Q129. From which site was India’s first long-range hypersonic missile flight trial conducted?
[DSSSB ASO, 20 August 2025, Shift 1]
(A) Chandipur, Odisha
(B) Nagayalanka, Andhra Pradesh
(C) Junput, West Bengal
(D) Dr A. P. J. Abdul Kalam Island, Odisha
Answer: (D) Dr A. P. J. Abdul Kalam Island, Odisha
Explanation: The maiden trial was conducted from Dr A. P. J. Abdul Kalam Island off Odisha in November 2024. The test was a milestone in indigenous high-speed missile technologies and associated guidance and thermal protection.
Q128. What was the stated power output of DRDO’s laser weapon system developed in early 2025?
[RRB NTPC Graduate CBT I, 10 June 2025, Shift 1]
(A) 30 kilowatts
(B) 10 kilowatts
(C) 20 kilowatts
(D) 40 kilowatts
Answer: (A) 30 kilowatts
Explanation: The archive identifies a 30-kilowatt high-energy laser. Directed-energy systems aim to damage or disable targets using concentrated energy, with potential advantages in engagement speed and cost per shot against certain aerial threats.
Q127. Which DRDO-developed air-defence management system was credited with a role in Operation Sindoor?
[RRB NTPC Undergraduate CBT I, 7 August 2025, Shift 2]
(A) Akashteer
(B) Barak-8
(C) Akash
(D) QRSAM
Answer: (A) Akashteer
Explanation: Akashteer is an automated air-defence command-and-control system, not simply a missile. It links information from sensors and weapon units, supporting coordination and faster decisions when countering hostile aerial activity. Surface-to-air interception also depends on radar detection, tracking information and coordination between the missile and its ground control system.
Q126. DRDO conducted a combat firing of an indigenous multi-influence ground mine in collaboration with which service in May 2025?
[RRB Group D, 16 December 2025, Shift 2]
(A) Border Security Force
(B) Indian Air Force
(C) Indian Army
(D) Indian Navy
Answer: (D) Indian Navy
Explanation: The question identifies the Indian Navy as DRDO’s collaborator. A multi-influence naval mine uses target-related physical signatures to detect suitable conditions for activation, making sensor performance an important part of testing. Its technical work is coordinated with the armed forces and defence manufacturers so that laboratory advances can undergo field evaluation.
Q125. Where was the BrahMos Aerospace Integration and Testing Facility inaugurated in May 2025?
[Punjab Police Constable, 4 June 2025, Shift 1]
(A) Hyderabad
(B) Lucknow
(C) Chennai
(D) Mumbai
Answer: (B) Lucknow
Explanation: The facility opened in Lucknow, Uttar Pradesh, to support missile integration and testing. It forms part of efforts to expand defence manufacturing infrastructure and strengthen the supply chain for the BrahMos programme.
Q124. On which date did DRDO and the Navy test the VLSRSAM from Chandipur in 2025?
[RRB Group D, 8 December 2025, Shift 3]
(A) 26 March 2025
(B) 2 January 2025
(C) 16 July 2025
(D) 20 May 2025
Answer: (A) 26 March 2025
Explanation: The relevant test took place on 26 March 2025. VLSRSAM is a vertically launched short-range surface-to-air missile developed for naval air defence, intended to intercept aerial threats near protected ships. Its technical work is coordinated with the armed forces and defence manufacturers so that laboratory advances can undergo field evaluation.
Q123. Where did DRDO conduct the maiden IADWS flight trials on 23 August 2025?
[RRB Group D, 19 December 2025, Shift 2]
(A) Odisha
(B) Tamil Nadu
(C) Andhra Pradesh
(D) West Bengal
Answer: (A) Odisha
Explanation: The Integrated Air Defence Weapon System trials were conducted off the Odisha coast. Integrated air defence combines different interceptors, sensors and control systems to protect against varied airborne threats. Its technical work is coordinated with the armed forces and defence manufacturers so that laboratory advances can undergo field evaluation.
Q122. Which pair of missile systems was tested within 24 hours in July 2025?
[RRB Group D, 21 December 2025, Shift 1]
(A) Agni-V and BrahMos
(B) Agni-II, Astra and Shaurya
(C) Prithvi-II and Agni-I
(D) iDEX Innovation
Answer: (C) Prithvi-II and Agni-I
Explanation: Prithvi-II and Agni-I are Indian ballistic missile systems associated with strategic strike capability. Sequential user trials help confirm functioning, crew preparedness and operational reliability under defined testing conditions. Unlike a cruise missile, a ballistic missile relies chiefly on its momentum and gravity after its initial powered stages.
Q121. Which upgraded Akash system destroyed two high-speed aerial targets during a July 2025 Ladakh test?
[RRB Group D, 28 November 2025, Shift 1]
(A) BrahMos
(B) Akash Advanced
(C) Akash Prime
(D) Pinaka
Answer: (C) Akash Prime
Explanation: Akash Prime is an upgraded variant of the Indian Akash surface-to-air missile. Improvements are intended to strengthen target interception, including in challenging environments such as high-altitude regions. Surface-to-air interception also depends on radar detection, tracking information and coordination between the missile and its ground control system.
