AFTAC is also on the forefront of protecting the homeland as it establishes an array of sensors across the United States as part of the National Technical Nuclear Forensics (NTNF) program. This program is designed to collect forensic analysis after detonations to aid the Federal Bureau of Investigation in attributing attacks on U.S. soil to foreign governments or terrorist entities to swiftly bring those responsible to justice. AFTAC's efforts are making the Department of Defense's vision to protect U.S. personnel and interests from the threat of a domestic nuclear detonation a reality.
