The USS Bowditch (AG-30) was a United States Navy survey vessel in commission from 1940 to 1947, playing a significant role during World War II in hydrographic and geodetic surveying operations. Originally constructed as a commercial passenger ship, she was launched in 1929 by Burmeister and Wain in Copenhagen, Denmark, as the MS Santa Inez for the Grace Line. This diesel-powered vessel featured a short funnel, a cruiser stern, and accommodated 125 passengers in two classes. She primarily served on Grace Line's secondary route from New York City to Valparaiso, Chile, until the Great Depression led to her being laid up in 1932. She resumed service in 1933 when Grace Line revived its secondary routes. The U.S. Navy purchased Santa Inez on 4 March 1940 and temporarily commissioned her as USS Bowditch (AG-30) on 12 March 1940. She was then decommissioned for fitting out as a survey ship at Norfolk Navy Yard, with her recommissioning occurring on 1 July 1940 under Commander E. E. Duval. Her early service involved extensive geodetic surveys in Newfoundland, Bermuda, the Bahamas, Jamaica, Cuba, and Haiti. With the escalation of World War II, Bowditch intensified her survey missions, including hydrographic work between Panama and Colombia, off the Galápagos, and Costa Rica's Cocos Islands. She returned to Norfolk for repairs in late 1942 and resumed operations in the Caribbean and later in the Pacific theater after transiting the Panama Canal. Reclassified as AGS-4 on 1 December 1943, she participated in critical invasion and occupation operations at Kwajalein, Saipan, and Okinawa, supporting amphibious assaults and rescuing survivors of US Navy vessels off Okinawa. Following the war's end in August 1945, Bowditch remained off Okinawa until November. She then returned to the United States, arriving in San Francisco in late 1945. In 1946, she conducted surveys at Bikini Atoll in preparation for Operation Crossroads, including post-atomic test surveys. She was ultimately decommissioned at Norfolk on 31 January 1947 and transferred to the Maritime Commission in 1948 for disposal. The USS Bowditch’s service exemplifies the crucial role of survey ships in wartime operations and post-war atomic testing reconnaissance.
