The '''Advanced Unmanned Search System (AUSS)''' was a submersible employed by the [United States Navy](/source/United_States_Navy) constructed from a [carbon-fiber reinforced plastic](/source/Carbon-fiber_reinforced_polymer) cylinder with [titanium](/source/titanium) semi-spheres at the ends. The vessel measured {{convert|17|ft|m}} in length, and was {{convert|31|in|cm}} wide.

It was able to operate at depths of up to {{convert|20000|ft}}, autonomously and untethered. Commands were send to the craft via sonar modem at a bitrate of 1,200 bits per second (bit/s), and the AUSS sent back data at rate of 4,800 bit/s. The controllers at the surface defined the targets and the search patterns, while the submersible executed the search patterns autonomously, without any realtime inputs.

Its [silver-zinc batteries](/source/Silver_zinc_battery) allowed an endurance of 10 hours, while recharging lasted 20 hours. The AUSS navigated with a [gyrocompass](/source/gyrocompass) and [Doppler](/source/Doppler_effect) [sonar](/source/sonar).
