The USS Jamestown (PG-55) was a versatile patrol gunboat and later a Jamestown-class motor torpedo boat tender, constructed in 1928 by Pusey & Jones Corp. in Wilmington, Delaware. Originally named Savarona, she was renowned as the largest and most luxurious yacht of her time, owned by Mrs. Thomas S. Cadwallader. In 1929, Colonel William Boyce Thompson purchased her and renamed her Alder. The vessel was subsequently donated to the U.S. Navy in December 1940, transformed into a gunboat at Bethlehem Shipbuilding Co. in Hoboken, New Jersey, and commissioned as USS Jamestown (PG-55) in May 1941. Initially, Jamestown’s service involved training U.S. Naval Academy midshipmen, conducting cruises from Annapolis to Norfolk. After her conversion to a motor torpedo boat tender, she played a crucial role in establishing the Motor Torpedo Boat Training Center at Melville, Rhode Island, serving as a training ship and tender for Squadron 4. In August 1942, Jamestown set sail for the South Pacific, arriving amidst the Guadalcanal campaign. She supported the US Marines and PT boats by escorting resupply convoys, towing barges with fuel and bombs, and maintaining vital supply lines through enemy-infested waters. Stationed at Tulagi and Espiritu Santo, she serviced PT boats operating in “Iron Bottom Sound,” frequently challenging Japanese naval forces. Her efforts earned her and Squadron 3 a Presidential Unit Citation for their role in the Guadalcanal campaign. Redesignated AGP-3 in January 1943, Jamestown continued her support operations, shuttling supplies between island bases, and escorting vessels through combat zones. After a stint of overhaul in California in 1944, she transitioned to supporting Allied operations in New Guinea and the Philippines, maintaining communications and logistics for PT boats and troop movements. Decommissioned in March 1946 after the war, Jamestown’s service was marked by her adaptability and vital support in key Pacific campaigns, exemplifying the logistical backbone essential to U.S. naval operations during World War II.
