The Azteca-class patrol vessel are a class of patrol vessels in service with the Mexican Navy. They were designed and built by the British companies T.T. Boat Designs Ltd; Ailsa Shipbuilding Co. Ltd., Scott & Sons, Bowling; Lamont & Co. Ltd. and Vera Cruz and Salina Cruz Shipyards for the Mexican Navy from 1976 to 1980. They are multi-role patrol craft with good nautical characteristics. Original units were powered by Paxman diesels of either 3,600 hp (2,700 kW) or 4,800 hp (3,600 kW). Original units were named with pre-Hispanic tribal names.

Design and description

The Azteca-class patrol vessels displace 148 long tons (150 t) at full load and are 111 feet 10 inches (34.1 m) long overall and 101 feet 4 inches (30.9 m) between perpendiculars. They have a beam of 28 feet 3 inches (8.6 m) and a draught of 6 feet 6 inches (2.0 m). The ships are propelled by two shafts driven by two Ruston Paxman Ventura diesels creating 36,000 brake horsepower (27,000 kW). This gives the vessels a maximum speed of 24 knots (44 km/h; 28 mph) and a range of 2,400 nautical miles (4,400 km; 2,800 mi) at 12 knots (22 km/h; 14 mph). The ships are armed with one 40 mm L70 Bofors DP gun, one 20 mm Oerlikon GAM-B01 cannon and two machine guns. The Azteca class has a complement of 24.[1]
