Background

Qeshm Island is the largest island in Iran, stretching roughly 135 kilometres in the Strait of Hormuz at the entrance to the Persian Gulf, within Hormozgan Province. The strait carries an estimated 20% of global oil trade, making Qeshm one of the most strategically significant pieces of territory in the world. Iran designated it a free trade zone in 1991, attracting light manufacturing and investment.

Its dual character as both a civilian economic zone and a home to IRGC Navy bases creates a persistent strategic ambiguity: strikes on its infrastructure simultaneously threaten civilian life and military capability, a framing both Iran and the United States have exploited throughout the 2026 conflict. On 20 May 2026, Iran's Persian Gulf Strait Authority published formal maritime zone coordinates with Qeshm's tip as the western boundary anchor, giving Tehran a legal instrument to regulate all vessel passage through the strait.

Key Issues
Post-MOU strikes

CENTCOM strikes break the ceasefire at Qeshm

On 31 May-1 June 2026, CENTCOM struck radar installations and drone command posts on Qeshm itself, retaliation for Iran downing a US MQ-1 the week before; the raid gutted the island's role as Iran's forward eyes over Hormuz traffic.

On 26 June, CENTCOM hit missile and drone stores on the island again, its first return to Iranian territory since the 16 June Islamabad memorandum, justified by citing IRGC drone attacks on the container ship Ever Lovely and the tanker Kiku as ceasefire breaches. On the night of 19 July, Iranian state media reported fresh explosions at Qeshm without naming an attributed actor, a claim that, unlike the confirmed May and June raids, carries no independent confirmation.

Common Questions

Reference

What is Qeshm Island?
Qeshm is the largest island in the Persian Gulf, located in the Strait of Hormuz within Irans Hormozgan Province. It hosts a free trade zone established in 1991 as well as IRGC Navy bases, making it simultaneously a commercial hub and a strategic military asset.
Were there explosions at Qeshm Island in July 2026?
Iranian state media reported explosions at Qeshm Island and Bandar Abbas on the night of 19 July 2026, the same night US forces struck targets near Ahvaz further inland. No attributed actor was named for the Qeshm and Bandar Abbas explosions.Source: Lowdown
What happened to Qeshm Island in the Iran war?
US Central Command struck radar installations and drone command-and-control sites on Qeshm Island on 31 May-1 June 2026, calling them measured self-defence strikes after Iran shot down a US MQ-1 drone. Iran had previously accused the US of striking the island's desalination plant in March 2026, a claim the US did not confirm.Source: CENTCOM / Lowdown
What is Iran's Persian Gulf maritime control zone and where is Qeshm Island in it?
Iran's Persian Gulf Strait Authority published formal zone coordinates in May 2026. The western boundary runs from the tip of Qeshm Island (Iran) to Umm Al-Quwain (UAE). All vessels inside the zone must obtain Iranian authorisation.Source: Iranian PGSA / Lowdown
Why is Qeshm Island strategically important?
Qeshm sits inside the Strait of Hormuz, the chokepoint for roughly 20% of global oil trade. It hosts IRGC Navy bases and serves as the western boundary anchor of Iran's formal Persian Gulf maritime control zone. Whoever controls Qeshm controls surveillance of the most critical oil shipping passage in the world.Source: Lowdown
How does Qeshm Island compare to Diego Garcia in the Iran conflict?
Both islands host military infrastructure that became targets or alleged targets during the Iran conflict of 2026. Diego Garcia was struck by Iranian missiles; Qeshm was claimed by Iran to have been struck by the US, though that strike was unconfirmed.Source: event
Was the June 2026 Qeshm Island strike a ceasefire violation?
CENTCOM framed the IRGC drone attacks on the container ship M/V Ever Lovely (25 June) and the tanker Kiku as the Ceasefire violation that triggered the 26 June strike on Qeshm missile and drone storage. Iran disputed the characterisation. The Islamabad MOU, signed 16 June, was the framework both sides claimed the other had broken.Source: CENTCOM
Is Qeshm Island a military or civilian site?
Both. Iran designated Qeshm a free trade zone in 1991 and it hosts civilian infrastructure including a desalination plant. But the IRGC Navy also maintains bases there. This dual-use ambiguity is central to the diplomatic dispute over who is responsible for escalation.Source: Lowdown
Did the US strike Qeshm Island?
Irans Foreign Minister Araghchi alleged in March 2026 that the US struck a freshwater desalination plant on Qeshm Island, calling it a criminal act. The strike has not been independently confirmed.Source: Iranian Foreign Ministry
Why did CENTCOM strike Qeshm Island missile storage in June 2026?
CENTCOM stated that IRGC one-way drones struck the Singapore-flagged container ship M/V Ever Lovely on 25 June 2026 and the tanker Kiku in the IMO Hormuz corridor, calling this unwarranted aggression that violated the Ceasefire. The Qeshm missile and drone storage strike was CENTCOM's response.Source: CENTCOM
Did the US bomb Qeshm Island after the ceasefire deal?
Yes. On 26 June 2026, CENTCOM struck missile and drone storage on Qeshm Island, the first US kinetic strike on Iranian soil since the 16 June Islamabad MOU. CENTCOM cited IRGC drone strikes on commercial vessels in the Hormuz corridor as the justification.Source: CENTCOM / Lowdown
Did an oil spill reach Qeshm Island in August 2026?
Yes. Oil from the grounded tanker Caroline Bezengi, a sanctioned Sovcomflot-linked vessel that ran aground on 21 June, washed onto Qeshm Island's shore by 13 August. Iran's foreign ministry then demanded compensation running into the trillions of dollars for the environmental damage.Source: Lowdown
