Iran - Submarines
The General Protection of the Persian Gulf region was transferred to the Revolutionary Guards Navy in 2007 by dividing the logical and specialized work between the Navy and the Guard. It would not be vain to claim that this small blue zone, despite all its small size, is one of the five most sensitive points in the world between the blue zones. From the security discussions between the Gulf states to the passing of heavy amounts of oil and gas derivatives, everything has been handed in to make the area ever at the forefront of regional and global players' attention.
Underwater submarine warfare is a very complex issue of time and cost, which many countries in the world are basically trying to not enter. But the vast amount of threats and defense industry expertise in modern equipment has pushed Iran into a part of the defense technology sector. The Persian Gulf is among the shallow seas of the world where large submarines can not be present. Due to the limited dimensions of the submarine in this sea, it seems that the sub-class of midget subarmines is the best option for operations.
The Persian Gulf region is mostly a shallow water zone, and is a major challenge for most submarines, even ordinary diesel-type vehicles. Basically, this area needs a small, lightweight float in the submarine combat, which can be done at a low cost and, of course, the number of crew members. The ability to launch torpedoes, cruise missiles and, of course, the possibility of deploying land mines is one of the characteristics that the Army's submarine seems to have.
Underwater, the Persian Gulf is, in fact, a complex geographic environment where the types and types of swellings and bulges make it a very difficult environment for common submarines. Specific conditions of Persian Gulf water and its particular physical phenomena in the design of this submarine, including its high water density, aused problems in the warm seasons in the early days of the arrival of Russian submarines. Also, the tide of water in the Persian Gulf, which occurred twice a day, with a height difference of 3 to 4 meters. These variations in water heights change the density of sea water layers, and as a result, both the sound layers and the submarine balance state are affected. There are two indigenous candidates now for this issue. One submarine of Ghadir and other submarines of the Fateh [Conqueror], both built by the Ministry of Defense and delivered to the Navy.
Iran's first serious effort was to develop the sub-surface Ghadir submarine project, which is considered to be a very lightweight submarine, and has been developed for operations in shallow waters. The displacement of Ghadir submarine was about 120 tons. Iran is the only current maker of midget submarines in the world. One of the most interesting and important points about this class of submarines in the world is that it may be somehow said that Iran is currently the only country in the world that is actively developing and serving this class of submarine in the world.
Recently the Fateh / Conqueror has been added to the sub-surface fleet of Iran. Submarine displacement underwater is about 593 tons or 600 tons in class. Other features of this submarine are: the depth of operation is 200 meters, the final depth is 250 meters, its surface speed is 20 kilometers per hour and its underwater speed is 25 kilometers per hour. The duration of the voyage is 35 days. In the weapons section, the status of this boat is as follows: the Conqueror submarine carries 4 torpedoes, 8 mines and 2 torpedoes. But the important thing about the Conqueror is the anti-ship cruise missiles that they can be fired from underwater. According to a statement by the Navy commander of the Army at the ceremony of joining the submarine, a cruise ship anti-ship cruise missile based on the Nasr model was designed to shoot from the submarine, which is, of course, different from the original.
Of course, along with it, the Hwale [Nahang] submarine version must also be added. This single prototype was initiated to develope and validate Iran's ability to design and manufacture larger submarines than the Ghadir class. The Nahang submarine, Iran's second homemade submarine, is reportedly one of the country's "largest" defense projects, thought this claim is hard to square with the small number of people involved.
The Nasr missile is an Iran-made anti-ship short-range missile with a 35-kilometer lead. Fatah can respond to the needs of the Navy in the Persian Gulf and could significantly increase the power of the anti-ship force. Even with the development of cruise missiles attacking ground targets in the country and the development of smaller models of them, it is easy to define a deep attack on the enemy on the ground from underwater for the Army, which is an important development in the combat capability.
At the same time, with the presence of the submarines of the Guards in the Persian Gulf, the submarine combat mission in the Persian Gulf remains under the control of the Navy. A relatively large force which now uses submarines of Ghadir class to carry out operations in areas like the Makren coast and the north of the Indian Ocean.
