Naval Security Group Vietnam

The Naval Security Group Vietnam (NSG Vietnam) was a specialized unit of the U.S. Navy tasked with signals intelligence (SIGINT) and communications security during the Vietnam War. Established in 1966, NSG Vietnam operated from several sites, including Danang and Saigon, and supported naval operations with critical intelligence on enemy communications and movements. The unit worked closely with other American and allied intelligence organizations, providing real-time information that aided in both tactical and strategic decision-making. NSG Vietnam played an essential role until the U.S. withdrawal, with its mission concluding in 1973 as American forces left South Vietnam.
