NNSA's Office of Secure Transportation

The Office of Secure Transportation (OST) is managed by the National Nuclear Security Administration. 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.
