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.

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

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.

Qeshm's wartime profile sharpened through 2026. In March 2026, Iranian Foreign Ministry spokesman Araghchi accused the United States of striking a freshwater desalination plant on the island, calling it a "blatant and desperate crime" even as Iranian drones struck a desalination plant in Bahrain the same cycle. 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. On 31 May-1 June 2026, US Central Command struck radar installations and drone command-and-control sites on Qeshm Island, describing the strikes as "measured and deliberate" self-defence after Iran shot down a US MQ-1 drone, dealing a direct blow to Iran's Hormuz surveillance network.

On 26 June 2026, CENTCOM struck missile and drone storage facilities on Qeshm Island in the first US kinetic strike on Iranian soil since the 16 June Islamabad MOU. CENTCOM cited IRGC drone attacks on the Singapore-flagged container ship M/V Ever Lovely (25 June) and the tanker Kiku in the IMO Hormuz corridor as a clear Ceasefire violation and released footage of the strike. The operation also targeted coastal radar sites near Sirik.

Cancian and Park (CSIS) had warned on 27 May that high munitions expenditure in Operation Epic Fury had created a window of vulnerability, a constraint that shaped the calibrated scope of earlier CENTCOM strikes rather than broader infrastructure destruction.

More questions

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

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.

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

How the World Sees Them

Iran

Qeshm is sovereign Iranian territory; Tehran frames US strikes as attacks on civilian life requiring international condemnation while simultaneously operating IRGC naval assets from the island.

Gulf States

Bahrain and neighbouring Gulf states view Qeshm primarily through the lens of IRGC power projection; its proximity to their coastlines makes any military exchange on the island a direct threat to tanker traffic.

United States

CENTCOM treats IRGC Navy facilities on Qeshm as legitimate military targets; the 31 May-1 June strikes on radar and drone C2 were described as measured self-defence, not full escalation.

Shipping Industry

Tanker operators treat Qeshm and the surrounding Hormuz chokepoint as the highest-risk maritime corridor globally; roughly one fifth of world oil supply passes within range of any exchange.
