Area 25 (Nevada National Security Site)

[1] Area 25 is commonly called "Jackass Flats" because it is composed primarily of a shallow alluvial basin by that name.

The complex includes three test stands, the Engine Maintenance, Assembly, and Disassembly (E-MAD) facility, the Reactor Maintenance, Assembly, and Disassembly (R-MAD) facility, a control point/technical operations complex, an administrative area and a radioactive material storage area.

High-level radioactive materials handling studies were carried out at the BREN Tower, recently demolished by implosion in Jackass Flats, where it was moved after 1963 for the High Energy Neutron Reaction Experiment (HENRE) series.

[6] Air Force Lieutenant General Robert M. Bond was test flying a MiG-23 from the secret U.S. fleet of MiGs held at Area 51.

Demolition activities for the radiologically contaminated portions of the R-MAD Facility were initiated in October 2009 and completed on July 15, 2010.
