Practice questions
Q1Consider the following statements: 1. Pinaka is a multi-barrel rocket launcher system used for battlefield firepower rather than an Agni-like strategic ballistic missile family. 2. SMART is a simple anti-ship missile intended to strike surface vessels directly. Which one of the following is correct?
Statement 1 is correct: Pinaka is a multi-barrel rocket launcher associated with battlefield firepower. Statement 2 is incorrect because SMART extends anti-submarine reach by delivering a torpedo over standoff range; it is not a simple anti-ship missile.
Q2Match List I with List II: List I (System) 1. Akash 2. Nag 3. Astra 4. RudraM-II List II (Broad role) P. Air-to-surface missile Q. Anti-tank guided missile R. Surface-to-air air-defence system S. Air-to-air missile Select the correct answer using the code given below.
Akash is a surface-to-air air-defence system; Nag is an anti-tank guided missile; Astra is an air-to-air missile; and RudraM-II is an air-to-surface missile. Thus the complete matching is 1-R, 2-Q, 3-S and 4-P.
Q3With reference to the defence research and development ecosystem in India, consider the following statements: 1. DRDO is the research and development wing of the Ministry of Defence. 2. A successful developmental flight test by DRDO is identical to induction into service. 3. The Armed Services define operational requirements and participate in trials. Which of the statements given above are correct? Select the correct answer using the code given below.
Statements 1 and 3 are correct. DRDO develops defence technologies, while the Services state operational needs and join trials. A developmental test only establishes defined trial objectives; user evaluation, production and induction are separate stages. Hence statement 2 is incorrect.
Q4With reference to indigenisation and export of defence systems, consider the following statements: 1. Indigenous status may rest on Indian design authority, integration, critical software, key subsystems or the production base even when every component is not Indian. 2. Positive indigenisation lists identify items to be procured from domestic sources after specified dates. 3. Induction of a system for domestic use automatically authorises its export. Which of the statements given above are correct? Select the correct answer using the code given below.
Statements 1 and 2 are correct. Indigenisation can exist at several levels and need not imply that every component is Indian. Positive indigenisation lists require identified items to be sourced domestically after specified dates. Export remains subject to separate approval, end-use assessment, foreign policy and control-list status, so statement 3 is incorrect.
Q5With reference to missile flight and classification, consider the following statements: 1. A ballistic missile is powered during the boost phase and then follows a largely ballistic path under gravity. 2. A cruise missile remains powered for most of its flight. 3. BrahMos is classified as a ballistic missile because it is supersonic. Which of the statements given above are correct? Select the correct answer using the code given below.
Statements 1 and 2 are correct. A ballistic missile receives powered boost before following a largely ballistic trajectory, whereas a cruise missile is powered for most of its path. BrahMos is a supersonic cruise missile; speed alone does not make it ballistic, so statement 3 is incorrect.

8Consider the following statements regarding India's strategic export controls: 1. The updated SCOMET list of 2025 populates Category 7 with certain emerging technologies. 2. Export control prohibits every legitimate trade in advanced technology rather than permitting authorised trade. Which one of the following is correct?
