The ongoing US-Israel-Iran conflict has escalated dramatically into naval warfare, with Washington confirming strikes on over 30 Iranian vessels across the Persian Gulf, Strait of Hormuz, Gulf of Oman, and now the Indian Ocean. This expansion of the battlefield underscores rising tensions in vital maritime routes, threatening global shipping and energy supplies. US Defense Secretary Pete Hegseth announced the operations, which involve submarine torpedoes, carrier-based airstrikes, and drone ᴀssaults aimed at neutralizing Iran’s naval ᴀssets and disrupting its ability to project power.
The campaign intensified on March 4, 2026, when a US submarine torpedoed and sank the Iranian frigate IRIS Dena in international waters off Sri Lanka, killing at least 104 crew members and leaving dozens missing. The vessel had just completed joint naval exercises with India, prompting international outcry and straining US-India relations, as New Delhi accused Washington of disregarding its sovereignty and regional stability.
This marked the first warship sinking by torpedo since World War II, highlighting the conflict’s shift to asymmetric naval engagements far from the Middle East.
US forces have since targeted additional Iranian ᴀssets, including over 10 mine-laying boats near the Strait of Hormuz and warships in the Gulf of Oman. President Donald Trump has boasted that the US is “annihilating Iran’s navy,” with the USS Abraham Lincoln carrier strike group playing a central role in the ᴀssaults. Iranian officials, however, claim successful counterstrikes, including ballistic and cruise missile hits on a US destroyer and supply ship in the Indian Ocean, causing fires and forcing American vessels to retreat southward. The Islamic Revolutionary Guard Corps (IRGC) reported striking strategic US targets 600-650 km deep in the Indian Ocean.
As of March 12, 2026, the war enters its 14th day, with naval clashes continuing amid broader air and missile exchanges. Iran has bombarded the US 5th Fleet headquarters in Bahrain and launched Kheybar Shekan missiles at Israeli targets. Proxies like the Houthis have disrupted Red Sea shipping, while the Indian Ocean incidents involve recent Iranian transits post-Indian drills, raising concerns of third-party involvement.
Reports suggest Chinese satellite support for Iranian operations, potentially complicating the geopolitics.
Casualties are rising, with over 1,000 deaths reported in Iran from initial strikes, plus naval losses. US public opinion is divided, with many questioning the war’s necessity amid midterm elections. Oil prices have spiked, and shipping routes are under threat, prompting calls for de-escalation from neutral nations like India, whose Prime Minister Narendra Modi faces domestic pressure over the incident.
Iranian leaders vow a prolonged response, contrasting with Trump’s claims of imminent victory. As tensions boil in the Indian Ocean, the risk of a wider regional or global confrontation looms, with diplomatic efforts frozen and military actions showing no signs of abating.
