Overview

• NMS began operations on Sept. 29, 2025, distributing notices to early adopters as formal testing gets underway.
• The FAA will run the new service alongside legacy platforms for several months, with USNS retirement slated for February 2026 and the system becoming the single source later in the spring.
• Officials describe the platform as cloud-hosted with near-real-time data exchange, a streamlined interface, and a scalable, resilient architecture.
• More than 12,000 users are scheduled to migrate to the service, which must manage over 4 million notices issued each year.
• Modernization accelerated after repeated outages, including a January 2023 failure that triggered a nationwide ground stop and delayed over 11,000 flights.
