Defence Current Affairs MCQs

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:
The Indian Navy deployed a P-8I maritime patrol aircraft to Guam to join the US-led Sea Dragon anti-submarine warfare (ASW) exercise 2026. The exercise includes QUAD partners: United States, India, Australia, Japan, and also New Zealand. Multiple P-8 aircraft participate, enabling better coordination due to similar systems, sensors, and data-link capabilities. The drill improves ASW skills by training crews from simulated targets to real submarine detection with 200+ flight hours. Joint classroom sessions are also conducted to refine tactics and coordination. The deployment comes as India ensures safe passage of merchant ships in the Arabian Sea for energy security.

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:
Agray, an anti-submarine warfare shallow water craft, has been delivered to the Indian Navy. It is the fourth of eight ASW Shallow Water Crafts, aimed at strengthening coastal defence capabilities. The vessel is indigenously designed and built by Garden Reach Shipbuilders and Engineers. It is a reincarnation of the earlier INS Agray, a patrol vessel decommissioned in 2017. The ship has been constructed as per standards of the Indian Register of Shipping. It uses waterjet propulsion, making it among the largest Indian naval warships to use this technology. It is equipped with lightweight torpedoes, indigenous rocket launchers, and advanced shallow water SONAR systems for effective submarine detection.

Notes:
INS Dunagiri has been delivered to the Indian Navy as part of ongoing naval modernisation. It is the fifth ship of the Nilgiri-class (Project 17A) stealth frigates. The ship was designed by the Warship Design Bureau and built by Garden Reach Shipbuilding and Engineers. It is a reincarnation of the earlier INS Dunagiri, a Leander-class frigate that previously served in the Indian Navy. The vessel uses Combined Diesel or Gas (CODOG) propulsion, integrating a diesel engine and gas turbine driving controllable pitch propellers (CPP). It is equipped with a modern Integrated Platform Management System (IPMS) for efficient onboard operations.

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.

Notes:
The first edition of Exercise ‘Pragati’ is scheduled to take place at Umroi, Meghalaya, from May 18–31, 2026. Exercise Pragati (Partnership of Regional Armies for Growth and Transformation in the Indian Ocean Region) involves 11 friendly countries. It aims to enhance defence cooperation, interoperability, and mutual trust among participating nations. The exercise reflects a shared commitment to regional security and stability in the Indian Ocean Region.

Notes:
INS Mahendragiri is the sixth Nilgiri-class (Project 17A) stealth frigate delivered to the Indian Navy on 30 April 2026. It was constructed at Mazagon Dock Shipbuilders Limited in Mumbai, marking progress in indigenous warship building. Project 17A frigates are advanced multi-mission warships with improved stealth, survivability, and combat capabilities. The ship was designed by the Warship Design Bureau using an integrated construction approach. It uses Combined Diesel or Gas (CODOG) propulsion along with Controllable Pitch Propellers (CPP).
