Also known as NCTAMS PAC, the Naval Computer and Telecommunications Area Master Station Pacific provides operation direction and management to Naval telecommunications users in the Pacific. On top of this, the facility also manages and operates Naval Telecommunication System and Defense Communication System assets. It works in conjunction with the US Department of Defense, the US Navy, and many other federal organizations.
NCTAMS PAC has been active since 1906. It is located in Wahiawa, Hawaii. It was used heavily during World War 2, after the US Pacific Fleets were moved to Pearl Harbor to help the war effort. With so many boats in dock, it became obvious that a telecommunications command center would be necessary. During the war, there were several communications facilities in Wahiawa and the surrounding area. After the war ended, an appointed committee decided that the systems should be condensed into a single base, so they combined them all into Naval Communications Station Honolulu, which was later renamed Naval Computer and Telecommunications Area Master Station Pacific, or NCTAMS PAC, the modern name for the station.
