SpaceOps: ULA, Arianespace Gear Up For Kuiper Launch Blitz

Amazon is preparing its fifth batch of Kuiper broadband satellites for launch next week, with spacecraft processing and integration for the next three missions simultaneously underway in Florida.

Returning to United Launch Alliance (ULA) after a pair of flights with SpaceX, Amazon is aiming to boost its fledgling constellation by 27 more satellites. The mission, designated KA-03, is due to lift off aboard a ULA Atlas V at 8:09 a.m. EDT Sept. 25 from Cape Canaveral SFS Space Launch Complex-41.

ULA plans future Kuiper deployment missions aboard its Vulcan rocket as well, beginning later this year. Amazon also holds launch service contracts with Arianespace and Blue Origin. In total, Amazon plans to operate more than 3,200 satellites as part of Project Kuiper.

Blue Origin has not disclosed its launch manifest beyond the upcoming second flight of the New Glenn heavy-lift rocket. The two-stage, partly reusable rocket is aiming to send a pair of Mars-bound NASA science probes into a gravitationally stable phasing orbit around Lagrange Point 2, located about 1 million mi. from Earth. The spacecraft will linger there until the next ideal planetary alignment window opens in fall 2026. Arrival at Mars is targeted for September 2027.

Arianespace plans to join the Amazon Kuiper delivery fleet later this year or in early 2026. The company is preparing for its third launch of the medium-lift Ariane 62 rocket. That would be followed by either another Ariane 62 with a pair of Galileo global navigation system satellites or the debut of the heavy-lift Ariane 64 with a batch of Kuiper satellites, CEO David Cavailloles said during the World Satellite Business Week conference in Paris this week.

Arianespace retired the Ariane 5 in 2023. More powerful Block 2 variants of the medium-lift Ariane 62 and Ariane 64 are in the works.

ULA conducted the first two Kuiper deployment missions on Atlas V rockets in April and June. SpaceX handled the next two campaigns in July and August.

Amazon is planning for three more Kuiper missions this year, which would bring the constellation to more than 200 satellites, Amazon’s Ricky Freeman, president of government solutions for Project Kuiper, said at the conference.

The company expects to roll out Kuiper broadband communications services in the U.S., Canada, Germany, France and the UK by the first quarter of 2026, he said, with full global coverage anticipated by 2028.
