The 2007 defense authorization bill confirms Congressional desire to keep a second engine program going for the F-35 Joint Strike Fighter, despite Pentagon objections. The authorization act requires DOD to keep two engines in development and procurement and to provide three separate and independent cost analyses of the JSF engine program. The measure slows somewhat advance procurement, citing program delays and concern over too rapid development. (The companion spending bill funds the alternate engine and advance procurement for 12 JSFs.)
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.
