Defence Current Affairs MCQs

Notes:
The United States has raised concerns about the capabilities of Iran’s Shahed attack drones. Shahed drones are low-cost, one-way-attack unmanned aerial vehicles developed by Iran. These drones are also called “kamikaze” or “suicide” drones as they explode on impact with their targets. The most widely used variants of Shahed drones are Shahed-131 and Shahed-136. Their low cost, low-altitude flight profile, and self-sacrificial nature have earned them the label “the poor man’s cruise missile.”

Notes:
Recently, Israel reportedly used the Blue Sparrow missile in a strike in Tehran, targeting Ali Khamenei, the Supreme Leader of Iran. The Blue Sparrow missile is part of an air-launched ballistic missile family that also includes the Black Sparrow missile and Silver Sparrow missile. It is developed by Rafael Advanced Defense Systems, an Israeli defence technology company. The missiles were originally designed as target missiles for testing the Arrow missile defence system of Israel. Later, the Blue Sparrow was modified into an offensive air-to-surface missile. It is about 6.5 metres long and weighs around 1.9 tonnes. The missile is usually launched from fighter aircraft such as F-15 jets, which boost it to high altitude.

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:
INS Trikand will participate in the 58th National Day celebrations of Mauritius, reflecting India–Mauritius maritime cooperation. It is a Talwar-class guided-missile frigate of the Indian Navy and the third and final ship of the second batch of this class. The ship was built at Yantar Shipyard, Kaliningrad in Russia and commissioned on 29 June 2013 at Kaliningrad. It operates under the Western Fleet of the Western Naval Command (WNC) headquartered at Mumbai.

Notes:
Vayu Baan is India’s first helicopter-launched drone system developed by the Indian Air Force (IAF). It is a small, autonomous drone dropped from a moving helicopter mid-flight.After release, it unfolds wings, activates propulsion, and functions as surveillance (ISR) or precision-guided munition (kamikaze drone). The program is an indigenous Air-Launched Effects (ALE) project led by IAF’s Directorate of Aerospace Design (DAD). It aims to provide stand-off capability to identify and destroy targets beyond 50 km, keeping helicopters safe from MANPADS.

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:
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:
Recently, Hindustan Aeronautics Limited handed over four ALH Mk III Maritime Role helicopters to the Indian Coast Guard, boosting maritime capabilities. ALH Mk III is the maritime variant of the indigenous Dhruv Advanced Light Helicopter. It is indigenously designed and manufactured in India, supporting self-reliance in defence. It is a multi-role, twin-engine helicopter suited for complex maritime operations. It enhances operational readiness, rapid response, and surveillance efficiency of the Indian Coast Guard.

Notes:
India plans to equip Dassault Mirage 2000 jets with Astra Mark-2 missiles, enhancing interception up to 240 kilometres and boosting aerial dominance. Astra Mark-2 is a Beyond Visual Range (BVR) air-to-air missile, developed by the Defence Research and Development Organisation (DRDO). More than 50 industries, including Hindustan Aeronautics Limited (HAL), contributed to its development. Astra Mark-1 (90–100 kilometres range) is already inducted in the Indian Air Force (IAF) on LCA Tejas and Su-30 MKI.

Notes:
The Ministry of Home Affairs received an indigenous satellite imaging system Prajna, developed by Defence Research and Development Organisation through CAIR (Centre for Artificial Intelligence and Robotics), to improve real-time decision-making for security agencies. The AI-enabled Prajna system is designed to monitor sensitive regions and support counter-terrorism operations, thereby strengthening internal security. DRDO and the Indian Navy successfully conducted in-flight trials of ADC-150 (Air Droppable Container with 150 kg capacity) from the P-8I aircraft off the Goa coast.
