ADG worked with The Oklahoma Centennial Commission on a new museum that showcases artillery’s contributions to military heritage. The new space unites the collections of the Air Defense Artillery Museum and Ft. Sill Museum’s artillery holdings. The project united two existing warehouse buildings with the addition of a larger exhibition space. The new museum is just west of Key Gate and across the street from the historic Post Corral. The museum includes a large entry gallery and two gallery wings. The south gallery houses cannons, uniforms, saddles and other military equipment dating from the American Revolution of the First World War. The North Gallery houses larger ammunition including the modern M777 Howitzer, a restored tank that served in World War II, and early field computers from the Korean War.
