37 NAVAL OCEANOGRAPHIC OFFICE SYSTEMS ENGINEERING DIVISION N612 MAINTENANCE CONCLUSIONS AND RECOMMENDATIONS SONAR PERFORMANCE IS CONSIDERABLY DEGRADED DUE TO UNDERHULL CONDITIONS. ANY INSTALLATION SHOULD CONSIDER AND INSTITUTE UNDERHULL MAINTENANCE PROGRAMS TO PERIODICALLY GROOM SHIPS TO OPTIMIZE SONAR PERFORMANCE

38 NAVAL OCEANOGRAPHIC OFFICE SYSTEMS ENGINEERING DIVISION N612 FUTURE PLANS “SONAR REPLACEMENTS” EM121A STARTING FY06 SUB-BOTTOM PROFILER FY06 EM1002 FY08

39 NAVAL OCEANOGRAPHIC OFFICE SYSTEMS ENGINEERING DIVISION N612 EM121A REPLACEMENT REQUIREMENTS 1 X 1 DEGREE FULL OCEAN DEPTH MINIMUM OF 190 BEAMS 150 DEGREE SWATH COVERAGE 0.1 % ACCURACY OUTPUT DEPTH, IMAGERY, RAW HYDROPONE ROLL, PITCH, HEAVE, YAW COMPENSATED INSTALLATION OPTIONS “V” RECESSED IN HULL FLAT ARRAY ON WING INTEGRATED SUBBOTTOM PROFILER

40 NAVAL OCEANOGRAPHIC OFFICE SYSTEMS ENGINEERING DIVISION N612 The following slides show a typical installation of a EM120 Deep Water Multibeam Includes a narrow beam subbottom profiler that uses the same receive array as the multibeam. Underhull appendage is slightly more than that on a T-AGS 60 ship. This gondola arrangement also includes all of the other transducers mounted on the existing T-AGS 60 This is one of several installation methods that N61 is considering for the EM121A replacement.
