Defence Current Affairs MCQs

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 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:
Russia warned Germany that if Ukraine uses Taurus missiles, it will be seen as direct involvement in the ongoing war. The Taurus KEPD-350 is a long-range cruise missile launched from aircraft. It is capable of hitting fortified and high-value targets with high precision. The missile was jointly developed by MBDA (Matra BAE Dynamics Alenia) and Saab Bofors Dynamics from Germany and Sweden. It is specially designed for deep strikes on bunkers, bridges, and command centres. This warning reflects growing tensions over Western military support to Ukraine in the conflict.

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:
The Russian Ministry of Defence has, for the first time, acknowledged the threat from Ukraine’s new short-range ballistic missile called Sapsan. The Sapsan, also known as Hrim-2 or Grom-2, is a tactical ballistic missile system developed by Ukraine. It combines features of both a tactical missile system and a multiple rocket launcher for flexible battlefield use. The export version of the Hrim-2 missile is capable of hitting fixed targets, both individual and group-based. Its range varies from 50 to 280 kilometers, making it effective for short-range precision strikes.

Notes:
Australia will host Exercise Talisman Sabre from 13 July to 4 August 2025, the largest edition to date. Talisman Sabre is the largest bilateral combined training activity between the Australian Defence Force and the United States military. Partner nations include Canada, Fiji, France, Germany, India, Indonesia, Japan, the Netherlands, New Zealand, Norway, Papua New Guinea, the Philippines, the Republic of Korea, Singapore, Thailand, Tonga, and the United Kingdom. Brunei, Malaysia, and Vietnam will attend as observers. The 2025 edition will focus on multi-domain warfighting, with key activities in land, air, sea, space, and cyber domains.

Notes:
Defence Research and Development Organisation (DRDO) has successfully conducted the first flight trial of the Stratospheric Airship Platform in Sheopur, Madhya Pradesh. The platform was developed by DRDO’s Aerial Delivery Research and Development Establishment (ADRDE) based in Agra. The airship carried an instrumental payload and reached a high altitude of about 17 kilometres. The total flight lasted 62 minutes and helped gather important data through onboard sensors. This data will help in building accurate simulation models for future high-altitude missions. The test also checked the envelope pressure control and emergency deflation systems, and the airship was safely recovered.

Notes:
Iran recently unveiled a new solid-fuel ballistic missile named Ghassem Basir. It is a Medium-Range Ballistic Missile (MRBM) developed to strike targets over 1,200 kilometers away. The missile is about 11 meters long and weighs around 7 tons. It uses carbon fiber composite material for its body, making it lighter and harder to detect by radar. It runs on solid fuel, making it quicker to launch and easier to store than liquid-fuel missiles. It can reach speeds up to Mach 12. A thermal imaging sensor helps it track targets using heat in the final phase of flight. It has a Maneuverable Reentry Vehicle (MaRV) that detaches mid-flight to avoid radar and improve accuracy. It can be launched from mobile Transporter-Erector-Launchers (TELs), even from vehicles that look like civilian trucks.

Notes:
Defence Research and Development Organisation (DRDO) and Indian Navy successfully carried out combat firing of the Multi-Influence Ground Mine (MIGM) with reduced explosives. MIGM is an advanced underwater naval mine developed by Naval Science and Technological Laboratory, Visakhapatnam, with support from other DRDO labs. It is designed to target stealth ships and submarines, enhancing the Indian Navy’s underwater combat strength. The mine has intelligent systems with ARM processor-based electronics that process sensor data in real time for precise defence action. Bharat Dynamics Limited and Apollo Microsystems Limited are the production partners. The system will strengthen India’s coastal defence and underwater deterrence.

Notes:
In response to the recent terror attack in Pahalgam and rising tensions with Pakistan, the Indian Navy is enhancing its maritime strength by inducting INS Tamal. INS Tamal is a stealth guided missile frigate with advanced features designed for modern naval warfare. It is an upgraded Krivak-III class warship built under a $2.5 billion India-Russia defence deal for four stealth frigates. Two of these frigates are being built in Russia, and the other two at Goa Shipyard Limited in India. INS Tushil, the first warship of this class, joined the Indian Navy in December 2024. INS Tamal will be the last imported warship, marking India’s shift to building its own warships. The remaining two frigates, INS Triput and INS Tavasya, are being constructed in India under a technology transfer agreement worth around Rs 13,000 crore.
