John Kirby said there was no indication whether the dhow was struck.The Navy statement said the dhow crew did not respond when fired upon and left the scene without communicating with the Monomoy.Earlier, the Monomoy had established communication with the dhow and determined that it was an Iranian-flagged vessel, the Navy said, adding that it subsequently refused to communicate further.No U.S. personnel were harmed and the small boat's crew returned safely to the Monomoy, the Navy statement said.The Coast Guard is in the gulf operating with the Navy's Fifth Fleet.Marines test new beach assault vehicle'Aggressive' Chinese fighter jet flies dangerously close to U.S. Navy planeU.S. militaryArmy to launch 'blimp' that detects cruise missilesThe U.S. Army plans to launch two stationary "blimps" at 10,000-feet in the air next week to better protect the Washington D.C. area from cruise missiles and other possible air attacks.
