The Center for Strategic and Budgetary Assessments, a defense think tank, held a Capitol Hill seminar on Nov. 10 (DR, 11/11/05). One glow-in-the dark CSBA recommendation was that the Air Force should reduce spending on fighters in favor of other systems, including long-range bombers. CSBA’s Michael Vickes noted that USAF’s fleet comprises mostly nonstealthy B-52 and B-1B aircraft. He produced this graphic (click to enlarge). Note, however, that the chart begins in 1999. That leaves out the heavy investment in the B-2 and B-1B bombers in the 1980s and 1990s. Also, the sand chart includes Navy as well as Air Force fighters. Distorts the case a little bit.
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.
