Iris Dena Sinks Following US Submarine Attack
In a significant military incident, the Iranian warship Iris Dena sank approximately 40 kilometers off the southern coast of Sri Lanka on March 4, 2026, after being struck by a torpedo from a US submarine. The attack has raised serious concerns regarding escalating tensions in the region, particularly between the United States and Iran.
The Iris Dena had been returning from the 2026 International Fleet Review in India and was reported to have around 180 crew members on board at the time of the incident. A distress call was sent out between 6 AM and 7 AM, shortly before the ship sank. Sri Lanka’s navy has since recovered 87 bodies and rescued 32 sailors from the sea, highlighting the tragic human cost of this military engagement.
This incident marks the first US attack on an Iranian military vessel outside the Middle East since the onset of the ongoing conflict. According to reports, the Iris Dena was equipped with advanced weaponry, including surface-to-air missiles, anti-ship missiles, cannons, machine guns, and torpedo launchers. However, it appears that the ship’s defense and counterattack capabilities were neutralized by electromagnetic means prior to the torpedo strike.
Commenting on the event, military analyst Pete Hegseth stated, “An American submarine sunk an Iranian warship that thought it was safe in international waters.” He further noted the significance of the attack, saying, “It was sunk by a torpedo, a quiet death – the first sinking of an enemy ship by a torpedo since World War II.” This statement underscores the gravity of the situation and the potential shift in military strategies being employed in the region.
The sinking of the Iris Dena occurred amid escalating hostilities between the US, Israel, and Iran, with recent air strikes conducted by the US and Israel on Iranian targets over a span of five days. The exact circumstances leading to the sinking of the Iris Dena remain unclear, and details surrounding the Iranian government’s official response to the incident have not been confirmed.
As the situation develops, the international community is closely monitoring the implications of this incident for regional stability. The sinking of the Iris Dena not only represents a significant military engagement but also raises questions about the future of naval operations in international waters.
While the immediate aftermath has seen a tragic loss of life, the broader geopolitical ramifications of this event are yet to unfold. The incident serves as a stark reminder of the fragile nature of peace in the region and the potential for further escalation in military confrontations.
