The Persian Gulf-class is a new class of destroyer warship being constructed by Iran for the Iranian Navy. The country has invested considerable resources in local design, development, and production of many systems of war - including all-modern combat ships. The class was ordered on September 18th, 2012 and the keel has since been laid according to reports.
At its core, the Persian Gulf-class will have a displacement in the 6,500 to 7,500 tonne range and feature an overall length of 505.2 feet, a beam of 59 feet, and a draught of 16.4 feet. The crew will number about 240 personnel to undertake various tasks about the ship - including support of a modest air arm charged with management and operation of 2 x SH-3 Sea King navy helicopters by way of a combination hangar/deck section over the stern.
The propulsion scheme is set to feature 2 x 18MW gas turbines outputting 24,000 horsepower for dash speeds. This will be coupled to 2 x 4MW diesel engines developing 5,400 horsepower for general cruising actions. Maximum speeds in ideal conditions will reach 25 knots (nearly 30 miles per hour) and range is estimated out to 8,000 nautical miles (about 9,200 miles). The arrangement will most likely be a form of CODAG (COmbined Diesel-And-Gas) or CODOG (COmbined Diesel-Or-Gas). Six 1MW electric generators, outputting an additional 1,300 horsepower, also figure into the mix. All this equipment will be set to drive twin shafts under the stern.
The "Asr" sensor suite will figure into the warship's design. This is a locally developed, all-modern 3-D Passive, Electronically-Scanned Array (PESA) radar system to tackle search, track, and engagement functions at up to long ranges. The system can be established at land positions or on moving warships, such is its tactical flexibility. The system was unveiled to the public in 2013.
Beyond this, the class will be outfitted with the usual destroyer weapon elements including a turreted main gun of (currently) unknown caliber or make, support for Sayyad-2 anti-aircraft missiles, and support for the "Noor" or "Ghader" anti-ship / cruise missile families. Beyond this, the craft will be outfitted with several digitally-controlled Close-In Weapon Systems (CIWSs).
On the whole, the Persian Gulf ships will be able to operated independently or as part of the main Iranian fleet. In either case, the vessels will be able to deter or counter inbound aerial threats, ranged surface threats, combat undersea threats, or assault inland positions as needed. The helicopter pair will be able to provide an Anti-Submarine Warfare (ASW) and Over-the-Horizon (OTH) capability when called upon.
Other expected features will include a modern CounterMeasures (CM) suite as well as hull-mounted sonar.
