The Naval Support Activity New Orleans spans both shores of the Mississippi River. The purpose of the facility is to support and meet the needs of military personnel, both in and out of battle. Today, the base plays home to the Naval Air Force Reserve, the Marine Forces Reserve, the 4th Marine Division, and the 4th Marine Aircraft Wing. There are around 3,900 active duty members stationed at Naval Support Activity New Orleans, and around 2,700 civilians who are personnel at the base.
NSA New Orleans was originally established in 1901, however, it has had long periods of inactivity. The station had a rebirth in 1939, and since then, the base has been used actively. The base started as a typical Naval station, but after 1966, the Army (who controlled the east bank of the Mississippi), transferred their land over to the Navy. After this point, the area became known as Naval Support Activity New Orleans. NSA New Orleans was actually proposed to be closed down in a 2005 BRAC document, but in the final report, the NSA was not listed, so it remains active today.
