Each mother ship and raider requires high- end GPS, radar and sonar. The best radars available for small ships run about $4,000.

Submarines on a deterrent mission, for instance, tend to congregate in places where they are unlikely to be found by other submarines and spy planes.

Piezoelectricity was used in early sonar devices in World War I and can be found in electric cigarette lighters and some gas grills...
