Counter-UUV CD Introduction The Maritime Demonstration Program (SMDP) conducted a Capability Demonstration (CD) focused on Countering Unmanned Underwater Vehicles (C-UUV) in Key West, FL in January 2017 Conducted in partnership with multiple stakeholders from operational commands and/or other Government organizations. CD goal is to better understand emerging technologies by integrating them into a demonstration designed to evaluate the ability to fill capability gaps. Provides an opportunity for technology developers to interact with operational commands and/or other Government personnel to determine how their systems may support or enhance operational requirements. Allows technology developers to demonstrate the selected technology in a more realistic maritime environment. Objectives derived from discussions with stakeholders and documents describing previous UUV related events RRTO Strategic Studies Group 3/02/2018Page-3
Counter UUV Background The maturity and proliferation of UUVs throughout the world is presenting an emerging challenge for force protection in harbor environments. 2015 Navy SBIR Unmanned Undersea Vehicle (UUV) Detection and Classification in Harbor Environments (Navy UUV SBIR) Current strategies for detecting and classifying UUVs employ systems that were originally designed to detect combat swimmers and scuba divers. A number of these systems have demonstrated some capability against UUV targets that were presented in a controlled research environment. (Navy UUV SBIR) Various threat studies completed but very limited data available on system performance against UUV targets 3/02/2018Page-4
Counter UUV CD Scope Stakeholders provided input for the FBO Sources Sought C-UUV Parameters (Bound the problem) Limited to Find Fix Track Target (F2T2) Limited to active and or passive acoustic sensors Open to shore-based sensors suspended in the water column to F2T2 threat UUVs approaching or operating in close proximity to pier facilities. Open to sea-based sensors that may include buoys, bottom-sensors, towed sensors, UUV, USV, or combination of capabilities to F2T2 threat UUVs. Scope Conducted in restricted waters at Key West NAS, close to pier within basin and outside basin, with consistent environmental conditions was C2 Platform and launch and recovery vehicle Support assets included smaller UUVs and larger UUV (Remus 100/600) operated by Naval Underwater Systems Shared Resources Center (NUSSRC) Selected/evaluated 7 systems from 4 commercial vendors and 3 government agencies Active and Passive systems 3/02/2018Page-5
Counter UUV CD Objectives Goal: Execute C-UUV CD to demonstrate technologies in a relevant maritime environment against representative threats in scripted and non-scripted mission scenarios Protect assets and waterside facilities from excursions by threat UUV Objective: To evaluate the ability of acoustic (active or passive) systems to Find, Fix, Track, and Target (F2T2) Unmanned Undersea Vehicles (UUV). Evaluate Diver Detection systems Determine state of the art Measures of Effectiveness focused on detection, classification, tracking and targeting Measures of Performance focused on detection range, accuracy, duration, target characteristics, false alarms, etc. 3/02/2018Page-6

Demonstration Plan Each system was evaluated against a larger UUV (REMUS 600 or BF 12) and a smaller UUV (REMUS 100 or BF 9). Systems were evaluated inside the harbor and in deeper waters 8-10 nm SW of Key West. The C-UUV system operators were notified (cued) when each run started and ended, however were not informed of the planned track of the UUVs. The threat UUV approached a simulated high value asset located inside the basin following a prescribed track starting and ending at the harbor entrance (Plan*). * Due to harbor traffic UUV s did not start/end at harbor entrance as planned. UUV ops were limited to western half of harbor area. The target UUV s followed the same track for each run while the speed/depth combination varied 3/02/2018Page-11
Takeaways (Final Report) The harbor environment is (and always will be) extremely challenging ambient noise from harbor traffic, sound refection off harbor walls, bottom clutter, etc. Active vs Passive Sonar considerations Original swimmer/diver detection function Acoustic and environmental conditions that impact UUV operations 3/02/2018Page-12
