The Iranian Ministry of Defense showcased various new technologies, alongside existing elements across various domains, at its booth during the DIMDEX 2024 exhibition in Qatar. A standout exhibit was the model of the Fateh-class submarine.
Inquisitive about this display, Naval News engaged with Iranian booth representatives. According to these officials, the notable modification featured in the submarine is an air-independent propulsion system (AIP) plug. Iranian Navy plans to replace the Fateh-class submarines’ batteries with AIP system.
Reportedly, Iran’s esteemed Malek Ashtar University of Technology (MUT) has been diligently working on integrating this capability into Fateh-class submarines for a considerable period. In addition to working on new technology projects, the university has the capability of testing various naval systems.
The official disclosed that the project is underway, with plans to install the AIP system on the first Fateh-class submarine within approximately a year. After assessing the results on the initial submarine, the modernization process will extend to other boats in the class.
Naval News’ analysis of the model suggests the incorporation of a Stirling-like propulsion system. It is anticipated that the addition of AIP technology will significantly enhance the operational capabilities of these submarines, notably extending their underwater endurance, a key attribute for diesel-electric submarines.
The Fateh-class submarine stands as a significant advancement in Iranian shipbuilding, marking a qualitative leap from its predecessor, the Gadir-class. The surfaced displacement of the Gadir-class was a modest 120 tons, whereas the Fateh-class boasts a significantly larger displacement of around 600 tons.
The Fateh-class submarine deploys its weaponry from four 533 mm torpedo tubes located in the bow. Media reports indicate that its armament includes mines, torpedoes, and anti-ship missiles. Local sources have reported that the Fateh-class submarine has the capability to dive to a depth of 200 meters, showcasing its respectable underwater capabilities. Moreover, it is reported to have an endurance of up to five weeks at sea, underscoring its sustained operational capacity. The Fateh-class submarine exemplifies a substantial advancement in Iran’s naval capabilities.
