The Weapons of Mass Destruction Directorate (WMDD) is a division of the National Security Branch of the Federal Bureau of Investigation. WMDD addresses and investigates emerging threats the United States faces from the use of weapons of mass destruction. WMDD specifically consolidates all relevant FBI assets under one comprehensive program capable of detecting, deterring, and dismantling WMD programs. In the wake of the September 11, 2001 attacks, the Division's funding and manpower have significantly increased.
