IRIS Deylaman (78) is the latest guided-missile frigate addition to the inventory of the modern Islamic Republic of Iran Navy (IRIN). The 1,500-ton vessel is part of the growing, locally-sourced Moudge-class currently (2023) encompassing sister-ships Jamaran, Sahand, and Dena. Seven ships-in-series are planned for the group which has been under active contruction since 2001. Commissioned service of the lot began in 2010 to much state-sponsored fanfare.
Deylaman's keel was laid down in 2017. She was formally commissioned into IRIN service on November 27th, 2023.
NOTE: IRIS Deylaman directly succeeds IRIS Damavand which was lost during a storm in the Caspian Sea during January 2018.
The vessel takes on a modern appearance with a noticeable reduction of exterior protrusions to promote a stealthier profile. The forward superstructure is stepped and seats the bridge section. The main mast works are exposed and of a lattice-type design. The smoke funnels are of a low-profile design and positioned aft of midships. The second mast works is seated at midships proper. A turreted deck gun is seen at the forecastle with a hangar / helipad section added over the stern to serve a navalized rotorcraft for Over-the-Horizon (OtH) work.
Structural dimensions include a running length of 312 feet, a beam of 36.4 feet, and a draught down to 10.7 feet.
Internally, the operating crew numbers 140 men. The installed propulsion scheme involves a conventional arrangement encompassing four diesel generators of 740 horsepower output coupled with 2 x Engines offering 10,000 horsepower. This propels the ship to open-water speeds of 30 knots under ideal conditions. Twin 8-tube chaff launchers assist the Electronic Warfare (EW) suite and the radar fit is of an an "Asr" 3D PESA type.
The warship is armed through ballistic, missile, and torpedo measures. This includes a 76mm Fajr-27 series turreted deck gun backed by a single 30mm or 40mm autocannon and twin 20mm Oerlikon autocannons. A pair of 12.7mm Heavy Machine Guns (HMGs) serve in the extreme close-in defense role (interception / boarding actions). The vessel is outfitted with 4 x Mehrab Surface-to-Air Missiles (SAMs)a as well as Noor (or Qader) anti-ship missiles. Rounding out the armament suite are twin 324mm triple-torpedo tubes.
All told, with its broad weapons set and multi-mission design approach, the ship can search, track, and engage aerial, surface, and undersea threats.
