The Curtiss OX-5 engine powered mostly trainer-type aircraft such as the Curtiss JN-4 “Jenny” during World War I and continues to be a popular restoration project today. This type engine has the distinction of being the first mass-produced U.S. designed aircraft engine. Introduced in 1912, the OX series of engines continued to be refined with the liquid-cooled, 90 hp, V8 Curtiss OX-5 introduced in 1915.

In 1929, the Curtiss OX-5 engine powered 38% or 2,510 of 6,631 licensed airplanes in the United States.

Amelia Earhart and Charles Lindbergh logged many of their early flying hours piloting aircraft powered by an OX-5.

Restored and donated to the Museum by the Texas Wing of the OX5 Aviation Pioneers, this Curtiss OX-5 enjoys a place of distinction in the Dallas Love Field Gallery. The US Army nameplate includes “S.C. No. 12767, Factory No. 3321”. Overhead hangs a Curtiss JN-4 “Jenny” that served at Love Field during WWI.
