DRDO, BEL and the Indian Navy have developed and productionized a range of Sonars and related systems for the Indian Navy's frontline combat ships.
These include the:
- APSOH (Advanced Panoramic SOnar Hull mounted),
- HUMVAD (Hull Mounted Variable Depth sonar),
- HUMSA (Follow on to the APSOH series; the acronym HUMSA stands for Hull Mounted Sonar Array),
- Nagan (Towed Array Sonar),
- Panchendriya (Submarine sonar and fire control system).
Other sonars such as the airborne sonar Mihir, are in trials, whilst work is proceeding apace on a new generation of sonars. Sonars may be considered one of DRDO's most successful achievements as the Indian Navy's most powerful ships rely on DRDO made sonars. The standard fit for a frontline Naval ship would include the HUMSA-NG hull mounted sonar, and the Nagan towed array sonar. The Mihir, is a dunking sonar meant for use by the Naval ALH, working in conjunction with its Tadpole sonobuoy. The Panchendriya is in production for the Kilo class submarine upgrades.
DRDO is currently engaged in developing multiple torpedo designs. These include a lightweight torpedo that has been accepted by the Navy and cleared for production ). Other projects include the heavy weight wire-guided torpedo called the Varunastra and the Thakshak thermal torpedo suitable for use against both ships and submarines. The electrically powered Varunastra is now stated to be also in production. The DRDO also developed and productionised a microprocessor controlled triple tube torpedo launcher for the Indian Navy as well as a towed torpedo decoy.
Shyena is an advanced experimental torpedo developed by the Naval Scientific and Technological Laboratory, India's Defence Research and Development Organisation (DRDO) wing. Development was started in 1990.
These have included indigenisation of various components (for instance, adsorbent material for submarines, radar components, naval ship signature reduction efforts and materials technology). DRDO has played a significant role in the development of warship grade steel in India and its productionisation. DRDO has also assisted private industry in developing EW trainers, ship simulators for training and health monitoring systems for onboard equipment. Other equipment for the Navy includes underwater telephone sets, and VLF communication equipment, for the Navy's submarines. DRDO's IRDE has also developed optronic fire control systems for the Navy's and the Coast Guard's ships.
Information command and control systems
DRDO's labs have been part of projects to develop sophisticated command and control systems for the Navy, such as the EMCCA (Equipment Modular for Command and Control Application) which ties together various sensors and data systems. The EMCCA system gives commanders on the ship a consolidated tactical picture and adds to the ship’s maritime combat power.
DRDO labs are also engaged in supporting the Navy's ambitious naval enterprise wide networking system, a program to link all naval assets together via datalinks, for sharing tactical information.
Mines and targets
Three kinds of mines, processor based mine, moored mine and processor based exercise mine are in production for the Navy . Targets developed for the Navy include a static target called the Versatile Acoustic target and a mobile target called the programmable deep mobile target (PDMT).
- A Submarine Escape set, used by crew to escape from abandoned submarines. The set consists of breathing apparatus and Hydro-suit.
- New generation Sonars and EW equipment.
- Heavyweight torpedoes, underwater remotely operated vehicles, improved signature reduction technology for naval applications.
