Between 11 February and 29 June 1944 Liddle escorted convoys on three round trips across the North Atlantic from New York City to Wales, Gibraltar, and Tunisia.

She then transported Australian troops to the Netherlands East Indies, and supported the landings at Brunei Bay on 10 June and Balikpapan on 1 July.

Departing Green Cove Springs on 25 November, she arrived Norfolk, Virginia, two days later to join Transport Division 22.

The need in Korea for troops with amphibious experience brought the ship to Boston in January 1953, to the Caribbean the next month, and returned her to Little Creek operations for the remainder of the summer.

Departing Oran, Algeria, on 23 January 1954, Liddle returned to Little Creek on 4 February where she became an ASW schoolship, engaged in more amphibious exercises, and conducted midshipman cruises.

As a unit of the Atlantic Amphibious Force, the ship resumed training which included a demonstration landing for President Kennedy off Onslow Beach, North Carolina, on 14 April 1962.

Operating between Little Creek and the Caribbean, Liddle participated in a mercy mission to Haiti from 13 to 19 October 1963 to deliver food, clothing, and medical supplies to the coastal areas struck by Hurricane Flora.

From 1964 through 1966 her continuing service along the Atlantic coast and in the Caribbean represented the constant effort of the Navy to maintain a high degree of training and efficiency in case of a national emergency.
