The Ministry of Defence indicated that in consonance with Government of India’s ‘Make in India’ Policy; Indian Navy on 15th November 2017, has concluded a contract with Tata Power Strategic Engineering Division for supply of Portable Diver Detection Sonar (PDDS) under the ‘Buy and Make (Indian)’ category.

This is the second contract to be signed by the Indian Navy under the ‘Buy and Make (Indian)’ category to boost Government of India’s Defence indigenisation effort.

The maiden contract under this category was also signed earlier by the Indian Navy for supply of Surface Surveillance Radar for IN warships.

Portable Diver Detection Sonar would be manufactured by Tata Power SED in India at their facility at Bengaluru with Transfer of Technology from DSIT Israel.

In a completely indigenous move, a Licensing Agreement for Transfer of Technology (LAToT) of Portable Diver Detection Sonar (PDDS) was signed between Naval Physical and Oceanographic Laboratory (NPOL) and Bharat Electronics Limited (BEL), Bangalore on 15 March 2019. Shri TD Nandakumar, AGM (Naval Systems-1), BEL handed over the first- stage ToT fee to Shri S Kedarnath Shenoy, OS and Director NPOL, at a function organised at NPOL.

Designed and developed by NPOL, PDDS is a portable sonar system capable of detecting potential underwater threats like, divers and diver delivery vehicles in shallow waters. The system alerts the operator with the type of threat so that effective countermeasures can be initiated in time.

The system can be deployed either outboard from a ship or at any location in a harbour. As an auto- alert system, PDDS performs detection, tracking and classification of divers or

diver-like targets automatically and alerts the operator accordingly.

Induction of weapons and sensors under ‘Buy and Make (Indian)’ category, is one the numerous measures being taken by the Indian Navy to boost indigenisation for ensuring a self reliant Navy, in line with the Government of India’s ‘Make in India’ initiative.

Induction of Portable Diver Detection Sonar would further enhance Indian Navy’s Underwater Surveillance Capability in the field of Low Intensity Maritime Operations. Procurement of these sonars for utilisation onboard ships is being undertaken by the Indian Navy to augment countermeasures against asymmetric threats.
