The Centauro-class patrol boat is a series of four patrol boats in service with the Portuguese Navy. It is an evolution of the preceding Script error: The function "sclass" does not exist.. This class is meant for fisheries inspection and control duties mainly in the Mainland Portugal shores – with some sporadic presence in the Madeira Archipelago. The Centauro class is Portuguese-designed and built at the Arsenal do Alfeite (Almada) and Estaleiros Navais do Mondego (Figueira da Foz).

Design and description

The Centauro-class patrol boats are an evolution of the Script error: The function "sclass" does not exist., constructed of aluminium instead of the Argos' glass reinforced plastic design. The Centauro class measure 28.4 metres (93 ft 2 in) long with a beam of 5.95 m (19 ft 6 in) and a draught of 1.45 m (4 ft 9 in).[1][2][lower-alpha 1] The patrol boats have a standard displacement of 82 tonnes (81 long tons) and 94 t (93 long tons) fully loaded.[2][3][lower-alpha 2] The vessels are powered by two Cummins KTA-50-M2 diesel engines turning two shafts creating 2,700 kilowatts (3,600 hp). This gives the vessels a maximum speed of 26 knots (48 km/h; 30 mph), though they did make 28 knots (52 km/h; 32 mph) during sea trials.[2] They have a range of 1,350 nautical miles (2,500 km; 1,550 mi) at 15 knots (28 km/h; 17 mph)[3] or 640 nmi (1,190 km; 740 mi) at 20 knots (37 km/h; 23 mph).[1][2] The Centauros are equipped with two Cummins 6BT5.95(M) diesel generators producing 150 kW of electricity. The ships can operate in sea state 3.[1]

The patrol boats mount a single Oerlikon 20-millimetre (0.79 in)/70 Mk 4 gun for anti-air defence.[2] The ships were equipped with navigational radar only.[2][3] They also carry a 4 m (13 ft) launch carried on a launch-and-recovery ramp on the stern and the boat can be recovered at speeds up to 10 knots (19 km/h; 12 mph).[1][2] The vessels have a complement of eight, including one officer.[1][3][lower-alpha 3]

Construction and career

The class were ordered in 1998 as an improved version of the Argos class.[2] They were designed and built in Portugal.[4] Upon entering service, the vessels were deployed for fisheries protection, search and rescue and general patrol. The Centauros take part in some naval exercises and some training.[3] In 2006, one boat of this class, NRP Sagitário, became the first Portuguese warship with a female commander, the second lieutenant Gisela Antunes.[5][6]
