Q402. Match the following DRDO laboratories in List I with their respective locations in List II:
| Laboratory | Location |
|---|---|
| A. Defence Metallurgical Research Laboratory (DMRL) | i. Jodhpur |
| B. Combat Vehicles Research and Development Establishment (CVRDE) | ii. Hyderabad |
| C. Advanced Numerical Research and Analysis Group (ANURAG) | iii. Chennai |
| D. Defence Laboratory (DL) | iv. Hyderabad |
Explanation
Defence metallurgical research and advanced numerical analysis are conducted in Hyderabad. Meanwhile, the development of combat vehicles is primarily centered in Chennai at the specialized establishment dedicated to armored platforms. Research involving various defense laboratory functions takes place in Jodhpur. These strategic locations allow for focused scientific advancements across diverse geographical hubs supporting Indian military requirements and technological innovation.
Q403. Arrange the following major defense and space milestones in chronological order of their inception or occurrence:
I. Establishment of DRDO
II. First Pokhran Nuclear Test
III. Establishment of ISRO
IV. Launch of IGMDP
Which of the above is the correct chronological sequence?
I. Establishment of DRDO
II. First Pokhran Nuclear Test
III. Establishment of ISRO
IV. Launch of IGMDP
Which of the above is the correct chronological sequence?
Explanation
The strategic timeline of Indian scientific achievements began with the establishment of the defense research organization in 1958. This was followed by the formal creation of the national space agency in 1969. Subsequently, the first peaceful nuclear explosion occurred in 1974. Finally, the integrated guided missile development program was officially launched in 1983 to achieve self-sufficiency in missile technology.
Q404. Which of the following is the official motto of the Defence Research and Development Organisation (DRDO)?
Explanation
The official motto of this premier defense research agency translates to the concept that the source of strength lies in science. This philosophy underscores the commitment to leveraging advanced scientific research and technological innovation to bolster national security. It reflects the organization’s core mission of empowering the Indian armed forces with cutting-edge indigenous systems through rigorous and dedicated scientific exploration.
Q405. Identify the incorrect statement regarding the role and functioning of DRDO.
Explanation
While this organization plays a vital role in national security by advising the government on military logistics and equipment, its primary focus is on defense technology. It collaborates with academia and private industry to develop strategic systems for the armed forces. Designing commercial passenger aircraft is outside its mandate, as such tasks fall under civil aviation and aeronautics development entities.
Q406. What is the primary function of the Technology Development Fund (TDF) scheme executed by DRDO?
Explanation
This specific financial mechanism is designed to foster a culture of innovation by providing crucial support to micro, small, and medium enterprises. By encouraging startups to engage in the design and development of military systems, it aims to reduce dependence on foreign imports. This initiative aligns with the national objective of building a robust and self-reliant indigenous defense industrial ecosystem.
Q407. Consider the following pair: System: NETRA Type of Technology: Airborne Early Warning and Control (AEW&C) System Is this pair correctly matched?
Explanation
This airborne early warning and control system represents a significant milestone in indigenous defense technology. Mounted on an aircraft, it provides crucial surveillance, tracking, and command capabilities to the air force. By detecting incoming threats and managing aerial battles, it acts as a force multiplier. This platform enhances national security through its ability to monitor vast airspaces and coordinate tactical responses.
Q408. Which of the following best defines a Technology Demonstration Vehicle in the context of DRDO’s project classifications?
Explanation
This classification refers to a specialized experimental platform designed to test and prove the feasibility of advanced scientific concepts. Before a weapon system undergoes mass production or induction into the military, these vehicles allow researchers to identify potential flaws and optimize performance. They serve as essential steps in the development cycle, ensuring that final military hardware meets rigorous operational and technical standards.
Q409. DRDO’s spin-off technologies are those that:
Explanation
Scientific advancements originally created for defense applications can often be repurposed for broader public use. These adaptations provide innovative solutions in sectors such as healthcare, disaster management, and telecommunications. By leveraging high-end military research, society gains access to sophisticated tools and materials. This process maximizes the return on national research investments and contributes to the overall technological progress of the country.
Q410. Among the following, which is not a direct responsibility of the Department of Defence Research and Development (DoDRD)?
Explanation
This department is responsible for formulating research programs and providing technical guidance to the defense leadership. It manages numerous laboratories focused on modernizing military equipment through scientific advancement. However, the actual operational and tactical control of soldiers and units during active conflict remains the duty of the military services themselves. Scientific organizations support the defense infrastructure without exercising direct combat command.Answer key for these questions

Key facts from Science and Technology
- The RPSC paper is General Knowledge and General Science, so science questions come with a strong dose of applied and recent topics.
- Everyday science questions test the laws and terms of physics, chemistry and biology through examples.
- Defence and space questions pair a missile, satellite or mission with its year and organisation.
- Policy questions ask for the year, the body and the aim of schemes like STIP, the National Quantum Mission and BioE3.
- Health, environment and agriculture are on a separate page, with their own chapters.
