The Moudge-class is a frigate warship group developed and constructed by local Iranian industry. It serves the modern Islamic Republic of Iran Navy (IRIN) with seven total vessels were planned for the series: three having been completed, four under construction (as of December 2018), and two in active service. IRIN Damavand (F-77) makes up one of the group's number, the third of the class to be launched (2013). She was heavily damaged in a January 2018 incident which has subsequently removed her from active service with the IRIN.
Displacement runs 1,500 tons. Dimensions of the vessel include a running length of 310 feet, a beam of 36.4 feet, and a draught of 10.7 feet. Drive power is from 2 x 10,000 horsepower output engines coupled with 4 x Diesel generators giving the vessel a maximum speed of 30 knots in ideal conditions. Aboard is a complement of about 130 to 140 personnel.
Armament consists of 1 x 76mm Fajr-77 turreted deck gun over the forecastle, 4 x Qader Anti-Ship Missiles (ASMs), 2 x Mehrab Surface-to-Air Missiles (SAMs), 1 x 40mm Anti-Aircraft (AA) gun, 2 x 23mm AA autocannons , and 2 x 324mm triple torpedo tubes.
Her outward design is conventional with modern fighting frigates. The turret is in the "A" position towards the bow with the helipad at the stern (supporting a single medium-lift transport/Anti-Submarine Warfare helicopter). The bridge section is of a low profile design with an exposed mast seated just aft. Aft of this is a radar fit and enclosed, low-profile smoke funnel. The helipad makes up the last section of the ship.
January 2018 - IRIN Damavand struck the breakwater at Bandar-e-Anzali on January 10th, 2018 and ultimately sank due to the extensive damage. It will most likely be struck from active status with the Iranian Navy as a result.
