Fateh (Conqueror / Victor) "semi-heavy" submarine

The 500-600 ton Fateh (Conqueror / Victor) is among "semi-heavy" submarines belonging to Iran's Army which will probably been used to carry out coastal missions along with other submarines, including Ghadir. The submarine is equipped with state-of-the-art defensive and offensive weaponries such as torpedoes and marine mines. It can operate more than 200 meters below the sea surface for near five weeks. Amid efforts to tighten naval security in the country's southern coasts, the most modern domestically-built Fateh submarines will join Iranian Navy in the near future, Fars news agency reported on 05 October 2011.

Iran will release two new submairines of own production, Deputy of Iran's Army commander on research issues Farkhad Amiri said, Fars reported 18 January 2012. Amiri noted that the "Fateh" submarine will be put into operation in the beginning of new Iranian Year (started on March 21). He also added that it was planned to install 12 Sonar on the Fateh submarine. Sonar is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect other vessels.

Two types of technology share the name "sonar": passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes. "Its planned to have both passive and active sonar on Fateh submarine," Amiri noted. "Sonar will help the submarine to detect and take active measures against enemy divers and other threats." Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. Acoustic location in air was used before the introduction of radar. Sonar may also be used in air for robot navigation, and SODAR (an upward looking in-air sonar) is used for atmospheric investigations.

The Iranian defense minister announced 10 Dec 2013 that the construction and testing of the country's indigenous semi-heavy submarine Fateh (Conqueror) had been completed and will be delivered to naval forces upon being armed. Speaking on the sidelines of Iran's Seventh Scientific Command and Control Conference in Tehran, Brigadier General Hossein Dehqan further stated that the testing operation of the first model of the submarine was successfully completed and Fateh will be delivered to the naval forces of the Islamic Revolution Guards Corps (IRGC) after it is adequately equipped and armed.

One suspected Fateh-class submarines was spotted in Astrium imagery in the water near the Bostanu Shipyard near the Strait of Hormuz on 27 October 2013, according to a Janes report. A second submarine appeared to be under construction at the Bandar Anzali Naval Base on the Caspian Sea as of 27 September 2013. The new Fatah-class submarine was briefly shown in a video montage that Iranian television aired in February 2014. The clip, which the regime broadcast to stir national pride in the country's military achievements, showed a submarine with a 40-meter waterline docked at the Bostanu shipyard.

"The Defense Ministry will take another step in developing the operational capabilities of this strategic force after this advanced submarine joins the Navy fleet in future", Brigadier General Hossein Dehqan, Iran's Defence Minister, stated in comments quoted by news agency Fars. Little information is known on the Islamic Republic of Iran's Fateh-class submarines. Locally-assembled, each is classed as a semi-heavy submarine, diesel-electric powered and armed with a mixture of torpedoes and mines.

Fateh is an upgrade over the 29-meter Ghadir class of subs that the Iranians had been building for years. In August 2010, four domestic-made Ghadir class mini submarines joined the Iranian Navy which are capable of launching torpedoes as well as precision targeting. The Ghadir submarine was first unveiled in 2007. The 120-ton vessel has excellent shallow depth performance, and can carry out long-term coastal missions. The Iranian fleet had at leasat 11 and possibly as many as Ghadir submarines.

Janes reported that "While the Ghadir was widely presumed to be based on a North Korean design, the new Fateh class is significantly bigger than the largest submarine known to be produced by the North Koreans: the 39 m K-300 (Sang-O II) class." This is strange, since the Fateh class is 40 meters long, only slightly larger than the 39 meter K-300 (Sang-O II).

In recent years, Iran has made important breakthroughs in its defense sector and attained self-sufficiency in producing important military equipment and systems. The Islamic Republic has repeatedly assured that its "military might poses no threat to other countries, stating that Tehran's defense doctrine is based on deterrence only".

IRIN commander, Rear Admiral Habibollah Sayyari stated up to 20 Fateh-class submarines would be constructed in the future. Reportedly, the Fateh submarines will be equipped with torpedoes, missiles, and mines. In April 2016, Fateh hull one was still undergoing sea trials with the goal to be certified operational by the end of 2016, but as of January 2017, the IRIN had yet to declare the Fateh submarine operational.

President Hassan Rouhani unveiled a built-in submarine called "Fatah", which Iranian media say is the most advanced submarine in Iran equipped with a rocket launcher. The launch ceremony of the submarine was held in Bandar Lengeh on 28 November 2018. Amir Hatami, the minister of defense and support of the armed forces of Iran, said the submarine has a "secure and integrated telecommunication system" from "sonar systems, electric drift, combined battle management, sub-surface missile guidance, torpedo guidance, electronic and telecommunication wars."

The IRNA news agency reported in the Fateh coordinates that the submarine weighs 527 tons and is the first semi-heavy submarine made by Iran; it also "has the ability to move at a depth of 200 meters in normal shape and has a depth of reach of 250 meters." The report says the conqueror "has a 35-day seaworthiness," and "has four 533-mm caliber thruster headquarters and can carry eight-seater and two torpedo-reservations."

The Fars News Agency reported in a report that the construction of this submarine "resulted in more than 4,200,000 hours of work and efforts by defense industry experts in cooperation with 500 partner networks, including 48 design centers, 120 industrial centers, 80 Knowledgebased companies, 57 centers University and 195 research centers of the country.

Hassan Rouhani said that the submarine spent $ 68 million on top of Hormozgan province officials and officials. According to him, "If we were to buy this submarine out of the country, we would have to spend $ 250 million and perhaps not give us the parts we needed."

In an interview with Radio Farda on the history of Iran's submarines, military analyst Hossein Aryan said Iran has unveiled its first semi-heavy submarine called Fatah, which is likely to be completed and optimized for the whale submarine. According to Admiral Hossein Khanzadi, commander of the Navy, "next generation of submarine conquerors" will be built. He stressed that the Fatih is not suitable for operations in the shallow water of the Persian Gulf, due to its displacement weight and characteristics, but it is undoubtedly a good option for operation in the Oman Sea and waters beyond the Kiloglu submarine.

The Islamic Republic of Iran Navy (IRIN) officially commissioned its first indigenously developed Fateh-class submarine on 17 February 2019. The ceremony was held at the Bandar Abbas naval base and was attended by President Hassan Rouhani. Defence Minister Amir Hatami was quoted as saying that the submarine weighs 600 tonnes and is capable of launching torpedoes and anti-ship missiles. The Iranian media also reported that it can dive to 200 m and has an endurance of five weeks.
