World War II
Departing California on 16 June 1945, Pine Island steamed to Okinawa. There she tended seaplanes engaged in air-sea rescue operations during the final phases of World War II. At the end of the war, she entered Tokyo Bay and contributed seaplane flight operations to the occupation of Japan in 1945. Following occupation duty in Japan, she conducted seaplane flight operations in the Whangpoo River near Shanghai, China. She left the Pacific in 1946, and steamed via the Suez Canal to Norfolk, Virginia.
