On 26 April, "Agerholm" set sail in company with the destroyer escort for the western Pacific. She arrived off the coast of Vietnam at "Yankee Station" on 28 May to serve as plane guard for Constellation. The destroyer then underwent a two-week availability alongside the auxiliary vessel in Sasebo, Japan commencing 8 June. Upon completion of those repairs, she put to sea for radar picket duty in the Gulf of Tonkin. Another two weeks at "Yankee Station" followed by two weeks on PIRAZ station brought her Vietnam service to an end. On 30 August, "Agerholm" departed the Gulf of Tonkin en route to MacKay, Australia, for liberty.
