World War II Pacific Theater operations

First tour 1943-1944

Coos Bay cleared San Diego, California on 22 July 1943 for Pearl Harbor, Hawaii, Espiritu Santo, and Cavutu, where she established a seadrome for Patrol Squadron 71 (VP-71) from 13 October 1943 until 23 November 1943. She was based successively at Tulagi, at Blanche Harbor in the Treasury Islands, and at Green Island until 16 June 1944.

After carrying men and equipment of Fleet Air Wing 1 (FAW-1) from New Georgia to Espiritu Santo, Coos Bay sailed on 21 August 1944 for Guadalcanal, where she unloaded aviation equipment. From 8 September 1944 to 9 December 1944 she served at Saipan as station tender, then returned to San Pedro, California, for an overhaul.

Damaged in collision at sea

Coos Bay returned to Pearl Harbor on 17 March 1945. On 21 March 1945 she departed for Ulithi Atoll. During her passage, on 31 March 1945, she collided with an oceangoing tug - M/V Matagorda, which took her in tow for emergency repairs at Eniwetok. Coos Bay proceeded to San Pedro for repairs and overhaul. Returning to Pearl Harbor, Coos Bay remained there until 1 September 1945. Meanwhile, hostilities with Japan ended on 15 August 1945.
