The Pentagon is hailing a “historic naval victory” tonight after a U.S. fast‑attack submarine reportedly sank an Iranian warship with heavyweight torpedoes in the Arabian Sea — a strike officials are dramatically branding the “first torpedo kill since World War II.”

According to U.S. defense sources, the Iranian vessel had been shadowing commercial shipping and allegedly locking fire‑control radar onto American escorts. After repeated warnings, the submerged U.S. sub fired a pair of torpedoes that ripped open the warship’s hull, leaving it burning and sinking within minutes. Search‑and‑rescue craft are now scouring the area for survivors.

Hours later, chaos spread to the Strait of Hormuz, where a major oil tanker was hit by what investigators suspect was an Iranian mine or anti‑ship missile. Flames and thick black smoke billowed from the vessel as crew issued a mayday, forcing dozens of nearby ships to alter course and triggering a spike in global oil prices.

Washington accuses Tehran of “state‑sponsored piracy,” vowing that any further attacks on shipping will meet “overwhelming force.” Iran’s Revolutionary Guard, in turn, calls the torpedo strike a “cowardly ambush,” promising retaliation against U.S. assets “from the Gulf to the Mediterranean.”

With a sunken warship, a crippled tanker, and warships from multiple nations racing into the world’s most critical chokepoint, analysts warn that the line between deterrence and all‑out naval war has never been thinner.
