Naval Communication Station Guam (NAVCOMMSTA Guam) was established in 1944 following the liberation of Guam during World War II, serving as a vital communications hub for the U.S. Navy in the Pacific. Throughout the Cold War, the station played a crucial role in long-range radio communications, supporting both fleet operations and strategic command-and-control functions across the Pacific theater. NAVCOMMSTA Guam was notable for operating powerful transmitters and large antenna arrays, including the iconic AN/FRD-10 Circularly Disposed Antenna Array. In 1997, the command was reorganized and its functions integrated into Naval Computer and Telecommunications Station (NCTS) Guam, continuing its mission of providing secure communications support to U.S. and allied forces in the region.

Naval Security Group Activity (NSGA) Winter Harbor, Maine, was established in 1935 on the Schoodic Peninsula as a United States Navy radio intercept and direction-finding station. Originally part of the Navy's growing network of signals intelligence (SIGINT) sites, NSGA Winter Harbor played a crucial role during World War II and the Cold War, tracking enemy communications and supporting national security efforts. The facility operated advanced radio and cryptologic equipment, contributing vital intelligence for fleet and national decision-makers. NSGA Winter Harbor was decommissioned in 2002, with its property later transferred to the National Park Service to become part of Acadia National Park.

**SISS ZULU** was a US Navy Shore Intercept Site located at Zeto Point on Adak Island, Alaska, established during the Cold War. The site was part of the larger Adak Naval Complex and operated under the Naval Security Group, with the mission of signals intelligence (SIGINT) collection and monitoring Soviet military activity in the North Pacific region. Known as “ZULU Site,” the facility played a crucial role in electronic surveillance, support of fleet operations, and early warning during periods of heightened tension with the Soviet Union. SISS ZULU was decommissioned in the 1990s as geopolitical circumstances changed and technology advanced, but it remains a testament to the strategic importance of Adak in US military history.
