Following a restful holiday period, the submarine departed Oahu on 2 January 1945 and set a course for Saipan. There, on 15 January, she joined with Spadefish, Atule, and Pompon and sailed for a patrol area in the East China and Yellow Seas. Bad weather and a scarcity of targets denied Bang opportunities to attack any enemy shipping before she departed the area on 19 February, without any kills.
