Sonars: Deep Submergence Obstical Avoidance Sonar (DSOAS): 27 kHz. 8,000 yd Range. Downward Looking Sonar (DLS): 500 kHz Sonar for Hatch Mating 600 ft Range.
Altitude/Depth Sonar (A/D): 24 kHz Sonar 0-5,000 ft. UQC, 8 kHz, Voice and CW, (ATM 504). Directional Listening Hydrophone: Tuned to 3.5 kHz. Side Looking Sonar (Installed for Alternate Mission), 1ft Resolution 183kHz, Max Range 1200ft Either Side (400ft Total).
