Integrated maritime portable acoustic scoring simulation impass system live firing brief

Mission Objectives (IMPASS) System

Certify CIC and gun weapons system personnel to deliver NSFS to a landing force under simulated combat conditions

Conduct NSFS certification (FIREX) IAW FXP-5 (B) and the SFEM (COMNAVPACINST/ COMNAVLANTINST 3500.11)

Gather data for BL&P scoring threshold and IMPASS Block III system performance

Familiarize shipboard personnel in the use and operation of IMPASS

Environmental Regulatory Compliance (IMPASS) System

  • Through informal consultation under the Endangered Species Act, the Navy and National Marine Fisheries Service have agreed to the following marine life mitigation measures in order to minimize impacts to protected marine species:

    • Marine mammal/sea turtle lookouts will have completed the US Navy Marine Species Awareness Training

    • Approx 1 hour pre-exercise monitoring of target area conducted with “big eyes” during deployment and transit to firing position

    • The ship will not fire on the target area if any marine mammals or sea turtles are detected within or approaching the buoy field/ target area until the area is cleared


Integrated maritime portable acoustic scoring simulation impass system live firing brief

Environmental Regulatory Compliance (IMPASS) System

  • Passive acoustic sonobuoys (3 DIFARS) will be deployed during the IMPASS buoy deployment (DIFARS dropped at buoy positions 2, 4 and 5) (See LOI for NCEA)

  • If an animal is sighted or detected in, or moving towards the buoy field, contact the IMPASS Team Leader. If Team Leader and CO concur, the exercise will be temporarily halted while the ship conducts visual clearance of the buoy field for 15-20 minutes or until the animal has been visually observed to have cleared the buoy field and is heading away from the Impact Zone

Environmental Regulatory Compliance (IMPASS) System

  • Post-exercise monitoring of the entire impact area during retrieval of the IMPASS buoys will take place with “Big Eyes” and the naked eye following the exercise

  • Any injured sea turtle or marine mammal sighted during the exercise will be reported immediately via UNIT SITREP

  • Naval vessels should avoid approaching any whale or sea turtle head on, and should maneuver to maintain at least 460m (500 yds) from any observed whale or sea turtle

Environmental Regulatory Compliance (IMPASS) System

  • If a marine mammal is detected within 70 yards of the firing platform the FIREX will be suspended until the marine mammal is outside of the 70 yard perimeter

70 Yds

Temporarily suspend FIREX


Pre event planning
Pre-Event Planning (IMPASS) System

  • Establish/Verify FSA for exercise (IAW LOI and FACSFAC OPSKED)

  • Pre-plan buoy drop coordinates (Buoy coordinates provided by IMPASS Team)


Buoy deployment
Buoy Deployment (IMPASS) System

  • No-Go criteria

    • Sea state 3 or greater at time of deployment or forecast to be 3 or greater at time of recovery

    • Reduced visibility

      • Optimum visibility allows

        ship to observe fall of shot

    • Lightning

      • Deployment/recovery will be

        suspended when lightning is

        observed


Event set up
Event Set-up (IMPASS) System

  • Day of exercise:

    • Muster buoy handling team 1 hour prior to sunrise

    • Require helo hangar doors to be open (If applicable)

    • Require topside lighting for moving buoys safely

    • Mount two radio repeaters - one on each bridge wing

    • Set-up IMPASS control station on bridge data modem & 2 laptops (Stbd side preferred)


Assembly deployment
Assembly/Deployment (IMPASS) System

Supervised by IMPASS TEAM with a minimum of 10 support personnel from ship’s company


Xbt sound velocity
XBT – Sound Velocity (IMPASS) System

  • Ship’s sonar tech deploys XBT at buoy position 1

  • Provide sound velocity profile data and graph to IMPASS operator on bridge

    • IMPASS operator will compare XBT data to IMPASS generated sound velocity data

  • IMPASS requires sound velocity data to be manually entered into system for accurate solutions

Buoy Deployment (IMPASS) System

  • Buoy deployment requires 30-45 minutes from first position

    • RHIB at the ready

    • Request SPY be placed in standby while buoys are topside and remain in standby until ship is three miles from buoy field

  • Drop buoys at pre-determined positions

    • Use ship’s NAV to drive ship to drop-off points

    • Buoys lowered from fantail and dropped on command from Bridge (Require communications directly with bridge and countdown to drop point)


Integrated maritime portable acoustic scoring simulation impass system live firing brief

Buoy Deployment (IMPASS) System

  • Drop buoys at pre-determined positions

    • Drop as close as possible to pre-planned coordinates (Not precision anchorage type exercise)

    • Ship should maintain a steady course through the buoy drop point at 4-5 knots for optimum buoy deployment and to provide good opening speed once buoy is deployed

    • Ship SHOULD not back down, twist or turn until buoy is clear

    • IMPASS team member on fantail will indicate when buoy is clear and ship is safe to maneuver

    • Upon completion of buoy field deployment, TEAM IMPASS will provide recommended position for ship to start first firing run

  • IBC procedures are contained in:

    • SW300-BD-ORD-010/(U): Preparation, Analysis and Predicted Accuracy of Naval Gunnery

  • Manually enter computed IBC data at GMCP

Retrieval Procedures (IMPASS) System

  • Break off from FIREX and begin buoy recovery with 2 hours of good visibility/2 hours prior to sunset (Sea State 3)

    • Secure SPY prior to closing within 3 miles of buoy field

    • IMPASS team provides range and bearing to each buoy

    • Recommend 2 RHIBs to expedite buoy recovery

    • 3 personnel required to lift buoy into RHIB and disassemble

    • Maximum 3 buoys per RHIB due to weight of buoys and to prevent damage to buoys

    • Buoys unloaded from RHIB at the rail or after RHIB has been recovered and in the skids
