Defence Current Affairs MCQs

Notes:
South Korean and United States air forces have started the Buddy Squadron joint aerial exercise at Osan Air Base in Pyeongtaek. The exercise aims to improve interoperability and integrated tactical skills between the two allies. Buddy Squadron is a battalion-level drill conducted alternately by South Korea and the United States. It focuses on sharing air-to-air combat tactics and integrated training. The exercise involves fourth- and fifth-generation fighter jets. It strengthens joint operational readiness and regional security cooperation.

Notes:
Prime Minister Narendra Modi and French President Emmanuel Macron virtually inaugurated the Final Assembly Line (FAL) for H125 helicopters at Vemagal Industrial Area in Kolar district, Karnataka (near Bengaluru). The facility marks India’s first private-sector helicopter manufacturing plant. It will manufacture the H125 helicopter. Initial production capacity: 10 helicopters per year, scalable to meet a projected demand of 500 units over 20 years. The first “Made in India” H125 is expected to roll out by early 2027. The H125 is globally known for its “hot and high” performance, including the record landing on Mount Everest.

Notes:
The Integrated Fire and Manoeuvre Exercise Agni Varsha was conducted at Pokhran Field Firing Range, Jaisalmer, Rajasthan, by the Southern Command of the Indian Army. The exercise highlighted combat effectiveness of mechanised forces operating across multiple domains. Foreign defence journalists from 25 countries witnessed the exercise, observing speed, accuracy, and synchronisation of Combined Arms formations in the Thar Desert. Agni Varsha incorporated modern battlefield technologies: unmanned aerial systems, counter-drone measures, precision strike rockets, artillery platforms, and networked surveillance assets.

Notes:
Prime Minister’s second state visit to Israel focuses on defence cooperation and acquiring Sky Sting missile for Indian Air Force (IAF). Sky Sting is a 6th-generation Beyond-Visual-Range Air-to-Air Missile (BVRAAM). It is developed by Rafael Advanced Defense Systems Limited, an Israeli defence technology company. It is lightweight and can be fitted on Tejas Mk1A and Sukhoi-30MKI fighter jets. It has a strike range of about 250 kilometres. It uses a three-pulse solid-fuel rocket motor and can reach speeds above Mach 5.

Notes:
Recently, the President of India undertook a sortie in the indigenous Light Combat Helicopter (LCH) Prachand at Air Force Station Jaisalmer, Rajasthan. It is an indigenously developed Light Combat Helicopter made by Hindustan Aeronautics Limited. It is the only attack helicopter in the world capable of landing and taking off at 5,000 metres (16,400 feet). It has advanced stealth features, armoured protection and night attack capability. It has crash-resistant landing gear for better survivability. It reduces radar and Infrared (IR) signature and has a countermeasure dispensing system against enemy missiles.

Notes:
The United States conducted a test launch of the Minuteman III missile. Minuteman III is an intercontinental ballistic missile (ICBM) developed by United States. It is part of the US nuclear triad. It is a land-based nuclear missile under the US Air Force Global Strike Command. The missile uses three solid-propellant rocket motors and can reach speeds of about Mach 23 at burnout. It has a range of over 6,000 miles (5,218 nautical miles), enabling long-distance nuclear strike capability.

Notes:
Sheshnaag-150 is a long-range swarm attack drone being developed in India for deep-strike military missions. It is being developed by NewSpace Research and Technologies (NRT), which focuses on Artificial Intelligence (AI)-based unmanned systems and swarm robotics. It is a collaborative swarm drone, meaning multiple drones can coordinate autonomously to carry out saturation attacks on targets. The drone weighs around 150 kg and can carry 25–40 kg payload, including explosive warheads capable of damaging infrastructure or military vehicles.

Notes:
The Indian Navy’s stealth frigate INS Nilgiri is participating in the Sea Phase of the Royal Australian Navy-hosted multinational Exercise KAKADU 2026 in Darwin, Australia. The exercise focuses on enhancing maritime interoperability, strengthening cooperation, and improving mutual understanding among participating nations. It serves as a key engagement for the Royal Australian Navy (RAN), bringing together numerous nations to promote maritime security. This participation highlights India’s commitment to building a secure, stable Indo-Pacific region through strengthened naval cooperation

Notes:
India is set to receive the remaining two units of the S-400 Triumf from Russia in 2026, completing the delivery under the deal. The system was procured under a $5.43 billion agreement signed in 2018 for five squadrons, out of which three are already inducted into the Indian Air Force. The S-400 is a modern long-range surface-to-air missile (MLR SAM) system developed by Russia. It can track and destroy multiple aerial targets at once within a range of up to 600 kilometres. The S-400 provides a powerful multi-layered air defence shield against threats like fighter jets, drones, cruise missiles, ballistic missiles, and stealth aircraft.

Notes:
Rajnath Singh laid the foundation of the Large Cavitation Tunnel (LCT) at Naval Science and Technological Laboratory (NSTL) in Visakhapatnam. NSTL is a premier lab under the Defence Research and Development Organisation (DRDO). The Large Cavitation Tunnel (LCT) is a strategic facility for advanced hydrodynamic research and testing of naval systems. It will enable indigenous design, development, and testing of ships, submarines, and propulsion systems. It supports stealth, noise reduction, and next-generation underwater technologies. The facility allows both closed-loop (submarine) and free-surface (surface ship) simulations.
