Prior to its construction, the Convention Hall located on 5th Street NW, between K and L had been used as an armory.[5] Construction on the new armory began on June 2, 1940, and it opened on July 13, 1941.[6] The structure was designed by the city's Municipal Architect, Nathan C. Wyeth.[7][8] The D.C. Armory replaced the National Armory, a 1910 structure which was designed by New York City architect Electus D. Litchfield.[9][10]
OPLAN 1954, a 1954 war game preparing for an atomic bomb exploding over Washington, D.C., supposed that a vacant parking lot near the Armory could be turned into an emergency airstrip for delivering medical supplies.[11] Initially, nonmilitary use of the Armory was facilitated by the D.C. Armory Board, which was formed in 1948.[3] During its existence the board oversaw the use of both the Armory and RFK Stadium.[3] In 1994 the board was dissolved and the city's use of the Armory came under the authority of the D.C. Sports and Entertainment Commission (DCSEC), which later became the Washington Convention and Sports Authority.[3][12]
The Armory's Drill Field is approximately 80,000 square feet (7,400 m2)[3] and has hosted trade shows, concerts, warehouse sales,[14] the Washington Auto Show,[15] sporting events, and Presidential inauguration balls.[3]
