Kharg Island, a small but strategic coral outcrop off Iran’s coast, is facing increasing military tension as the region gears up for potential conflict. This narrow five-mile stretch of land is responsible for routing almost 90% of Iran’s crude oil exports. U.S. officials have referred to it as the “nexus for all the Iranian oil supply.” Kharg Island is known for intimidatingly high storage capacity, with a nameplate of about 30 million barrels. Now, it can store up to 18 million barrels of crude oil, a key component in Iran’s economy.
In recent weeks, Iran has harden the island with additional military defenses. They have laid traps around the perimeter, including anti-personnel and anti-armor mines. The Iranian military has intentionally positioned shore-fired, shoulder-fired surface-to-air guided missile systems, known as MANPADs, to the island. This step goes a long way in boosting its stacked protections. The population on Kharg Island is around 33,000, mostly oil workers – in the thousands.
As tensions escalate, the new U.S. president, Donald Trump, has repeatedly announced that “the war…was won” with Iran. The United States is now sending to the region more amphibious warships, landing craft, and Marines and sailors than during 2015. That’s why two Marine Expeditionary Units (MEU) have recently deployed to the Middle East. They focus on swift-response missions that can be deployed from US Navy amphibious vessels.
Military Maneuvers and Strategic Importance
The new developments around Kharg Island highlight its importance, not just to Iran but to the international balance of power. The U.S. military’s increased visibility in the region indicates a willingness to act if tensions spiral out of control. The presence of two Marine Expeditionary Units indicates a focus on swift amphibious landings and assaults should the need arise.
James Stavridis, a former NATO commander, noted, “Once in position off Kharg, the Marines would need ironclad air and sea superiority over at least 100 miles around the island.” This highlights the importance of complete control of the air and sea. Before we can successfully deploy any ground game, we need to have these domains locked down.
The geopolitical implications extend beyond military concerns. Israel’s opposition leader Yair Lapid emphasized that destroying the terminal on Kharg Island could “cripple Iran’s economy and topple the regime.” Today, this statement is emblematic of the strategic calculations that are today firmly set in favor of the island’s role in Iranian economic stability.
Complications in Regional Dynamics
Alternative export routes do exist. These options have neither been widely implemented nor rigorously tested on a large scale. In 2021, Iran opened the Jask oil terminal to shift oil shipments away from the narrow Strait of Hormuz into the wider Gulf of Oman. It doesn’t have the capacity to replace the tankers’ crucial exports operated via Kharg Island.
Iranian officials have issued external threats with an unmistakable and unequivocal message. Mohammad Bagher Ghalibaf asserted that “Iran’s enemies, with the support of one of the regional countries,” are preparing to occupy one of their islands. He further stated that all enemy movements are under full surveillance and warned that any misstep could lead to “relentless attacks” on vital infrastructure.
Stavridis remarked on the complexities involved should negotiations be pursued: “If the idea is to then bargain with Tehran for an opening of the Strait of Hormuz, it is unclear that the remaining leaders of the regime would be cowed by the threat of losing Kharg.” This vacuum makes diplomatic measures even more difficult and contributes to the tense and volatile state that exists today.
The Broader Implications for Iran and Its Neighbors
Any military action against Kharg Island will have immediate economic repercussions. It would greatly change the balance of power in the region. The island is still critical to Iran’s oil infrastructure, and a shutdown could be disastrous to the country’s economic health. A CIA document from 1984 highlights its importance: “The most vital in Iran’s oil system.”
Going beyond the immediate implications of Trump’s remarks on specific actions, lies a broader strategy toward U.S. engagement in the region. “One bullet shot at one of our men or ships and I’d do a number on Kharg Island. I’d go in and take it,” he stated, illustrating his administration’s willingness to consider aggressive measures.
