The ship was incorporated into the Argentine Navy on 4 August 1947, and assigned the name ARA "Trinidad" (P-34) in memory of ARA "Santísima Trinidad", an Argentine Navy brigantine of 1815–1816 that saw action in the Argentine War of Independence. Commander (S) D. Rodolfo A. Muzzio initiated a campaign to assign the full name "Santísima Trinidad" to her, and she became ARA "Santísima Trinidad" (P-34) on 3 October 1950.
