Numancia (F83) is the third of the six Spanish-built Template:Sclasss of the Spanish Navy, based on the American Template:Sclass design. The frigate was constructed in Spain by Bazan and laid down on 8 January 1986; launched on 29 January 1987; and entered service with the Spanish Navy on 17 November 1989. Based at Rota, Numancia has been deployed to the Indian Ocean to fight piracy in Somalia as part of Operation Atalanta and to the Mediterranean Sea to intercept illegal trafficking of migrants as part of Operation Sophia.

Design and description

The Santa María class is a series of six guided missile frigates based on the American Template:Sclass.Template:Sfn The Oliver Hazard Perry class had been conceived as a way to reduce unit costs while maintaining an anti-air warfare (AAW) platform with anti-submarine (ASW) and anti-surface warfare capabilities.Template:Sfn The Oliver Hazard Perry class came in two forms: short-hulled and long-hulled, with the Santa María class being the later, with an additional beam to allow for more top weight for future modifications.Template:Sfn The class came in two batches, with the first four being from batch one and the final two from batch two. The first batch of ships had a displacement of Template:Convert light, Template:Cvt standard, and Template:Cvt at full load. The second batch has the same light and standard displacements, with a full load displacement of Template:Cvt. The frigates measure Template:Convert long overall and Template:Cvt at the waterline with a beam of Template:Cvt and a standard draught of Template:Cvt and a maximum draught at the sonar dome of Template:Cvt.Template:Sfn The ships have a complement of 223 sailors including 13 officers.Template:Sfn

The Santa María class is propelled by a controllable pitch propller powered by two General Electric LM2500 gas turbines creating Template:Convert, giving the vessels a maximum speed of Template:Convert. The frigates stow Template:Cvt of fuel and have a range of Template:Convert at Template:ConvertTemplate:Sfn or Template:Cvt at Template:Convert.Template:Sfn The ships have four 1,000 kW Kato-Allison 114-DOOL diesel generator sets creating a total of 4,000 kW. These can power two Template:Cvt retractable, rotatable auxiliary propulsion motors.Template:Sfn The vessels have fin stabilisers fitted.Template:Sfn

Armament and sensors

Frigates of the Santa María class are armed with a single-armed Mk 13 missile launcher serviced by a 40-round magazine that can handle 32 SM-1MR anti-air/ship missiles and 8 Harpoon anti-ship missiles. The Harpoon missiles have a range of Template:Cvt at Mach 0.9 carrying a Template:Convert warhead. The SM-1R missiles have a range of Template:Cvt at Mach 2. The vessels also mount a single [[Otobreda 76 mm|OTO Melara Template:Convert/62 calibre naval gun]] capable of firing 85 rounds per minute up to Template:Cvt with each shell carrying a Template:Cvt warhead.Template:SfnTemplate:Efn For AAW defence, the ships mount a single Meroka Template:Cvt/120 12-barrelled close-in weapons system (CIWS) capable of firing 3,600 rounds per minute up to Template:Cvt. For ASW, the frigates are armed with two triple-mounted Mark 32 torpedo tubes for Mod 5 Mark 46 torpedoes.Template:Sfn

The vessels are equipped with AN/SPS-49(V)4 2-D air search radar, RAN-12L (being replaced by RAN-30) 2-D low horizon air search radar for the Meroka CIWS, SPS-55 surface search radar and a Mk 92 fire-control radar. For ASW, the ships have SQS-56 sonar and SQR-19(V) towed arrays. For weapons fire control, they have Mk 13 weapons control, Mk 92 and SPG-60 STIR missile control, and SQQ-89 ASW systems. For electronic warfare they have a Nettunel intercept, a SLQ-25 Nixie towed torpedo decoy, and Mk36 SROC decoy launchers.Template:Sfn

Aircraft

As long-hulled versions of the Oliver Hazard Perry class, the Santa María-class frigates have twin hangars to accommodate up to two Sikorsky SH-60B Seahawk Light Airborne Multi-Purpose System (LAMPS) III helicopters though only one is usually embarked. The helicopter deck, located aft, is equipped with the RAST helicopter deck-handling system designed to handle LAMPS helicopters.Template:Sfn

Construction and career

The frigate was ordered on 29 June 1977. The ship was laid down on 8 January 1986, at Izar's shipyard in Ferrol, Spain.Template:Sfn Delays in construction followed as the Spanish Navy deferred the frigate's construction in order to focus on the construction of a new aircraft carrier.Template:Sfn Numancia was launched on 29 January 1987, and commissioned into service on 17 November 1989.Template:Sfn The vessel is homeported at Rota, Spain, as part of the 41st Escort Squadron.Template:Sfn

On 27 April 2009, Numancia seized the nine Somali pirates that tried to board the cruise ship after a short chase. From March to August 2013, Numancia deployed to the Indian Ocean as part of Operation Atalanta. In 2016, the frigate was deployed as part of Operation Sophia, intercepting the illegal trafficking of migrants in the Mediterranean Sea. In 2022, Numancia returned to the Indian Ocean, escorting food relief ships through the area as part of Operation Atalanta.
