LFDS is an airborne sonar system which can be deployed from rotary wing platforms, for acting as force multiplier for surface vessels. It provides the advantages of lower frequency combined with higher source level for range advantage in littoral ASW. It enables the deployment of sensors to deeper depths for detection of deep dived submarines, thereby substantially enhancing performance. LFDS is an integrated system using indigenous technology capable of simultaneously processing inputs from sonobuoys and operating the dunking sonar for establishing exact range and bearing values with active low frequency transmission.

The LFDS has been primarily developped to be fitted onboard Indian Navy's Dhruv helicopters.
