This Article will give you a detailed insight about the educational qualification and the eligibility for becoming a Scientist at DRDO, the exam required to pass for joining DRDO as a Scientist, the Advantages of being a DRDO scientist, etc. 

History & Achievements of DRDO

DRDO has proved to be the most promising organisation of government of India. DRDO Comes under the Ministry of Defence, established in 1958 in order to strengthen India’s own Defence Technologies. Its headquarters are situated in Delhi.

DRDO has made India self-sufficient or rather placed India in the list of top contenders for the next global superpower. The missile program of India IGMDP is a project of DRDO which has developed a varied range of Missiles through the last few decades. Short Range Ballistic missiles like Prithvi series and the Long range type Ballistic missiles series of Agni are the products of IGMDP. IGMDP has also developed cruise missiles like BRAHMOS which is a joint-project of Russia and India. DRDO has also developed Air-to-air, Air-to-surface, surface-to-air, types of missiles.

The Light Combat Aircraft Tejas, a range of Unmanned Air Vehicles (UAVs) , the notable one being the RUSTOM military drone, and electronic warfare systems like AEW&CS (early warning control systems) are some of the achievements of the Aerospace department of DRDO. Nuclear submarines, a range of Naval ships, are some of the achievements of the Marine department of DRDO.

Areas of Research at DRDO

There is a network of around 52 laboratories of DRDO across the country which are dedicated to the research in various fields like Aeronautics, Armaments, Electronics, Combat Engineering, Life sciences, materials, Missiles, Naval systems, etc. One who desires to be a Scientist in DRDO can choose his/her career in the areas of research in accordance with his/her field of study or specialization. 


DRDO develops military Aircrafts like Fighter jets, Unmanned Air Vehicles (UAV or Drone), Helicopters and Electronic Warfare systems like AEW & CS. The notable products of DRDO are LCA tejas which has proved to be quite reliable and is also under prototype stage for Naval variant. The helicopter HAL Dhruv and HAL LCH have also been proved to be of great reliability. DRDO also works on upgrading of the present aircrafts and their armaments. DRDO has recently launched the 5 generation aircraft program of AMCA (advanced medium combat aircraft).

Arms, Ammunition, Artillery

DRDO co-operates with the Ordnance Factories Board for its products. The current main rifle of the Indian Armed Forces, the INSAS along with some other weapons and explosives have been developed by DRDO in the past. It also Develops Tanks and Artillery weapons. 

Electronics and Computer Sciences

The RADAR technology has been developed indigenously by DRDO for the Defence Forces. RADARs are an integral part of defence systems which give early warning signals to the stations. DRDO has also been working on laser guided bombs and missiles. Artificial Intelligence is the emerging field of research and development.

Naval research and Development

The Naval Department works on development of Warships, Submarines, Frigates, & Destroyers. This department is also responsible for the development of Torpedos which are underwater missiles and are referred as Varunastra Sanskrit. 

Missile Systems

India is a leading country in terms of acquisition of Nuclear capable long range Ballistic missiles and is one of very few with Intercontinental Ballistic missiles. The BRAHMOS missile is the fastest supersonic cruise missile in the world with a maximum speed of mach 3. DRDO undertakes missile development in the Aerospace department. 

Actual job of a Scientist at DRDO

A scientist works on research in the field of his specialization.

Every department of DRDO like Missile, Aerospace work in coordination between the different sub departments. For example the Aerospace department comprises sub departments like Design, Thermodynamics, Propulsion, Avionics, Electronics, Mechanics, etc.

Basically the work of a Scientist at DRDO is to research in their area and find ways to make the project more and more efficient and precise.

Education required for becoming a Scientist at DRDO

The candidate is required to at least have a Bachelor’s Degree in Science in the stream of interest with a minimum of 60% aggregate. The candidates with Master’s degree should have passed with a first class. The Scientist C type of posts are allotted to Bachelors in Science. The Scientist B type is allotted to Candidates with BTech (bachelor in technology) or BE (bachelor in engineering) either of the degrees should have been passed with first class.


The candidates with educational qualifications given above should be in the authorized age limit. The candidate must be a citizen of India. The upper age limit is set to be 28 years old. One who is older than 28 will not be eligible to apply. Though there is a relaxation in age limit is given to candidates in SC/ST and OBC categories 5 years and 3 years respectively.
