The SSQ-101B is a NATO A‑size sonobuoy engineered for the U.S. Navy and built to deliver commandable passive search capability. It is manufactured to rigorous military standards and provides dependable performance for ships and aircraft conducting underwater surveillance.
When deployed, the SSQ-101B uses a horizontally oriented, pentagon‑shaped pattern of forty hydrophones to detect and beam‑form underwater sound. Each hydrophone’s analog output is digitized, serialized, and beam‑formed within the buoy, then transmitted through a minimum five‑watt FSK‑modulated radio link. Bearing accuracy is strengthened by a high‑precision digital compass. The buoy includes Electronic Function Select for pre‑launch configuration and a UHF Command Function Select downlink.
