Amazon has reached a major milestone in the rollout of its low Earth orbit satellite internet network, announcing that it now has enough satellites in space to begin offering initial internet service later this year.

The company successfully launched 29 additional satellites at about 12:30 a.m. ET on Thursday aboard a United Launch Alliance Atlas V rocket. The latest deployment increases Amazon’s satellite constellation to more than 390.

According to the Amazon’s Vice President of Business and Product for its LEO network, Chris Weber, the expanded constellation is sufficient to provide continuous coverage across its initial service areas.

The achievement marks an important step in Amazon’s efforts to compete with SpaceX’s Starlink in the rapidly growing low Earth orbit satellite internet market.

The development marks a significant milestone in Amazon’s efforts to position its LEO satellite network as a rival to SpaceX’s Starlink in the fast-growing low Earth orbit internet market.

Amazon began an enterprise preview of the service for selected businesses in November, but it has not yet rolled out commercial access for consumers or government customers.

The company said its initial commercial service will likely be available only in select regions, with future satellite launches expected to expand network coverage and increase capacity.
