Spain has officially barred US military aircraft involved in the ongoing conflict with Iran from entering its airspace, forcing American bombers to drastically alter their flight paths.
Spanish Defence Minister Margarita Robles confirmed the decisive move, explicitly barring the US from utilizing the jointly operated military installations in Andalusia.
"We will not authorise the use of Morón and Rota for any acts related to the war in Iran," Robles stated, emphasizing that the Spanish government had communicated this red line to Washington from the very beginning of the hostilities.
Foreign Affairs Minister José Manuel Albares echoed this sentiment, explaining that Madrid is determined to avoid any actions that could further escalate the Middle Eastern conflict.
Since the outbreak of the war in late February, Spanish Prime Minister Pedro Sánchez has emerged as a fierce critic of the US and Israeli strikes against Iran, labeling the military campaign "reckless" and "illegal." Earlier this month, Sánchez revealed that Madrid had systematically denied all flight plans associated with the Iranian operation, including requests for mid-air refueling.
"We are a sovereign country that does not wish to take part in illegal wars," Sánchez announced.
The White House has publicly brushed off the restrictions. An official claimed that the US military is already "meeting or surpassing all of its goals under Operation Epic Fury" and does not require assistance from Spain. However, the diplomatic rift has drawn fierce backlash from US President Donald Trump, who has threatened to hit Spain with a comprehensive trade embargo for refusing to cooperate.
Logistically, the airspace ban complicates routes for US bombers operating out of RAF Fairford in the UK—a base made available after British Prime Minister Sir Keir Starmer approved Washington's request. To avoid Spanish territory, these warplanes must now bypass the Iberian Peninsula entirely, flying instead over France or the eastern Atlantic Ocean. According to reports from the Spanish daily El País, US military aircraft will only be permitted to enter Spanish airspace or land at its bases in the event of a critical emergency.
Meanwhile, Madrid's staunch anti-war posture—which Sánchez recently likened to the country's historical opposition to the Iraq War—has fostered unexpected diplomatic goodwill with Tehran. The Iranian embassy in Spain recently signaled that it would look favorably upon any requests from Madrid regarding transit through the highly contested Strait of Hormuz, citing Spain's "commitment to international law."
The narrow strait, a crucial maritime chokepoint that normally facilitates 20% of the global oil supply, has been effectively shut down for weeks due to the looming threat of Iranian drones, missiles, and naval mines. The resulting blockade has sent global oil markets into a frenzy, triggering sharp spikes in fuel prices.
