Defence Current Affairs MCQs

Notes:
Kheybar Shekan Missile is a long-range solid-fuel ballistic missile developed by the Islamic Revolutionary Guard Corps (IRGC) of Iran. Recently, Iran claimed that IRGC used Kheybar Shekan missiles to target the office of Israeli Prime Minister Benjamin Netanyahu and an Israeli Air Force command centre. The missile belongs to the Khorramshahr missile family and represents an advanced generation of Iran’s missile system. It has an approximate range of about 1,450 kilometres, enabling strikes across much of the Middle East region. It uses solid fuel technology, which allows faster launch preparation, easier storage, and improved mobility.

Notes:
An Indian Armed Forces contingent arrived in Seychelles for the 11th edition of “Lamitiye 2026”, a joint military exercise with the Seychelles Defence Forces, held from March 9 to March 20 at the Seychelles Defence Academy. “Lamitiye”, meaning “friendship” in Creole, is a biennial exercise conducted since 2001 in Seychelles. All three Indian Armed Forces services are participating: Army (Assam Regiment), Navy (INS Trikand), and Air Force (C-130 aircraft). The 12-day exercise includes joint tactical drills, field training, combat discussions, case studies, lectures, and demonstrations, ending with a two-day validation exercise.

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 Indian Navy’s stealth frigate INS Nilgiri is participating in the Sea Phase of the Royal Australian Navy-hosted multinational Exercise KAKADU 2026 in Darwin, Australia. The exercise focuses on enhancing maritime interoperability, strengthening cooperation, and improving mutual understanding among participating nations. It serves as a key engagement for the Royal Australian Navy (RAN), bringing together numerous nations to promote maritime security. This participation highlights India’s commitment to building a secure, stable Indo-Pacific region through strengthened naval cooperation

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:
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:
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:
India has inducted its third nuclear-powered ballistic missile submarine, INS Aridhaman, into the Indian Navy, strengthening its strategic deterrence capability. INS Aridhaman is the third indigenously built Submersible Ship Ballistic Nuclear (SSBN) and the second submarine of the Arihant class (Submersible Ship Ballistic Nuclear). It has been developed under the Advanced Technology Vessel project (ATV) at the Ship Building Centre in Visakhapatnam. The submarine has a displacement of about 6,000 tonnes on the surface and 7,000 tonnes when submerged.

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.
