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.
As Air Force leaders consider concepts of operations for Collaborative Combat Aircraft, sustainment in the field—and easing that support by using standard parts and limiting variants—should be a key consideration, according to a new study from AFA's Mitchell Institute of Aerospace Studies.
