The Drummond class are 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, serve in the "Atlantic Area of Operations" of the Argentine Navy, based on Mar del Plata Naval Base, province of Buenos Aires. Their mission is to patrol Argentina's exclusive economic zone and to enforce fishing regulations, but according to reports in November 2012 they "hardly sail because of lack of resources for operational expenses". As of 2020 only Granville, which had been refitted in mid-2019, was reported operational, with the other ships of the class in reserve.
