Defence Current Affairs MCQs

Notes:
The Defence Research and Development Organisation (DRDO) successfully completed User Evaluation Trials of the Akash Next Generation (Akash-NG) missile system. Akash-NG is a modern Surface-to-Air Missile (SAM) defence system developed by DRDO and produced by Bharat Dynamics Limited (BDL). It is designed to protect vital areas from enemy air attacks. It is the advanced successor of the Akash missile. The new version is lighter and more advanced. It uses an indigenous Radio Frequency (RF) seeker, dual-pulse solid rocket motor, and fully indigenous radars with Command, Control, and Communication (C2) systems.

Notes:
The Indian Coast Guard conducted the Regional Level Pollution Response Exercise 2025 (RPREX-2025) in Mumbai. The exercise focused on tackling oil pollution at sea. A mock scenario involved a Motor Tanker sending a distress call after a collision with a fishing boat. The collision caused a hole in the tanker and heavy crude oil spillage into the sea. A specialised Indian Coast Guard Pollution Control Vessel and two other ships were deployed. Ships operated in full pollution response configuration. The exercise tested coordination and readiness of all stakeholders. It was conducted as per the National Oil Spill Disaster Contingency Plan.

Notes:
Exercise DESERT CYCLONE–II concluded at Al-Hamra Training City, Abu Dhabi, from 18–30 December. It was a joint military exercise between the Indian Army and UAE Land Forces, strengthening defence partnership and regional security. Training combined classroom instruction and field exercises, focusing on urban operations and sub-conventional operations under a United Nations mandate. Troops practiced urban combat, building clearance, IED awareness, casualty evacuation, first aid, heliborne operations, air assault missions, and platoon-level assaults. The exercise enhanced interoperability, operational synergy, and standardisation of tactics for future multinational operations.

Notes:
The Ministry of Defence signed defence contracts worth ₹4,666 crore to strengthen the Indian Army and Indian Navy. The deal includes Close Quarter Battle Carbines for both forces and Heavyweight Torpedoes for the Indian Navy. The Close Quarter Battle Carbine is a 56 × 45 millimetre compact firearm made under Indigenous Design, Development and Manufacturing. It is designed by the Defence Research and Development Organisation’s (DRDO’s) Armament Research and Development Establishment, Pune. It is manufactured by Bharat Forge Limited, a Pune-based Indian multinational company.

Notes:
A rare U.S. Air Force RQ-170 “Sentinel” stealth surveillance drone was recently spotted returning to Roosevelt Roads Naval Station in eastern Puerto Rico. The drone returned after U.S. military strikes conducted overnight against targets in Venezuela. The RQ-170 Sentinel is a high-altitude, long-endurance unmanned aerial vehicle (UAV) of the United States. It was designed and manufactured by Skunk Works, a division of Lockheed Martin, for the United States Air Force (USAF). The drone is used for intelligence, surveillance, target acquisition, reconnaissance (ISTAR), and electronic warfare missions over target areas.

Notes:
Gulf Cooperation Council (GCC) forces have launched a major joint military exercise in Saudi Arabia called “Gulf Shield 2026”. The exercise aims to strengthen collective defence and improve regional military coordination among all GCC member states. It is designed to enhance combat readiness, joint operational integration, and efficiency in planning and execution in a unified operational environment. The drills include a wide range of procedures, tests, and field scenarios to assess force readiness and effectiveness of responses to potential threats.

Notes:
India’s indigenous Long Range Anti-Ship Missile (LRAShM) will be showcased at the Republic Day parade on 26 January. LRAShM is a hypersonic glide missile developed by the Defence Research and Development Organisation (DRDO). Hypersonic glide vehicles (HGVs) like LRAShM glide unpredictably after rocket launch, unlike traditional ballistic missiles. The missile combines extreme speed and maneuverability, making it hard to intercept with current air defenses.

Notes:
The Boeing E-4B Nightwatch, also called the US military’s “Doomsday Plane,” recently made a rare appearance in Los Angeles, causing panic amid high geopolitical tensions. It is the most secretive aircraft in the US military and serves as the National Airborne Operations Center. The plane functions as a flying command post to keep the US government operational during extreme scenarios like nuclear war or destruction of ground command centers. Its mission is to ensure government continuity even in “doomsday” situations. The E-4B is a key part of the Nuclear Command, Control, and Communications system (NC3), allowing senior leaders to manage nuclear forces under all conditions.

Notes:
India will debut its Long-Range Anti-Ship Hypersonic Glide Missile (LR-AShM) at the 77th Republic Day parade, marking entry into the hypersonic anti-ship weapons club. LR-AShM is an indigenous missile developed by the Defence Research and Development Organisation (DRDO) for the Indian Navy. It is designed to destroy high-value naval targets like aircraft carrier battle groups at very long ranges. The missile enhances maritime deterrence in the Indian Ocean Region (IOR) and strengthens Anti-Access/Area Denial (A2/AD) capability.

Notes:
India and France are discussing a major deal to procure SCALP cruise missiles after their successful use by the Indian Air Force (IAF) in precision strikes during Operation Sindoor. SCALP, also called Storm Shadow, is a long-range, air-launched cruise missile developed jointly by France and the United Kingdom. It is used by several North Atlantic Treaty Organization (NATO) and allied air forces.
