A US Air Force F-16C dropped an inert B61-12 nuclear bomb during a development flight test by the 422nd Flight Test and Evaluation Squadron at Nellis AFB, Nevada, on March 14, 2017, demonstrating the aircraft's capability to deliver the weapon and testing the functioning of the weapon's non-nuclear components, including the arming and fire control system, radar altimeter, spin rocket motors and weapons control computer. The test was conducted under a life-extension program for the B61-12. The non-nuclear bomb assembly used for the flight test was designed and manufactured by Sandia National Laboratories and Los Alamos National Laboratory.
