In 1941, Letterkenny was chosen by the U.S Department of War to be one of twelve new ordnance depots. On December 18, 1941, the secretary of war  issued the directive to acquire 21,000 acres (85 km²) at Letterkenny for a depot. Letterkenny’s mission would be to reduce the surplus of forthcoming material and to store and ship ammunition, trucks, parts, and other supplies.

December 18, 1941 went down in history for Franklin County, Pa. by becoming the future landmark of Soldier support and dedication for generations to come. It was on that date, only 11 days after the bombing of Pearl Harbor, the Secretary of War issued a directive to acquire the site of Letterkenny Ordnance Depot, which would later become known as Letterkenny Army Depot (LEAD)/

The first shipment of ammunition arrived by train on September 23, 1942. More than 3 million tons of supplies were moved during World War II, Letterkenny was one of the largest depots of its kind and was called the Springboard of Invasion in 1944. Letterkenny became a permanent military installation on July 1, 1954. The ordnance depot was renamed Letterkenny Army Depot in August 1962, and command and control of the depot fell under the U.S Army material command. In the 1960s, with the war of Vietnam, Letterkenny’s missions increased.
