A HC-130 Hercules airplane crew from Barbers Point is searching for the captain of a freighter who reportedly fell overboard 2,300 miles west of Honolulu.
The Joint Rescue Coordination Center were notified at about 6 p.m. Saturday that a 49-year-old Polish national was reported overboard from the 622-foot freighter Toscana.
The man was last seen at 8 p.m. Friday.
Twelve hours passed before the crew realized he was missing.
The Hercules was launched Saturday and is staging out of Wake Island to conduct the searches.
The ship retraced its route to search for the missing crewmember about 60 miles east of Wake, but has continued on to its next port of call in Yokohama, Japan, due to fuel limitations, the Coast Guard said.
The Coast Guard is looking for other vessels in the area that could help with the search.
Winds in the area are about 15 mph, with seas of 8 feet and a water temperature of about 81 degrees, the service said.
