Design and description

edit

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 3,600 brake horsepower (2,700 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 Bofors 40 mm gun, one 20 mm Oerlikon GAM-B01 cannon and two machine guns. The Azteca class has a complement of 24.[1][2]
