The National Underwater Reconnaissance Office (NURO) is the “hidden younger brother” of the National Reconnaissance Office (NRO). NRO was initiated in 1960 and developed as a common office for United States Air Force and the Central Intelligence Agency (CIA) to manage satellite reconnaissance. The first revelation about NRO came in 1973, but its very existence was not declassified until 1992. According to Jeffrey T. Richelson, “[m]ost often the Under Secretary of the Air Force served as a Director of the NRO”. NURO was initiated in 1969 and developed as a common office or liaison office for the United States Navy and the CIA to manage underwater reconnaissance. NURO used “special project submarines” like USS Seawolf (SSN-575), USS Halibut (SSN-587), and USS Parche (SSN-683) deep inside the waters of the Soviet Union to put out listening devices, tap communication cables, monitor Soviet Navy bases and record sound signatures of Soviet submarines. NURO is a little-known agency; even its name has been secret and its very existence was first revealed in 1998. The United States Secretary of the Navy has served as its director.
Sherry Sontag and Christopher Drew argue that the origin of NURO was the Soviet submarine K-129 that had sunk outside Hawaii in March 1968. When USS Halibut had returned half a year later with 22,000 photos of the Soviet submarine the CIA realized the significance of underwater reconnaissance. NURO was initially formed by CIA Director Richard Helms and dominated by the CIA: “from the day NURO was formed, the CIA [with its Deputy Director for Science and Technology Carl Duckett] took charge. [Captain James] Bradley [from U.S. Naval Intelligence] could spare only a few people for the new office. His entire staff in the undersea part of Office of Naval Intelligence numbered only about a few dozen. The CIA, however, had no such constraints. It moved in with eight permanent staffers and more consultants loyal to the agency”. The Navy prepared to go down with a midget submarine to K-129. However, the CIA wanted the whole submarine. They built the ship ‘’Glomar Explorer’’ (now GSF Explorer) to raise K-129, which became very expensive (up to 500 million dollars). From mid-1970s, the CIA lost its day-to-day control of NURO. Captain James Bradley was able to conduct his own special project operations. Through Bradley it was a direct link to General Alexander Haig and Henry Kissinger. 1972-74, the Secretary of Navy John Warner was the Director of NURO.
