The Navy Information Operations Command (NIOC), Hawaii (previously: Naval Security Group Activity (NSGA) Hawaii, NSGA Kunia, and NSGA Pearl Harbor) is a United States naval installation located on the Hawaiian island of Oahu. NIOC Hawaii employs more than 2,000 sailors and civilians in support of cyber operations and signals intelligence ("SIGINT").[1] It was originally formed on 30 September 2004, after the merging of NSGA Kunia and NSGA Pearl Harbor, and then known as the combined "NSGA Hawaii". NIOC Hawaii serves as a worldwide hub for a secure US and allied communications network. NIOC Hawaii also provides a secure radio relay, as well as support to the US Indo-Pacific Command ("USINDOPACOM") by providing cryptologic personnel, as well as information, communications, and engineering installation services. NIOC Hawaii provides host support services to the Regional Security Operations Center.[2]
