Defence Current Affairs MCQs

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:
Indian Navy’s offshore patrol vessel INS Sunayna arrived at Malé, Maldives, under the Indian Ocean Ship (IOS) SAGAR initiative, strengthening India–Maldives maritime ties. The ship was welcomed by Maldives National Defence Force, with two MNDF personnel onboard as part of the multinational crew. This initiative aligns with “Neighbourhood First” policy and Mutual and Holistic Advancement for Security and Growth Across Regions (MAHASAGAR) vision. It highlights India’s commitment to regional security, interoperability, and maritime cooperation.

Notes:
Balikatan Exercise is the largest bilateral military drill between the Armed Forces of the Philippines and the United States Armed Forces. The term “Balikatan” means “shoulder-to-shoulder,” symbolising the strong alliance between the Philippines and the United States. It is conducted annually, with the first edition held in 2001. The 2026 exercise (41st edition) will be held from 20 April to 8 May 2026. Around 17,000 troops from seven countries—Philippines, USA, Australia, Japan, Canada, France, and New Zealand—will participate. The exercise aims to enhance regional security through joint operations and interoperability.

Notes:
Russia has approved the sale of the R-37M (Russian long-range air-to-air missile), also known as AA-13 Axehead (North Atlantic Treaty Organization reporting name), to India to enhance its air combat capability. The missile is designed for BVR (Beyond Visual Range) combat, allowing it to strike targets at very long distances without direct visual contact. It is developed to destroy enemy fighter jets, drones, and other aerial threats effectively. The missile is nicknamed an “AWACS (Airborne Warning and Control System) Killer” because it can target high-value aircraft like radar planes, refuelling tankers, and jamming systems.

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 Indian Army contingent has reached Cambodia for the second edition of the India–Cambodia joint military exercise CINBAX-II 2026. The exercise is held at Techo Sen Phnom Thom Mreas Training Centre in Kampong Speu Province, Cambodia from May 4 to 17, 2026. Around 120 Indian personnel, mainly from the Maratha Light Infantry Regiment, are participating. The Cambodian side is represented by about 160 personnel from the Royal Cambodian Army. The exercise is conducted under the framework of Chapter VII of the United Nations mandate. It focuses on counter-terrorism operations in sub-conventional and semi-urban environments.

Notes:
India successfully conducted the second flight trial of the Divyastra Missile from Dr. APJ Abdul Kalam Island, Odisha. Divyastra is an advanced Agni missile equipped with Multiple Independently Targeted Re-entry Vehicle (MIRV) technology. It was developed by India’s Defence Research and Development Organisation (DRDO). MIRV technology enables a single missile to carry multiple nuclear warheads that can strike different targets independently. MIRV technology was first developed by the United States in the 1960s.

Notes:
Saanya became the first woman officer in the Indian Air Force (IAF) to receive the prestigious Category-A Qualified Flying Instructor Certification (Cat-A QFI). Cat-A QFI is the highest instructional grading in the IAF and is awarded to highly skilled and experienced pilots authorised to train junior instructors and evaluate advanced combat flying skills.
Squadron Leader Saanya was commissioned into the IAF Flying Branch on June 20, 2015.

Notes:
Exercise PRAGATI 2026 began at Umroi Military Station, Meghalaya, with participation from 12 friendly nations, including Bhutan, Indonesia, Nepal, Sri Lanka, Vietnam, and the Philippines. PRAGATI stands for “Partnership of Regional Armies for Growth and Transformation in the Indian Ocean Region.” The exercise is organised by the Indian Army to strengthen regional military cooperation, defence ties, and intelligence-sharing mechanisms. The two-week exercise focuses on counter-terrorism operations in semi-mountainous and jungle terrain.

Notes:
Recently, the U.S. military used a Hellfire missile against a tanker heading toward Iran. The AGM-114 Hellfire is a short-range, air-to-ground, subsonic tactical missile developed by Lockheed Martin, United States. It entered service in 1984 and was originally designed as an anti-tank weapon. The missile can also be used against helicopters and slow-moving aircraft. It is deployed from platforms such as AH-64 Apache helicopters, MQ-1 Predator, MQ-9 Reaper drones, fighter aircraft, and ground launchers. The Hellfire missile is used by the United States and around 30 allied countries.
