CAPE CANAVERAL SPACE FORCE STATION, FL – The most powerful version of the United Launch Alliance (ULA) Atlas V rocket is sits poised for liftoff from Florida’s Space Coast on Monday evening April 28 ready to blast the inaugural batch of Amazons Kuiper broadband constellation of commercial internet comsats to orbit – setting up a new system for direct head-to-head competition with the already well-established SpaceX Starlink satellite system.

The Atlas V 551 rocket is targeting liftoff from Space Launch Complex-41 at 7:00 p.m. EDT, on the Kuiper-1 mission delivering the 1st batch of 27 operational Amazon Kuiper commercial comsats to orbit – thereby initiating the Kuiper orbital constellation of broadband internet satellites.

The Atlas V will launch in its most powerful 551 configuration known as “The Bruiser” – spewing over 2.5 million pounds of liftoff thrust from the first stage powered by a dual nozzle RD-180 engine and 5 strap on solid rocket boosters SRBs.

The Atlas V will launch on a northeasterly trajectory up the US East Coast
Kuiper-1 marks the first of many full-scale launches in service of Amazon’s Project Kuiper under contract to ULA

The Kuiper constellation will eventually comprise over 3200 satellites in low Earth orbit (LEO).
The Kuiper satellites will be launched across 98 orbital planes at 590 km, 610 km and 630 km in altitude.

These first 27 Kuiper satellites will be deployed at an altitude of 280 miles (450 kilometers) above Earth.
The Amazon-built Kuiper spacecraft are encapsulated in a 17.7-ft (5.4-m) diameter medium payload fairing. The PLF is a sandwich composite structure made with a vented aluminum-honeycomb core and graphite-epoxy face sheets. The bisector (two-piece shell) PLF encapsulates both the Centaur and the satellites.
The Atlas V vehicle height with the 5-meter medium PLF is approximately 205 ft (62.5 m).
