The Air Force has released its draft environmental assessment for the replacement of the Hawaii Air National Guard’s F-15s with F-22s with a finding of “no significant impact.” The EA, which is available online here (caution: large file), took into account, among a number of differences in operations, the fact that F-22 engines “are more powerful and louder than F-15 engines,” but ANG officials worked with the FAA to develop a landing approach to the joint military-commercial airfield that minimizes noise impacts off base. “There would be essentially no discernible change in off-base noise associated with the replacement of F-15s with F-22As,” states the summary of findings.
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.
