Defence Current Affairs MCQs

Notes:
The United States has raised concerns about the capabilities of Iran’s Shahed attack drones. Shahed drones are low-cost, one-way-attack unmanned aerial vehicles developed by Iran. These drones are also called “kamikaze” or “suicide” drones as they explode on impact with their targets. The most widely used variants of Shahed drones are Shahed-131 and Shahed-136. Their low cost, low-altitude flight profile, and self-sacrificial nature have earned them the label “the poor man’s cruise missile.”

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:
The Indian Navy is set to commission INS Taragiri (F41), a stealth frigate, on 03 April 2026. It is the fourth ship of the Nilgiri-class (Project 17A), built by Mazagon Dock Shipbuilding Limited and designed by the Warship Design Bureau. The ship is a modern reincarnation of the earlier INS Taragiri (Leander-class frigate) and is built for high-speed, high-endurance, multi-dimensional naval operations.

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:
India is set to receive the remaining two units of the S-400 Triumf from Russia in 2026, completing the delivery under the deal. The system was procured under a $5.43 billion agreement signed in 2018 for five squadrons, out of which three are already inducted into the Indian Air Force. The S-400 is a modern long-range surface-to-air missile (MLR SAM) system developed by Russia. It can track and destroy multiple aerial targets at once within a range of up to 600 kilometres. The S-400 provides a powerful multi-layered air defence shield against threats like fighter jets, drones, cruise missiles, ballistic missiles, and stealth aircraft.

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:
The Tri-Service exercise “Dweep Shakti” was conducted jointly by the Indian Army, Indian Navy, and Indian Air Force from March 24 to March 28. The exercise aimed to validate integrated capabilities for rapid response in coastal and island defence operations. It involved coordinated amphibious assaults, maritime dominance operations, and complex beach landing drills. Advanced next-generation equipment and drones were used, highlighting improved precision and interoperability among the three services. The exercise helped refine integrated tactics, techniques, and procedures, strengthening multi-domain operational capability.

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:
Exercise Brahmastra, a major live-firing exercise by the Indian Army, was held at the Pokhran Field Firing Range in Jaisalmer, Rajasthan. The purpose of this exercise is to showcase the combat capabilities of the newly inducted AH-64E Apache attack helicopters and test coordination between air and ground forces. The Boeing AH-64 Apache is a multi-role attack helicopter equipped with a 30 mm chain gun, AGM-114 Hellfire missiles, and rockets for precision strikes. The exercise tested operational readiness, coordination between pilots and ground crews, and precision targeting in simulated battlefield conditions.
