In 1957, the Naval Security Group (NSG) established the Communication Security (COMSEC) Mobile Support Unit 9 at Sasebo, Japan. In December of the same year, NSG established and commissioned the Naval Security Group Detachment (NSGD) Sasebo.
Initially the only mission for NSGD Sasebo was a high frequency direction finding (HFDF) operation with 11 personnel, including eight DF operators. The site operated as part of the NSG’s Western Pacific (WESTPAC) HFDF network controlled from U.S. Naval Communications Facility Kami Seya (A). Initially, it was considered a temporary site until the NSG Activity at Hakata assumed Sasebo’s HFDF mission.
The site was equipped with an AN/TRD-4 transportable DF station with a frequency range 540 kHz to 30 MHz. The antenna system consisted of two separate four element Adcock arrays, one of which had a range from 540 kHz to 10 MHZ and the other from 10 to 30 MHz. The DF receiver system included an R-390/URR HF radio communications receiver.

..."Sasebo Naval Base
U.S. Fleet Activities Sasebo provided heavy support to the expanded Seventh Fleet during the years of war in Southeast Asia. Repair work completed by Japanese shipyards in Sasebo was then, and is still today, equal to the best in the world. Operations at U.S. Fleet Activities Sasebo were scaled back during the mid-1970s and the base was designated as a Naval Ordnance Facility, while fleet visits dwindled to a very low level.
On July 4, 1980 this trend was reversed. U.S. Fleet Activities Sasebo regained its name and once again, Seventh Fleet ships were forward deployed to Sasebo. U.S. Fleet Activities Sasebo is currently home to USS Bonhomme Richard (LHD 6), USS Ashland (LSD 48), USS Germantown (LSD 42), USS Green Bay (LPD 20), USS Warrior (MCM 10), USS Patriot (MCM 7), USS Pioneer (MCM 9), USS Chief (MCM 14) and some 5,900 military members and their families as part of the Forward Deployed Naval Forces.
U.S. Fleet Activities Sasebo played a vital logistics role in 1990-91 during Operation Desert Shield/Storm by serving as a supply point for ordnance and fuel for ships and Marines operating in the Persian Gulf theater.
Sasebo today
Today, as throughout its history, U.S. Fleet Activities Sasebo stands ready to support Seventh Fleet units as they continue to ensure peace and security in the Pacific region."
