Officials said that New York residents should not be alarmed at the time, as the exercise would “not pose any risk” due to “training-related activity, including the presence of military personnel and aircraft, and people in protective equipment.”"}},{"type":"header","data":{"text":"Prominent Hunt","level":2}},{"type":"paragraph","data":{"text":"The recent iteration of Prominent Hunt was a large-scale nuclear forensics exercise designed to test the U.S.'s ability to collect and analyze evidence after a nuclear detonation. The operation, led by the FBI and the DoD, primarily focused on developing the U.S.’s ability to rapidly identify the source of a nuclear attack and provide crucial intelligence for national decision-making."}},{"type":"paragraph","data":{"text":"Prominent Hunt is part of an ongoing interagency effort to refine nuclear forensic techniques, with similar training exercises carried out by the FBI and DoD in partnership with other federal agencies in the past. Other participants in January’s round of exercises saw participation from the Department of Energy’s National Nuclear Security Administration (NNSA), the Army’s 20th CBRNE Command, and the Air Force Technical Application Center."}},{"type":"paragraph","data":{"text":"All these agencies contribute to the National Technical Nuclear Forensics Ground Collection Task Force, an interagency group primarily responsible for collecting debris samples from any potential nuclear detonation site. Samples retrieved by participating agencies are transported to DoD labs for analysis, which is a crucial step in determining the origins of any potential nuclear attack."}},{"type":"header","data":{"text":"Determining the Source of a Nuclear Detonation","level":2}},{"type":"paragraph","data":{"text":"Should such a nuclear incident ever occur, forensic analysis will play a critical role in identifying the origin of any such weaponry used."}},{"type":"paragraph","data":{"text":"For instance, unique radiological “fingerprints” left behind from the use of elements like uranium or plutonium can reveal details like the country that produced the material, which grants intelligence officials key insights into questions like whether a state actor, a terrorist group, or some other entity carried out the attack."}},{"type":"paragraph","data":{"text":"Beyond simply identifying the possible perpetrators in the aftermath of a nuclear attack, the DoD said on Wednesday that U.S. agencies publicly demonstrating such forensic capabilities serves as a deterrent to any would-be adversaries planning such attacks."}},{"type":"paragraph","data":{"text":"“National technical nuclear forensics is absolutely a part of nuclear deterrence by messaging to our adversaries that the United States government has the capability, should there be a nuclear detonation,\" said Brian Kohler, director of Nuclear Forensics, Energy, and Survivability at the DOD’s Office of Nuclear Matters, in a statement this week, emphasizing that adversaries must recognize that no nuclear attack will go untraceable."}},{"type":"paragraph","data":{"text":"“These technical skills and tools deny potential perpetrators—including state sponsors of terrorism—anonymity and ensure they will be held fully accountable,\" added Wendin Smith, the NNSA’s associate administrator and deputy undersecretary for counterterrorism and counterproliferation."}},{"type":"header","data":{"text":"Preparing for “Alternative Threats”","level":2}},{"type":"paragraph","data":{"text":"Although nuclear attacks are often associated with missile strikes or explosives used by hostile nations, Prominent Hunt’s main focus involved “alternative” threats that include those posed by terrorist organizations or rogue states, which are more likely to rely on using improvised nuclear devices."}},{"type":"paragraph","data":{"text":"Improvised devices are more likely to be used by such groups since their components can more easily be smuggled into a major population area rather than requiring a launch mechanism. In addition to making the devices less easily detectable before their use, the DoD emphasized on Wednesday that their origins are also less easily traced to any specific nation."}},{"type":"paragraph","data":{"text":"Given the challenges such devices present to U.S. agencies, forensic evidence becomes crucial in helping determine where any such weapon may have come from and how perpetrators got it there. At the heart of this effort is the requirement for collecting on-the-ground data from the detonation site, without which intelligence agencies would face the difficult task of attempting to trace the origins of nuclear devices back to their originators."}},{"type":"paragraph","data":{"text":"Exercises undertaken during Prominent Hunt included training forensic teams to work rapidly to collect radioactive debris from an affected area using models that help predict where debris is likely to fall. This incorporates weather data, as well as explosion yield based on the device's size and surrounding area and the estimated altitude of the explosion."}},{"type":"paragraph","data":{"text":"These models, developed by teams at the Air Force Technical Applications Center, help forensic scientists pinpoint the best collection sites, directing teams from the 20th CBRNE Command to retrieve diverse samples for laboratory analysis. Additional evidence may be gathered in the form of airborne debris. At the same time, satellite surveillance capabilities can also be leveraged to help track where materials may be found in the aftermath of a nuclear attack."}},{"type":"header","data":{"text":"Validating Readiness Through Repeated Exercises","level":2}},{"type":"paragraph","data":{"text":"The DoD is expected to publish an after-action review of January’s training operation in the weeks ahead.
