Dictionary of American Naval Fighting Ships: The second Dynamic (AM 432) was launched 17 December 1952 by Colberg Boat Works, Stockton, Calif.; sponsored by Mrs. R. W. Harbey; and commissioned 15 December 1953, Lieutenant Commander J. F. Butler in command. She was reclassified MS0-432 on 7 February 1955.

Assigned to Mine Division 91, Squadron 9, Mine Force Pacific Fleet, Dynamic operated out of her home port of Long Beach, Calif., that included training with other ships, aircraft, soldiers and Marines and with minesweepers of other navies. She cruised to the Far East in 1957-58 visiting ports in Japan, Korea, and Taiwan, and participated in minesweeping exercises with ships of the Chinese Nationalist and Korean navies. She made a similar cruise in the first half of 1960, joined the other fleet units in the "Pacific Festival" at San Francisco in September and received a yard overhaul during the remainder of the year.
