USS San Francisco in drydock, showing damage to the bow. The round object is the sonar sphere, the subs main sensor, which can hear distant underwater noises. The subs computer system has a library of known sounds, which helps the sub identify what it hears. Next to the nuclear reactor, the sonar system is the most expensive item on the boat.
