Moudge-class frigate

Iran's Moudge class is a family of domestically built light frigates, officially designated as destroyers by Tehran, that combined anti-ship missiles, short-range air defense and helicopter facilities on a roughly 1,500-tonne hull.

Overview

The Moudge, or Mowj, class was the Islamic Republic of Iran Navy's principal indigenous surface-combatant programme. Iran officially described the ships as destroyers, but their approximately 1,500-tonne displacement and armament led Western publications to classify them as light frigates or corvettes. The design developed from Iran's British-built Alvand class and provided the regular navy, rather than the Islamic Revolutionary Guard Corps Navy, with a domestically assembled platform for surface warfare, limited air defense, anti-submarine operations and extended deployments. The class ultimately included five armed ships and the unarmed Zagros signals-intelligence conversion, while a seventh hull, Taftan, remained incomplete.

The ships combined a 76 mm gun, four or eight Noor or Qader anti-ship missiles, a small battery of Mehrab or Sayyad surface-to-air missiles, lightweight torpedoes and a helicopter flight deck. Later hulls received phased-array radars and revised weapon fits, but the class retained limited displacement, a small defensive missile battery and no documented area-air-defense capability. Its operational history encompassed Iran's first naval voyage to the Atlantic without a foreign-port call, regional exercises and several severe accidents.

By the end of the first three weeks of the 2026 Iran war, every confirmed armed ship in the class had been sunk or destroyed. Jamaran, Sahand and Deylaman were struck in port, while Dena was sunk off Sri Lanka during its return from an Indian-hosted fleet review. Zagros was also reported lost, although that claim remained uncertain, and the condition of the incomplete Taftan was not publicly established. The losses transformed the class from a symbol of Iranian naval self-sufficiency into a case study in the vulnerability of a small fleet concentrated at known bases and operating without assured air cover.
