Returning from her Bermuda shakedown voyage on 17 October 1943, she was overtaken by a hurricane that almost capsized the vessel and caused a fire in the aft engine room.

The last round-trip voyage required 30 days to convoy heavy equipment, such as floating cranes and powerplants, being towed to Plymouth, England, for use in the captured ports on the continent.

Lee Fox arrived at Pearl Harbor on 31 May, having transited the Panama Canal on 13 May and spent three days at San Diego, California.

Continuing westward from Guam with a new list of passengers, Lee Fox next dropped anchor in San Pedro Bay, Philippines, on 6 July.

Following a period in dry dock, she arrived at Green Cove Springs, Florida, on 14 February 1946 and decommissioned there on 13 May and entered the Atlantic Reserve Fleet.
