Date of Foundation and Age
- Year of Establishment: The area was first established as the Mojave Anti-Aircraft Range by President Franklin D. Roosevelt on August 8, 1940 . It was renamed Camp Irwin in 1942 and later redesignated as Fort Irwin in 1961 when it became a permanent installation .
- Age: As of 2026, the installation is 86 years old since its original founding in 1940.
- Namesake: The post is named in honor of Major General George LeRoy Irwin, a distinguished commander of the 57th Field Artillery Brigade during World War I .
- History: The area has a much longer history, with Native American settlements dating back nearly 15,000 years.
