Arnala class was an Indian designation for the Petya III-class vessels of the Indian Navy.^[1]

Although these vessels were classified as frigates in the Soviet Navy, they were classified by the Indian Navy as anti-submarine corvettes due to their role and smaller size. Vessels of the class were named for Indian islands.
