Iran fires anti-ship missiles from Qeshm Island toward Gulf of Oman

Iran launched anti-ship missiles from Qeshm Island and its southern coastline toward the Strait of Hormuz and the Gulf of Oman. The launches represent the latest in a series of provocative moves by the Islamic Revolutionary Guard Corps (IRGC) in the region, where roughly a fifth of global oil supply passes through a channel narrow enough that ships can practically wave at each other.

Qeshm Island, Iran’s largest in the Persian Gulf, sits at the mouth of the Strait. The IRGC has turned it into a fortified launch platform over the past several years, complete with underground missile storage facilities that Iran publicly revealed in 2021. Satellite imagery from March 2026 confirmed the deployment of anti-ship missile systems on the island.

What happened and why Qeshm matters

The missiles were fired from Qeshm Island and the Sirik area along Iran’s southern coast, directed toward the Strait of Hormuz and the Gulf of Oman. On August 10, 2026, launches from the same area reportedly targeted an oil tanker near Oman’s coast, though Iranian and US accounts of these incidents have diverged sharply.

In June 2026, Iran made claims about launches directed at US naval vessels. US Central Command denied those claims and responded with counterstrikes on Qeshm’s missile sites. Between May and July 2026, US forces conducted multiple operations targeting Iranian military infrastructure on the island.

Iran has conducted naval exercises involving anti-ship missiles over the Strait of Hormuz since at least 2018. The IRGC’s underground facilities on Qeshm, sometimes referred to as “missile cities,” house significant stockpiles of anti-ship cruise missiles and drones.

The Strait of Hormuz, explained in one stat

About 21 million barrels of oil pass through the Strait of Hormuz every day. At its narrowest, the shipping lane is roughly 21 miles wide, with inbound and outbound traffic lanes each only two miles across.

Tanker attacks in the Gulf of Oman in 2019 briefly pushed Brent crude up by several percentage points in a single session.

US response and the escalation cycle

The multiple operations against Iranian positions on Qeshm between May and July 2026 demonstrate a willingness to strike directly at the infrastructure enabling these launches. Iran’s underground facilities were specifically designed to absorb punishment and remain operational.
