Kunia Regional SIGINT Operations Center



The Kunia Regional SIGINT Operations Center (KRSOC, also pronounced "KR-Sock"), also known as the Kunia Tunnel or the Regional Signals Intelligence Operations Center Kunia, is a United States National Security Agency facility. It is a secured installation located on Kunia Road between Kunia Camp and Wheeler Army Airfield in central Oahu, Hawaii.

History
In response to the attack on Pearl Harbor in 1941, the installation was designed and built as a bomb-proof, underground open bay with a 250000 sqft floorspace to facilitate aircraft assembly in proximity to Wheeler Army Airfield. During the later part of World War II and in the decades that followed it was used primarily for cryptologic and intelligence activities.

In May 2013, a worker at the facility, Edward Snowden, loaded classified documents onto a memory stick and provided the documents to the press, revealing the existence of NSA mass surveillance programs, including the top secret PRISM surveillance program.

Operations
Military units that currently occupy the structure include the U.S. Navy's Naval Security Group Activity Hawaii (a combination of the former NSGA Kunia and NSGA Pearl Harbor) and the U.S. Army Military Intelligence Corps 500th Military Intelligence Brigade.

Future
Once complete, the National Security Agency Central Security Service's Hawaii Regional Security Operations Center, which is presently under construction, will replace operations at Kunia Tunnel. The facility, located near Whitmore Village, Oahu, occupies the former site of the large, circular antenna at the Naval Computer and Telecommunications Area Master Station Pacific, or NCTAMS PAC. The construction contract awarded is worth $318 million.
