ATON Grp SAN FRANCISCO

The ATON Group San Francisco, short for Aids to Navigation Group San Francisco, is a United States Coast Guard unit responsible for maintaining and servicing navigational aids throughout the San Francisco Bay Area and surrounding Pacific coastline. Established to ensure maritime safety in one of the nation’s busiest and most challenging waterways, the unit’s history stretches back to the early 20th century when reliable navigation became critical to the region’s commercial and military operations. Over the decades, ATON Group San Francisco has played a vital role during wartime mobilizations, peacetime commerce, and disaster response, continually upgrading its capabilities to include modern electronic and physical navigation systems. Today, the unit’s dedicated crews maintain buoys, beacons, and lights, supporting safe passage for thousands of vessels annually and upholding the Coast Guard’s mission of maritime safety and security.
