Q502. Consider the following statements about ATAGS:
Statement I: It achieved a maximum firing range of approximately 48 km during trials.
Statement II: It uses an automated ammunition handling system to fire successive rounds rapidly.
Which of the above statement(s) is/are correct?
Statement I: It achieved a maximum firing range of approximately 48 km during trials.
Statement II: It uses an automated ammunition handling system to fire successive rounds rapidly.
Which of the above statement(s) is/are correct?
Explanation
During rigorous testing, this artillery system proved its ability to hit targets at distances of nearly fifty kilometers. This impressive reach is complemented by an automated system for loading ammunition, which allows the crew to fire multiple rounds in quick succession. These features together provide a high volume of accurate fire, significantly increasing the tactical effectiveness of the gun on the battlefield. It represents a major advancement in the nation’s indigenous long-range artillery capabilities and technology.
Q503. The conceptual integration of an all-electric drive in the ATAGS ensures:
Explanation
The use of electrical systems to move the gun and its components offers several advantages over traditional fluid-based mechanisms. These systems are generally more reliable in extreme weather conditions and require less frequent servicing. By eliminating the need for complex hydraulic pipes and pumps, the overall maintenance burden is reduced. This modern design choice ensures that the artillery piece remains operational for longer periods during intense military deployments and challenging field conditions across various terrains.
Q504. Which of the following is a negative statement regarding the capabilities of ATAGS?
Explanation
While the gun possesses many advanced features like a high rate of fire and a large chamber for powerful charges, it does include an auxiliary power unit. This unit allows the gun to move itself short distances without needing a towing vehicle, which is a significant advantage. Statements claiming that the system lacks this self-propulsion capability for minor adjustments are incorrect. The inclusion of such power units is a standard feature in modern heavy towed artillery.
Q505. The ATAGS project is a prime example of which Indian government defence initiative?
Explanation
This artillery project is a centerpiece of the national drive to achieve independence in defense manufacturing. By designing and building a world-class weapon system within the country, it reduces the need for expensive foreign imports. It showcases the ability of domestic scientists and private companies to collaborate on high-technology military hardware. The success of this gun is a significant step toward the goal of making the nation self-sufficient in its strategic and conventional military requirements.
Q506. What is the tactical effect of equipping the ATAGS with an Advanced Fire Control System and an Auxiliary Power Unit?
Explanation
The integration of an advanced targeting computer and an internal power source allows the gun to be prepared for firing and then moved quickly. This ability is vital for surviving on a modern battlefield, where enemy radar can quickly locate an artillery position after it fires. By firing a few rounds and then rapidly shifting to a new location, the gun avoids counter-fire. These technologies together greatly enhance the survivability and tactical flexibility of the artillery unit.
Q507. Identify the odd one out among the following artillery guns in relation to indigenous development in India:
Explanation
This specific artillery system was originally purchased from a European nation in the late twentieth century. While it has been widely used by the military, it is not an indigenous design. In contrast, the other listed systems are either entirely domestic developments or represent significantly upgraded versions produced locally. The foreign-sourced gun stands out as the exception in a list otherwise focused on the nation’s growing capabilities in the design and production of its own artillery hardware.
Q508. ISRO was established in 1969 to replace which of the following organizations?
Explanation
Before the formal creation of the current space organization, activities were managed by an initial committee formed in the early sixties. This group laid the foundation for atmospheric and space research. In 1969, it was reorganized into the present body to better manage the growing complexity of the country’s space program. This transition marked the beginning of a more structured and ambitious era of satellite development and launch vehicle technology to meet national development goals.
Q509. Who is historically credited as the founding father of the Indian space programme?
Explanation
This eminent scientist is widely recognized for his visionary role in starting the nation’s space journey. He believed that space technology should be used for the direct benefit of society, particularly in areas like communication and education. His efforts led to the creation of the national space agency and the development of early research facilities. His legacy continues to guide the organization’s mission to leverage space science for the socio-economic progress of the country.
Q510. Consider the following statements:
Statement I: The overarching vision of ISRO is to harness space technology for national development.
Statement II: ISRO primarily focuses on manned military space stations.
Which of the above statement(s) is/are correct?
Statement I: The overarching vision of ISRO is to harness space technology for national development.
Statement II: ISRO primarily focuses on manned military space stations.
Which of the above statement(s) is/are correct?
Explanation
The primary goal of the space agency has always been to apply advanced technology to solve national challenges and aid development. This includes areas such as weather forecasting, remote sensing, and telecommunications. However, the organization’s focus is primarily on civil and scientific exploration rather than the development of manned military space stations. While it works on human spaceflight, the mission objectives are scientific and technological in nature, aimed at expanding the nation’s presence in space.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.
