National Geospatial-Intelligence Agency (NGA)

For two centuries, the St Louis Arsenal played a key role in American history. From the Westward Expansion, to the Civil War, continuing through two world wars, the NGA property has a long, rich history and now serves as a western base of operations for NGA.

In 1943, the Aeronautical Chart Plant was established in St. Louis for mapping services. In 1972, budgeting concerns prompted the armed services to combine their mapping and charting abilities into a centralized agency called the Defense Mapping Agency. In 1996, the U.S. Congress, the Central Intelligence Agency and the U.S. Department of Defense created the National Imagery and Mapping Agency (NIMA) and combined imagery intelligence with map-based imagery.

On Nov. 24, 2003, President George W. Bush signed the 2004 Defense Authorization Bill, which authorized NIMA to change its name to the National Geospatial-Intelligence Agency. NGA currently serves military, civil and international geospatial intelligence needs and supports national security.

Current Events at NGA

Scott Air Force Base is conducting ongoing environmental site investigations at the current NGA site to address past releases due to the use of photo-processing chemicals. A proposed plan to address contamination at the site was available to the public for comment from Nov. 30, 2018 to Jan. 18, 2019. The next step is to review and consider public comments before finalizing the cleanup decision.
