The Allende class is the name of anti-submarine frigates used by the Mexican Navy. Allende-class frigates are former United States Navy Template:Sclass-, and they were bought in 1997. They form the Mexican Gulf Fleet of the Mexican Navy. They are used for anti-submarine and offshore patrol duties. This is because weapons are reduced to only one 5-inch (127 mm)/54 caliber Mk 42 DP gun and four fixed ASW torpedo launchers. Electronic combat systems are also reduced and consist only of one gun fire control system. Western Electric SPG-53F and one MK 114 ASW fire control system for ASW torpedos of 324 mm. All hulls have ASROC Mk 16 octuble launcher system. Allende-class frigates can operate one small on-board helicopter (MBB Bo 105).
