Defence Current Affairs MCQs

Notes:
President Droupadi Murmu and Defence Minister Rajnath Singh attended Exercise Vayu Shakti. Exercise Vayu Shakti was held at Pokhran, Rajasthan. Indian Air Force showcased operational readiness, combat power and rapid response capability. Advanced systems like Akash, SpyDer, Short Range Loitering Munitions and Counter Unmanned Aerial Systems were demonstrated. Day, dusk and night operations showed versatility and high preparedness. Exercise highlighted success of Operation Sindoor and focus on Aatmanirbhar Bharat with indigenous platforms.

Notes:
The United States carried out strikes on Iranian targets using advanced weapons, including Tomahawk cruise missiles, stealth fighter jets, B-2 bombers, and low-cost one-way attack drones. Tomahawk is an United States of American (USA)-made long-range subsonic cruise missile used for deep land attack. It is launched from ships or submarines through a Vertical Launch System. It was first developed in the 1970s during the Cold War. It can carry a 1,000-pound conventional warhead or cluster munitions. It uses solid propellant at launch and later a turbofan engine, reducing infrared detection.

Notes:
Recently, Iran reportedly destroyed a key THAAD radar system used by the United States in the Middle East, affecting part of its missile-defence network. THAAD (Terminal High Altitude Area Defense) is an advanced ballistic missile defence system developed by the United States to counter missile threats. It is designed to intercept short, medium and limited intermediate-range ballistic missiles during the terminal phase, which is the final stage of their flight. The system can destroy incoming missiles both inside and outside Earth’s atmosphere, providing a high-altitude defence layer.

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 United States and South Korea conducted the joint military exercise “Freedom Shield” involving thousands of troops. Around 18,000 South Korean troops are participating, while the number of United States troops is not officially confirmed. The exercise continued till 19 March 2026 and focuses on defence preparedness and coordination. North Korea strongly opposes such exercises, viewing them as a rehearsal for invasion. These drills often trigger reactions from North Korea, including missile tests and military demonstrations.

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:
The Malwan has been delivered to the Indian Navy as part of efforts to strengthen coastal defence capabilities. It is the second of eight Anti-Submarine Warfare Shallow Water Crafts (ASW SWC) being built by Cochin Shipyard Limited at Kochi, and is indigenously designed and constructed. The vessel is named after Malwan and carries forward the legacy of the former INS Malwan, a naval minesweeper that served until 2003. It is designed for Anti-Submarine Warfare (ASW), coastal surveillance, Low Intensity Maritime Operations (LIMO), and mine warfare.

Notes:
Indian Air Force is preparing to induct unmanned stealth fighters under the Remotely Piloted Strike Aircraft (RPSA) programme. RPSA aims to develop Unmanned Combat Aerial Vehicle (UCAV) named Ghatak UCAV. Unmanned Combat Aerial Vehicles carry missiles and bombs for autonomous strike and combat operations. Ghatak features a stealthy flying-wing design for low radar detection. It can conduct deep-strike missions in heavily defended airspace without risking pilots.

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.

Notes:
The 4th edition of Exercise Cyclone IV between India and Egypt is scheduled to be held from 9 to 17 April 2026 at Anshas, Egypt. The exercise reflects growing defence cooperation between India and Egypt and follows the previous successful edition held in India. The Indian contingent consists of 25 personnel from Special Forces units, training alongside Egyptian Special Forces. The aim is to enhance joint mission planning and improve interoperability through exchange of best practices in special operations.
