After training, she embarked soldiers, and sailed from Honolulu 22 January 1944 for Kwajalein, where she landed her troops on 1 February, one day after the initial assault.

Fayette sent her boats away with assault troops 21 July, then received casualties from the shore for 4 days, returning with them to Espiritu Santo 5 August.

Returning to Manus and Aitape to replenish, reload troops, and rehearse landings, Fayette sailed from New Guinea 28 December for Lingayen Gulf.

The task force in which she sailed met a variety of resistance from the Japanese, and Fayette joined in the general barrage which drove a dive-bomber off before it could strike a nearby battleship on the morning of the landings, 9 January 1945.

Fayette voyaged to the Far East between 28 August 1945 and 13 November 1945, carrying out occupation troops, and returning with servicemen eligible for discharge.
