Defence Current Affairs MCQs

Notes:
Yard 1280 (Shachi), the first of eleven Next Generation Offshore Patrol Vessels (NGOPVs), was launched at Goa Shipyard Limited (GSL), Goa on 31 March 2026. Construction of NGOPVs is happening concurrently at GSL, Goa and Garden Reach Shipbuilders & Engineers (GRSE), Kolkata. These indigenously built ships will augment the existing fleet of ten Offshore Patrol Vessels (OPVs)/Next-generation OPVs (NOPVs) for multi-domain operations including defence, surveillance, search and rescue, protection of offshore assets, Humanitarian Assistance & Disaster Relief (HADR), and anti-piracy missions.

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:
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:
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:
Tactical Advanced Range Augmentation (TARA) was developed by DRDO’s Research Centre Imarat along with other laboratories of the Defence Research and Development Organisation and Indian industry partners. DRDO and the Indian Air Force successfully carried out the maiden flight-trial of TARA off the coast of Odisha on 7 May 2026. TARA is India’s first indigenous glide weapon system designed to convert unguided warheads into precision-guided weapons. It is a modular range extension kit developed to improve the accuracy, range, and lethality of low-cost weapons against ground-based targets.

Notes:
INS Sagardhwani arrived in Vietnam as part of efforts to strengthen scientific and maritime cooperation. The vessel was flagged off for the 5th edition of the Sagar Maitri initiative. Sagar Maitri is a flagship collaborative programme of the Indian Navy and the Defence Research and Development Organisation aligned with the MAHASAGAR vision. MAHASAGAR stands for Mutual and Holistic Advancement for Security and Growth Across Regions. INS Sagardhwani is a specialised oceanographic research vessel commissioned in July 1994, designed by Naval Physical and Oceanographic Laboratory (NPOL) of DRDO and built by Garden Reach Shipbuilders & Engineers

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:
Sanghmitra was launched at Garden Reach Shipbuilders and Engineers in Kolkata under the Indian Navy’s indigenous shipbuilding programme. The vessel is part of the Indian Navy’s project to build 11 Next Generation Offshore Patrol Vessels (NGOPVs) at GRSE and Goa Shipyard Limited. These indigenously built ships will support maritime surveillance, coastal defence, anti-piracy patrols, search and rescue, and humanitarian assistance and disaster relief operations. The vessel is named after Sanghamitra, reflecting India’s cultural heritage.
