I believe Military Ocean Terminal Sunny Point (MOTSU) is also at the Morehead City port.
It is the largest ammunition port in the US.
Sunny Point Ammunition Depot is on the Cape Fear River, near Wilmington, NC. There are two major ports in NC: Morehead City and Wilmington.
MOTSU is on the Cape Fear River, below Wilmington, NC and above Southport, NC on same side of river.
