Overview of the Incident
On March 5, 2026, a US submarine reportedly sank the Iranian frigate IRIS Dena off the coast of Sri Lanka, resulting in the deaths of at least 87 Iranian sailors. The attack, executed with a Mark-48 torpedo, marks the first instance since World War II where a US submarine has fired on an enemy vessel. The IRIS Dena was returning to Iran after participating in naval exercises in India when it was struck approximately 75 kilometers from Galle, Sri Lanka.
Australian Involvement
The Australian government has faced scrutiny regarding the presence of its personnel aboard the US submarine involved in the attack. Foreign Minister Penny Wong has declined to confirm or deny whether Australian sailors were on board, citing operational and security reasons. Reports indicate that between 50 to 100 Australian personnel are currently embedded on US nuclear-powered submarines as part of the AUKUS defense agreement, which aims to prepare Australia for its own nuclear submarine capabilities.
Official Statements & Responses
Wong stated in Parliament, “US submarine operations are a matter for the United States,” emphasizing that specific details about Australian personnel cannot be disclosed for security reasons. This response has drawn criticism from opposition figures, including Greens Senator David Shoebridge, who argued that the lack of transparency regarding military operations undermines democratic accountability. He remarked, “This wall of secrecy is put around every single military operation,” contrasting it with the greater transparency observed in the United States.
Criticism & Opposition
Iran's Foreign Minister, Seyed Abbas Araghchi, condemned the US attack as an "atrocity," warning that the US would "bitterly regret the precedent it has set." Critics within Australia have expressed concern over the government's refusal to clarify the involvement of Australian personnel, suggesting that citizens have a right to know if their country is being drawn into a conflict. Emma Shortis from the Australia Institute noted the historical lack of information sharing by the US with its allies, highlighting the potential implications of Australia's involvement in what she described as an "illegal" war.
Conflicting Reports & Gaps
While some sources claim that two Australian sailors were indeed aboard the submarine during the attack, the Australian Defence Force has not confirmed this information. The Pentagon has not officially identified the submarine involved, though military commentators speculate it may be the USS Minnesota, which had previously docked in Australia.
What's Next
The situation remains fluid, with ongoing discussions in the Australian Parliament regarding military transparency and the implications of the AUKUS agreement. As the conflict escalates, further inquiries into the role of Australian personnel in US military operations are anticipated.
