USA SAN PABLO (AGS-30)

USS San Pablo (AGS-30) was originally built as the Liberty ship SS William G. Sumner in 1944 before being acquired and converted by the U.S. Navy into a survey ship in 1944. Commissioned as USS San Pablo (AGS-30) in March 1945, she was fitted with specialized equipment for hydrographic surveying and oceanographic research. During her service, San Pablo operated primarily in the Pacific, supporting post-World War II naval operations by conducting vital charting and mapping missions. She continued her service into the early Cold War period before being decommissioned in 1969 and subsequently struck from the Naval Vessel Register.
