At 2:40 a.m., alarms screamed aboard a US destroyer escorting a carrier strike group in the Arabian Sea as radar picked up the nightmare scenario: five Iranian hypersonic missiles inbound at blistering speed, streaking low and weaving through electronic jamming.

Combat systems officers slammed the ship into full defence mode. SM‑6 interceptors and close‑in weapons lit up the night, scoring multiple kills in seconds. But one warhead exploded dangerously close off the port bow, ripping shrapnel across the superstructure, starting fires and injuring several sailors. The carrier behind it stayed untouched – but the message from Tehran was unmistakable.

Within minutes, the US answer came — and it was uncompromising. A pre‑planned response package snapped into action: submarine‑launched cruise missiles, B‑52 and B‑2 strikes, and carrier‑borne jets hammering the very launch complexes that had fired the hypersonics, along with coastal radar, command bunkers and IRGC missile brigades. Satellite images later showed scorched pads, collapsed tunnels and burning fuel depots along Iran’s coast.

Tehran claimed a “strategic victory” for breaching US defences; Washington called the near‑miss proof the shield works and the blistering retaliation a warning that any strike on a US warship will draw instant, devastating fire.

As dawn broke over a smoking coastline and a damaged but still‑afloat destroyer, one reality settled on capitals worldwide: the age of hypersonic warfare has arrived — and with it, a hair‑trigger duel where minutes, even seconds, can decide whether a crisis is contained or spirals into full‑scale war at sea.
