Vietnam War Commemoration Commission

Week of March 19

In late February 1965, a U.S. helicopter pilot spotted a 130-foot North Vietnamese vessel anchored in South Vietnam's Vũng Rô Bay. Investigators discovered the ship was carrying arms, ammunition, and other war materiel intended for the Việt Cộng. By March 1965, the Vũng Rô Bay incident led to the start of Operation MARKET TIME and the establishment of the U.S. Coastal Surveillance Force (Task Force 115). The task force's mission was to halt Communist infiltration of South Vietnam by sea.

Operation MARKET TIME lasted for seven years. During that time, U.S. Navy and Coast Guard vessels and aircraft of Task Force 115 patrolled 1,200 miles of South Vietnam's coastline from the Demilitarized Zone to the Cambodian border. They intercepted enemy vessels, searched junks, sampans, and other watercraft suspected of supplying the Việt Cộng, transported allied troops, and evacuated refugees.

MARKET TIME and Task Force 115 were highly successful at curbing Communist seaborne infiltration of South Vietnam. American participation in MARKET TIME lasted until 1971, when the United States transferred responsibility for the operation to the South Vietnamese Navy.1
