Now known as Pinal Air Park. From Wikipedia:

Built in 1942 by the Sundt & Del Webb Construction Companies and opened in March 1943, the facility was known as Marana Army Air Field. During World War II, the airfield was under the command of the 389th Army Air Force Base Unit, AAF West Coast Training Center and used as a training base, as part of the 50,000 Pilot Training Program.

Marana conducted basic flight training & the training of transport pilots in instrument flying and navigation, being the home of the 3024th (Pilot School, Basic). Chinese pilots were also trained there. Five satellite airfields were established for Marana during World War II: Picacho Aux #1, Rillito Aux #2 (currently reused as Marana Northwest Regional Airport), Coronado Aux #3, Avra Aux #4, and Sahuaro Aux #5 (currently El Tiro Gliderport).

The infrastructure installed at Marana during World War II was extensive. This included water, sewer, and gas systems that were still used until some problems developed in the 1990s. There was also a massive storm drain system. The airfield also had a railroad spur line and railroad station.

The airfield was briefly closed after WWII, but later reopened and used by military groups, The Central Intelligence Agency, and commercial airlines for a variety of purposes.
