The 
first two F-35A strike fighters assigned to Nellis AFB, Nev., arrived this week at the desert base, announced Nellis officials. The airplanes, which will serve as developmental and operational test assets, touched down at Nellis on March 6, according to a base release. They will fly with the 422nd Test and Evaluation Squadron, which will be the first unit to conduct F-35 operational testing, Nellis officials have said. Nellis’ F-35A test force is scheduled to grow 12 aircraft, and the base’s Fighter Weapons School is slated to build up to a fleet of 24 F-35As.

The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
