Amazon Web Services (AWS) has been awarded a $581.3 million cloud computing contract by the US Air Force.

Revealed by the Department of War on January 26, the contract will run until December 7, 2028.

The cloud computing contract has been awarded under the Air Force's Cloud One program, and according to the posting, work will be "performed at the contractor's designated facilities across the contiguous US."

The contractor is currently listed as the Air Force Life Cycle Management Center, Hanscom Air Force Base in Massachusetts.

This is the second such contract to be awarded under the Cloud One program this month, with Microsoft landing a $170.4m cloud computing agreement also set to expire in December 2028.

The Cloud One is the Air Force's cloud platform, separate from the Joint Warfighting Cloud Capability program. Revealed in 2022, Cloud One was described by then CIO of the Air Force, Lauren Knausenberger, as an "$800m service relying on AWS, Microsoft Azure, and Google Cloud (Oracle is promised to come soon), that is available to the Air Force, as well as other parts of the DoD." The first iteration expired in 2024.

In late 2024, AWS revealed it would invest $50 billion in expanding its AI and supercomputing capacity for US government customers. The cloud giant plans to break ground on the projects in 2026, and expects to add nearly 1.3GW of compute capacity across the AWS Top Secret, AWS Secret, and AWS GovCloud (US) Regions at all classification levels by building new data centers.
