Q150. On 11 January 2026, DRDO successfully tested which third-generation fire-and-forget missile capable of top attack against moving targets?
[DSSSB MTS, 26 July 2026, Shift 2]
(A) Man Portable Anti-Tank Guided Missile
(B) HELINA
(C) SANT
(D) Nag missile
Answer: (A) Man Portable Anti-Tank Guided Missile
Explanation: The MPATGM is an indigenous portable anti-tank guided missile intended for infantry use. Its imaging infrared seeker guides the weapon after launch, while its top-attack capability aims at the relatively vulnerable upper armour of tanks.
Q149. Which missile did DRDO and the Indian Navy test on 27 February 2025 from Chandipur?
[DSSSB PRT, 19 February 2026, Shift 1]
(A) NASM-SR naval anti-ship missile
(B) BrahMos-II
(C) Pralay
(D) Agni-P
Answer: (A) NASM-SR naval anti-ship missile
Explanation: NASM-SR stands for Naval Anti-Ship Missile–Short Range. The indigenous weapon is intended for maritime attack missions. Trials examined its guidance and flight-control systems, including imaging-infrared target acquisition against naval targets. Its technical work is coordinated with the armed forces and defence manufacturers so that laboratory advances can undergo field evaluation.
Q148. Which organisation collaborated with DRDO in the September 2025 Agni-Prime missile launch?
[RRB Group D, 21 August 2026, Shift 2]
(A) Indian Army Artillery Corps
(B) ISRO
(C) Defence Acquisition Council
(D) Strategic Forces Command
Answer: (D) Strategic Forces Command
Explanation: The Strategic Forces Command is responsible for operational aspects of India’s strategic missile forces. DRDO develops and validates the technology, while joint flight tests help assess operational reliability and readiness of the Agni-Prime weapon system.
Q147. Which institution completed a long-duration ground test of an actively cooled full-scale scramjet combustor in May 2026?
[RRB Group D, 19 August 2026, Shift 3]
(A) Defence Research and Development Organisation
(B) Bharat Electronics Limited
(C) Indian Space Research Organisation
(D) Hindustan Aeronautics Limited
Answer: (A) Defence Research and Development Organisation
Explanation: DRDO conducts propulsion research for indigenous high-speed defence systems. A scramjet burns fuel while incoming air remains supersonic through the combustion chamber. Active cooling helps withstand the enormous thermal loads associated with hypersonic flight.
Q146. Which DRDO missile system completed user-evaluation trials in December 2025?
[RRB Group D, 11 August 2026, Shift 3]
(A) BrahMos
(B) VL-SRSAM
(C) Pinaka-LRGR-120
(D) Akash-NG
Answer: (D) Akash-NG
Explanation: Akash-NG is the New Generation Akash surface-to-air missile system. User trials test whether the missile, radar and command components perform reliably together, an important step before a weapon system can be accepted for operational service.
Q145. Which organisation tested an indigenous high-speed fighter-aircraft escape system in December 2025?
[RRB Group D, 13 August 2026, Shift 3]
(A) Hindustan Aeronautics Limited
(B) Bharat Heavy Electricals Limited
(C) ISRO
(D) DRDO
Answer: (D) DRDO
Explanation: DRDO develops aircraft-survivability technologies alongside weapon systems. High-speed escape tests assess whether ejection or escape components function safely under simulated flight conditions, helping protect aircrew during emergencies. Its technical work is coordinated with the armed forces and defence manufacturers so that laboratory advances can undergo field evaluation.
Q144. Which indigenous long-range surface-to-air missile development initiative is known as Project Kusha?
[RRB Group D, 12 August 2026, Shift 1]
(A) Defence-X
(B) Raksha Shakti Project
(C) Project Suraksha
(D) Project Kusha
Answer: (D) Project Kusha
Explanation: Project Kusha concerns the development of indigenous long-range air-defence interceptors. Such systems combine detection, tracking and guided missiles to engage threats at different distances, strengthening layered protection of critical installations and airspace.
Q143. Dr Tessy Thomas, known for her work on the Agni missile programme, is called what?
[Delhi Police Constable, 5 January 2026, Shift 2]
(A) Missile Woman of India
(B) Rocket Lady
(C) Lady of the Light
(D) Iron Lady of DRDO
Answer: (A) Missile Woman of India
Explanation: Tessy Thomas earned the title Missile Woman of India for her leadership in Indian missile research. She worked on the Agni series and became a prominent woman project leader in the country’s strategic defence-development programme.
Q142. Which strategic missile was tested by India in 2026 to reinforce its deterrence posture?
[DSSSB MTS, 28 April 2026, Shift 2]
(A) Akash
(B) Agni-III
(C) BrahMos
(D) Prithvi-II
Answer: (B) Agni-III
Explanation: Agni-III is a two-stage, solid-fuel, intermediate-range ballistic missile developed for strategic deterrence. Its range and payload place it in a different role from the tactical surface-to-air Akash or the cruise-missile BrahMos. Unlike a cruise missile, a ballistic missile relies chiefly on its momentum and gravity after its initial powered stages.
Q141. What was the advanced stealth-aircraft project showcased by DRDO at Aero India 2025?
[RRB Group D, 6 February 2026, Shift 2]
(A) Advanced Light Weight Torpedo
(B) LCA Tejas Mk2
(C) TEDBF
(D) Advanced Medium Combat Aircraft
Answer: (D) Advanced Medium Combat Aircraft
Explanation: The Advanced Medium Combat Aircraft, or AMCA, is India’s planned stealth multirole fighter project. Its intended features include reduced radar signature, modern sensors and advanced avionics, distinct from the currently operational Tejas aircraft.
