An Offshore Heavy Transport ship came into port too quickly, leading to a crash causing millions in damage to a US Navy warship, safety investigators have determined.

The National Transportation Safety Board (NTSB) said in a report Tuesday that the 64,900-dwt Hawk (built 1989) was travelling too fast as it neared the Huntington Ingalls Shipyard in Pascagoula, Mississippi 29 March 2019 before colliding with a docked barge and the USS Delbert D Black.
