The Drummond class were three corvettes designed and built in France based on the A69 D'Estienne d'Orves-class avisos. The ships were commissioned in the Argentine Navy between 1978 and 1982.

The ships, when operational, served in the "Atlantic Area of Operations" of the Argentine Navy, based on Mar del Plata Naval Base, province of Buenos Aires. Their mission was to patrol Argentina's exclusive economic zone and to enforce fishing regulations,^[2]^[3] but according to reports in November 2012 they "hardly sail[ed] because of lack of resources for operational expenses".^[4] As of 2020 only Granville, which had been refitted in mid-2019, was reported operational, with the other ships of the class in reserve.^[5] In 2024, Granville was retired while the other two vessels of the class were put up for auction.^[6]
