What locations did naval forces flank along Vietnam war?

During the Vietnam War, U.S. naval forces primarily operated in the coastal regions of South Vietnam, particularly around the Mekong Delta and the Gulf of Tonkin. They conducted operations to interdict supply routes, support ground troops, and provide naval gunfire support. Key locations included the coastal city of Da Nang, the Cu Chi Tunnels near Ho Chi Minh City, and the waters off the coast of North Vietnam, where they engaged in operations like Operation Rolling Thunder. Additionally, naval forces were involved in riverine warfare along the inland waterways, effectively flanking enemy positions.
