The class comprised four ships; Almirante Brown, La Argentina, Heroína and Sarandí.

The MEKO 360 type warships are based on modular designs which allow quick changes to the vessel's armaments depending on mission requirements.

Ordered in 1979, construction of the ships was delayed as the British turbines were embargoed after the Falklands War.

The design is based on the concept of modular systems and is capable of changing the armament of the ship swiftly and can be modernized/refitted with more ease.

They have Decca 1226 navigational radar operating on the I band and their fire control systems are controlled by the Signaal SEWACO Link 10/11 system supported by Signaal STIR radar operating on the I/J and K bands, Signaal WM25 operating on I and J band, along with LIRODA radar systems that control the 40 mm gun mounts.

The class was intended for anti-submarine warfare (ASW) and an initial order for Westland Lynx helicopters was made to complement the ships.

[3] In 2006, La Argentina completed a two-year refit which included extensions to the flight deck to accommodate the Sea King helicopters.

The Almirante Brown class were reported to be short of spares and suffering engine problems.

[5] As of 2020, work was reportedly underway to maintain the operational relevance of both the aging Exocet and Aspide systems.
