United Launch Alliance delayed the fifth Atlas V 551 launch for Amazon Kuiper’s Kuiper Leo 5 mission on 28 March 2026.

PlanValue 4.0Mar 30, 2026ULA rinvia il lancio Atlas V per satelliti Amazon Kuiper

United Launch Alliance delayed the Atlas V 551 launch because of predicted inclement weather in the launch area.

The Atlas V 551 rocket and the Kuiper Leo 5 spacecraft were in nominal condition after the delay.

CapabilityPlanValue 3.0Mar 30, 2026ULA rinvia il lancio Atlas V per satelliti Amazon Kuiper

ULA rolled an Atlas V rocket to the launchpad for the Amazon Leo LA-05 mission.

PlanValue 4.0Mar 28, 2026LA-05 is the first Leo Atlas launch to carry 29 satellites instead of 27. This is possible thanks to the use of the RL10C-1-1 upper stage engine, which has more performance then the RL10A-4-2. The additional 2 satellites make LA-05 the heaviest payload ever launched by Atlas V.

The Atlas V 551 launch vehicle and the Amazon Leo spacecraft are healthy.

CapabilityValue 3.0Mar 28, 2026New hazard area's have been released for the LA-05 mission, and they indicate that the launch has been rescheduled for NET April 4th at 05:45 UTC. A day-for-day delay would mean that the LA-06 mission, which was set for NET April 24th, should now be NET April 30th.

The RL10C-1-1 upper stage engine gives Atlas V more performance than the RL10A-4-2 engine.
