The primary mission of Fort Eustis, in Newport News, Virginia, is Army transportation training, engineering support, and research and development. The fort also supports operations including aviation and marine shipping activities. It is home to the U.S. Army Aviation Logistics School, Army Transportation Corps, the Army Training Support Center, and the Army Aviation Applied Technology Directorate. Fort Eustis personnel train and educate officers and enlisted soldiers in all modes of transportation, aviation maintenance, logistics, and deployment doctrine and research.
In 1918, the U.S. Army bought Mulberry Island and nearby land in the military build-up for World War I. The Army named the outpost Camp Abraham Eustis, after Brevet Brigadier General Abraham Eustis, a 19th-century U.S. military leader and first commanding officer of Fort Monroe. The U.S. military used the camp as a coast artillery replacement center for Fort Monroe and a balloon observation school. In 1923 the Army renamed the facility Fort Eustis and made it a permanent military installation.
Fort Eustis has been used in a number of ways, including as an Army training facility for artillery and artillery observation, a prison for prohibition law offenders, and a work camp for the Works Progress Administration.
In 2010, the United States military combined Fort Eustis with nearby Langley Air Force Base to form Joint Base Langley–Eustis. The Army Element of the post is under the command of the U.S. Army Training and Doctrine Command, as of 2015.
