On January 11, 2017, the NASA Ames Wind Tunnel Historic District was listed in the National Register of Historic Places.
Constructed between 1940 and 1985, the NASA Ames Wind Tunnel Historic District is deemed significant for its associations with aeronautical and aerospace research, the development of aircraft and spacecraft, and the evolution of wind tunnel technology in the United States. This district contains one of the world's greatest collections of wind tunnels, and remains a leading research facility for the aerospace industry.
The NASA Ames Wind Tunnel Historic District's period of significance extends from 1940 to the end of the Space Shuttle program in 2011, although additional significance associated with the ongoing research conducted in the wind tunnels may be realized in the future.
The district consists of five contributing buildings:
- N215: 7- by 10-Foot Wind Tunnel Number 1 and Army Aeromechanics Lab (1941)
- N220: Technical Services Building (1940)
- N-221, N-221B: National Full-Scale Aerodynamics Complex, 40- by 80-foot and
80- by 120-foot wind tunnels, respectively (1944, 1982)
- N-226: 6- by 6-Foot Supersonic Wind Tunnel (1948)
- N-227, N-227A-D: Unitary Plan Wind Tunnel Complex (1956). This complex is also a National Historic Landmark.

Unitary Plan Wind Tunnel Complex:
A National Historic Landmark and Historic Mechanical Engineering Landmark
On October 3, 1985, the Unitary Plan Wind Tunnel complex was nominated and accepted by the Department of Interior as a National Historic Landmark. In May 1996, the American Society of Mechanical Engineers dedicated the complex as an International Historic Mechanical Engineering Landmark.
Unitary Plan Wind Tunnel facts:
- Site Covers 11 Acres
- Construction began in 1951 at a cost of $32 million
- Integration of the basic design embodies three test sections for different speeds so that a single model can be tested over the entire speed range from Mach 0.40 to Mach 3.45
