Her ports of call on this long voyage were Durban, South Africa; Bombay; Melbourne, Australia; and San Pedro, Los Angeles, where she arrived 1 July.

She sailed for Boston from California early in 1947 for conversion to a combination dependent and troop transport, emerging 28 June and returning to San Francisco.

Transferred to the Military Sea Transportation Service (MSTS) under Navy captain and crew in October 1949, she departed for Norfolk via the Panama Canal and Bermuda, arriving 10 January 1950.

General H. W. Butner arrived San Diego 24 April, and on 10 May made another Pacific cruise which lasted until her return to the West Coast 12 June.

This daring amphibious operation took the communist troops by surprise and forced them to abandon the ground they had taken in South Korea and to retreat north across the 38th Parallel.

In 1951 the ship continued to sail from California to Yokohama and Guam in support of the UN war effort in Korea until she left San Francisco for Galveston, Texas, 29 June.

General H. W. Butner began a regular schedule from Brooklyn, New York, to Southampton and Bremerhaven soon afterward, supporting American military commitments in Europe.

She was turned over to the Maritime Administration (MARAD), and in March 1960 entered the National Defense Reserve Fleet, berthed in the James River, Virginia.
