After completing these duties, Pruitt spent most of the 1920s operating in the United States Asiatic Fleet in the western Pacific Ocean, protecting American interests in the East Asia.[1][2] Her pattern of operations was to spend winters in the Philippine Islands and summers along the coast of China,[2] including service on the Yangtze Patrol in October 1926, from March to June 1927, and in August 1927.[3]
In 1935 Lieutenant (junior grade)Richard O'Kane, who later would be awarded the Medal of Honor as the most successful U.S. submarine officer of World War II, reported for duty aboard Pruitt. Pruitt was converted to a light minelayer and accordingly redesignated DM-22 on 30 June 1937. O'Kane served aboard Pruitt until her minelayer conversion was complete.[2][4]
World War II
A unit of Mine Division 1, Pruitt was undergoing overhaul at the Pearl Harbor Navy Yard at Pearl Harbor, Hawaii, on 7 December 1941, with George Stephen Morrison, a future rear admiral, on board when the Japanese attack on Pearl Harbor brought the United States into World War II. At 07:53, Japanese planes flew over the base at low altitude and within minutes some of Pruitt's crew had sprinted to other ships and fired their first bullets. Others manned fire hoses and helped distribute ammunition during the attack. At the end of January 1942, Pruitt completed overhaul and took up offshore patrol and minelaying duties with the Hawaiian Sea Frontier until June 1942. On 19 June 1942, she departed Hawaii for Bremerton, Washington, from which she steamed to the Aleutian Islands for minelaying operations and escort assignments from a base at Kodiak, Alaska. Into the fall of 1942, she continued operations in the Aleutians, interrupted by regular runs back to the Hawaiian Islands. She then took up escort duties along the United States West Coast.[1]
On 6 June 1943, Pruitt returned to San Francisco and resumed coastal escort duties along the U.S. West Coast. Through the summer of 1943 she steamed along the coast of North America from Alaska to Southern California.[1]
Pruitt returned to San Francisco on 18 July 1944, underwent overhaul, and in October 1944 steamed to Pearl Harbor, where she began submarine training operations. Detached toward the end of November 1944, she patrolled off Midway Atoll in the Northwestern Hawaiian Islands from 29 November 1944 to 15 January 1945. On 22 January 1945 she resumed operations with the Training Command, Submarine Force, and for the remainder of World War II trained submarines southwest of Oahu. She was reclassified as a "miscellaneous auxiliary" and redesignated AG–101 on 5 June 1945.[1]
Pruitt received the Yangtze Service Medal for operations on the Yangtze Patrol from 20 to 28 October 1926, from 2 March to 2 June 1927, from 27 to 28 June 1927, and from 12 to 15 August 1927.[3]
