Defence Current Affairs MCQs

Notes:
Stealth frigate ‘Tavasya’ was launched at Goa Shipyard Limited (GSL) on March 22, 2025. It is the last of four Krivak-class stealth frigates and the second built at GSL under a technology transfer agreement with Russia. India and Russia signed an Inter-Governmental Agreement (IGA) in 2016 for four Krivak-class frigates. Two ships were imported from Russia, while two were built at GSL. Tavasya is likely the last warship built under foreign license as India moves towards indigenous warship production.

Notes:
The Indian Naval Sailing Vessel Tarini reached Cape Town, South Africa, in its final international stop of the Navika Sagar Parikrama II global circumnavigation. INSV Tarini is a 56-foot, indigenously built sailing vessel commissioned in February 2017 by the Indian Navy. It was built by Aquarius Shipyard Ltd., Goa, under the Make in India initiative. It has advanced navigation, satellite communication, and emergency steering for extreme conditions. It was named after the Tara-Tarini hill shrine in Odisha, historically revered by sailors. The expedition began on October 2, 2024, covering 23,400 nautical miles across three oceans and three major capes in eight months.

Notes:
Defence Research and Development Organisation (DRDO) and the Indian Army successfully conducted four flight-tests of the Army version of Medium-Range Surface-to-Air Missile (MRSAM) on April 3 and 4, 2025 from Dr APJ Abdul Kalam Island, Odisha. The tests involved intercepting high-speed aerial targets at long-range, short-range, high altitude, and low altitude, achieving direct hits and proving operational capability. The weapon system was tested in real conditions, and its performance was verified using radars and electro-optical tracking systems from the Integrated Test Range, Chandipur. The trials were conducted under DRDO’s guidance by the Indian Army’s Eastern and Southern Commands. MRSAM is jointly developed by DRDO and Israel Aerospace Industries and includes multi-function radar, command post, mobile launcher, and other vehicles. These trials pave the way for weapon system deployment in two Army Regiments.

Notes:
The Cabinet Committee on Security (CCS), led by the Prime Minister, approved a ₹63,000-crore deal to buy 26 Rafale-M fighter jets from France for the Indian Navy. Earlier, India planned to buy 126 jets under the Medium Multi-Role Combat Aircraft (MMRCA) tender in 2007, but it was cancelled in 2015. A 2016 deal brought 36 Rafale jets for the Indian Air Force (IAF), delivered from 2019 to 2022. The new deal includes 22 Rafale-M single-seater jets for aircraft carriers and 4 twin-seater trainers for practice. These jets will fly from INS Vikramaditya and INS Vikrant. Rafale is a 4.5 generation, twin-engine, delta-wing, multirole fighter made by Dassault Aviation. It can fly at Mach 1.8 and has a combat range of over 1000 kilometers, useful for various missions like air combat, ground attacks, and naval strikes.

Notes:
India recently showcased the BM-04 missile at the Vigyan Vaibhav 2025 defense exhibition in Hyderabad, highlighting its growing strength in conventional counterforce weapons. The BM-04 is a short-range ballistic missile (SRBM) developed by the Defence Research and Development Organisation (DRDO). It is 10.2 meters long, 1.2 meters in diameter, weighs 11,500 kg, and carries a 500 kg conventional warhead. With a range of 1,500 km and 30-meter circular error probability (CEP), it uses a two-stage solid-fuel system. It is canisterized and launched from a six-wheel indigenous transport erector launcher (TEL). It features a Common Hypersonic Glide Body (C-HGB) for evasive flight paths and can be upgraded regularly to face evolving threats.

Notes:
India successfully tested the Mk-II(A) Laser-Directed Energy Weapon (DEW), joining the US, China, and Russia as one of the few nations with this advanced technology. It is a 30-kilowatt laser-based weapon that can destroy helicopters, swarm drones, radars, and fixed-wing drones with high precision. It is developed by the Defence Research and Development Organisation (DRDO) and its lab Centre for High Energy Systems and Sciences (CHESS), Hyderabad, in collaboration with academic and industrial partners. It uses an Electro Optic (EO) system and radar to identify targets and fires a laser beam to cause structural failure in seconds. This system is fast, accurate, and helps avoid collateral damage, while also reducing the use of costly ammunition in combat.

Notes:
The European Union Naval Force (EUNAVFOR) under Operation ATALANTA has proposed a joint naval exercise with the Indian Navy. The exercise is planned to take place around the end of May 2025 in the Western Indian Ocean and the Red Sea. The main aim is to strengthen maritime cooperation and coordination between European forces and the Indian Navy. The proposal comes due to rising piracy and instability in the Red Sea region, especially near the Horn of Africa. Unlike regular Passage Exercises (PASSEX), this drill will include tactical manoeuvres, counter-piracy actions, and communication training. Operation ATALANTA, launched in 2008, is the European Union’s mission to fight piracy near Somalia.

Notes:
Indian Naval Ship (INS) Sunayna, deployed as part of Indian Ocean Ship (IOS) Security and Growth for All in the Region (SAGAR), arrived at Nacala Port in Mozambique. INS Sunayna is the second Saryu-class offshore patrol vessel of the Indian Navy. It was designed and built indigenously by Goa Shipyard Limited. The ship was commissioned on 15th October 2013 at Kochi and is based under the Southern Naval Command. It is meant for fleet support, coastal and offshore patrol, ocean surveillance, sea line monitoring, and escort duties. IOS SAGAR is a strategic Indian initiative to promote cooperation among navies and maritime agencies in the Southwest Indian Ocean Region.

Notes:
The Indian Air Force (IAF) is taking part in Exercise Desert Flag-10 from April 21 to May 8, 2025, at Al Dhafra Air Base in the United Arab Emirates (UAE). Exercise Desert Flag is a major multinational air combat exercise that trains different air forces under realistic war-like conditions. IAF has deployed two powerful aircraft: MiG-29, an air superiority fighter, and Jaguar, a deep strike ground attack aircraft. This year is special as it marks 50 years since the MiG-29 was first launched. Air forces from 12 countries, including the United States, United Kingdom, and France, are also participating. The goal is to share knowledge, improve tactics, and boost coordination in complex air combat missions.

Notes:
India has sent a second batch of batteries of the BrahMos missile system to the Philippines. BrahMos is a long-range supersonic cruise missile jointly developed by India and Russia. It can be launched from land, sea, and air platforms. It has a two-stage propulsion system. The first stage is a solid propellant booster that provides the initial supersonic speed. The second stage is a liquid ramjet that takes the missile close to a speed of 3 Mach during the cruise phase. It has a range of up to 290 kilometers. It uses “Fire and Forget” technology, which does not require further guidance after launch. It has shorter flight times, which means quicker target engagement and low dispersion.
