Defence Current Affairs MCQs

Notes:
America’s Anduril and the United Arab Emirates (UAE) EDGE Group are jointly developing the new Omen drone at a 50,000 sq ft research centre in Abu Dhabi as per the recent update. Omen is a tail-sitting vertical takeoff and landing drone with a hybrid-electric propulsion system. It is modular and adaptable for both military and non-military missions. It supports roles like maritime surveillance, infrastructure protection, and persistent Intelligence, Surveillance and Reconnaissance (ISR) over coastal areas.

Notes:
The Ministry of Defence recently signed a deal with Bharat Dynamics Limited (BDL) to procure INVAR Anti-Tank Missiles worth over ₹2,095 crore to strengthen T-90 tank firepower. INVAR is an Anti-Tank Guided Missile (ATGM) fired from the barrel of T-90 tanks. It offers long-range precision strikes and can destroy tanks with Explosive Reactive Armour (ERA). It is built by Russia’s Rosoboronexport and produced in India under licence by Bharat Dynamics Limited (BDL). It uses semi-automatic laser beam-riding guidance, making it resistant to jamming.

Notes:
Recently, France released images of its new nuclear-capable supersonic cruise missile, the Air-Sol Moyenne Portée-Renove (ASMPA-R), for the first time. ASMPA-R was developed by France as the latest version of the ASMP medium-range missile family. It is a crucial part of France’s nuclear deterrence and supports the air-based leg of its nuclear triad. It uses a ramjet engine with dual air intakes for sustained supersonic flight at about Mach 3.

Notes:
Indian Naval Ship (INS) Sahyadri took part in the bilateral maritime exercise AUSINDEX 2025 in the Northern Pacific. AUSINDEX is held between India and Australia and has been conducted biennially since 2015.

Warships and aircraft of both navies carried out joint operations including anti-submarine warfare, gunnery drills, and advanced flying operations. INS Sahyadri participated from India and HMAS Ballarat participated from Australia.

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:
Exercise Harimau Shakti 2025 is a joint military exercise conducted between India and Malaysia at the Mahajan Field Firing Range in Rajasthan from 5–18 December 2025.

INS Gharial (L23) is a Magar-class amphibious warfare ship of the Indian Navy designed for transporting troops, vehicles, and equipment for amphibious operations. It is the second indigenously built Landing Ship Tank (Large), highlighting India’s growing shipbuilding capabilities. The ship was constructed by Hindustan Shipyard Limited (HSL) and Garden Reach Shipbuilders and Engineers (GRSE). INS Gharial is among the largest ships of the Indian Navy and is part of the Eastern Fleet under the Eastern Naval Command.

Notes:
In response to the growing threat from sub-sonic cruise missiles, the Indian Army is undertaking a significant strategic shift by repurposing its Man-Portable Air Defence Systems (MANPADS) to strengthen low-altitude air defence capabilities. This move reflects the Army’s focus on countering modern aerial threats that fly low, evade radar, and target critical military and civilian infrastructure. MANPADS are portable surface-to-air missile systems that can be operated by an individual soldier or a small team to engage aerial targets. These systems are commonly known as shoulder-fired anti-aircraft missiles, enhancing battlefield mobility and rapid deployment.

Notes:
