Amazon Leo, formerly known as Project Kuiper, is a mega constellation of satellites in Low Earth Orbit that will offer broadband internet access, this constellation will be managed by Kuiper Systems LLC, a subsidiary of Amazon. This constellation is planned to be composed of 3,276 satellites. The satellites are projected to be placed in 98 orbital planes in three orbital layers, one at 590 km, 610 km and 630 km altitude.

29 satellites are carried on this launch.

Rocket Launch: Amazon Leo 6

Official Webcast

Watch live coverage of the launch of a United Launch Alliance Atlas 5 rocket with a batch of 29 satellites for Amazon's Leo internet service on Monday, April 27, 2026. Liftoff is scheduled during a 29-minute launch window that opens at 8:52 p.m. EDT (0052 UTC). The rocket will take a north-easterly trajectory on departure from Florida's Space Coast.

Amazon’s LEO satellite internet constellation, originally called Project Kuiper, is designed to rival others, like SpaceX’s Starlink and Eutelsat's OneWeb.

The Leo 6 mission features the most powerful Atlas 5 configuration, the 551, equipped with five solid rocket boosters from Northrop Grumman.

Commentary will be provided by Spaceflight Now's Will Robinson-Smith, starting approximately one hour prior to liftoff.
