The United States Federal Communications Commission on Tuesday approved Amazon’s request to launch 4,500 additional satellites, increasing the company’s planned constellation as it competes with Elon Musk’s SpaceX.

With the approval, Amazon’s low Earth orbit satellite network will total about 7,700 satellites.

Since April, the company has already deployed more than 150 satellites using various rocket providers.

Amazon aims to start offering satellite internet through its service, Project Kuiper, later this year, a project first announced in 2019.

Amazon’s upcoming satellites mark the second generation of its orbital system and will operate at altitudes up to roughly 400 miles. The new additions will support more frequency bands and expand Project Kuiper’s coverage areas.

The FCC requires Amazon to launch half of the approved satellites by February 10, 2032, and the rest by February 10, 2035.

Meanwhile, Amazon is also racing to meet an FCC deadline to launch 1,600 of its first-generation satellites by July 2026.

Last month, the company requested that the agency extend the deadline to July 2028 or waive it entirely.

The FCC has not yet made a decision.

Amazon cited factors beyond its control—such as a short-term shortage of rockets for launches, as reasons it may miss the original deadline.
