Defence Technology & Missiles — Preparation
This question tests your understanding of Defence Technology & Missiles, a key topic in the General Knowledge section. The detailed solution above uses a step-by-step approach to show the reasoning, and where available, a shortcut that helps you solve similar questions in under 90 seconds during the actual exam.
This topic covers India's defence technology: the missiles developed under the Integrated Guided Missile Development Programme and later, their types and ranges, DRDO, defence equipment such as aircraft, tanks, submarines and warships, and military exercises with other countries. Common questions ask what type a missile is (Prithvi is surface-to-surface, Akash is surface-to-air, and Nag is anti-tank), which missile was developed with Russia (BrahMos), and which countries take part in a joint exercise. Lists of exercises and newly inducted equipment change often, so check current affairs as well. Practise the defence technology and missiles questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
