DESCRIPTION

These German-built ships are officially classified as destroyers by the Argentine navy. The original order, dated Dec. 11, 1978, was for a class of six ships, but this was reduced to four ships when six units of the smaller MEKO 140 design were ordered (see ESPORA class database entry). As with all MEKO ships, this class has modular weapons and electronics for ease of modernization and repair.

HULL: These are flush-deck ships with the hull sides fared into the forward and after ends of the extensive, built-up superstructure. The superstructure and hull are made of steel, with sloping angles for a low radar signature. The hull is subdivided into 10 watertight compartments for increased survivability in case of a hit.

ARMAMENT: The two quad Exocet surface-to-surface missile launchers are forward of the twin stacks, while the Albatros octuple launcher is farther aft, abaft the air/surface search and the STIR radars. Two 40-mm twin gun mounts are located side-by-side in front of the bridge and abaft the 127-mm gun; two more are located outboard of the LIROD optronic director. The torpedo tubes are at the 01 deck level on either side of the stacks.

The ships were originally to have each embarked a Lynx helicopter, but the order for four Lynx helicopters was cancelled by Britain because of the Falklands War in 1982. A single AS 355 M Fennec is normally embarked, though two can be carried. Up to 10 anti-submarine warfare torpedoes can be carried for the helicopters. The helicopter is also equipped to provide over-the-horizon targeting for the Exocet missiles.

The vessels can carry a total of 10,752 rounds of ammunition.

SENSORS/ELECTRONICS: The class is equipped with a SEWACO combat data system.

MODERNIZATION: ALMIRANTE BROWN completed a two-year refit in 2005. LA ARGENTINA completed a similar refit in 2006 and SARANDI in 2009. Upgrades included reconfiguration of the flight deck to facilitate Sea King helicopter operations. EROINA completed a refit in 2008, but did not receive the flight deck modifications.
