Sailing north on the 14th, "Berkeley" embarked American and Japanese midshipmen at Yokosuka and Kure for two weeks of training with units of the Japanese Maritime Self-Defense Force in the Inland Sea. Returning to Subic Bay on 7 August, the warship spent the next 10 weeks operating locally with "Constellation". Then, in response to the growing Soviet Navy presence in the Indian Ocean, several American warships—including "Berkeley"—received orders to "show the flag" in the region. Departing Subic Bay on 27 October, she conducted a four-day port visit to Singapore, before getting underway for the Indian Ocean on 8 November.
