Table 2

Physical subsystems targeted in this study.

Physical subsystems	System group	Subsystem role
Ship steering system	Propulsion system	It controls positional and postural information.
GPS	Navigation sensor system	It detects and calculates positional and postural data of own ship on the water.
INS	Navigation sensor system	It detects and calculates positional and postural data of own ship underwater.
Sonar system	Underwater sensor system	It detects and identifies underwater and surface ship threats.
Plotting board	Surveillance system	It checks overall situations with battlefield condition.
Periscope	Surface sensor system	It checks sea-level situations.
