About this Unit
Naval Communications Station (NAVCOMSTA) Yokosuka, Japan, was established in the early 1950s to support U.S. Navy operations in the Western Pacific following World War II. Strategically located within the U.S. Fleet Activities Yokosuka complex, the unit provided critical communications, cryptographic, and electronic support for naval and joint forces throughout the region. NAVCOMSTA Yokosuka played a vital role during the Korean and Vietnam Wars, ensuring reliable command and control links between deployed fleets and higher headquarters. Over time, its mission evolved with advances in technology, and the station eventually transitioned into what is known today as the Naval Computer and Telecommunications Station (NCTS) Far East.
