Australia Withholds Details on Crew Amid US Submarine Attack on Iranian Warship
The Australian government has declined to reveal whether any Australian sailors or officers were present onboard a United States attack submarine that launched a torpedo, sinking an Iranian warship in the Indian Ocean. The incident resulted in the deaths of at least 87 individuals, marking a significant escalation in regional tensions.
Training Under Aukus Raises Questions
More than 50 Australian sailors and officers are currently serving across the US attack submarine fleet as part of a comprehensive training regimen. This initiative is a key component of preparations for Australia to command its own nuclear-powered submarines under the Aukus security pact. According to the Royal Australian Navy, approximately one in ten crew members on US Navy attack submarines is Australian, with defence sources suggesting two Australians may have been onboard during the attack.
If confirmed, this would represent the first direct involvement of Australian defence personnel in the ongoing conflict. Foreign Minister Penny Wong addressed the Senate, stating that US submarine operations are solely a matter for the US Navy. She emphasised, "For operational and security reasons, we don’t disclose specific information regarding Australian personnel."
Historic US Strike and Iranian Response
The US submarine strike targeted the Islamic Republic of Iran Ship (Iris) Dena, a frigate sailing in international waters off the coast of Galle, Sri Lanka. US Secretary of War Pete Hegseth described the attack as the first sinking of an enemy vessel by an American torpedo since World War II, calling it "a quiet death." Hegseth vowed "sheer destruction" for Iran, following the assassination of Supreme Leader Ayatollah Ali Khamenei, asserting, "America is winning decisively, devastatingly and without mercy."
While the Pentagon has not officially identified the submarine involved, defence trade press reports indicate it was the USS Minnesota, a Virginia-class submarine that previously docked at HMAS Stirling in Western Australia. The Iranian frigate was carrying up to 180 personnel and had recently participated in a naval exercise organised by India in the Bay of Bengal.
Secrecy and Democratic Concerns
Emma Shortis, Director of International and Security Affairs at the Australia Institute, expressed that it is "highly likely" an Australian citizen was part of the crew. She criticised the secrecy surrounding the Aukus deal, noting, "In a democracy, the Australian people have a right to know if Australia is being dragged into any war, let alone one that is so transparently illegal like this one." Shortis highlighted concerns that the Australian government may not have had advance warning of the attack, reflecting a pattern of limited information sharing by the US with allies.
In Parliament, Greens Senator David Shoebridge questioned Wong about Australian personnel onboard during the strike, but received no confirmation. The defence minister, Richard Marles, has previously underscored the close collaboration between Australia and the US, with nearly 900 Australian service members embedded in US defence forces.
Regional Military Movements
Adding to the complexity, two US P-8A Poseidon maritime patrol aircraft recently arrived at RAAF Base Pearce in Perth, having flown from Diego Garcia in the Indian Ocean. Their mission remains undisclosed by both Australian and US militaries, though these aircraft are capable of reconnaissance and torpedo launches. This development underscores the heightened military activity in the Indo-Pacific region, where the US Indo-Pacific Command, headquartered in Hawaii, oversees operations.
Iranian Foreign Minister Seyed Abbas Araghchi condemned the US attack as an "atrocity" committed far from Iranian shores, warning that the US will "bitterly regret the precedent it has set." As investigations continue, the lack of transparency from Australian authorities leaves critical questions unanswered regarding national involvement and the implications for regional stability.
