuiper and now branded Amazon Leo. ULA is among the primary launch providers contracted to loft the constellation's satellites into orbit.

When is the Vulcan Amazon Leo launch?

The launch is targeted for 30 September 2026 at 00:00 UTC. The status is currently listed as TBD, so the date and time may shift as vehicle processing, range availability and payload readiness are confirmed. Always check the latest timing before heading out to watch.

What is the payload?

The payload is a batch of Amazon Leo broadband satellites. Amazon Leo is designed to deliver low-latency, high-speed internet from low Earth orbit, competing directly with other broadband megaconstellations. Once fully deployed, the network is intended to serve residential customers, businesses and government users across the globe, with a focus on unserved and underserved regions.

ULA's Vulcan rocket, with its high-energy Centaur upper stage, is well suited to placing multiple satellites into precise orbital planes for constellation build-out. The VC6L configuration provides the maximum lift capability in the Vulcan family, ideal for heavy stacks of spacecraft.

About the Vulcan VC6L rocket

Vulcan Centaur is ULA's next-generation launch vehicle, replacing the long-serving Atlas V and Delta IV. It is powered by two BE-4 main engines burning liquefied natural gas and liquid oxygen, augmented by up to six strap-on solid rocket boosters. The VC6L designation indicates six solid boosters and the long (15.5 m) payload fairing.

The upper stage is the Centaur V, which uses two RL10 engines and is one of the most capable high-energy stages flying today. This combination makes Vulcan a versatile workhorse for commercial constellations, national security payloads and interplanetary missions.

How to watch the launch live

United Launch Alliance typically provides a live webcast beginning shortly before liftoff, carried on its official channels. Because this launch lifts off from Florida's Space Coast, spectators in the Cape Canaveral and Titusville areas often get excellent views of the ascent, weather permitting.

You can also follow the countdown and track the vehicle in real time on Cosmik. Explore our rocket launch schedule for the latest timing, and dive into the provider launch hubs and our Cape Canaveral launch page for site-specific coverage.

• Confirm the latest NET time before the launch window opens.
• Watch ULA's official live stream for the countdown and liftoff.
• Follow the rocket and the deployed satellites on the Cosmik live 3D map.

Why this mission matters

Each Amazon Leo launch expands a constellation that aims to bring global broadband coverage from low Earth orbit. As the network grows, you'll be able to visualize its satellites alongside other constellations on our interactive map.
