The Commander-in-Chief of the Navy of the Islamic Revolutionary Guards Corps of Iran (IRGC), Admiral Aliréza Tangsiri, who had visited the strategic islands of southern Iran, the Little and Big Tomb, on Friday, December 25, implicitly warned the U.S. fleet against any foolishness: “The U.S. fleet has been…
the IIR is ready to protect and secure its maritime borders in the most perfect way. Accompanied this Friday by a number of ICN leaders and officials, Admiral Tangsiri visited the two islands in the Persian Gulf where he conducted an inspection tour and inquired about the readiness of the naval forces on the ground.
He essentially insisted on maintaining “total combat readiness”, “vigilance and intelligence monitoring in the context of the sensitive mission of the armed forces deployed there”.
“Our field investigations show that the forces, systems and equipment are in a state of readiness required to defend the maritime borders and the interests and security of our country,” he said. The Little and Big Tomb and Bou-Moussa Islands are of great strategic and economic importance, located in the eastern Persian Gulf and overlooking the Strait of Hormuz, through which about 40% of the world’s oil production passes daily. These islands are all the more important as the small Emirates have territorial claims against them and that under the effect of the somewhat electric atmosphere that currently reigns in the Persian Gulf, where America, in the absence of any military action worthy of the name, is sometimes bulging the torso of its B-52s and sometimes exposing under the cameras, its USS Georgia, they could be the starting point of the mega clash. On Thursday and in reaction to the ultra media coverage of the arrival of the USS Georgia in the Persian Gulf, the first deputy speaker of the Iranian Parliament, Seyyed Amir-Hossein Ghazizadeh Hashemi, recalled last Tuesday that the Iranian forces waiting today at the turn of the USS Georgia, are the same ones who shot down in June 2019 an RQ-4 in the skies over southern Iran. “These same forces would know how to catch the USS Georgia with a “fishing net”.
But what is the point of this metaphor? “Of course, everyone understands that the expression ‘fishing net’ is a metaphor, notes political scientist Hanizadeh. The enemy must seize the power and capacity of the Iranian armed forces in the Persian Gulf region. But Ghazizadeh stressed a very important point that Iran’s enemies should pay attention to. The Persian Gulf is about 56 km wide, in the Strait of Hormuz.
The waters are generally very shallow, with a maximum depth of 93 meters and an average depth of 50 meters. And in most other areas, the depth of the Persian Gulf reaches about 30 meters. A submarine must be at least ten to twenty meters from the seabed if it does not want to hit a rock. One can therefore imagine that in some cases, these submarines must be less than ten meters from the surface of the water. So we can easily understand the metaphor of Ghazizadeh. At such a distance, the USS Georgia will not escape neither the Iranian anti-ship missiles nor Iran’s sonar-armed helicopters, which the CGRI has just unveiled not so long ago”.
In October, the CGRI Navy acquired SRN6 hovercrafts, AB212 anti-surface helicopters, SH3D anti-surface helicopters and F27 maritime patrol aircraft. Iranian helicopters have been equipped with sonar, as they are used to fish enemy submarine vessels.
It was in 2014 that the Iranian Navy unveiled a USS Geaorgia: three homemade combat, simulation and radar systems. The sea-based “Samen” surface fire control system, capable of tracking surface and air targets and simultaneously intercepting 40 surface targets and one air target. In addition, a simulation system for the diver exit of Iranian Midget-type submarines, which can also be used to exercise the emergency exit of naval personnel, was unveiled. But the package was recently completed with the latest military equipment presented by the Iranian Navy, the S and X navigation radar project, which can be used in a network with data fusion. And the word network is of paramount importance when it comes to tracking, intercepting and then “capturing” a submarine. After all, since the USS Georgia is running on nuclear fuel it is not recommended to strike it in the middle of the Persian Gulf. This radar device can also send information and data on the target, direction, speed and distance, and connect to various navigational aid systems.
But the ultimate of this Iranian fishing net for the USS Geoargia was unveiled on December 11th of this year: a helicopter-portable sonar system that is supposed to detect submarines was exhibited at an Iranian Navy fair. The system is capable of detecting submarines using electromagnetic sensors, communicating with other indigenous units, and transmitting information to the fire control system to launch torpedoes.
But the accuracy of the system’s structure is similar to that of the AN / AQS-13 system, which is an immersion sonar system for U.S. Navy helicopters. In the test, experts said it does even better. This system is considered the basis of a sonar system based on active-state operation at medium and high frequencies. This system was intended for helicopters that typically flew from U.S. aircraft carriers and were responsible for anti-submarine defense in close circles to the fleet.
The main difference between the current plan made by the Navy and the original plan is the addition of the passive search mode to this sonar system, in which the sonar system only detects surrounding sounds without revealing its location. So it is not so easy to stand in front of the Iranian coasts and shoot underwater. This difficulty has already appeared to the US surface ships that called for help to the USS Georgia but the latter could not escape either.
With the addition of this system to the Iranian Navy’s SH-3D helicopters, it can be said that the complete cycle of detection, pursuit and destruction of enemy submarines by these helicopters is completed and a new ring of defense is added to the country’s military capability.
