Small Ships, Big Stakes: The EU’s Aspides Mission Faces Its Greatest Test

The EU’s Aspides naval mission — just three ships from France, Italy, and Greece — is facing the greatest test of its relevance and effectiveness as the Strait of Hormuz crisis escalates and European ministers debate whether to expand its mandate to cover the Persian Gulf. The mission was originally designed to protect commercial shipping from Houthi drone and missile attacks in the Red Sea, and it is now being considered as a vehicle for responding to a far more dangerous crisis in a different body of water. Germany’s foreign minister has already declared the mission ineffective, raising fundamental questions about whether it is fit for purpose in its current form, let alone whether expanding it makes strategic sense.
Iran’s blockade of the Hormuz strait has generated the worst oil supply disruption in history, cutting off one-fifth of global oil exports since late February when Tehran retaliated for US-Israeli airstrikes. The situation is categorically more dangerous than the Houthi threat the Aspides mission was designed to address. Iran’s military capabilities are significantly greater than those of the Houthi rebels, Tehran has explicitly threatened to destroy vessels heading for allied ports, sixteen tankers have been attacked, and the prospect of mine warfare in the strait adds a lethal dimension that the mission’s current composition would be ill-equipped to address.
President Trump called on EU members among others to send warships to the strait, with France — an Aspides participant — refusing outright while fighting continued. French Defence Minister Catherine Vautrin ruled out any deployment during active hostilities and confirmed the Charles de Gaulle aircraft carrier would remain in the eastern Mediterranean. The other Aspides participants — Italy and Greece — have not made independent statements about sending additional vessels to the Hormuz area. EU foreign ministers are reportedly examining the possibility of expanding the mission, but Germany’s explicit scepticism creates a significant obstacle to building the consensus needed for any such decision.
The fundamental problem with proposing Aspides as the vehicle for a Hormuz response is one of scale and capability. Three ships designed to intercept Houthi drones and missiles in the Red Sea would face a qualitatively different threat environment in the Strait of Hormuz, where Iran’s naval forces, missile batteries, attack vessels, and mining capability represent a far more sophisticated and lethal threat. Providing meaningful escort protection in the strait would require a significantly larger and differently configured force than the current Aspides mission can provide, even if all member states agreed to expand its mandate.
China’s approach to the crisis — quiet diplomacy rather than naval force — may ultimately be more consequential than any EU naval deliberation. Beijing is reportedly in discussions with Tehran about allowing oil tankers to pass, a process that could provide partial relief without requiring the military capabilities and political will that the Aspides expansion debate reveals are in short supply. The Chinese embassy confirmed China’s commitment to constructive regional engagement. US Energy Secretary Chris Wright expressed hope that China would prove a constructive partner, acknowledging active dialogue with multiple nations was underway as the world searches for a workable path through the crisis.
