From Italy, Iran ordered 6 Lupo-class frigates, capable of anti-submarine warfare and outfitted with Otomat missiles. In 1978 Iran ordered 8 Kortenaer-class frigates from the Dutch, each one equipped with Mk. 46 torpedoes, Harpoon missiles and Sea Sparrow anti-aircraft missiles. In the same year Iran sought to order a further four Bremen-class frigates (similar in design to the Korteaer class).
