Defence Current Affairs MCQs

Notes:
The Indian Army’s Southern Command, headquartered in Pune, successfully conducted the Akhand Prahaar exercise in the desert sector of Rajasthan under the tri-services exercise Trishul. The exercise validated the full-spectrum combat readiness of the Konark Corps through integrated use of all arms and services. It included mechanised and infantry manoeuvres, Special Heliborne Operations, and fighter ground attack missions by the Indian Air Force (IAF). The exercise demonstrated strong Army–Air Force coordination and joint operational excellence. It tested next-generation indigenous technologies, including drones, unmanned systems, counter-drone systems, and electronic warfare grids.

Notes:
The Chief of the Air Staff recently inaugurated the Mudh-Nyoma airbase in Ladakh by landing a C-130J aircraft there. Mudh-Nyoma is an Indian Air Force (IAF) base in southeastern Ladakh at 13,700 feet. It is just 23 km from the Line of Actual Control (LAC) with China. It is now the fourth IAF base in Ladakh, India’s highest airfield, and the world’s fifth highest. It lies near the southern bank of Pangong Tso and earlier had a mud landing strip. The Border Roads Organisation (BRO) began upgrading it in September 2023.

Notes:
The Naval Science & Technological Laboratory (NSTL), Visakhapatnam, under Defence Research and Development Organisation (DRDO), has developed a new generation of Man-portable Autonomous Underwater Vehicles (MP-AUVs). MP-AUVs are designed for mine countermeasure missions with Side Scan Sonar and underwater cameras as primary payloads for real-time detection and classification of Mine-Like Objects (MLOs). Deep learning-based target recognition algorithms enable autonomous classification, reducing operator workload and mission time. The system includes robust underwater acoustic communication for inter-AUV data exchange and improved situational awareness.

Notes:
India is set to strengthen counter-drone warfare as the Army and Indian Air Force plan to procure 16 indigenous Integrated Drone Detection and Interdiction System (Mark-2) units. The Mark-2 is developed by Defence Research and Development Organisation (DRDO), led by its lab CHESS – Centre for High Energy Systems & Sciences with the Armed Forces. It detects, tracks and neutralises hostile drones using sensors, jammers and high-energy laser weapons.

Notes:
Ukraine recently used US-supplied Army Tactical Missile System (ATACMS) missiles to strike targets inside Russia, marking an important development in the current conflict. Army Tactical Missile System (ATACMS) is a United States (US) made surface-to-surface ballistic missile series developed in the 1980s by Lockheed Martin. The missile was first used in the 1991 Persian Gulf War and is also operated by Bahrain, Greece, South Korea, Taiwan and the UAE. It is an all-weather, inertially guided ballistic missile with a 305 km range and single-stage solid propulsion.

Notes:
Infrastructure major Larsen & Toubro Limited (L&T) and BAE Systems (British Aerospace Engineering Systems) recently won an Indian Army contract to supply BvS10 Sindhu, a specialised all-terrain armoured vehicle. BvS10 Sindhu is an upgraded India-specific version of the BvS10 (Beowulf Vehicle System 10) used by Austria, France, the Netherlands, Sweden, Ukraine, and the United Kingdom. It is also ordered by the German Army and chosen for the Cold Weather All-Terrain Vehicle (CATV) programme of the United States Army. It has two connected vehicle sections that easily cross snow, marsh, mountains, and rough terrain.

Notes:
Bharat Electronics Limited and Safran Electronics and Defence (SED) signed a joint venture to produce the HAMMER Weapon System in India. HAMMER stands for Highly Agile and Manoeuvrable Munition Extended Range, developed by French company Safran. It is an air-to-ground precision-guided weapon system, also called a glide bomb. It has a range of up to 70 km and can be attached to 250 kg, 500 kg, and 1,000 kg standard bombs. It is resistant to jamming, can be launched from low altitudes, and works well over rough terrain.

Notes:
The Defence Research and Development Organisation (DRDO) conducted a successful high-speed rocket-sled test of a fighter aircraft escape system at controlled velocity. The test was carried out at the Rail Track Rocket Sled facility of the Terminal Ballistics Research Laboratory, Chandigarh. It validated canopy severance, ejection sequencing, and complete aircrew recovery using an instrumented Anthropomorphic Test Dummy. The test was conducted in collaboration with the Aeronautical Development Agency (ADA) and Hindustan Aeronautics Limited (HAL). A dual-sled system with LCA aircraft forebody was propelled using multiple solid propellant rocket motors.

Notes:
The Indian Navy announced that INS Aridhaman, India’s third Nuclear-Powered Ballistic Missile Submarine (SSBN), will soon be inducted. It is the second submarine of the Arihant class, built under the Advanced Technology Vessel (ATV) project at the Ship Building Centre, Visakhapatnam. It has a displacement of 6,000 tonnes on surface and 7,000 tonnes submerged, powered by an 83 Megawatt (MW) pressurized water reactor from Bhabha Atomic Research Centre (BARC). INS Arighaat is India’s second indigenously built Nuclear-Powered Ballistic Missile Submarine (SSBN), following the first SSBN INS Arihant.

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.
