# USAF Restarts Sentinel SEIS Town Halls

The U.S. Air Force plans to restart community town halls in November 2026 while preparing a supplemental environmental impact statement (SEIS) for the restructured LGM-35A Sentinel program, following its 2024 Nunn-McCurdy critical cost breach and a shift to new Sentinel silos. The engagement concerns the program’s revised basing plan; the available information does not provide a town-hall schedule, solicitation, contract value, or procurement contact.

- Contractors can use the forthcoming engagement details to identify opportunities to provide input on the revised basing plan and related environmental review.
- The SEIS is a program-planning and environmental review step, not an announced contract opportunity; no new award or solicitation is identified.
- Northrop Grumman is identified as the program’s prime contractor and Boeing as incumbent in the extracted entities. Businesses seeking a role should distinguish existing program positions from any future procurement, which is not specified here.
