The events in Europe in 1939-1940 convinced the United States government that it needed an anti-aircraft training camp and began purchasing land in Georgia for this purpose. In July 1940, the U.S. Government purchased the first 5,000 acres of what was to become Camp Stewart. The Anti-Aircraft Artillery Training Center officially became Camp Stewart in November 1940, though the name was not announced publicly until January 1941. The new camp was named in honor of the Revolutionary War soldier and military hero General Daniel Stewart. The military camp would eventual reach the size of over 280,000 acres.
After the Japanese bombing of Pearl Harbor, new units began to move to the base for training. One of these units was a detachment of Women's Air Service Pilots or WASPs. The WASPs were there to fly planes that towed targets for live fire exercises. This was eventually stopped when radio-controlled airplane targets became available as a safer and more effective way to practice live-fire exercises. As the war progressed more units and soldiers came to Camp Stewart for training. The installation was also used to house German and Italian prisoners of war. After World War II ended, Camp Stewart was reduced to a small group and not increased in manpower until the outbreak of the Korean War.
Camp Stewart became Fort Stewart in 1959 and was re-designated for an Armor and Artillery Firing Center eventually becoming the home of the 3rd Infantry Division. The 3rd Infantry Division has served in World War I, World War II, the Korean War, the Cold War, the Persian Gulf War, and Operation Iraqi Freedom. It has one of the most successful combat records of the U.S. Army, but has lost almost 35,000 soldiers in wars. There have been fifty-five members of the 3rd Infantry Division to be awarded the Medal of Armor while serving their country. One such soldier was Audie Murphy in World War II. Audie Murphy was the most decorated soldier in World War II and the museum has an exhibit in his honor.
The museum is planning to expand in the future to include displays of past military vehicles and expanding exhibits related to the history of the 3rd Infantry Division. They are also planning to expand to include a gallery featuring Airfields and Aviation. The museum website also included links to information on the histories of the 3rd Infantry Division, Fort Stewart, and Hunter Army Airfield. They also have an online museum that showcases artifacts that archaeologists have discovered on the military reservation that date from the Paleoindian Period (11,500-9,500 BC).
