Background

The International Fleet Review 2026 was a multinational naval ceremonial event hosted by India at Visakhapatnam, its principal eastern naval base. Fleet reviews assemble warships from invited nations for inspection, combining diplomatic symbolism with a display of naval capability. India last hosted the event in 2016, establishing it as a recurring instrument of Indo-Pacific maritime diplomacy.

The 2026 review ran concurrently with Exercise MILAN at Visakhapatnam. Among the attending vessels was IRIS Dena, an Iranian frigate that departed after the review and was transiting home when the Iran conflict erupted. She was sunk by a US submarine torpedo, the first such kill since 1945. At least 80 crew were killed.

Iran's participation placed a warship FAR from home at the moment hostilities began, leaving her isolated and defenceless in open ocean. Having hosted Iranian naval officers weeks before the US sank their ship, India now faces pressure to clarify its stance in a conflict unfolding within its regional sphere.

How the World Sees Them

Iran

Iran sent IRIS Dena to the IFR as a signal of its naval reach and diplomatic engagement in the Indo-Pacific. The frigate's subsequent destruction in open ocean transformed a goodwill visit into a stark demonstration of its fleet's vulnerability.

India

India has hosted fleet reviews as a platform for Indo-Pacific maritime diplomacy, welcoming navies from across the region. The presence of an Iranian warship at Visakhapatnam weeks before the US sank her has complicated New Delhi's neutral posture in the Iran conflict.

Sri Lanka

Sri Lanka's territorial waters became the scene of multiple Iranian naval casualties in the early conflict, including the loss of IRIS Dena and the internment of IRIS Bushehr, drawing a non-aligned nation into the conflict's maritime aftermath.

United States

Washington views Iranian naval deployments as power-projection exercises warranting close surveillance. The torpedo sinking of IRIS Dena as she transited home from the IFR signalled that the US was tracking Iranian vessels throughout their deployment.
