Two days later, the carrier got underway for Alameda with 41 aircraft that needed repairs. She arrived on 13 July and, after offloading the aircraft, proceeded to Terminal Island for a three-week yard period. Between 11 August and 13 September, the escort carrier delivered spare parts, replacement aircraft, and personnel to Hawaii and the Marshalls. From September 1944 through mid-April 1945, "Thetis Bay" made five round-trip voyages from California ports to bases in the Pacific ranging from Pearl Harbor to Finschhaven, New Guinea.
