The U.S. Air Force issued a proposal (ex post facto) for the withdrawal of the 89,000 acres of land in the Groom Mountains that had already been seized in 1984.
Mid-1980s New dormitories were constructed. Several large water tanks were added to supply the base. Hangar 18 was built near the south ramp. Four "Rubber Duck" temporary aircraft shelters were erected near the Southend for use by TAC during F-117A OT&E. Many new facilities were built and, by the end of the decade the "Rubber Duck" shelters were replaced with metal hangars (Hangars 20 through 23). Runway 14/32 was extended 4,600-feet further southeast of the lakebed because the north end was subject to flooding during the rainy season.
1987 Congress officially authorized the withdrawal of the Groom Mountains.
Spring 1987 Col. James W. Tilley II assigned as commander of DET 3, AFFTC.
1988 President Ronald Reagan signed legislation making the Groom Mountains part of the Nellis Air Force Range until 2003. The Desert Research Institute in Reno was contracted to conduct an archeological survey of the area for renewal of the withdrawal.
Spring 1989 Col. ??? assigned as commander of DET 3, AFFTC.
December 1990 Northrop's stealthy AGM-137 Tri-Service Standoff Attack Missile (TSSAM), based on technology from TACIT BLUE, underwent initial tests.
1991 After several decades of use, Runway 14/32 was becoming too expensive to maintain. AFFTC leadership considered several options, and ultimately decided to build a new parallel runway east of the old one. Construction of Runway 14L/32R began.
Spring 1991 Col. William W. Dobbs assigned as commander of DET 3, AFFTC.
April 1992 The F-117A Combined Test Force relocated its operation from Groom Lake to Site 7 at AF Plant 42 in Palmdale, California.
October 1992 The 6513th Test Squadron Red Hats was inactivated. It was reactivated immediately as the 413th Flight Test Squadron, providing test and evaluation capability for electronic warfare (EW) systems.
When Runway 14L/32R was completed, the old airstrip became Runway 14R/32L. The new runway had no asphalt extension, but an overrun line, extending to "The Hook" was marked on the lakebed. Most of the northern half of Runway 14R/32L was closed, reducing the active runway length to about 10,000 feet.
Spring 1993 Col. Craig P. Dunn assigned as commander of DET 3, AFFTC.
October 1993 The U.S. Air Force filed a notice in the Federal Register seeking to withdraw 3,972 acres of land from public on the eastern perimeter of the DREAMLAND section of the Nellis Air
