Indian Navy gets three naval systems from DRDO  

The Defence Research and Development Organisation (DRDO) has handed over three naval systems to the Indian Navy. These latest systems will significantly enhance the navy’s navigation and communication network.

The systems were handed over to Chief of the Naval Staff Admiral Sunil Lanba by Union Defence Minister Arun Jaitley in New Delhi.

The naval systems given to Indian Navy are

  • USHUS-II submarine sonar
  • Directing gear for hull-mounted sonar array,
  • Inertial navigation system for ship applications.

Defence Minister also released two other products developed by DRDO, namely

  • IP-based secure phone: It incorporates an indigenous encryption algorithm on a “trustworthy hardware platform”. It will provide high level of secrecy to voice and data, for communication of strategic and tactical plans of the Armed Forces.
  • Gallium Nitride Technology: It will substantially help in the development of next generation radars, seekers and communication systems, for application in Light Combat Aircraft (LCA).


Indigenously developed weapon-locating radar SWATHI handed to Army

The Defence Research and Development Organization (DRDO) formally handed over an indigenously developed Weapon Locating Radar (WLR) system dubbed as ‘SWATHI’ to Indian Army.

The DRDO also handed over a Nuclear, Biological and Chemical (NBC) recce vehicle Mk-I and NBC treatment drugs to the Indian Army.


  • Developed by DRDO’s Electronics & Radar Development Establishment (LRDE). It has a range of 50 km which brings all artillery guns presently in service worldwide under its coverage.
  • Performs two roles i.e. Weapon Location Mode for enemy Artillery and Direction of Own artillery Fire (DOOAF) Mode for Artillery.
  • Provides quick, automatic and accurate location of all enemy weapons like mortars, shells and rockets firing within its effective zone of coverage.
  • Simultaneously it can handle multiple projectiles fired from different weapons at different locations. It can also direct artillery response based on the incoming enemy fire.
  • It has been extensively tested along the Line of Control (LoC). Four such systems are currently in operation and another 30 are on order for the Indian Army.
  • The WLR has been a critical requirement of the Indian Army and in the aftermath of the Kargil conflict it was imported from the US in 2002 to fill critical needs.

About NBC recce vehicle Mk-I

  • Developed by DRDO’s Vehicles Research & Development Establishment (VRDE) for carrying out post event recce of Chemical, Biological, Radiological and Nuclear (CBRN) contaminated areas.
  • It is capable of collecting solid and liquid samples of biologically contaminated areas, mark the nuclear and chemical contamination zone and transfer the recce data speedily to support formations.

NBC treatment drugs

  • Developed by DRDO’s INMAS (Institute of Nuclear Medicine and Allied Sciences) which is is actively engaged in research in the field of radio protectors, de-corporating agents and antidotes for CBRN emergencies, combat casualty care and other lifesaving drugs.
  • In the past two decades, INMAS has carried out extensive research and laboratory trials to develop formulations for use as antidotes and de-corporating agents for CBRN emergencies. Out of the several formulas, 15 drugs have been identified for induction.


Supersonic interceptor missile successfully test-fired  

Indigenously developed supersonic Advance Area Defence (AAD) interceptor missile was successfully test-fired from launch complex III of the Integrated Test Range (ITR) at Abdul Kalam Island in Balasore, Odisha.

The supersonic interceptor missile is capable of destroying any incoming enemy ballistic missile at low altitude. The successful test validates the reliability of its two layered Ballistic Missile Defence (BMD) system.

Key Features of missile
  • The AAD interceptor missile has been indigenously developed by DRDO. It is a 7.5-metre-long single stage solid rocket propelled guided missile.
  • It is equipped with a navigation system, a hi-tech computer, inertial navigation system and an electro-mechanical activator.
  • It can destroy the incoming hostile ballistic missile in the endo-atmospheric region (less than 30 km altitude) at a low altitude of less than 30 kms.
  • It has its own mobile launcher, secure data link for interception, independent tracking and homing capabilities and sophisticated radars,

About India’s BMD programme

  • The Research Centre Imarat (RCI) of the DRDO has played pivotal role in the development of all strategic missiles, spearheaded under the India’s double-layered ballistic missile defence (BMD) programme.
  • The BMD consists of two interceptor missiles, Advanced Area Defence (AAD) missile for endo-atmosphere or lower altitudes and Prithvi Defence Vehicle for exo-atmospheric ranges.
  • The DRDO expects deployment of BMD shield by 2022. India will be fourth country in the world after the US, Russia and Israel to successfully built effective anti-ballistic missile system.
  • Earlier in February 2017, DRDO had successfully carried out test of the exo-atmospheric Pirthivi interceptor missile destroying the target outside the earth’s atmosphere at an altitude of over 85 km.
