The United States military destroyed five Iranian crude oil tankers on Tuesday in the Gulf of Oman and near Kharg Island in the Persian Gulf, following two separate ballistic missile attacks by Iran's Islamic Revolutionary Guard Corps (IRGC) on an American warship, according to US Central Command (CENTCOM). No US personnel were reported injured in either of the Iranian strikes.

The Tankers Destroyed and How It Unfolded

CENTCOM identified the four vessels destroyed in the Gulf of Oman as M/T Kaviz, M/T Charminar, M/T Horizon 1, and M/T Riesco. A fifth tanker, M/T Derya, was struck near Kharg Island, Iran's principal crude oil export terminal. US forces reportedly ordered crews to abandon the ships before the strikes were carried out, and no casualties among the tanker crews were reported by CENTCOM.

The American warship successfully evaded both missile attacks, which occurred over two consecutive days prior to Tuesday's retaliatory strikes, according to CENTCOM. The military did not disclose the identity of the targeted warship, the precise location of the missile attacks, or the number of ballistic missiles fired.

Part of a Broader US Campaign Against IRGC Shipping

Tuesday's operation was the second such US strike on Iranian oil tankers in four days. On 5 September, CENTCOM forces destroyed three Iranian crude oil carriers after the IRGC allegedly attempted to attack a US aircraft carrier and a guided-missile destroyer. Taken together, the two operations have resulted in the destruction of eight Iranian tankers within less than a week.

CENTCOM described all the vessels as crude oil carriers operated by the IRGC, stating they formed part of a multibillion-dollar network used to finance the Iranian military organisation and its regional proxies. The characterisation frames the strikes as targeting an economic lifeline for Iran's military apparatus rather than purely commercial shipping.

Strategic Significance of Kharg Island

Kharg Island, located in the northern Persian Gulf, has historically served as the primary terminal for a large share of Iran's seaborne crude oil exports. Military activity in its vicinity is considered particularly sensitive, as disruption there can ripple through global energy markets. This marks a notable escalation in the geographic scope of US operations, which previously focused on the Gulf of Oman.

Implications for Global Oil Markets and India

Any sustained disruption to shipping through the Gulf of Oman and Persian Gulf could affect tanker insurance premiums, freight costs, and global crude oil prices. India, which depends heavily on imported crude oil, is among the countries that could face downstream consequences if the security situation in the region deteriorates further. Analysts have flagged that a prolonged standoff near Kharg Island carries the potential to tighten global supply at a time when energy markets remain sensitive to geopolitical shocks.

The escalating exchange between US forces and the IRGC marks a sharp intensification of tensions in the Persian Gulf, with both sides now having carried out multiple offensive operations within days of each other.
