DRDO, ATAGS - Current Affairs Questions and Answers

1)   DRDO has developed an unmanned remote operating tank called _______ in July 2017.

a. Muntra
b. Mundra
c. Mutra
d. Mudra
Answer  Explanation 

ANSWER: Muntra

Government agency Defence Research and Development Organisation (DRDO) has developed India's first unmanned tank that can remotely operate and has named it ‘Muntra’.

The agency has developed the tank in three different variants to tackle any kind of situation- for surveillance, another for mine detection and a third variant for reconnaissance in areas with nuclear and bio threats.

The tank which is a first of its kind in the country has been developed and tested by Combat Vehicles Research and Development Establishment (CVRDE) in Avadi for the army.

The paramilitary has expressed its interest in using them in the areas that have been affected by the Naxals.

Recently two vehicles that have been designed like an armoured tank were recently displayed at the Science for Soldiers exhibition that was organised by DRDO as a tribute to former President APJ Abdul Kalam, who was also known as the Missile Man of India.

During the testing of the vehicle, it was found that its surveillance radar that includes an integrated camera can be used to spy on targets that are 15 km away.

More about the variants of the unmanned tank ‘Muntra’-

Muntra S – This variant has been developed to carry out unmanned surveillance missions.

Muntra M – This variant has been developed for detecting mines.

Muntra N – This variant will be deployed in areas where nuclear radiation or the risk of bio weapons is high.

The tanks have been tested and validated at Mahajan field firing range in Rajasthan.

The Muntra tanks have surveillance radar, an integrated camera along with laser range finder, which can be used to spy on ground target about 15 kilometres away.

Besides heavy weights, the DRDO also showcased a few inventions like a handheld wall penetration radar which if placed on a wall will project on a screen the presence of people inside a building.

DRDO is now working on installing AWAC (Airborne Early Warning and Control System) on an A330 aircraft.

The system is now perfected for use on a smaller Embraer plane.

2)   Defence and Finance Ministry inaugurated the DRDO ATR in which location?

a. Chitradurga Karnataka
b. Medak AP
c. Panaji, Goa
d. None of the above
Answer  Explanation 

ANSWER: Chitradurga Karnataka

Aeronautical Test Range (ATR) is the first of its kind range that has been set up by the Aeronautical Development Establishment (ADE), one of the premier laboratories of the DRDO.

ADE works on a range of UAVs (unmanned air vehicles). The facility will be an integrated test centre for a cluster of DRDO’s aeronautical laboratories.

The following labs will make use of the testing facility: the Centre for Air Borne Systems, the Gas Turbine Research Establishment, the Defence Avionics Research Establishment, the Centre for Military Airworthiness & Certification, all of which are based in Bengaluru, and finally the Aerial Delivery Research & Development Establishment, which is based in Agra.

The facility is meant to conduct flight-tests of indigenous unmanned and manned aircrafts such as naval and trainer versions of the Light Combat Aircraft, the unmanned air vehicles- Rustom-I and Rustom-II (Tapas); the Airborne Early Warning & Control Systems (AEW&C), Air-to-Ground weapons, parachutes and aerostats, etc.

Karnataka, especially Bengaluru, and its tech ecosystem not only leads India, but is a leader on the global horizon.

Technology companies and their facilities located in Bengaluru are helping us create new facilities in other places in the country.

DRDO indicated the ATR, sprawling 4,090 acres, was built at a cost of INR 290 crore.

The ATR campus has 31 buildings and a 2.2km runway that can be expanded to 3km to help larger aircraft land and take off.

It has two hangers to house UAVs, radar centre, fibre-optic network, and a separate residential complex on 200 acres.

3)   DRDO has signed a technology transfer agreement for manufacture of which steel?

a. High nitrogen steel
b. Steel alloy
c. Both of the above
d. None of the above
Answer  Explanation 

ANSWER: Both of the above

The Defence Research and Development Organisation (DRDO) has signed a technology transfer agreement with Jindal Stainless (Hisar) Ltd. (JSHL) for manufacturing high nitrogen steel (HNS).

The steel alloy has significant applications in the defence sector, but currently the country is mostly dependent on imports.

HNS has higher ballistic strength and is not only tough but also has good strength.

It is non-magnetic and corrosion-resistant.

It costs about 40% less than that of rolled homogenous armour steel (RHA).

Its domestic production will further the Indian Army’s quest for lighter armouring material.

HNS: Know More

  • HNS is corrosion resistant and provides exceptional ballistic and blast protection than the existing material.
  • This is at a much reduced thickness along with longevity which increases the fuel and mass efficiency.
  • It exhibits higher energy absorption.
  • Aim is to launch additional variants of HNS with enhanced blast and ballistic protection to cater to niche requirements of the defence sector.
  • HNS passed ballistic tests in different calibers with 8-10 times higher impact and blast protection.
  • It has potential application in all armoured vehicles, including infantry combat vehicle (ICV), light speciality vehicle (LSV), light armoured multi-purpose vehicle (LAMV), futuristic infantry combat vehicle (FICV), main battle tank (MBT), future ready combat vehicle (FRCV), aviation and naval systems.

4)   DRDO has signed an MOU with which IITs to establish a Centre of Propulsion Technology?

a. IIT Bombay
b. IIT Madras
c. Both a and b
d. None of the above
Answer  Explanation 

ANSWER: Both a and b

Defence Research and Development Organisation has signed an MoU with IIT-B and M to establish a bi nodal Centre of Propulsion Technology.

  • MoA was signed to achieve synergy between DRDO and IITs for channeling research efforts and advanced collaborative research in areas of critical defence technologies.
  • CoPT will facilitate and undertake multidisciplinary directed research in the following areas:
  • futuristic aero engines,
  • hypersonic propulsion for long duration flights,
  • solid propellant combustion modelling
  • morphing aircraft technologies.

5)   Tejas is a ___ generation fighter aircraft developed in the country after technology gap of two decades of HF Marut by DRDO.

a. 2nd
b. 3rd
c. 4th
d. 5th
Answer  Explanation 


Tejas is a 4th generation fighter aircraft indigenously developed in a nation after technology gap of two decades of HF Marut by DRDO.
