Iran says its small subs deployed to Strait of Hormuz as expert explains threat: ‘Vulnerable to detection’

Iran has announced the deployment of small Ghadir-class submarines to the Strait of Hormuz, describing them as an "invisible guardian" of the strategically vital waterway. Rear Admiral Shahram Irani, commander of Iran’s navy, highlighted the submarines’ role in reinforcing Tehran’s control over the strait amid escalating tensions with the United States and the collapse of peace negotiations. The move comes as Iran seeks to assert dominance over the region, which is critical for global oil shipments. Despite the announcement, defense experts have expressed skepticism about the strategic impact of these mini-submarines. Tom Shugart, a retired U.S. Navy submarine warfare officer, noted that while the vessels could pose a threat to U.S. naval forces, their limited range, firepower, and endurance significantly constrain their operational effectiveness. The diesel-electric submarines rely on battery power for quiet operation but must periodically surface to snorkel and recharge, making them vulnerable to detection by sonar and radar. The deployment underscores Iran’s broader strategy to leverage asymmetric naval capabilities in the shallow waters of the Persian Gulf, where conventional naval forces face unique challenges. However, the lack of air-independent propulsion systems in these submarines limits their stealth and endurance compared to more advanced models. This vulnerability reduces their potential to disrupt maritime traffic or challenge superior naval powers over extended periods. The situation in the Strait of Hormuz remains a focal point of geopolitical tension, as the narrow passage is a critical chokepoint for global energy supplies. Iran’s militarization of the area, including the use of mines and small naval assets, raises concerns about the security of international shipping lanes and the potential for conflict escalation. The U.S. continues to maintain a naval presence to ensure freedom of navigation and deter Iranian aggression, highlighting the ongoing strategic contest in the Gulf region.
