Iran Air Flight 655 (IR655) was a civilian jet airliner shot down by U.S. missiles on 3 July 1988, over the Strait of Hormuz, toward the end of the Iran–Iraq War. The aircraft, an Airbus A300B2-203 operated by Iran Air, was flying from Bandar Abbas, Iran, to Dubai, United Arab Emirates, when it was destroyed by the U.S. Navy's guided missile cruiser USS Vincennes, killing all 290 passengers and crew aboard, including 66 children,ranking it ninth among the deadliest disasters in aviation history

It was the highest death toll of any aviation incident in the Indian Ocean and the highest death toll of any incident involving an Airbus A300 anywhere in the world. Vincennes was traversing the Strait of Hormuz, inside Iranian territorial waters, and at the time of the attack IR655 was within Iranian airspace

However, the United States has never admitted responsibility, nor apologized to Iran
