Defence Current Affairs MCQs

Notes:
INS Trikand will participate in the 58th National Day celebrations of Mauritius, reflecting India–Mauritius maritime cooperation. It is a Talwar-class guided-missile frigate of the Indian Navy and the third and final ship of the second batch of this class. The ship was built at Yantar Shipyard, Kaliningrad in Russia and commissioned on 29 June 2013 at Kaliningrad. It operates under the Western Fleet of the Western Naval Command (WNC) headquartered at Mumbai.

Notes:
Iran deployed the Sejjil Ballistic Missile for the first time in active combat during Wave-54 operations against United States and Israel positions. Sejjil (also called Sajjil or Ashura) is an indigenously developed two-stage Medium-Range Ballistic Missile (MRBM) developed by Iran. It marks Iran’s shift from liquid-fuel missiles to solid-fuel technology, enabling faster launch and better reliability.

Notes:
The Indian Navy deployed a P-8I maritime patrol aircraft to Guam to join the US-led Sea Dragon anti-submarine warfare (ASW) exercise 2026. The exercise includes QUAD partners: United States, India, Australia, Japan, and also New Zealand. Multiple P-8 aircraft participate, enabling better coordination due to similar systems, sensors, and data-link capabilities. The drill improves ASW skills by training crews from simulated targets to real submarine detection with 200+ flight hours. Joint classroom sessions are also conducted to refine tactics and coordination. The deployment comes as India ensures safe passage of merchant ships in the Arabian Sea for energy security.

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 Army’s Southern Command conducted Exercise Amogh Jwala at the Babina Field Firing Ranges, Uttar Pradesh, to demonstrate high-tempo mechanised warfare capabilities. The exercise showcased the integrated use of advanced military assets, including attack helicopters, fighter aircraft, drones, counter-drone systems, and modern battlefield technologies. It was conducted in a multi-domain operational environment, combining land, air, cyber, and space elements to reflect modern warfare requirements. The drill emphasized synchronisation of fire and manoeuvre, along with real-time drone-enabled surveillance and target acquisition.

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 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:
Vayu Baan is India’s first helicopter-launched drone system developed by the Indian Air Force (IAF). It is a small, autonomous drone dropped from a moving helicopter mid-flight.After release, it unfolds wings, activates propulsion, and functions as surveillance (ISR) or precision-guided munition (kamikaze drone). The program is an indigenous Air-Launched Effects (ALE) project led by IAF’s Directorate of Aerospace Design (DAD). It aims to provide stand-off capability to identify and destroy targets beyond 50 km, keeping helicopters safe from MANPADS.

Notes:
Iran reportedly fired Qader cruise missiles targeting the USS Abraham Lincoln aircraft carrier, though reports indicate the ship was not hit. Qader is a medium-range, shore-based anti-ship cruise missile developed by Iran. It is an upgraded version of the Noor missile, which itself is based on the Chinese C-802 design. The missile strengthens Iran’s coastal defence and anti-access/area denial (A2/AD) capabilities in strategic regions like the Strait of Hormuz. It is part of Iran’s broader strategy to deter naval forces and protect its maritime interests.

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.
