The name changed to Arsenal Credit Union in 1952, a tribute to what NGA's current campus, along the banks of the Mississippi River in south St. Louis, used to be known as the "St. Louis Arsenal" back in the country's Civil War days. During this time, the site had warehoused small arms, artillery, gun carriages, ammunition and gunpowder. Field of  membership.
