The
National Advisory Committee for Aeronautics (
NACA) was a
U.S. federal agency founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research. On October 1, 1958, the agency was dissolved, and its assets and personnel transferred to the newly created
National Aeronautics and Space Administration (NASA). NACA was pronounced as individual letters, rather than as an
acronym (and after NASA first came into being, it too was vocalized as individual letters as well).
