Gulf States Under Fire: The UAE's Air Defense Battle and the Wider Cost of the Iran War

When the United States and Israel launched their coordinated strikes against Iran on February 28, 2026, analysts predicted Iranian retaliation would be swift and severe. What few anticipated was the sheer scale of that retaliation against the Gulf states—nor the degree to which it would expose the profound fragility of Gulf security arrangements that had been decades in the making.

In the month since the campaign began, the United Arab Emirates has become one of the most heavily targeted non-belligerent countries in modern military history. According to the UAE Ministry of Defence, as of March 29, Iranian forces had fired 414 ballistic missiles, 1,914 drone sorties, and 15 cruise missiles at Emirati territory. The overwhelming majority were intercepted by the UAE's layered air defense network—its Terminal High Altitude Area Defense (THAAD) systems and MIM-104 Patriot batteries, both acquired from the United States—but the sheer volume of incoming fire has placed extraordinary strain on those systems and the personnel operating them.

The human cost has been limited largely because of this defensive capacity, yet it has not been zero. Eleven people have died in the UAE since February 28, including three military personnel, with 178 others injured. Civilian infrastructure has suffered measurably: debris from intercepted projectiles has rained down on populated areas in Abu Dhabi and Dubai, striking residential neighborhoods, igniting fires, and shattering windows across the city. Dubai International Airport—one of the busiest aviation hubs in the world—was struck in the early hours of one morning, injuring four staff members and forcing a partial evacuation. The iconic Burj Al Arab sustained minor damage from falling intercept debris. A Shahed-type drone struck near the Fairmont The Palm hotel on Palm Jumeirah, causing a significant explosion and fire that injured four people and disrupted the surrounding luxury district.

Perhaps the most strategically significant development came on March 23, when Iranian ballistic missiles struck two data centers near Abu Dhabi. Iran had previously targeted an Amazon Web Services facility in the UAE during earlier phases of regional escalation, but the latest strikes represent a deliberate effort to attack critical digital infrastructure at scale—a dimension of modern conflict that Gulf planners had been warned about but are now confronting in real time.

The targeting of Al Dhafra Air Base—home to US Central Command air operations and a key staging ground for operations against Iran—has been relentless. The base has sustained minor structural damage from secondary explosions. Al Minhad Air Base, operated jointly by the UAE Air Force, the British Royal Air Force, and the Australian Defence Force's Headquarters Middle East, has also been attacked, underscoring that Iran is deliberately targeting coalition military infrastructure on Emirati soil.

Beyond the UAE, the damage has been regional. Saudi Arabia, Qatar, Kuwait, Bahrain, and Oman have all been subjected to missile and drone barrages in what IRGC commanders have framed as retaliation for hosting US military forces and, in their characterization, providing material support to the joint US-Israeli campaign. On March 27, the IRGC formally announced that the Strait of Hormuz is now closed to any vessel traveling to or from ports of the United States, Israel, and their allies—a declaration that, if enforced at scale, represents one of the most consequential acts of maritime coercion since the Second World War.

The Strait of Hormuz carries approximately 20 million barrels of oil per day, representing roughly 20 percent of global seaborne oil trade, along with enormous volumes of liquefied natural gas. Following Iran's IRGC warnings and subsequent attacks on merchant shipping—21 confirmed attacks on commercial vessels as of mid-March—tanker traffic collapsed. The decline was initially estimated at approximately 70 percent, with over 150 vessels anchoring outside the strait to avoid risk; the flow then dropped to near zero. Brent crude surpassed $100 per barrel on March 8 for the first time in four years and reached a peak of $126 per barrel, the fastest price surge associated with any military conflict in recent history. Economists are already describing the disruption as the largest energy supply shock since the 1970s oil crisis.

Washington's response to the Hormuz closure has itself become a source of tension with Gulf partners. On March 9, President Donald Trump announced his intention to seize control of the Strait; on March 19, US forces began a dedicated military campaign to reopen the waterway. On March 21, Trump threatened to obliterate Iranian power plants if Tehran did not fully open the strait within 48 hours. As of March 23, Axios reported that Trump had temporarily suspended additional Iran strikes while Hormuz negotiations were underway, with Iranian parliamentary speaker Mohammad Bagher Ghalibaf—now a leading figure given the decapitation of much of Iran's senior leadership—indicating a possible willingness to discuss the strait's status.

But it is the private frustrations of Gulf capitals that may prove most consequential over time. A Bloomberg report published March 27 documented growing alarm among Gulf governments, which are privately questioning American security guarantees and expressing deep concern about what they describe as a lack of coherent US strategy. Gulf officials have watched as their cities burn, their air defense interceptors are depleted at unsustainable rates, and their economies reel—while Washington's messaging has oscillated between threats of obliteration and hints of negotiated tolling arrangements for the strait. This is not the controlled, decisive campaign Gulf states had expected when they quietly acquiesced to the US military buildup on their soil over the preceding year.

The deeper strategic problem is this: the Gulf states are simultaneously dependent on the United States for their defense and exposed to Iranian retaliation precisely because of that dependence. The IRGC's targeting calculus appears designed to make that dependency politically untenable—to drive a wedge between Washington and its Gulf partners by making the cost of hosting American forces prohibitively visible to Gulf populations and leaders alike. Whether it succeeds depends on what happens next in Iran itself. With US and Israeli forces having struck hundreds of targets in at least 26 of Iran's 31 provinces, Iran's ballistic missile production infrastructure, air defenses, naval assets, and leadership apparatus have been significantly degraded. The Islamic Revolutionary Guard Corps remains intact as an institution, however, and hardline elements continue to dominate decision-making in the absence of Supreme Leader Khamenei.

The coming weeks will test whether Iran's remaining missile and drone capacity can sustain the current tempo of attacks against Gulf targets, or whether the US campaign to reopen Hormuz and Secretary of State Marco Rubio's assertion that the operation will conclude in weeks, not months, reflects genuine military reality. For Gulf capitals, the question is more immediate: how long can they absorb incoming fire, deplete their interceptor stocks, and manage civilian anxiety—before the political costs of hosting the United States become greater than the security benefits?
