There is little consensus regarding the origin of the name Belle Chasse. In French, belle chasse literally means "beautiful hunting." It is widely believed that it was so named due to the richness of wildlife which the initial French colonists observed when they settled in the region. Others say that Belle Chasse was named after a Colonel Joseph D. Bellechasse, who lived in New Orleans around the late 18th and early 19th century. Alternatively, it was named after the plantation of Deville de Goutin Bellechasse .
The Naval Air Station was founded in 1941 on the south shore of Lake Pontchartrain, but in 1957 it relocated to its current location. It has been designated as a Joint Forces Reserve Air Station. It is home to various naval air units as well as an Air Force Reserve fighter squadron and a Marine Corps Reserve helicopter unit. In March 2009, U.S. Navy Reserve Airborne Early Warning Squadron 77 (VAW-77) relocated its six E-2C aircraft from NAS Atlanta, GA to Belle Chasse. The squadron routinely deploys to the Caribbean on counter-narcotic operations. The squadron aircrew are all U.S. Naval Reservists while the maintenance department for the aircraft is run by Northrop Grumman Field Services.
