Defence Current Affairs MCQs

Notes:
A new Maintenance, Repair, and Overhaul (MRO) facility will be set up in Bengaluru to support the C-130J Super Hercules aircraft, boosting India’s defence self-reliance. The C-130J Super Hercules is a four-engine turboprop military transport aircraft developed by Lockheed Martin of the United States of America (USA). It is the principal tactical cargo and personnel transport aircraft of the United States Air Force (USAF) and is the latest variant of the C-130 Hercules. The aircraft can operate from rough and dirt airstrips and is used for airdroppping troops and equipment in hostile areas.

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:
The Indian Army has declared 2026 as the ‘Year of Networking & Data Centricity’ to build a future-ready force. The focus is on stronger connectivity, real-time decision-making, and higher combat effectiveness. Jointness, self-reliance, and innovation are the core pillars of military power. Data centricity treats data as a key combat asset shared across platforms instantly. This enables faster targeting, efficient troop movement, and better resource use. It shifts the Army from platform-centric to network-centric warfare. The initiative supports indigenisation, defence modernisation, and seamless Army–Navy–Air Force operations.

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:
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:
The Indian Army has launched Depot Integration Management Edition, which is a pan-Army digital logistics platform. It provides near real-time visibility of logistic items from units up to Army Headquarters. It is developed jointly by the Indian Army and Bhaskaracharya National Institute for Space Applications and Geo-informatics. The platform standardises digital workflows across all Army depots and units. It equips commanders with integrated dashboards, exception alerts, and predictive stock analytics. It will reduce paperwork by about 70 percent and shorten the logistics cycle by one-third.

Notes:
Recently, INS Sagardhwani, India’s oceanographic research vessel under DRDO’s Naval Physical and Oceanographic Laboratory (NPOL), was flagged off for the fifth edition of the Sagar Maitri initiative from Southern Naval Command, Kochi. Sagar Maitri is a collaborative initiative of the Indian Navy and DRDO under MAHASAGAR, aiming to strengthen cooperation among Indian Ocean Rim (IOR) countries through socio-economic engagement and ocean research. The mission includes the MAITRI (Marine & Allied Interdisciplinary Training and Research Initiative) component for long-term scientific partnerships.

Notes:
The Indian Navy’s Sail Training Ship INS Sudarshini will undertake Lokayan 26, a 10-month transoceanic flagship expedition. INS Sudarshini is an indigenously built Sail Training Ship (STS) of the Indian Navy. It was constructed by Goa Shipyard Limited and is based at Kochi, Kerala, under the Southern Naval Command. The ship was commissioned on 27 January 2012. Such ships train sailors to survive independently at sea, handle rough weather, and develop core seamanship skills. INS Sudarshini is a three-masted barque capable of operating under sail or engine power.

Notes:
Defence Research and Development Organisation (DRDO) successfully demonstrated Solid Fuel Ducted Ramjet (SFDR) technology on February 3, 2026, from Integrated Test Range (ITR), Chandipur, Odisha. The demonstration positions India among elite nations with SFDR capability for long-range air-to-air missiles, providing a tactical advantage. The missile was initially propelled by a ground booster to reach the desired Mach number.
