COMPTUEX/JTFEX EA/OEA Final Chapter 4 All MK 48 ADCAP exercise torpedoes are inert; out of a 15 minute run, torpedo emitted 30-secaccumulated pinging; both shallow and deep depths were modeled and used in total energycalculation.Tracking Operations Conducted during CSG COMPTUEX and ESG COMPTUEXTracking operations test search and tracking abilities, so rarely involves attack portion of antisubmarinewarfare. When MK 48 torpedoes are incorporated into this training, all torpedoes areinert; emit 30-sec of accumulated pinging throughout a 15 minute run (30 pings); and weremodeled for both shallow and deep depths.Outside SOAR, Tracking Operations did not include MK 48 torpedoes.Ship - AN/SQS-53 and AN/SQS-5675% of the operations will utilize AN/SQS-53 and 25% of the ship operations will use AN/SQS-56 sonar system.Sonar transmission - 67% of the sonar operated in search mode and remaining 33% operated intrack modeAir - AN/AQS-22Dipping sonar (AN/AQS-22) operated in 5 minute on/5 minute off cycle.Six dips per hourHelicopter is stationary during active sonar transmission but changes locations throughout thecourse of the operation.Sub – AN/BQQ-5Submarine does not ping on SOAR Outside of SOAR, submarine emits 15 pings in both shallow an deep water over the duration ofthe operationSubmarine Operations Conducted during CSG COMPTUEX, ESG COMPTUEX, CSG JTFEX, ESG JTFEX30 pings per MK 48 ADCAP exercise torpedo firing (SOAR only)Both shallow and deep water runs were modeledSubmarine emits 5 pings per three hour period (outside SOAR)Modeling Assumptions - Underwater Detonations Operations DescriptionUnderwater Detonations, Mining Operations, and Ship Mine Countermeasures Ordnance net explosive weight: 1-20 lbs Explosive depth: 40 ft (mid source) and 150 ft (deep source) Average sediment (silt) depth – 935 m deep March and September sound velocity profiles modeled4-41 February 2007
