Truxtun departed Charleston on 24 July 1945 for shakedown training in the vicinity of Guantanamo Bay, Cuba, until 25 August 1945, ten days after the end of World War II.

On 10 September 1945, she cleared Hampton Roads, Virginia, for a two-week, round-trip voyage to Miami, Florida.

She spent the remainder of her U.S. Navy career in reserve at Green Cove Springs until 1961, then at Orange, Texas.

The ship served in the Republic of China Navy as the frigate ROCS Fu Shan (PF-35) and received a second 5" gun aft as well as (in 1983) a Sea Chaparral surface-to-air missile launcher in place of her landing craft davits.

Fu Shan had most of her armaments removed for other uses by 1988 and was reverted to a fast transport (LPR-835; her landing craft davits were also reinstated) in 1996.
