Storage where you need it

DOE/Sandia National Laboratories

Permanent bunkers and high-security facilities are standard tools for protecting the nation’s most sensitive assets. But in many environments, these options are not available where secure storage is needed most. To meet that challenge, a team at Sandia National Laboratories has developed a mobile, high-security vault that can be rapidly deployed to safeguard critical materials in remote or temporary locations.
