Defence Current Affairs MCQs

Notes:
The United States conducted a test launch of the Minuteman III missile. Minuteman III is an intercontinental ballistic missile (ICBM) developed by United States. It is part of the US nuclear triad. It is a land-based nuclear missile under the US Air Force Global Strike Command. The missile uses three solid-propellant rocket motors and can reach speeds of about Mach 23 at burnout. It has a range of over 6,000 miles (5,218 nautical miles), enabling long-distance nuclear strike capability.

Notes:
The United States and South Korea conducted the joint military exercise “Freedom Shield” involving thousands of troops. Around 18,000 South Korean troops are participating, while the number of United States troops is not officially confirmed. The exercise continued till 19 March 2026 and focuses on defence preparedness and coordination. North Korea strongly opposes such exercises, viewing them as a rehearsal for invasion. These drills often trigger reactions from North Korea, including missile tests and military demonstrations.

Notes:
The NATO is deploying the U.S. Patriot Missile Defence System to the southern province of Adana to strengthen regional air defence capabilities. PATRIOT stands for Phased Array Tracking Radar to Intercept on Target. It is a ground-based, mobile missile defence system developed by the United States. The system is designed to detect, track, and intercept aerial threats with high precision.

Notes:
The Indian Army has started fielding Shaurya Squadrons, which are dedicated drone sub-units within armoured regiments. Shaurya Squadrons provide tank commanders with real-time surveillance and precision-strike capability at the unit level. Each squadron has 20 to 30 personnel trained in drone and counter-drone operations. They operate surveillance drones, attack drones, swarm drones, first-person view (FPV) drones, and loitering munitions.

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:
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:
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:
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:
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.
