Q100. Which country became the first export customer for India’s BrahMos missile?
[NDA I, General Ability, 10 April 2022]
(A) Bhutan
(B) Philippines
(C) Maldives
(D) Nepal
Answer: (B) Philippines
Explanation: The Philippines signed a contract for BrahMos coastal-defence missiles in January 2022. The order became a major defence-export milestone for the Indo-Russian supersonic cruise-missile programme. Cruise missiles remain powered through most of their guided flight, which distinguishes their operating principle from ballistic missiles.
Q99. What is the name of the Akash missile variant tested in September 2021 with an active RF seeker?
[DSSSB Junior Secretariat Assistant, 5 April 2022, Shift 2]
(A) Akash Prime
(B) Akash Pramukh
(C) Akash Miniline
(D) Akash Superway
Answer: (A) Akash Prime
Explanation: Akash Prime is an upgraded version of the Akash air-defence missile. Its active radio-frequency seeker enhances target engagement capability, supplementing the radar, launcher and control elements of the wider weapon system. Surface-to-air interception also depends on radar detection, tracking information and coordination between the missile and its ground control system.
Q98. What is the name of India’s indigenously built light combat helicopter?
[OSSC BSSO, 4 November 2022, Shift 2]
(A) Nag
(B) Trishul
(C) Prachand
(D) Agni
Answer: (C) Prachand
Explanation: Prachand is the indigenous Light Combat Helicopter developed by HAL. Designed to support combat in demanding terrain, it can operate at high altitude and carry weapons suited to armed helicopter missions. Specialised combat helicopters must combine manoeuvrability, payload, sensors and protection while operating close to ground threats.
Q97. Where is the headquarters of the Defence Research and Development Organisation?
[OSSC BSSO, 5 November 2022, Shift 3]
(A) New Delhi
(B) Bengaluru
(C) Pune
(D) Chennai
Answer: (A) New Delhi
Explanation: DRDO is headquartered in New Delhi under the Ministry of Defence. Established in 1958, it coordinates research across missiles, electronics, materials, aerospace and other technologies relevant to national defence.
Q96. From which country did India procure the S-400 air-defence missile system?
[OPSC ASO General Knowledge, 27 August 2022]
(A) France
(B) Russia
(C) United States
(D) Israel
Answer: (B) Russia
Explanation: India contracted for Russia’s S-400 Triumf system. It combines radars, command facilities and interceptors to engage different classes of aerial targets at substantial distances as part of layered air defence.
Q95. Which organisation contracted to supply Konkurs-M anti-tank guided missiles to the Indian Army?
[Gujarat Police SI, 6 March 2022]
(A) Tata Defence Systems
(B) DRDO
(C) Bharat Dynamics Limited
(D) ISRO
Answer: (C) Bharat Dynamics Limited
Explanation: Bharat Dynamics Limited is a defence public-sector undertaking specialising in missile and ammunition production. Konkurs-M is an anti-tank guided missile intended to attack armoured vehicles from ground platforms.
Q94. Pinaka, developed in India, is a:
[CDS II General Knowledge, 14 November 2021]
(A) Battle tank
(B) Multi-barrel rocket launcher
(C) Anti-tank guided missile
(D) Armoured utility vehicle
Answer: (B) Multi-barrel rocket launcher
Explanation: Pinaka is India’s indigenous multi-barrel artillery rocket system. Its launcher can fire several rockets rapidly, making it useful for delivering concentrated fire on battlefield areas rather than engaging one tank with a guided missile.
Q93. Which is India’s surface-to-surface ballistic missile with intercontinental-range capability?
[RRB NTPC CBT I, 19 January 2021, Shift 1]
(A) Agni-IV
(B) Shaurya
(C) Agni-V
(D) BrahMos
Answer: (C) Agni-V
Explanation: Agni-V is the longest-range operational member of India’s Agni family covered in this question. It is a strategic ballistic missile using solid propulsion; BrahMos is a different type of weapon, a cruise missile.
Q92. Which description fits the Prithvi-II missile tested in October 2018?
[RRB NTPC CBT I, 11 February 2021, Shift 1]
(A) Anti-tank guided missile
(B) Nuclear-capable long-range ballistic missile
(C) Ballistic missile
(D) Beyond-visual-range air-to-air missile
Answer: (C) Ballistic missile
Explanation: Prithvi-II is a short-range surface-to-surface ballistic missile developed by DRDO. Its trajectory and purpose differ from guided anti-tank weapons and air-to-air missiles; it belongs to the Prithvi strategic-missile family. This missile belongs to India’s early indigenous ballistic-weapons development, which helped establish the country’s strategic engineering base.
Q91. What was the nominal range of the Akash supersonic surface-to-air missile in the question?
[RRB NTPC CBT I, 16 February 2021, Shift 1]
(A) Around 20 km
(B) Around 25 km
(C) Around 35 km
(D) Around 30 km
Answer: (B) Around 25 km
Explanation: The original Akash surface-to-air system had an approximately 25-kilometre engagement range. Later variants may have different performance, so the answer refers to the version and specifications used in the examination. Surface-to-air interception also depends on radar detection, tracking information and coordination between the missile and its ground control system.
