Amazon Leo surpasses 390 satellites, eyes initial service later this year
Amazon.com Inc. deployed 29 satellites on a United Launch Alliance Atlas V rocket, bringing its total Leo constellation count to 396. The company confirmed it has completed enough launches to support initial service later this year, though specific regions were not disclosed. Amazon has booked roughly 100 launches worth at least $82 billion with providers including ULA, Blue Origin, Arianespace, and SpaceX.

Amazon.com Inc. is positioned to begin initial internet service with its Leo broadband satellite network later this year after its latest launch pushed the constellation’s count past 390. The company deployed 29 satellites on a United Launch Alliance (ULA) Atlas V rocket, marking the 14th mission for the project. This launch brought the total number of deployed Leo satellites to 396, moving Amazon closer to its goal of providing continuous service across initial latitudes.
Deployment Progress and Milestones
The latest mission lifted off from Florida, contributing to a broader deployment target of more than 3,200 satellites. Amazon Leo chief Chris Weber stated that the company has completed enough launches for initial service this year, with future missions focused on adding coverage and capacity. Weber noted that work remains to raise the new satellites to their assigned altitude. Spaceflight analyst Jonathan McDowell counted 394 satellites in orbit out of 398 launched since April 2025.
Launch Vehicle Strategy and Challenges
Amazon has relied heavily on the Atlas V rocket, which has launched 224 Leo satellites with a 100% success rate across eight missions. The company now plans to transition to ULA’s Vulcan rocket, which is booked for at least 40 Leo missions. However, both the Vulcan and Blue Origin’s New Glenn rockets are currently grounded. The New Glenn rocket exploded on its launchpad last month, while Vulcan faced a solid rocket motor separation issue in February. ULA spokeswoman Jessica Rye indicated that Blue Origin engineers are collaborating on the investigation into the BE-4 engines used by both rockets.
Competitive Landscape and Future Plans
Amazon faces significant competition from SpaceX’s Starlink, which currently operates a much larger constellation and has secured major aviation customers. Despite this, Amazon has begun landing partners such as Delta Air Lines Inc. The company has roughly 100 rocket launches booked, worth at least $82 billion, with ULA, Blue Origin, Arianespace, and SpaceX. This includes the use of SpaceX’s Falcon 9, highlighting the complex dynamics of the satellite broadband race.
| Launch Provider | Missions Booked | Status |
|---|---|---|
| United Launch Alliance (Atlas V) | 8 completed | Active |
| United Launch Alliance (Vulcan) | 40+ | Grounded |
| Blue Origin (New Glenn) | Multiple | Grounded |
| SpaceX (Falcon 9) | Multiple | Active |
| Arianespace | Multiple | Active |
How will the extended grounding of the Vulcan and New Glenn rockets impact Amazon's timeline for deploying the remaining 2,800+ satellites?
Can Amazon secure enough aviation and maritime partners to effectively compete with SpaceX's Starlink given its first-mover advantage?
What is the contingency plan if the BE-4 engine investigation significantly delays the resumption of Vulcan and New Glenn flights?
