The Santa María class are a series of six guided missile frigates based on the American .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, the short-hulled and long-hulled, with the Santa María class being of the later with additional beam to allow for more top weight for future modifications.Template:Sfn The class came in two batches, with the first four being of batch one and the final two of the second. The first batch of ships have a displacement of light, Template:Cvt standard and Template:Cvt at full load. The second batch have the same light and standard displacements, with a full load displacement of Template:Cvt. The frigates measure 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 propeller powered by two General Electric LM2500 gas turbines creating , giving the vessels a maximum speed of . The frigates stow Template:Cvt of fuel and have a range of at Template:Sfn or Template:Cvt at .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

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 warhead. The SM-1R missiles have a range of Template:Cvt at Mach 2. The vessels also mount a single OTO Melara /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, SQR-19(V) towed array. For weapons fire control, they have Mk 13 weapons control, Mk 92 and SPG-60 STIR missile control, SQQ-89 ASW systems. For electronic warfare they have 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
