Phased Implementation:


Demonstration to use BPS-15H Voyage Management System (VMS)
Demonstration Focus: Determine if periscope radar capability is feasible
Avoids investment in production HMI prior to user feedback
Production HMI concepts being developed

FY03 production will utilize simplified Type 18 control/display
May involve use of second watchstander to observe output and contact alerts



FY04 production will utilize Submarine Common Imaging Workstation (SCIC)
No second watchstander
Various Heads-Up Displays will be considered
Engage DEVRON12, COMOPTEVFOR, and TYCOMs
