The Langley Full Scale Tunnel was put into service by the National Advisory Committee for Aeronautics (NACA), NASA’s predecessor, in May 1931. Construction took only fifteen months, at a cost of $900,000. Current replacement value for this wind tunnel has been conservatively estimated at $35,000,000. At the time of its commissioning it was by far the largest wind tunnel ever built, and is still one of the four largest in the world. In its day, it was considered an extremely innovative design because of its double return configuration, and the location of its dual fans.

An amazing range of tests have been undertaken in this facility which have greatly contributed to the advancement of the US. aerospace industry. By the way of example, a listing of full-scale tests programs would include: aerodynamic performance measurements of military and civilian biplanes, drag reduction tests on all major W.W.II monoplane fighters, and general aerodynamics of general aviation aircraft, including engine installation aerodynamics and stalling characteristics. Model tests included high-lift approach and landing tests of supersonic transports, extensive high angle of attack testing of all current front-line US jet fighters, sub-scale parachutes, and parafoils, airships, submarines, and at least one building (curiously, itself a wind tunnel complex). Unusual or unique test capabilities included forced oscillation dynamic stability measurements, free-flight testing of powered and tethered models, and a variety of V/STOL and rotor craft work.

Because of its significance to the advancement of aeronautical research, this wind tunnel has been designated a National Historical Landmark by the US Department of Interior’s National Parks Service. During the period of operation by NASA, the facility name was changed from the Full Scale Tunnel to the 30 by 60 tunnel, and is often referred to by that name today.

Due to the ending of the "Cold War," NASA’s budget began to experience strong downward pressure, forcing NASA to adapt to the changing environment. As a result, a number of major facilities at Langley have been closed, with the 30 by 60 tunnel closing in October of 1995. Virtually all data acquisition systems and much ancillary equipment was removed from the LFST for relocation to other NASA tunnels. The most serious reduction in useful facility capability came about from the removal of the Small Model Support system, which has been reworked by NASA for use in their 14-ft. by 22-ft. tunnel.

ODU recognized that an important national capability was being lost, and that opportunities existed for an innovative privatized operation. Around the time of the closure, ODU therefore initiated negotiations with NASA Langley Research Center.
