Australia joins UK-France naval mission to secure Strait of Hormuz

France, UK and Australia Advance Multinational Mission to Secure Strait of Hormuz

The United Kingdom and France hosted a multinational meeting of defense ministers on Tuesday to advance plans for a naval mission to protect commercial shipping in the Strait of Hormuz, as Australia confirmed it would join the effort and Britain deployed a warship to the region.

UK Defence Secretary John Healey and French Armed Forces Minister Catherine Vautrin co-chaired the virtual meeting, which brought together representatives from more than 40 countries to discuss military contributions to the European-led coalition. The talks came as Iran issued sharp warnings against any foreign naval presence in the waterway.bloomberg

A Coalition Takes Shape

The mission traces its origins to an April 17 summit in Paris, where French President Emmanuel Macron and British Prime Minister Keir Starmer convened 51 countries and announced the establishment of “an independent and strictly defensive multinational mission to protect merchant vessels, reassure commercial shipping operators and conduct mine clearance operations”. More than a dozen countries offered to contribute assets at the time, with Starmer pledging a military planning conference in London the following week.gouv

That planning has now accelerated. Countries attending Tuesday’s meeting were expected to outline contributions including demining, vessel escort and air policing capabilities. The UK announced that HMS Dragon, a Type 45 air-defense destroyer, would deploy to the Middle East to pre-position for the mission. “The pre-positioning of Dragon is part of prudent planning that will ensure the UK is ready, as part of a multinational coalition jointly led by the UK and France, to secure the Strait, when conditions allow,” a UK Ministry of Defence spokesperson said.navalnews

Australia’s Defence Minister Richard Marles confirmed on Wednesday that Canberra would join the coalition, pledging an E-7A Wedgetail surveillance aircraft already operating in the region. “Australia stands ready to support an independent and strictly defensive Multinational Military Mission, led by the United Kingdom and France, once it is established,” Marles said in a statement.iranintl

Iran’s Warning and the Road Ahead

The initiative has drawn a forceful response from Tehran. Iran’s Deputy Foreign Minister Kazem Gharibabadi warned on X that any deployment of French and British warships near the strait “will be met with a decisive and immediate response by Iran’s armed forces”.iranintl

The strait, through which roughly one-fifth of the world’s oil passes, has been a focal point of the broader Middle East conflict. Iran has used control of the waterway as leverage in ceasefire negotiations with the United States, and while Tehran announced a conditional reopening of the strait in April, the terms remain contested. The coalition has emphasized that the mission would only become operational following a sustainable ceasefire, and that it is separate from the belligerents in the ongoing conflict.thedefensepost

Diplomatic Tightrope

Organizers have been careful to frame the mission as independent from American and Israeli military operations. Macron stressed in April that the coalition represented “independent States separate from the ongoing hostilities,” while pledging close diplomatic coordination with Washington and regional players. The distinction is critical: participating nations have argued that joining the existing U.S.-led blockade of Iranian shipping would amount to entering the war, whereas a post-ceasefire escort mission falls under established principles of freedom of navigation.straitstimes

With negotiations between Iran and the United States still facing gaps over uranium stockpiles, sanctions relief and the scope of a ceasefire, the timeline for activating the mission remains uncertain. For now, the coalition is positioning assets and building the military architecture to act when the moment comes.euronews
