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 currently 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”.[2]

Design

Although its designers consider the A69 D'Estienne d'Orves class to be avisos, Argentina classifies the ships as corvettes.

The Drummond-class ships are equipped mostly with German and Dutch electronic systems (instead of French)[3] for better compatibility with the two MEKO classes in Argentine service, and integrated with the indigenous "Miniaco" combat system.

History

The first two ships of the class were built in 1977 in France for the South African Navy. The sale was embargoed by United Nations Security Council Resolution 418 during sea trials and the ships bought by Argentina instead on 25 September 1978.[1] A third ship was ordered and entered service as ARA Granville on 22 June 1981,[1] in time for the Falklands War the following year. There are minor differences in equipment fit compared to her sisters, for instance Granville has French Degaie decoys rather than the British Corvus chaff launchers.[1]

On 28 March 1982 Granville and Drummond sailed from Argentina and took up station northeast of Port Stanley to cover the main amphibious landings on 2 April.[4] Meanwhile, Guerrico covered the assault on South Georgia, sustaining significant damage from the Royal Marines in the process. After repairs she joined her sister ships north of the Falklands as Task Group 79.4, hoping to catch ships detached from the British task force.[5] On 29 April the corvettes were trailed by the submarine HMS Splendid whilst she was looking for the Argentine aircraft carrier ARA Veinticinco de Mayo, but they managed to outrun the British submarine.[6]

The Drummond class carried pennant numbers P-1 to P-3 until the introduction of the Espora-class corvettes in 1985 when they became P-31 to P-33. In 1994, they participated in Operation Uphold Democracy, the United Nations blockade of Haiti. During this time, they were based at Roosevelt Roads Naval Station in Puerto Rico.[7]
