The João Coutinho-class corvettes were a series of warships built for the Portuguese Navy for service in Portugal's African and Indian colonies. Initially rated as frigates, they were downgraded first to corvettes and then patrol vessels with age. They were designed in Portugal by naval engineer Rogério de Oliveira, but the urgent need of their services in the Portuguese Colonial War meant that the construction of the ships was assigned to foreign shipyards. Six ships were built; the first three ships were built by Blohm & Voss and the remaining three by Empresa Nacional Bazán. The ships were launched in 1970 and 1971. The relative cheap cost of the design led to it being the basis of several other classes in other navies. From 1970 until the end of the conflict in 1975, the corvettes were used for patrol and fire-support missions in Angola, Mozambique, Guinea and Cape Verde. After the African colonies gained their independence, the corvettes were assigned to patrol duties in Portuguese territorial waters.
