Defence Current Affairs MCQs

Notes:
The Precision Strike Missile (PrSM) was recently used by the United States for the first time in operations by United States Central Command during the conflict with Iran. It is a surface-to-surface guided ballistic missile designed to strike long-distance targets with very high precision. The missile is developed mainly for the United States Army by Lockheed Martin, a major US aerospace and defence company. It has an open system architecture and modular design, allowing upgrades and integration with new technologies.

Notes:
Defence Research and Development Organisation and the Indian Navy successfully conducted four in-flight release trials of the ADC-150 (Air Droppable Container-150) from the Boeing P-8I Poseidon near Goa. ADC-150 is an indigenously developed container capable of carrying 150 kg payload for aerial delivery. The parachute system was developed by Aerial Delivery Research and Development Establishment. Instrumentation support came from Defence Research and Development Laboratory. The system enables rapid aerial delivery of equipment, supplies and medical aid to naval ships operating in open sea or emergencies.

Notes:
Indian Navy hosted IMEX TTX 2026 (IONS Maritime Exercise Tabletop Exercise 2026) at Maritime Warfare Centre, Southern Naval Command, Kochi. It involved members of Indian Ocean Naval Symposium and international officers to discuss maritime security. Countries like Bangladesh, France, Indonesia, Kenya, Maldives, Mauritius, Myanmar, Seychelles, Singapore, Sri Lanka, Tanzania, and Timor-Leste participated. India assumes IONS Chairmanship (2026–2028) after 16 years.

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:
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:
INS Taragiri was commissioned into the Indian Navy on April 3, 2026, at Visakhapatnam by Defence Minister Rajnath Singh. It is the fourth ship of the Project 17A class, designed by the Warship Design Bureau. It was built by Mazagon Dock Shipbuilders Limited, it has over 75% indigenous content with MSME support. The frigate features advanced stealth technology with reduced radar cross-section. It supports multi-role operations: combat, surveillance, anti-piracy, and humanitarian missions.

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.

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:
INS Dhruv is India’s first dedicated nuclear missile tracking and ocean surveillance ship, enhancing strategic maritime capability. It was commissioned on 10 September 2021 and built by Hindustan Shipyard Limited (HSL) in collaboration with Defence Research and Development Organisation (DRDO) and National Technical Research Organisation (NTRO). The ship tracks ballistic missiles, gathers Electronic Intelligence (ELINT), and supports India’s missile defence programme. It provides early warning of missile threats and helps calibrate Ballistic Missile Defence (BMD) systems using trajectory data.

Notes:
INS Nireekshak reached Colombo to participate in IN–SLN DIVEX 2026 (India–Sri Lanka Navy Diving Exercise). It is a Diving Support and Submarine Rescue Vessel of the Indian Navy. The exercise (21–27 April 2026) focuses on diving operations, training, and interoperability. It strengthens maritime cooperation between India and Sri Lanka. The exercise aligns with MAHASAGAR (Mutual and Holistic Advancement for Security and Growth Across Regions) vision in the Indian Ocean Region.
