Back in Pearl Harbor from 12 July 1944 to 12 August, Fremont sailed then for rehearsal landings in the Solomons, and on 8 September she sortied for the Palau Islands operation.

She came under enemy air attack on several occasions, and on 24 October, during the decisive Battle for Leyte Gulf, a small caliber shell which exploded on her bridge injured seven men.

Two voyages to Pearl Harbor, and two more to Pacific islands and the Philippines to bring servicemen eligible for immediate discharge home kept Fremont at sea between 9 October 1945 and 12 August 1946.

In the years from 1947 through 1960, Fremont completed seven tours of duty with the 6th Fleet in the Mediterranean, participating in amphibious exercises with marines and ships of other NATO navies.

The Lebanon Crisis broke out during her 1958 tour of duty, and she joined in landing Marines at Beirut 17 July to 6 August, returning to reembark troops in September.
