Amazon on Tuesday announced the largest rocket deal in the history of the commercial space industry, signing agreements with 3 companies for 83 launches of its Project Kuiper internet satellites, CNBC writes.

Amazon signed launch contracts with United Launch Alliance, Arianespace and Blue Origin, a space company owned by Jeff Bezos.

Project Kuiper is Amazon’s plan to build a network of 3,236 satellites in low Earth orbit to provide high-speed internet anywhere in the world.

When it comes to the details of the deals, Amazon has signed contracts for 38 satellite launches with United Launch Alliance (ULA), a joint venture between Boeing and Lockheed Martin ; 18 satellite launches with Europe’s Arianesace; and 12 with Blue Origin with the option for up to 15 additional launches.

In 2020, Amazon said it will invest more than $10 billion in the program.

The company is set to begin testing a pair of Kuiper satellite prototypes, scheduled to launch later this year on an ABL Space RS1 rocket, before moving on to launching operational satellites.

U.S. Federal Communications Commission (FCC) rules require Amazon to deploy half of its planned satellites in orbit within 6 years, which is about 1,600 satellites by July 2026.

ULA will use its Vulcan rockets to launch 38 satellites, in addition to the 9 Atlas V rocket launches for Kuiper, which Amazon purchased last year. ULA’s Vulcan rocket has yet to launch, but its debut mission is set for later this year.

European rocket maker Arianespace will perform 18 Kuiper launches on future Ariane 6 rockets, which are also set to debut later this year.

Finally Blue Origin will use its New Glenn rockets to launch 12 Kuiper missions. While Blue Origin does not currently have an official target date for New Glenn’s first launch, the rocket is reportedly expected to launch in 2024 or later.

The company has not publicly disclosed the price of New Glenn launches, but 2 years ago Arianespace estimated Blue Origin’s rocket to cost $68 million per launch. Although both companies were founded by Bezos, Blue Origin is separate from Amazon.

As for Blue Origin’s main competitor SpaceX, Bezos and Musk have long been in dispute with federal regulators over their Kuiper and Starlink satellite internet networks.

SpaceX is well ahead of Amazon in the race to provide internet access from space, having so far launched some 2,000 Starlink satellites that serve about 250,000 subscribers.

But Amazon is banking on its global presence to close the gap. The Kuiper satellite network will utilize Amazon’s global logistics and operations capabilities, as well as the Amazon Web Services (AWS) network and infrastructure.
