A vessel from Iran's Islamic Revolutionary Guard Corps came within 100 yards of a U.S. military ship in the central Gulf on Sept. 4, two U.S. Defense Department officials told Reuters on Tuesday.
The officials, speaking on the condition of anonymity, said the Iranian vessel sailed directly in front of the USS Firebolt, a 174-foot (53 m) coastal patrol vessel, forcing the U.S. ship to change course in a maneuver they described as "unsafe and unprofessional."
