Department of Defense Should Resolve Major Issues Regarding Reengining the KC-135 Aircraft Before Continuing the Program

A review was undertaken of the Air Force's KC-135 tanker aircraft reengining modification program. The reengining modification is a complex effort involving extensive development and testing that will reportedly provide several benefits. These include increasing KC-135 survivability, safety, fuel efficiency, and fuel off-load capability. The reengined KC-135 will also be quieter and produce fewer pollutants. The purpose of the review was to determine the program's status and to identify unresolved pertinent issues. The issues addressed included questions concerning the program's pace, cost effectiveness, need, and affordability.
