 Tactical Air Command also believed, while Tonopah Airport was adequate for testing and development of aircraft, it was unsuitable as a fully operational tactical base.Also, the Air Force wanted to retire the F-15A/B Eagles operated by the 49th Fighter Wing at Holloman AFB, New Mexico, most of which were manufactured in the mid 1970s and were costing more and more to operate.As a result, plans were put in place to construct suitable facilities for the F-117A at Holloman AFB and to retire the F-15A/B models of the 49th FW.
