An unarmed Iranian navy Bell 212 helicopter flew alongside the Boxer, yards away from the deck, before it was chased away by a U.S. helicopter. The commander of the Boxer, Capt. Ronald Dowdell, called the engagement “surreal.”
The convoy swept past the speed boats without incident but was followed by the larger Iranian military vessel, which came as close as 500 yards to the Boxer—the distance the U.S. navy allows before verbally communicating to a ship not to come any closer.
U.S. helicopters flew between the Iranian ship and the Boxer to warn it away, then followed a white Iranian aircraft that U.S. naval officials identified as a Y-12 surveillance plane.
Soon after, at approximately 10 a.m. local time, the Boxer convoy downed the drone, a U.S. official said late Thursday.
