NELLIS AIR FORCE BASE, Nev. (AFNS) —  

Two F-35A Lightning II aircraft recently released B61-12 Joint Test Assemblies, or JTAs, during the F-35A’s first Full Weapon System Demonstration, completing the final flight test exercise of the nuclear design certification process.

The 422nd and 59th Test and Evaluation Squadrons led Air Combat Command’s portion of the test effort, with Airmen from the 57th Aircraft Maintenance Squadron, 926th Aircraft Maintenance Squadron and Bolt Aircraft Maintenance Unit leading all maintenance efforts. Once airborne, test pilots flew to the Tonopah Test Range and released two B61-12 JTAs from operationally realistic flight envelopes. This event was the first release of the most representative B61-12 test asset from an operationally-representative F-35A.

“The B61 series weapons are tactical gravity nuclear weapons that can be used on Dual Capable Aircraft like the F-15E (Strike Eagle) and F-16C/D (Fighting Falcon),” said Lt. Col Daniel Jackson, Headquarters ACC Strategic Deterrence and Nuclear Integration division chief. “Having a 5th Generation DCA fighter aircraft with this capability brings an entirely new strategic-level capability that strengthens our nation’s nuclear deterrence mission.”

The nuclear certification is broken into two phases: nuclear design certification and nuclear operational certification. This test is considered the graduation flight test exercise for the F-35A nuclear design certification and concludes on-aircraft testing for the initial nuclear certification effort. The test data received from this event is currently under analysis and review by the Department of Defense and Department of Energyto ensure the F-35A and B61-12 JTAs performed correctly throughout all phases of the operation.
