"Agerholm" was assigned to Destroyer Division (DesDiv) 12 and settled into a routine of local training operations in the waters off southern California. On 10 March, the warship sailed from San Diego on her first extended cruise to the western Pacific. While operating with the 7th Fleet, "Agerholm" visited the Chinese ports of Tsingtao, Shanghai, and Amoy, before they were closed to American traffic. She also visited Kwajalein, Okinawa, Hong Kong, and several ports in Japan. The destroyer returned to San Diego on 26 November and remained there for the holiday season.
