Reina Sofía (F-84) is the fourth of six Spanish-built Santa Maria-class frigates, based on the American Oliver Hazard Perry class design, of the Spanish Navy. Laid down on 12 October 1987, and launched on 19 July 1989, Reina Sofía was commissioned in service on 30 October 1990. She is named for Queen Sofía of Spain. All of these Spanish frigates have the length of the later Oliver Hazard Perry frigates, and have a wider beam than the US Navy design, and therefore able to carry more top weight. Fin stabilizers are fitted.
