NAVCOMMSTA-PWC Diego Garcia was a key United States Navy communications station and Public Works Center located on the island of Diego Garcia in the British Indian Ocean Territory. Established in the early 1970s, it played a vital role in supporting U.S. and allied military operations throughout the Indian Ocean and Persian Gulf regions, particularly during the Cold War and subsequent conflicts. The station provided essential communications, logistics, and engineering support, enabling sustained naval and air operations from this strategic outpost. Over time, its capabilities contributed to the effectiveness of regional power projection and rapid military response in critical situations.

NAVCAMS WESTPAC Guam, or Naval Computer and Telecommunications Area Master Station Western Pacific, Guam, was established to provide critical communications and information systems support to U.S. military forces in the Pacific region. Originating during the Cold War era, the unit evolved from earlier naval communications activities on Guam dating back to World War II, when the island served as a vital strategic hub. Over the decades, NAVCAMS WESTPAC has played a pivotal role in ensuring secure, reliable, and rapid communications for fleet operations, particularly during regional contingencies and humanitarian missions. Today, the unit remains an essential part of the U.S. Navy’s global communications network, supporting both peacetime operations and crisis response in the Indo-Pacific theater.

**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.
