Gulf War. As a result of the end of the Cold War, reduced defense budgets were the order of the day. In reviewing its tactical bases and the costs of maintaining them, it was determined that the 37th FW operations from Tonopah required considerable logistics support via commercial air and trucking. All military personnel were permanently assigned to Nellis AFB, Nevada, and were transported once each week by air. Also the security requirements of the F-117A had been lessened with its introduction into the Air Force inventory as an operational weapons system. It was determined that a considerable amount of money would be saved by moving the F-117 operations out of the remote site at Tonopah. 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. The official ceremony for the F-117A arrival at Holloman AFB came on May 9, 1992, setting into motion the final exodus of the Air Force at Tonopah. On June 1, 1992 Det 1, 57 FWW moved from Tonopah to Nellis AFB. On July 8, the 37th FW was inactivated and the 415th FS, 416th FS, and 417th FS had all become part of the 49th Fighter Wing. By August 1992, the TTR Airport was largely in caretaker status with many of the facilities mothballed. Post 1992 After 1992, very little was published about what, if any, aircraft were based there. The facility was placed on caretaker status effective 31 December 1992, however the USAF continued to maintain the runway as active along with the navigation aids remaining open to the DOE and the USAF on an as-needed basis. In July 2001, a commercial McDonnell Douglas MD-82 aircraft landed at the Tonopah Test Range airfield due to a cargo fire warning light, according to an ASRS report. It departed without incident.
