Britain has pledged a naval task force including Typhoon fighter jets, autonomous minehunting systems and the destroyer HMS Dragon to a multinational mission to reopen the Strait of Hormuz, the chokepoint through which about a fifth of the world’s oil passes. The announcement, made by Defence Secretary John Healey during a virtual summit of more than forty defence ministers on Tuesday, commits £115 million in new funding for unmanned vessels and anti-drone systems. Healey described the operation as “defensive, independent and credible,” and said it would become operational “when conditions permit.” The government in Canberra confirmed it would contribute a Wedgetail E-7A surveillance aircraft, with Defence Minister Richard Marles leaving open the possibility of sending further assets. From Rome, Defence Minister Guido Crosetto told parliamentary committees that Italy was moving two minehunters from the eastern Mediterranean toward the Red Sea as a precautionary measure, noting that “if peace broke out, it would take allied vessels nearly a month to reach the Gulf.”

The crisis traces back to February 2026, when Iran began imposing restrictions through the strait in retaliation for a joint American-Israeli military campaign that began on 28 February. Viewed from Tehran, the blockade is a lever of asymmetric pressure; from Washington, it is an unacceptable disruption to global energy flows and a test of allied resolve. The multinational response, spearheaded by Britain and France, has drawn pledges from more than forty nations, though many have yet to specify their contributions. Officials in London stress that the mission is strictly defensive and independent of any existing coalition command, a formulation designed to appeal to wary partners who wish to participate without endorsing the original military action that triggered the crisis.

Analysts in London note that the deployment of unmanned minehunters and high-speed drone boats signals a deliberate shift toward low-risk, high-technology assets that can clear the strait without putting large numbers of personnel in harm’s way. The Royal Navy’s HMS Dragon, already transiting toward the region, will provide a visible deterrent. Australia’s Wedgetail aircraft will offer airborne early warning and surveillance, bridging the gap between naval and aerial domains. Italy’s gradual repositioning of minehunters reflects a broader European calculus: prepare to intervene quickly should a diplomatic breakthrough materialise, but avoid escalation while the strait remains contested. Crosetto explicitly framed the move as “preparing to intervene today so we can intervene tomorrow if possible.”

What remains uncertain is the timing of the operation’s activation. The ministerial summit produced a consensus on “collective diplomatic, economic and military capabilities,” but the trigger for commitment remains hazy. Healey’s phrase “when conditions permit” implies a reliance on either a diplomatic opening or a period of reduced hostilities. Meanwhile, Iran continues to control traffic through the strait, and the US-Israel campaign that prompted the closure shows no sign of abating. The success of this multinational effort will hinge not only on the naval assets assembled but on whether the diplomacy that accompanies them can match the military choreography. For now, the alliance is manoeuvring into position, signalling intent without yet engaging—a delicate balancing act between deterrence and provocation.
