IRGC Tries to Seize U.S. Navy Drone; Two Iranian Boats Destroyed

The U.S. military destroyed two Islamic Revolutionary Guard Corps Navy boats on September 14 after Iranian forces attempted to seize an American unmanned surface vessel patrolling the Strait of Hormuz, U.S. Central Command confirmed. The incident marks the first publicly acknowledged American kinetic action in the strait since September 8.

What Happened

CENTCOM spokesman Capt. Tim Hawkins said “Iranian small boats recently attempted to take possession of a U.S. unmanned surface vessel, but they were unsuccessful after CENTCOM forcefully responded.” A U.S. combat drone fired two missiles at the boats, destroying both craft and killing most of those aboard. Hawkins added that “the surface drone remains under U.S. operational control.”

The military did not immediately disclose the strike. The engagement became public through reporting on September 15, the day after the incident. The attack took place near Larak Island in the eastern approaches to the strait.

Iran’s Account

Iranian officials disputed the characterization of the dead as IRGC personnel. Ahmad Nafisi, Deputy Governor for Security Affairs of Hormozgan province, told the semi-official Mehr news agency that an unspecified number of fishermen were missing and that search-and-rescue operations were under way following what he described as a drone attack off the coast of Kargan. The IRGC Navy had not issued a formal statement as of publication.

The competing accounts follow a pattern visible throughout the conflict. In early September, the IRGC claimed it had destroyed a U.S. Saildrone unmanned vessel at the entrance to Hormuz; CENTCOM denied that account.

Why It Matters

U.S. Navy unmanned surface vessels have taken on expanded patrol and surveillance roles in the Strait of Hormuz since the conflict escalated in mid-2025. The IRGC has previously attempted to seize or disable American naval drones — most recently in 2023 and in July 2025 — but the September 14 episode is the first such attempt in the current conflict phase to result in a confirmed U.S. strike on Iranian vessels.

The strait remains the central pressure point in the broader confrontation. According to U.S. Energy Secretary Chris Wright, 18 million barrels of crude and petroleum products passed through Hormuz in a single recent 24-hour window. Brent crude crossed $101 a barrel on September 9 — the highest close since May — as the pace of naval incidents accelerated, and was trading near $102 as of September 17.

Saudi Arabia is separately working to restore capacity on its East-West pipeline, which was damaged by drone strikes last week. The pipeline offers an alternative crude export route bypassing the strait entirely; full restoration is expected to take up to six weeks, prolonging the period during which tanker traffic through Hormuz carries elevated risk. The Brent and Hormuz oil shock dynamic has made the strait’s security one of the most closely watched variables in global energy markets.

Broader Diplomatic Backdrop

The September 14 incident adds operational friction to an already volatile diplomatic moment. The IAEA Board of Governors voted on September 9 to refer Iran’s nuclear file to the UN Security Council for the first time in 20 years, citing Tehran’s failure to meet monitoring obligations after Israeli and American strikes on its nuclear facilities in June 2025. The Security Council was scheduled to vote Wednesday on renewing the mandate of the panel that monitors Iran sanctions under Resolution 1737; Russia and China are expected to veto the renewal, as they have for four consecutive quarters.

Iran’s Foreign Minister Abbas Araghchi traveled to Beijing this week for talks with Chinese Foreign Minister Wang Yi, his second visit since the conflict began. Beijing and Moscow have both opposed Security Council action against Iran and are pressing for a settlement that curtails U.S. military presence in the Persian Gulf.

According to a GlobalSecurity conflict update from September 16, the parties remain far from a durable agreement, with core disputes over Iran’s nuclear program, sanctions relief, and Hormuz transit protocols unresolved since a June memorandum of understanding effectively collapsed over the summer.
