There are a number of unmanned surface vehicles (USV) out there, but the Guardian aims to be the world's first that's capable of being completely submerged for enhanced capabilities. Designed by Juliet Marine Systems, the Guardian is intended to be a low-cost vessel that could be deployed by a wide array of navies around the world for aquatic missions. Being that so much of the world is covered in water, the need for innovative vessels that can be utilized for an array of different aquatic missions is apparent.

The Guardian unmanned surface vehicle measures between 30 and 45-feet in length and features a diesel powertrain that's mixed with a hybrid electric drive. While no Guardians have been created yet, Juliet Marine Systems says construction would take between 18 and 24 months.
