    Communications The vehicle uses encrypted Inmarsat IV, Iridium, Wi-Fi, and/or freewave enabled communications for operational command, control, system status, and mission re-planning during nearsurface operations, and acoustic communications for command, control, and status messages during submerged operations.
    Buoyancy Control and Trim active buoyancy control system with
  • Autonomous buoyancy control capability
  • Forward and aft trim control
  • Seafloor mooring capability
    • Obstacle Avoidance The vehicle features an active obstacle avoidance capability. The capability is enabled by a Forward-Looking Sonar (FLS) and proven autonomous obstacle avoidance algorithms.
    Terrain Following The vehicle’s FLS system along with a DVL enable terrain following mission capability operations near the seafloor.
