Amazon Leo, formerly Project Kuiper, is Amazon’s low Earth orbit satellite network, aiming to deliver fast, reliable internet to customers and communities beyond the reach of existing networks. Our initial satellite constellation will include more than 3,000 spacecraft, which we began deploying in April 2025 when we sent our first 27 satellites into space. That mission was the first of more than 100 to deploy our constellation.
Follow along here for updates on recent and upcoming Amazon Leo missions.

February 12: Amazon expands satellite constellation with successful LE-01 mission
Arianespace successfully deployed another batch of Amazon Leo satellites into orbit at 8:45 a.m. PST | 4:45 p.m UTC on Thursday, February 12. Named LE-01 (Leo Europe 1) for Amazon's first launch on Arianespace's Ariane 6 rocket, the mission flew in its more powerful four-booster configuration, Ariane 64. It deployed 32 satellites—the largest Amazon Leo payload launched to date—bringing the total number of spacecraft in the constellation to more than 200 satellites. As the first heavy-lift mission on our 2026 manifest and the first of 20+ launches planned for the year, LE-01 demonstrates how heavy-lift capability allows us to deploy more satellites per launch and scale the constellation faster.

From there, we perform initial satellite health checks and prepare to raise the satellites to their assigned altitude of 392 miles (630 km), where they will be fully commissioned as part of our operational satellite constellation.
LE-01 marks our first successful launch of the year and our first mission with Arianespace. These missions continue to expand the constellation and increase coverage and capacity as we prepare to begin service rollout. We’re continuing to increase production, processing, and launch rates as we look ahead to a higher cadence of missions throughout 2026, and will have more to share on subsequent missions as they approach.
