Zirconic
Template:Short description Template:About Template:Use American English Template:Use dmy dates
Zirconic was a National Reconnaissance Office (NRO) codename for a program established under the Presidency of Ronald Reagan to develop reconnaissance satellites equipped with stealth technology. Zirconic operated as a sensitive compartmented information program and included the Misty and Prowler spacecraft, which were designed to reduce radar, visible, infrared, and laser signatures. Access to related classified material required a dedicated "Zirconic clearance," and the program's development effort was internally codenamed Nebula.
Misty deployments began in 1990, when Misty 1 launched aboard the Space Shuttle Atlantis and was deployed "over the side" rather than through a conventional payload bay ejection; amateur observers nevertheless tracked it within months. Misty 2 followed in 1999 on a Titan IV-B rocket, during which observers noted the release of a high-altitude decoy intended to obscure the true payload's orbit. A subsequent classified follow-on, Prowler, remained under strict compartmentalization, and its operational details have never been publicly disclosed.
By the early 2000s, Zirconic had become one of the largest single line items in the U.S. intelligence budget, with Misty's development costs rising from US$5 billion to more than US$9 billion by 2004. The program drew scrutiny from the numerous United States Congress committees. Critics argued that extreme secrecy enabled unchecked spending and limited transparency. Supporters maintained that stealth capability provided unique intelligence advantages in situations where adversaries believed no satellites were overhead.
History
The NRO considered stealth reconnaissance satellites as early as 1963.<ref name="Richelson NRO 2004-12-14" /> A 1983 Department of Defense report noted that Soviet anti-satellite systems were operational and capable of targeting U.S. spacecraft in low Earth orbit, reinforcing the rationale for a stealth imaging platform.<ref name="Richelson NRO 2005-05-01" /> In 1994, Teledyne Industries received a patent for a "satellite signature suppression shield" designed to reduce a spacecraft's laser, radar, visible, and infrared signatures.<ref name="Richelson NRO 2004-12-14" />
The Zirconic compartment was established under the Ronald Reagan within the Byeman Control System (BYEMAN).<ref name="Leonard Space NRO 2005-01-03" /> The development effort was internally codenamed Nebula, and access to the related information was restricted to individuals granted "Zirconic clearance."<ref name="Leonard Space NRO 2005-01-03" />
Jeffrey T. Richelson first disclosed the Zirconic program in his 2002 book, The Wizards of Langley: Inside the CIA's Directorate of Science and Technology.<ref name="Priest WAPO NRO 2004-12-11" /> The program entered wider public awareness in December 2004, when the Washington Post and New York Times reported on it.<ref name="Richelson NRO 2004-12-14" /> In late 2004, the Senate Intelligence Committee voted to terminate Zirconic,<ref name="Richelson NRO 2004-12-14" /> but the program continued due to the support of the House Intelligence Committee and both the House Appropriations Committee and Senate Appropriations Committee.<ref name="Richelson NRO 2004-12-14" />
Senator Jay Rockefeller made repeated efforts to end the program.<ref name="Richelson NRO 2004-12-14" /> After Rockefeller and other Democratic senators hinted at the still-classified program's existence, Senate Republicans questioned whether any congressional rules had been violated.<ref name="Jehl NYT NRO 2005-01-03" /> Opposition from both parties was described as intense and sustained behind closed doors for two years.<ref name="Jehl NYT NRO 2005-01-03" /> Senator Ron Wyden argued that unmanned aerial vehicles could achieve Misty's objectives at substantially lower cost and risk,<ref name="Richelson NRO 2005-05-01" /> while George J. Tenet and Porter J. Goss were cited as staunch supporters.<ref name="Priest WAPO NRO 2004-12-11" />
According to the Washington Post, Lockheed Martin served as a lead contractor on Zirconic.<ref name="Priest WAPO NRO 2004-12-11" /> By 2004, Misty's development costs had risen from US$5 billion to over US$9 billion,<ref name="Priest WAPO NRO 2004-12-11" /> with annual spending estimated in the hundreds of millions of dollars.<ref name="Jehl NYT NRO 2005-01-03" /> The same report stated that Zirconic's stealth satellite line was the largest single line item in an approximately US$40 billion intelligence-related budget.<ref name="Priest WAPO NRO 2004-12-11" /> The planned third and final satellite, Misty, followed earlier launches in 1990 and 1999.<ref name="Priest WAPO NRO 2004-12-11" />
Writing for European Security & Defence, Douglas Richardson noted the involvement of Edward Mills Purcell in Zirconic and earlier Corona programs "to make these vehicles, if not invisible to radar, hard to observe with radar."<ref name="Richardson Sanctuary NRO 2005-05-01" /> Analysts also observed that the Space-Based Infrared System (SBIRS), the Advanced Extremely High Frequency (AEHF) communications network, and the optical and radar components of the Future Imagery Architecture experienced comparable cost growth during the same period.<ref name="Leonard Space NRO 2005-01-03" />
Critics argued that secrecy surrounding programs like Zirconic enabled unchecked spending, as industry lobbyists with the necessary clearances had privileged access while skeptics remained uninformed.<ref name="Leonard Space NRO 2005-01-03" />
Satellite details
A 1971 patent filed by employees of TRW Inc. (later acquired by Northrop Grumman) proposed a satellite design that could mask its radar cross-section, making it appear to remote sensors as a benign spacecraft.<ref name="Richelson NRO 2005-05-01" /><ref name="TRW Barker Slager 6107952" /> The patent described a crossed-skirt antiradar screen structure capable of either suppressing a satellite's radar cross-section or imitating the signature of a benign spacecraft.<ref name="Richelson NRO 2005-05-01" /><ref name="TRW Barker Slager 6107952" />
Two decades later, staff of the Strategic Defense Initiative (SDI)—later reorganized as the Missile Defense Agency (MDA)—filed a similar patent.<ref name="Richelson NRO 2005-05-01" /><ref name="SDI NRO 5345238" /> The 1990 public patent for a satellite signature suppression shield prompted internal concern within the NRO over potential exposure of classified methods.<ref name="Richelson NRO 2005-05-01" /> Because of extreme compartmentalization, Misty's developers did not consult key satellite-tracking experts at agencies such as the Naval Research Laboratory, potentially overlooking alternative assessments.<ref name="Richelson NRO 2005-05-01" /> The Misty program was managed under the CIA's Directorate of Science and Technology (DS&T), specifically its Office of Development and Engineering (OD&E).<ref name="Richelson NRO 2004-12-14" /> Analysts noted that stealth satellites were less versatile than standard reconnaissance assets and useful only in rare circumstances when adversaries believed no satellites were overhead.<ref name="Leonard Space NRO 2005-01-03" />
The Misty satellite was designed to take photographs during daylight hours and in clear weather.<ref name="Jehl NYT NRO 2005-01-03" /> However, it lacked the capability to capture imagery in all-weather conditions.<ref name="Richelson NRO 2005-05-01" /> An early proposal to maintain a satellite in a high parking orbit and deorbit it only when needed was abandoned after it was determined that film would degrade while in storage.<ref name="Richelson NRO 2005-05-01" />
The camouflage space shield described in the SDI patent took the form of an inflatable balloon that could be rapidly deployed and then hardened through exposure to both external and internally generated ultraviolet radiation.<ref name="Leonard Space NRO 2005-01-03" /><ref name="SDI NRO 5345238" />
The Misty satellite launched from the Space Shuttle Atlantis in 1990 was deployed "over the side" rather than through the standard payload bay ejection.<ref name="Leonard Space NRO 2005-01-03" /> Following the 1999 Titan IV-B launch of Misty 2, amateur satellite trackers concluded that the spacecraft released a high-altitude decoy object.<ref name="Richelson NRO 2005-05-01" /> The decoy was intended to obscure the true payload, which operated in a much lower orbit.<ref name="Richelson NRO 2005-05-01" /> Despite Misty 2 being operational, U.S. overhead assets failed to detect North Korean uranium enrichment activities; the discovery was instead made by tracking aluminum tube shipments.<ref name="Richelson NRO 2005-05-01" /> After the 1990 launch, both U.S. and Soviet sources incorrectly reported that Misty had malfunctioned and would soon reenter the atmosphere.<ref name="Richelson NRO 2005-05-01" /> The CIA later confirmed that the satellite remained operational.<ref name="Richelson NRO 2005-05-01" /> In its early use, the KH-11 satellite was mistakenly identified by Soviet analysts as a signals intelligence platform.<ref name="Richelson NRO 2005-05-01" /> As a result, they reduced their concealment efforts during the satellite's overpasses.<ref name="Richelson NRO 2005-05-01" />
A formal threat assessment by the CIA's Office of Scientific and Weapons Research (OSWR) concluded that Soviet tracking systems were unlikely to detect Misty.<ref name="Richelson NRO 2004-12-14" /> Despite its intended stealth, Misty 2 was visually detected by amateur observers within eight months of launch, who tracked it at an altitude of approximately Template:Convert.<ref name="Richelson NRO 2005-05-01" /> Misty remained in orbit as late as May 1995, though its location and further intelligence contributions thereafter remained unknown.<ref name="Richelson NRO 2004-12-14" />
