During the late 1960s, Fort Hood trained and deployed a number of units and individuals for duty in [[Vietnam War|Vietnam]]. As the United States ended its role in the conflict, thousands of returning soldiers completed their active duty with one of the divisions. During this time, the post was modernized. On 13 September 1965, Darnall Hospital opened. In 1970, construction began on Palmer Theater and Venable Village was dedicated. Modern barracks were springing up around post. The wood buildings of the post were replaced with brick structures.{{citation needed|date=October 2015}}

In October 1969, Killeen Base was designated as [[West Fort Hood]] and the airfield's name was designated as Robert Gray Army Airfield. The base was named after a Killeen native who was a pilot of a B-25 bomber on the famous [[Doolittle Raid]] in Tokyo in 1942. He was killed later in World War II flying combat missions. With the redesignation came a change in mission at West Fort Hood. Nuclear weapons were removed; they had been secretly kept there since 1947.<ref>Fort Hood: The Great Place to Call Home, Fort Hood's Official Post Guide, Fort Hood History, page 72.
