A Senate Armed Services subcommittee will hear Wednesday from energy and environment officials from across the armed forces, on matters related to the fiscal 2026 National Defense Authorization Act.

The must-pass yearly defense policy bill generally includes provisions related to energy use on military bases, and ongoing military efforts to clean up and regulate the use of per- and polyfluoroalkyl substances or PFAS.
