superstructure. The MEKO 360H2 are also equipped with one OTO Melara /54 calibre naval gun forward of the superstructure, eight Bofors 40 mm/70 calibre guns, and two triple-mounted ILAS torpedo tubes. The ships are equipped with a Graseby G1738 towed decoy countermeasure system, two Breda SCLAR chaff rocket launchers with each launcher sporting 20 tubes. For electronic support measures, the vessels are armed with the Sphinx system and the Scimitar system for electronic countermeasures. The class is equipped with two Signaal DA08A air/surface search radar operating on the F band and Signaal ZW06 surface search radar operating on I band. 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. For sub-surface search, the vessels have Atlas Elektronik 80 hull-mounted active search sonar. All of the Almirante Brown class are equipped with a helicopter deck and hangar. They all deploy with AS 555 Fennec helicopters, while only La Argentina and Sarandí can employ SH-3D Sea King helicopters. The ships have a complement of 200, including 26 officers. Ships Construction and career Initially, six vessels were ordered, but this was later reduced to four after an order for six MEKO 140 type ships was placed. All four vessels were constructed at the Blohm+Voss shipyard in Hamburg, Germany. However, construction was delayed during the Falklands War as the British-built gas turbines were placed under embargo. The class was intended for anti-submarine warfare (ASW) and an initial order for Westland Lynx helicopters was made to complement the ships. The order was cancelled in 1982 and a planned replacement, the Agusta-Bell AB 212 helicopters, was not financed. Until the delivery of the AS 555 Fennec helicopters in 1996, the Argentinian Navy used Aérospatiale Alouette SA 319 helicopters aboard the ships. The first ship, Almirante Brown entered service in 1983 and the fourth and last, Sarandí in 1984. Almirante Brown took part in Gulf War operations in the Persian Gulf in 1990. In 2006, La Argentina completed a two-year refit which included extensions to the flight deck to accommodate the Sea King helicopters. Sarandí underwent a similar refit in 2008–2010. The four vessels form the 2nd Destroyer Squadron,
