NCTS Yokosuka Menu


U.S. Naval Computer and Telecommunications Station (NCTS) Far East was originally designated as Naval Communications Facility, Yokosuka Japan and was commissioned on 8 January 1951 after the outbreak of the Korean Conflict. In December 1952, U.S. Naval Radio Receiving Facility, Kami Seya, Japan was completed and the Security Group Department and general service receivers were moved to Kami Seya. During the Korean Conflict, the rest of NAVCOMMFAC Yokosuka moved to Kami Seya. In 1960, the command was redesignated U.S. Naval Communications Facility Japan and relocated to Yokosuka Japan. The following year, the command was again redesignated as U.S. Naval Communications Station, Japan. This name stood for 30 years until 1991, when it was changed to U.S. Naval Computer and Telecommunications Station, Japan to acknowledge the increasing reliance on computers and telephones in telecommunications. Also in 1991, NTCCs Atsugi and Sasebo and NAVCOMM Dets Okinawa and Misawa were functionally transferred to NAVCOMTELSTA Japan. 1993 saw the transfer of Base Communications Offices (BCOs) at Atsugi, Sasebo and Yokosuka to NAVCOMTELSTA Japan. Then in 1995, another name change to U.S. Naval Computer and Telecommunications Station, Far East occurred with the functional transfer of the Communications Department from Commander Fleet Activities Chinhae, Korea to this command and the establishment of NAVCOMM Det Chinhae. The Headquarters, Naval Telecommunications Center, Technical Control Facility and BCO are located in Yokosuka , where NAVCOMTELSTA Far East is a tenant of the Commander Fleet Activities Yokosuka.

Originally, naval communications on Okinawa was provided by a Naval Communication Station located on Futenma Marine Base. The NAVCOMMSTA relocated to the Navy Air Base, Naha City and became a department of the Naval Air Facility, Naha. In May 1972, NAF Naha was combined with Fleet Activities Okinawa. In 1975, the Naha base was disestablished and all naval facilities were relocated to Kadena Air Base becoming Commander, Fleet Activities Okinawa. During the same period, the Anti-Submarine Warfare Communications Center (ASCOMM) Department, an integral part of the Anti-Submarine Warfare Operations Center (ASWOC) of FAIRWING ONE DET NAHA, also relocated from Naha to Kadena. Naval Radio Transmitting Facility Awase, originally an Army/Air Force communications site, was transferred to the Navy in 1966 and eventually became part of Commander Fleet Activities Okinawa Communications Department. NAVCOMM Det Okinawa was established and joined the NAVCOMTELSTA team in February 1991. NAVCOMM Det Okinawa consists of Tactical Support Center Communications (TSCCOMM) Division, COMSEC Material System (CMS) Division, Naval Radio Transmitter Facility (NRTF) Awase, and Surveillance Towed Array Sensor System (SURTASS) Division.

ATSUGI U.S. Naval Telecommunications Center (NTCC) Atsugi, Japan was commissioned in February 1991 as a part of NAVCOMTELSTA Japan. NTCC provided messaging support to customers on board U.S. Naval Air Facility Atsugi until being disestablished in 1994. In 1993, responsibility for Base Communications Office (BCO) Atsugi transferred from NAF Atsugi Public Works Department to NAVCOMTELSTA Japan, N2 Department, to improve support for business and residential base telecommunications services for NAF Atsugi. In 2005, the NAF Atsugi ADP office transferred to NAVCOMTELSTA Far East as part of N4 Department and eventually became known as Local Network Service Center (LNSC) Atsugi. LNSC provides host services, materials, and IT support to NAF Atsugi, and Commander, Carrier Air Wing 5 (CVW-5), as well as other tenant commands and transient squadrons and detachments. In March 2009, NAVCOMTELSTA FAR EAST DET ATSUGI was officially established, consisting of the LNSC and BCO, to provide support for increased local communications requirements on board NAF Atsugi.
