 once stood where the highway intersection is today (the hospital moved to its present location in 1948). In 1914 a regimental-sized cantonment area was constructed (near Richardson Theater). The Hawaiian Ordnance Depot was built in 1917 as a separate post (near today's post exchange). In 1921 the Hawaiian Department moved to Fort Shafter from downtown Honolulu. Finally, a new area was constructed in 1940 for Signal Corps elements.
War came to Fort Shafter on December 7, 1941, where the Hawaiian Department commander, Lieutenant General Walter C. Short, occupied Quarters 5. One soldier, Corporal Arthur A. Favreau, 64th Coast Artillery (Anti-Aircraft), was killed on post by an errant Navy shell. Fort Shafter became a busy headquarters and the barracks on Palm Circle were converted to offices. The major headquarters was named successively U.S. Army Forces, Central Pacific Area (1943–44); U.S. Army Forces, Pacific Ocean Areas (1944–45); and U.S. Army Forces, Middle Pacific (1945–47). In 1944 the Army Corps of Engineers erected the "Pineapple Pentagon" (buildings T-100, T-101, and T-102) in just 49 days. Two large fishponds were filled in to form Shafter Flats.

For most of the next half century, Fort Shafter has remained the senior Army headquarters for the Asia-Pacific region. In 1947 the headquarters was renamed U.S. Army, Pacific. The post continued to adapt to meet the Army's evolving requirements. In the early 1960s the new Moanalua Freeway

 split the post in two. In 1974, when the headquarters was eliminated, Fort Shafter became home to U.S. Army Support Command, Hawaii, and the U.S. Army Corps of Engineers, Pacific Ocean Division (relocated from Fort Armstrong, (Hawaii)). In 1979 the Army established U.S. Army Western Command, which was renamed U.S. Army, Pacific in 1990. In 1983 the Army conveyed to the State of Hawaii 750 acres (3 km²) of undeveloped land on the mauka end of post. Today Fort Shafter remains the focal point for command, control, and support of Army forces in the Asia-Pacific region.
