The major American troop buildup between 1965 and 1968 required massive logistical resources. By 1968, almost 45 percent of all American military
personnel in South Vietnam were support troops, and more than five million tons of goods were shipped into the country. Because of insufficient port
facilities, American merchant ships in 1965 typically had a twenty-day waiting period to be unloaded. To eliminate that backlog, the United States constructed
major deep-water ports at Cam Ranh Bay, Da Nang, Qui Nhon, and Newport, near Saigon. The port at Newport just outside Saigon relieved the congestion
there after its construction was completed in 1967. Newport handled more than 150,000 tons of supplies each month. It was under the control of the
army transportation corps.
