Office of Secure Transportation

The Office of Secure Transportation (OST) is managed by the National Nuclear Security Administration within the U. S. Department of Energy.

OST is responsible for the safe and secure transport in the contiguous United States of government-owned special nuclear materials. These classified shipments can contain nuclear weapons or components, enriched uranium, or plutonium. The cargo is transported in highly modified secure tractor-trailers and escorted by armed Federal Agents in other vehicles who provide security and national incident command system response in the event of emergencies.

While OST is headquartered in Albuquerque, New Mexico, there are three commands from which OST Federal Agents operate: Albuquerque, New Mexico; Amarillo, Texas; and Oak Ridge, Tennessee. The OST Training Command is located at Fort Chaffee, Arkansas. A key component of OST operations is our law enforcement / emergency management liaison program. OST provides briefings to various federal, tribal, state, and local organizations on which OST depends for support. The purpose of these briefings is to inform organizations of OST's existence so they may gain a better understanding of the program, to learn firsthand about OST's intense emphasis on safety and security and possible support requirements in the event of an incident or emergency. This effort also helps OST improve understanding of each state’s support capability.

Transportation and Emergency Control Center (TECC)

The Office of Secure Transportation TECC is a nationwide communications system operated by NNSA and located in Albuquerque, N.M. This center monitors the status and location and maintains real-time communications 24 hours a day, 365 days a year, with every convoy.

The TECC also maintains an emergency contact directory of federal and state response organizations located throughout the contiguous United States.


NNSA makes every effort to ensure its convoys do not travel during inclement weather. Should the convoys encounter adverse weather, provisions exist for the convoys to seek secure shelter at previously identified facilities.

Law Enforcement / Enforcement Management Liaison Program

NNSA has a liaison program through which it communicates with law enforcement and public safety agencies throughout the country, making them aware of the secure transport mission. Those interested in a briefing or with any questions concerning NNSA’s secure transport operations, contact the Liaison Support Branch at (505) 845-4488 or (800) 424-0167.
