Overview
- Sandia National Laboratories and the NNSA ran multiple flight tests Aug. 19–21 at Nevada’s Tonopah Test Range using F-35A aircraft generated from Hill Air Force Base.
- The releases used B61-12 joint test assemblies that match stockpile bombs in form and function but contain no nuclear material.
- Engineers executed the first thermal preconditioning of a B61-12 test assembly before F-35 carriage to verify performance in real-world environments.
- Sandia said these are the only B61-12 stockpile flight tests conducted from an F-35 to date, calling the results a major integration milestone.
- Photos and video show personnel loading two inert B61-12s into an F-35 on Aug. 19, and officials emphasized the activity does not involve explosive nuclear testing.
