ANT Littoral Glider


 

In 2003 ANT began research and development on its littoral glider system for the Office of Naval Research. Since that time, ANT has delivered 18 gliders to the US Navy and has enhanced the capabilities of the gliders by improving sensor sensitivity and adding mine detection, acoustic temperature profiling, object avoidance and swimmer detection to the already long list of glider capabilities.

ANT has also developed methods for long range detection of surface ships, a ruggedized underwater gliders, Autonomous behaviors for self preservation and mission optimization.

The attributes of the underwater gliders are high endurance, small acoustic cross-section and ability to sample vertically and horizontally. 

The ANT Littoral Glider is built to meet requirements of the Navy’s Unmanned Undersea Vehicle Master Plan.  It features an ability to integrate with the following mission areas: Homeland Defense and Oceanography.
