Defence Current Affairs MCQs

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 rising tensions between India and Pakistan after Operation Sindoor, civil defence mock drills named ‘Operation Abhyas’ are being held nationwide. These drills follow the recent terrorist attack in Pahalgam, Jammu and Kashmir, which raised national security concerns. ‘Operation Abhyas’ is part of broader civil defence steps directed by the Ministry of Home Affairs (MHA). The drills are being conducted in 244 civil defence districts across major cities like Delhi, Mumbai, Kolkata, Chennai, Bengaluru, Hyderabad, and Chandigarh.

Notes:
During a media briefing on Operation Sindoor, military officers showed an image of the Integrated Air Command and Control System (IACCS) node of the Indian Air Force (IAF). IACCS is an automated command and control system that combines data from all air defence assets. It is developed by Bharat Electronics Limited (BEL), a public sector company in aerospace and defence electronics. IACCS provides real-time updates and a unified dataset that helps military commanders at various levels. It offers a full and clear picture of the airspace, improving situational awareness during air operations.

Notes:
The Indian Army conducted the Teesta Prahar exercise today at the Teesta field firing range in West Bengal. This large-scale exercise involved various units like infantry, mechanised infantry, artillery, armoured corps, Para Special Forces, Army Aviation, Engineers, and Signals. It showcased the high level of coordination and joint force integration among different branches of the Indian Army. The aim was to demonstrate operational preparedness and combat-readiness in complex situations. The exercise is significant in the backdrop of Operation Sindoor, which focuses on strengthening India’s security along sensitive borders. Teesta Prahar reflects the Indian Army’s commitment to national defence and rapid response capability.

Notes:
Russia launched a massive air attack on Ukraine on June 11, 2025, using over 300 drones and missiles. Around 250 of these were Shahed drones, which are Iranian-made Unmanned Combat Aerial Vehicles (UCAVs). Shahed drones are also loitering munitions made by Shahed Aviation Industries for one-way explosive attacks. Russia calls the Shahed-136 drone “Geran-2”.

Notes:
The Defence Cyber Agency under Headquarters Integrated Defence Staff launched a cyber security exercise called ‘Cyber Suraksha’ on June 16, which will run till June 27. It is a multi-phase initiative to improve national-level cyber resilience. More than 100 participants from defence and national agencies are taking part in it. The exercise simulates real-world cyber threats in a gamified format to test and train participants. A Chief Information Security Officers (CISOs) conclave is also part of the exercise for leadership engagement.

Notes:
Recently, Israel deployed Barak Magen, also known as Lightning Shield, as a defense against Iranian drones. Barak Magen is an advanced naval air defense system developed by Israel Aerospace Industries (IAI). It is designed to counter various threats such as Unmanned Aerial Vehicles (UAVs), cruise missiles, high-trajectory projectiles, and shore-to-sea missiles. Barak Magen strengthens Israel’s layered defense architecture.

Notes:
Recently, Indian Navy commissioned INS Arnala, the first Anti-Submarine Warfare Shallow Water Craft (ASW-SWC), at the Naval Dockyard in Visakhapatnam. This marks a big step in strengthening India’s coastal defence and underwater threat response. INS Arnala is the first of sixteen ASW-SWC class ships and is designed for subsurface surveillance, search and rescue, and low-intensity maritime missions. It has over 80% indigenous content and reflects the vision of Aatmanirbhar Bharat (self-reliant India).

Notes:
Recently, the Indian Navy announced it will commission its new stealth multi-role frigate Tamal on 01 July 2025 at Kaliningrad, Russia. Tamal is part of the Krivak class frigates that India has been inducting from Russia over the last two decades. The name Tamal represents the mythical sword used by Indra, the King of the Gods, in battles. The frigate was built at Yantar Shipyard in Kaliningrad, Russia.

Notes:
Recently, the United States used up 15 to 20 percent of its Terminal High Altitude Area Defense (THAAD) missile system stock to defend against Iran’s aerial strikes during a 12-day conflict involving attacks on nuclear sites by Israel and the US. The THAAD system is an advanced missile defence developed by the United States to destroy short-, medium-, and intermediate-range ballistic missiles in their terminal phase. THAAD is a vital part of US Ballistic Missile Defense (BMD) and can intercept targets both inside and outside the atmosphere.
