Abstract : The Ocean Engineering Division at the Naval Command, Control and Ocean Surveillance Center RDT&E Division (NRaD) has developed and fielded two successive untethered, supervisory controlled UUV systems: a prototype, and an improved model. These robotic vehicle systems were part of the Advanced Unmanned Search System (AUSS) program that had its genesis in the early 197Os. At that time the idea of performing useful work with untethered robots in the deep ocean was met with some skepticism. Because of this program and the verity of these two vehicles, especially the improved one, we now know that supervisory controlled systems can be employed effectively. A systems engineering approach was applied to the design and construction of the prototype. Nevertheless, it was only after the prototype was fielded, many lessons were leanned, and the prototype experienced major evolutionary changes that system feasibility was fully demonstrated. By that point the prototype had become outdated. As a consequence of the prototype experience, the improved model was developed with confidence. The second system was a complete redesign, using state-of-the-art subsystems and technologies. The resulting product was both capable and reliable, yet flexible, creating a plethora of system evolutionary possibilities. Sea tests, improved tactics, and systems engineering became synergistic and interactive. Increases in vehicle autonomy enhanced the human operator's capability to supervise by decreasing piloting and navigating burdens. The resulting system significantly exceeded expectations, and was delivered to the Fleet. AUSS involved pioneering research in underwater search and in UUV systems. Important knowledge was also gained in systems analysis, system engineering, and program evolution. invaluable experience was gained from 114 successful untethered dives.
