At the end of 1947, "Mockingbird" returned to the Far East, joining MinRon 7 in early January 1948. For the next year and a half she operated in Japanese waters, primarily in the Inland Sea area and in the Straits of Shimonoseki June 1950 brought open hostilities to the Far East again as troops from North Korea streamed over the border separating it from the Republic of Korea, formerly an American occupation zone. From 14 to 16 July "Mockingbird" conducted a check sweep of Hoko Ko, Korea, with her squadron, in preparation for an amphibious landing at Pohang by the 1st Cavalry Division 18 July. After that mission, the squadron made a similar sweep at Chinhai and then returned to Japan.
