Trying to get a handle on the problems that led to the F-35 program restructure, Rep. Norm Dicks (D-Wash.) asked Feb. 24 at the House Appropriations defense panel hearing on combat aircraft, “Give us a little flavor of what the reason is for this 13-month delay.” In the words of Rear Adm. David Philman, that “flavor” is predominantly the overreliance on modeling instead of actual flight testing. (Hmmm, fly before you buy?) In Scott’s words: “What we’re seeing in the actual flight hasn’t necessarily validated the model. So now we’re continuing to press back and have to go back to more traditional testing for some time until we can get the aircraft mature enough to be more in line with a validated model.”
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.
