Why Kharg Island is key to Iran—and the risks of a potential US ground assault

As tensions escalate between the United States and Iran, focus is shifting to Kharg Island—an oil hub that plays a critical role in Iran’s economy and the global energy market.

Located off Iran’s coast, Kharg Island handles roughly 90% of the country’s crude oil exports, making it a strategic target in any potential military operation. Its infrastructure is designed to accommodate large oil tankers, and experts say disrupting operations there could significantly impact Iran’s ability to generate revenue.

Recent US military movements in the region—including amphibious warships and Marine Expeditionary Units—have fueled speculation that Washington could attempt to seize the island. These specialized units are capable of rapid assaults, but analysts warn such an operation would come with serious risks.

To reach Kharg Island, US forces would need to navigate the Strait of Hormuz, a narrow and heavily defended waterway where Iran has positioned drones, mines, and missile systems. Military experts say any assault would require overwhelming air and sea control, and even then, US forces could face significant casualties.

There are also humanitarian concerns. Thousands of civilians—primarily oil workers—live on the island and would need to be evacuated or secured during any conflict. Meanwhile, Iran has reportedly bolstered its defenses in recent weeks, adding surface-to-air missiles and laying mines around key areas.

Even if successful, some analysts question whether capturing Kharg Island would achieve broader strategic goals. While it could disrupt Iran’s oil exports, it may not be enough to force Tehran to reopen critical shipping lanes or change its position in the conflict.

Regional allies are also urging caution, warning that a ground assault could escalate the war further and trigger retaliation across the Middle East.

As the situation develops, Kharg Island remains at the center of a high-stakes calculation—one that could have far-reaching consequences for global energy markets and regional stability.
