The Santa María class of guided missile frigates is the Spanish Navy's designation for six warships based on the United States Oliver Hazard Perry-class frigates. Spanish ships have a slightly bigger beam and were built with a greater weight reserve for future improvements. Other changes from the basic model include Meroka replacing Phalanx and a RAN-12L air search radar to provide low horizon coverage against sea skimmers cueing the Meroka CIWS mount. The Nettunel EW suite (based on the Italian Nettuno built in Spain) replaced the SLQ-32 system fitted aboard US ships. The first ship Santa Maria entered service in 1986.

They are expected to be replaced by the new Bonifaz class starting around 2028.
