As if the 
airlift numbers weren’t sobering enough, USAF says that the typical ANG F-16 squadron today has 15 fighters. The optimum number is 24, or, in the case of experienced ANG forces, 18 per squadron. Eighteen would ensure there are sufficient fighters to perform a given mission. Unless ANG redistributes airframes among fewer units, normal aircraft attrition will take the number of F-16s per ANG squadron in 2017 down to 6.3. Again, says the Air Force, very inefficient.
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.
