New Delhi: The four naval systems, ABHAY – Compact Hull Mounted SONAR for Shallow Water Crafts, HUMSA UG – Upgrade for the HUMSA SONAR System, NACS – Near-field Acoustic Characterisation System, and AIDSS – Advanced Indigenous Distress SONAR System for submarines were handed over by the Defence Minister Shri Manohar Parrikar to the Chief of Naval Staff Admiral Sunil Lanba at a special ceremony here today.

The systems have been designed and developed by NPOL, a Kochi based premier laboratory of DRDO which has outstanding contributions and achievements in the design of SONAR systems for the Indian Navy to its credit. ABHAY is an advanced Active-cum-Passive integrated SONAR system designed and developed for the smaller platforms such as shallow water crafts and coastal surveillance/patrol vessels. HUMSA-UG has been designed for upgrading the existing HUMSA SONAR system of the Indian Naval platforms. NACS determines the in-situ performance of the SONAR systems which are used to find the frequency-dependent 3-D transmission and reception characteristics of the SONAR. It is also used to measure the magnitude and phase characteristics of the SONAR transmission and reception electronics and the transducers. AIDSS, a distress SONAR is an Emergency Sound Signalling Device which is used to indicate that a submarine is in distress and enable quick rescue and salvage.

The prototype of this compact SONAR ABHAY installed onboard a nominated Naval platform has successfully completed all user evaluation trials to demonstrate the features as per the Naval Staff Qualification Requirements. Indian Navy has proposed to induct this SONAR on three of the ABHAY class ships. Intensifying the command over the high seas is the HUMSA-UG that is designed for upgrading the existing HUMSA SONAR system of the Indian Naval platforms. The hardware architecture is based on the state-of-the-art open architecture processor technologies that will enable smooth upgrade of the system capabilities. This system is proposed to be installed on seven ships of three different classes of ships.

NACS determines the in-situ performance of the SONAR systems which are used to find the frequency-dependent 3-D transmission and reception characteristics of the SONAR. It is also used to measure the magnitude and phase characteristics of the SONAR transmission and reception electronics and the transducers. The NACS has been integrated with the HUMSA-NG SONAR array and proved onboard Naval platforms and this will be fitted on all frontline ships.

Speaking on the occasion, Shri Parrikar complimented the DRDO and the Navy for their successful joint venture in developing several naval systems, which will provide a fillip to the quest for self-reliance in this critical area of technology. “I expect much more synergy between the Armed Forces and DRDO in the days to come”, he said. He expressed his appreciation to DRDO for its achievements in the last two years particularly in the induction of LCA Tejas, Varunastra Torpedo, Pinaka multi-barrel rocket launcher, Rustom – II UAV and several missile programmes.

Chief of the Naval Staff Admiral Sunil Lanba and Secretary Department of Defence (R&D) & Chairman, DRDO Dr. S Christopher also addressed the function. The function was attended by Scientific Advisor to RM Dr. G Satheesh Reddy and Director, NPOL Shri S Kedarnath Shenoy.
