notes"The Almirante Brown class is a warship built in Germany for the Argentine Navy. They were commissioned between 1983 and 1984, after the Falklands War. The class comprises four ships; Almirante Brown, La Argentina, Heroína and Sarandí. They are classified as either frigates or destroyers by different publications. The MEKO 360 type warships are based on modular designs which allow quick changes to the vessel's armaments depending on mission requirements. The modular nature of the construction also allows the ships to be modernized or refitted with greater ease. Six vessels were initially ordered, however two ships were cancelled and replaced with orders for MEKO 140 type hulls. Ordered in 1979, construction of the ships was delayed as the British turbines were embargoed after the Falklands War. Furthermore, the acquisition of helicopters for the vessels has seen many incarnations. They were initially intended to be equipped with Westland Lynx helicopters, but the order was cancelled in 1982. The planned replacement Agusta-Bell AB 212 helicopters were not funded and instead, all of the Almirante Brown class deploy with AS 555 Fennec, while only La Argentina and Sarandí can employ SH-3D Sea King helicopters. Almirante Brown took part in Gulf War operations in 1990. All of the ships can be used as flagships. Six vessels were ordered and four vessels of a second variant, MEKO 360H2, were constructed for Argentina. They were locally named the Almirante Brown class. They are considered frigates and destroyers by different publications. 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. Each ship is capable of being used as a flagship. The ships have a standard displacement of 2,900 long tons (2,900 t) and 3,360 long tons (3,410 t) at full load. The vessels are 125.9 metres (413 ft 1 in) long overall and 119.0 metres (390 ft 5 in) between perpendiculars with a beam of 15 metres (49 ft 3 in) and a draught of 5.8 metres (19 ft 0 in). The vessels are powered by a COGOG system driving two shafts composed of two Olympus TM 3B gas turbines rated at 51,800 shaft horsepower (38,600 kW) and two Tyne RM-IC gas turbines rated at 10,200 shaft horsepower (7,600 kW). The ships have a maximum speed of 30.5 knots (56.5 km/h; 35.1 mph) while using their Olympus gas turbines at 18 knots (33 km/h; 21 mph) using their Tyne turbines. The MEKOs have a maximum range of 4,500 nautical miles (8,300 km; 5,200 mi) at 18 knots. The Argentinian vessels are armed with eight Exocet surface-to-surface missiles in two quad launchers mounted centrally and one octuple launcher for Aspide surface-to-air missiles mounted aft of the superstructure. The MEKO 360H2 are also equipped with one OTO Melara 5-inch (127 mm)/54 calibre naval gun forward of the superstructure, eight Bofors 40 mm/70 calibre guns, and two triple-mounted 324 mm (13 in) ILAS torpedo tubes. The ships are equipped with a Graseby G1738 towed decoy countermeasure system, two Breda 105 mm (4 in) 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."
