Near the end of World War II, thousands of new jobs were created with the 1944 construction of a naval ammunition depot across the Ouachita at Shumaker. The Korean War generated new jobs and activity at the depot, which closed after war's end. The city and county redeveloped its facilities and grounds into an extensive industrial area. This was the site of some major defense establishments and multiple smaller industries. A technical campus of Southern Arkansas University is also located there.
