SISS ZULU Zeto Point, Adak

**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.
