Defence Current Affairs MCQs

Notes:
The Indian Army recently conducted Exercise Drone Prahar at Rayang military station in East Siang district of Arunachal Pradesh. It is a high-tech military drill to validate the use of drone technology in tactical battlefield operations. The exercise focused on using drones for Intelligence, Surveillance, and Reconnaissance (ISR) missions. It tested real-time sensor-to-shooter coordination and precision targeting capabilities. The goal was to boost command reach and situational awareness for tactical commanders.

Notes:
Recently, the Indian Army conducted a high-altitude tech demonstration exercise named ‘Divya Drishti’ in East Sikkim in July 2025. The exercise was aimed at enhancing battlefield awareness, surveillance, and fast decision-making. It was led by the Trishakti Corps and involved real-time use of ground platforms, Unmanned Aerial Vehicles (UAVs), and drones in realistic scenarios. A key highlight was the integration of Artificial Intelligence (AI)-enabled sensors with secure communication networks.

Notes:
Defence Research & Development Organisation (DRDO) conducted two successful flight-tests of Pralay missile on July 28 and 29, 2025, from Dr APJ Abdul Kalam Island, Odisha. Pralay is an indigenously-developed quasi-ballistic missile with advanced guidance and navigation for high precision. It is developed by Defence Research and Development Organisation (DRDO). It uses solid propellant and can be launched from a mobile launcher. The missile has a range of 150 to 500 kilometers.

Notes:
The United States military unveiled a mockup of China’s HQ-16 missile at the Experimental Aircraft Association ‘AirVenture Show’ in Oshkosh, Wisconsin. HQ-16 is a Chinese Surface-to-Air Missile (SAM) system with NATO name CH-SA 16. It is based on Russia’s Buk missile family. It is designed to target aircraft, cruise missiles, helicopters, and unmanned aerial vehicles (UAVs). It uses a vertical launch system for 360-degree coverage in complex terrains.

Notes:
Indian Naval Ships INS Rana and INS Jyoti took part in the 12th edition of Sri Lanka–India Naval Exercise (SLINEX-25). SLINEX is a bilateral naval exercise between India and Sri Lanka, started in 2005. It has enhanced maritime cooperation and interoperability for nearly two decades. The last edition was held in Visakhapatnam, India, in 2024. SLINEX-25 is conducted in two phases – Harbour phase and Sea phase. Harbour phase includes Subject Matter Expert Exchange (SMEE), cultural programs, yoga, sports, and best practice sharing. Sea phase covers gunnery firing, navigation, seamanship, fueling at sea, communication, and Visit Board Search and Seizure (VBSS).

Notes:
The Indian Army conducted Exercise Yudh Kaushal 3.0 in the high-altitude Kameng region, Arunachal Pradesh. The exercise demonstrated preparedness for next-generation warfare in extreme Himalayan conditions. The exercise marked the operational debut of ASHNI platoons, integrating advanced technology with traditional combat skills. Active participation of the Indian defence industry highlighted indigenous innovation under the vision of self-reliance (Aatmanirbhar Bharat). Yudh Kaushal 3.0 validated combat effectiveness, multi-domain operations, and adoption of emerging technologies.

Notes:
Israel launched its new spy satellite “Ofek-19” into orbit on September 2, 2025. The launch took place from Palmachim Airbase in Israel. Ofek-19 is a Synthetic Aperture Radar (SAR) satellite with advanced surveillance abilities. It successfully entered orbit, transmitted first data, and cleared all initial tests. The satellite can capture high-resolution images day and night in all weather. It can detect objects smaller than 50 cm, improving intelligence accuracy. The launch boosts Israel’s regional intelligence and defense capabilities.

Notes:
During Operation Sindoor, the Indian Army used its indigenous M-Sigma app on SAMBHAV (Secure Army Mobile Bharat Version) smartphones for secure communication. SAMBHAV replaced foreign apps like WhatsApp to prevent external surveillance. The system was launched in 2023 as India’s first fully indigenous secure mobile communication ecosystem. It supports 5G connectivity, multi-tier encryption, and network-agnostic operation for real-time secure communication. M-Sigma allows soldiers to exchange images, videos, and files safely. Nearly 30,000 SAMBHAV-enabled handsets were deployed by early 2024 among army officers. It was also used during military-level talks with China, ensuring secure diplomacy.

Notes:
Union Defence Minister Rajnath Singh flagged off Samudra Pradakshina, an all-women tri-services sailing expedition, from Gateway of India. It is a symbol of Nari Shakti, Aatmanirbhar Bharat, military diplomacy, and global vision. Ten women officers will sail on IASV Triveni, covering 26,000 nautical miles in nine months, crossing the equator twice and sailing around Capes Leeuwin, Horn, and Good Hope. IASV Triveni, a 50-foot yacht built in Puducherry, will stop at ports in Australia, New Zealand, Canada, and South Africa. The voyage highlights India’s progress in women empowerment, maritime adventure, and global recognition.

Notes:
The Indian Army conducted Exercise Siyom Prahar from 8–10 September 2025 in Arunachal Pradesh to validate drone use in tactical operations. The exercise aimed to integrate drones across tactical and operational levels under realistic battlefield conditions. Drones were employed for persistent surveillance, battlefield reconnaissance, target acquisition, and precision strikes. The exercise focused on developing and validating new tactics, techniques, and procedures (TTPs) for future battlefields. It demonstrated integration of drone inputs with conventional firepower, joint targeting, and rapid decision-making in dynamic combat scenarios.
