NEW DELHI: United States’s third warship is heading towards the Middle East, with some reports suggesting a possible movement towards the Strait of Hormuz to deploy around 2,200 Marines for a potential operation involving Iran’s Kharg Island. At the centre of these developments is USS Tripoli, an amphibious assault ship capable of transporting, landing, and supporting ground troops and their equipment on hostile or foreign shores.
The deployment comes amid rising tensions involving the US, Israel, and Iran, with global oil routes and regional stability increasingly at risk. According to Sunday Guardian, the warship’s movement has triggered speculation about whether Washington is preparing for a deeper military role in the evolving conflict.The Wall Street Journal reported that the additional Marines would be ferried by the Tripoli to the Middle East. Those Marines are coming from the Okinawa-based 31st Marine Expeditionary Unit (MEU), a rapid-response force of 2,200 personnel, after the Pentagon ordered the unit to deploy, according to three officials familiar with the plans.
What is USS Tripoli and what makes it significant
USS Tripoli is an America-class amphibious assault ship, designed to function as a mobile military base capable of launching air and ground operations simultaneously. Unlike conventional warships, it combines the capabilities of an aircraft carrier and a troop transport vessel.At around 844 feet in length, the ship carries advanced aviation assets including F-35B fighter jets, MV-22 Osprey tilt-rotor aircraft, and MH-60 Seahawk helicopters. These platforms allow it to conduct surveillance, airstrikes, troop deployment, and logistical missions.According to CNN and The Wall Street Journal, the ship is linked to the deployment of the Okinawa-based 31st Marine Expeditionary Unit, a rapid-response force comprising approximately 2,200 personnel.
Can USS Tripoli operate in shallow waters?
Despite its amphibious role, USS Tripoli does not enter shallow coastal waters. Its design as a large surface warship means its operations are restricted by its draft, which is about 10.7 metres (around 35 feet).This requires a minimum water depth of roughly 12 to 15 metres, preventing the ship from moving close to shorelines or beaches. Instead, it remains positioned offshore during operations.From this distance, aircraft such as helicopters and F-35Bs carry out missions inland, while smaller vessels and hovercraft transport Marines and heavy equipment to the shore. This approach allows the ship to support amphibious assaults without exposing itself to the risks of shallow waters.These operational characteristics are based on standard US Navy specifications for America-class amphibious assault ships.
Where is USS Tripoli now
Maritime tracking data cited by CNN indicates that USS Tripoli was recently approaching the Malacca Strait near Singapore, a key maritime chokepoint. It has also been reported south of Sri Lanka, suggesting its movement across the Indian Ocean towards the North Arabian Sea.US Navy vessels often limit public tracking during sensitive deployments but may briefly enable transponders in congested shipping lanes to ensure safe navigation, according to CNN.
Why Kharg Island is central to the discussion
Kharg Island has emerged as a focal point in the current strategic calculations because of its outsized role in Iran’s energy and maritime ecosystem. Located in the Persian Gulf, roughly 25 kilometres off Iran’s coast, the island serves as the country’s primary oil export hub, handling nearly 90% of its crude shipments, according to Axios. This makes it not just an economic asset but a geopolitical pressure point tied directly to global energy markets.Control, disruption, or even the threat of action around Kharg Island has immediate implications for oil supply chains. Any instability here can trigger volatility in global crude prices, given that a significant portion of the world’s oil trade passes through the nearby Strait of Hormuz. As Reuters reports, securing this corridor remains central to US military planning, with options ranging from naval escort missions to more aggressive measures involving ground forces.The island’s importance also lies in its symbolic and tactical value. Targeting or occupying Kharg would directly impact Iran’s revenue streams, potentially limiting its ability to sustain prolonged military operations. However, such a move carries substantial risks. The island is within range of Iranian missile and drone systems, meaning any deployment of US Marines would place troops in a highly exposed environment. Military experts cited by Axios caution that while Kharg is critical, holding it may not necessarily force Iran to concede, especially if Tehran retaliates by disrupting other parts of the supply chain.
Wider military planning and risks
The movement of USS Tripoli comes against the backdrop of an expanding set of military options being weighed by the United States as the conflict enters a more uncertain and potentially escalatory phase. According to Reuters, the Trump administration is considering reinforcing its presence in the Middle East with additional troops and naval assets to strengthen operational flexibility. These deliberations are not limited to symbolic deployments but are tied to concrete objectives such as securing commercial shipping routes through the Strait of Hormuz and countering Iran’s military capabilities.One of the central considerations is ensuring the safe passage of oil tankers through the Strait, a critical global chokepoint. This could involve a combination of naval escorts, air cover, and surveillance operations. However, sources cited by Reuters indicate that more aggressive scenarios are also under discussion, including the possibility of deploying ground forces along Iran’s coastline or at strategic sites such as Kharg Island. Such options would mark a significant escalation, shifting the US role from deterrence to direct territorial or operational engagement.The risks associated with these plans are substantial. Any deployment of ground troops would expose US personnel to Iran’s missile and drone capabilities, which have already demonstrated reach across the region. Even limited operations could trigger retaliatory strikes, potentially widening the conflict beyond its current scope. Additionally, there are political risks for the administration, given domestic sensitivities in the United States around prolonged military engagements overseas.Officials have maintained that no final decision has been taken, emphasising that all options remain under consideration. The presence of amphibious platforms like USS Tripoli, capable of rapidly deploying Marines and supporting air operations, provides the US with strategic flexibility. However, it also underscores how quickly the situation could shift from positioning to active intervention, depending on how events unfold in the coming days.
The bigger picture: Offshore power projection
The deployment of USS Tripoli reflects a broader US strategy of projecting military power without direct coastal entry. While the ship is designed for amphibious warfare, its inability to operate in very shallow waters highlights a key operational principle — modern amphibious ships act as offshore command centres rather than beach-landing vessels.By combining air power, mobility, and troop deployment capabilities, USS Tripoli enables rapid-response operations while maintaining a safe distance from hostile coastlines.
