Patiño is a replenishment oiler of the Spanish Navy. It was named after the Spanish navy minister José Patiño Rosales, who reorganized the fleet on the orders of Philip V of Spain. The vessel was ordered in 1991 from Navantia and built at their yard in Ferrol, Galicia. The ship entered service with the Spanish Navy in June 1995 and is homeported at Ferrol. Patiño has been deployed with NATO forces around the world, participating in missions in the Kosovo War, the War in Afghanistan along with the European Union's anti-piracy mission to Somalia.

Patiño is a product of cooperation between the Royal Netherlands Navy and the Spanish Navy. The design of the ship is similar to HNLMS Amsterdam of the Royal Netherlands Navy, the vessels were developed in cooperation.[1] The replenishment oiler was built to merchant ship standards. Patiño is 166 m (544 ft 7 in) long with a beam of 22 m (72 ft 2 in) and a draught of 8 m (26 ft 3 in). The ship has a full load displacement of 17,045 long tons (17,319 t) and is 5,762 long tons (5,854 t) light.[2]

Patiño is fitted with two Navantia / Burmeister & Wain 16V40/45 diesel engines driving a single shaft with a five-bladed controllable-pitch propeller. The engines are rated at 24,000 hp (17,897 kW). This gives the vessel a maximum speed of 20 knots (37 km/h; 23 mph) and a range of 13,450 nautical miles (24,909 km; 15,478 mi) at 20 knots.[2]

The replenishment oiler is fitted with three navigation-surface search and helicopter control radars operating at I-band.[2] The management of the ships communications is made through the Integrated Communications Control System (ICCS 3rd generation) from the Portuguese EID. The countermeasures equipment aboard Patiño include: four Mk 36 SRBOC (super rapid blooming offboard chaff), six-barrelled launchers from Lockheed Martin Sippican for infrared decoys and chaff, distraction and deflection of incoming anti-ship missiles to a range of 4 kilometres (2 nmi); an AN/SLQ-25A Nixie towed torpedo decoy system from Argon ST. The two towed units emit acoustic signals from an onboard transmitter. The vessel is also equipped with an Aldebaran Electronic Support Measures / Electronic Countermeasures (ESM / ECM) system from Spain's Indra Group.[1]

Armament and aircraft

Patiño's weapons system include two Oerlikon 20 mm/90 calibre guns and the vessel is fitted for two Izar FABA Systems Meroka 20 mm/120 calibre close-in weapon system (CIWS).[2][a] The guns have a rate of fire of 1,440 rounds per minute and range of up to 2,000 metres (2,187 yd). The Meroka CIWS includes an infrared camera and video auto-tracker.[1]

Patiño is designed to carry up to five helicopters. The vessel has a 490 m2 (5,300 sq ft) flight deck and a hangar on the stern of the ship. The replenishment oiler has a normal complement of only three Sikorsky SH-3 Sea Kings with 19 air crew provided.[1] However, the vessel can carry a maximum of two Sea Kings and three AB 212 helicopters at the same time.[2]


The replenishment oiler carries 6,815 long tons (6,924 t) of diesel fuel and has two supply stations, one on each side of the ship for liquids and solids. The ship is also capable of stern refuelling. Patiño carries 1,660 long tons (1,687 t) of aviation fuel and has a 500-long-ton (508 t) capacity for solid stores. The ship has one vertical replenishment supply station and has aircraft maintenance workshops. Patiño is equipped with medical facilities.[2]
