Hawthorne Army Depot, Military ammunition depot in western Nevada, United States.

Hawthorne Army Depot is a U.S. Army ammunition storage depot south of Walker Lake in western Nevada, covering 147,000 acres. Its 2,427 low, earth-toned bunkers stand in long straight rows across pale tan ground, forming rectangular grids split by wide unpaved avenues. A separate industrial area of low buildings and flat-roofed shops holds the command headquarters and engineering facilities.

The depot was established in 1930 following a major explosion at another naval ammunition facility to create a safer storage system. During World War II, it became a crucial supply center employing thousands of workers.

The facility shaped Hawthorne by drawing military and civilian workers who built a skilled workforce in ammunition logistics. The local community's identity and economy remain closely tied to this military industrial purpose.

The depot is a working military site, not a visitor attraction; entry is limited to authorized military and contractor personnel. It lies directly south of Walker Lake, around the town of Hawthorne in western Nevada, and is run by an independent contractor under an agreement with the U.S. government. Staffing is partial in peacetime but can be expanded quickly.

The depot's stored ammunition was marked with the code "HAW" followed by the last two digits of the year it was examined and repacked, such as "HAW 50" for 1950. The site also destroyed the U.S. stockpile of M687 chemical artillery shells in 1998–1999, separating 505 short tons of binary precursor chemicals.
