About this Unit
**NCS ADAK (Naval Communications Station Adak)** was established on Adak Island in the Aleutian Islands, Alaska, during World War II. Originally built as a critical communications and logistics hub for U.S. Navy operations in the North Pacific, NCS ADAK played a vital role in supporting the Aleutian Islands Campaign against Japanese forces. During the Cold War, the station expanded its mission, providing advanced communications, electronic surveillance, and intelligence support as part of the broader U.S. defense posture against the Soviet Union. The station was decommissioned in 1997 following the post-Cold War military drawdown, marking the end of more than five decades of strategic service.
