Nahang

The Nahang (Whale) is an Iranian midget submarine designed for coastal defense and special operations. It is believed to be capable of deploying divers and possibly torpedoes, though its exact capabilities remain largely unconfirmed.

Developed in the early 2000s by Iran's Marine Industries Organization, the Nahang was designed to bolster asymmetric warfare capabilities in the shallow, congested waters of the Persian Gulf. The sole vessel of the class, Nahang-101, was officially commissioned into the Islamic Republic of Iran Navy in March 2006. While it has not seen active combat, the submarine has participated in numerous naval exercises, serving primarily in reconnaissance, mine-laying, and special forces insertion roles. Today, the Nahang remains operational as a training platform and technology testbed, having laid the developmental groundwork for Iran's subsequent Ghadir-class midget submarine fleet.
