Defence Current Affairs MCQs

Notes:
The Indian Navy is commissioning three indigenously built platforms in Kolkata: INS Dunagiri, INS Sanshodhak, and INS Agray. These platforms reflect India’s focus on Aatmanirbhar Bharat in defence production. INS Dunagiri is the fifth Project 17A stealth frigate, designed by the Warship Design Bureau (WDB) and built at Garden Reach Shipbuilders & Engineers (GRSE). INS Sanshodhak is the fourth Survey Vessel (Large) used for hydrographic, oceanographic, and geophysical surveys. INS Agray is the fourth Arnala-class Anti-Submarine Warfare Shallow Water Craft, designed for littoral warfare and underwater threat detection.

Notes:
Russia’s Burevestnik missile recently drew attention after research suggested that its flight may leave a trail of radioactive material due to its nuclear-powered propulsion system. Burevestnik, meaning “Storm Petrel”, is a ground-launched, low-flying, nuclear-powered and nuclear-armed cruise missile developed by Russia. It is regarded as the world’s first nuclear-powered cruise missile. The missile was among the six strategic weapons unveiled by Russian President Vladimir Putin in 2018. NATO designates the missile as SSC-X-9 Skyfall.

Notes:
An Indian Navy Drishti-10 Starliner UAV crashed near Dharampur village in Porbandar district, Gujarat, during a routine training sortie, following which a Board of Inquiry (BoI) was ordered. Drishti-10 Starliner is an indigenous Unmanned Aerial Vehicle (UAV). It is a variant of Israel’s Elbit Systems’ Hermes 900 platform and is manufactured by Adani Defence and Aerospace at its Hyderabad facility under a technology transfer agreement. The UAV is designed for Intelligence, Surveillance, and Reconnaissance (ISR) missions. It plays an important role in strengthening India’s maritime and border security.

Notes:
India has developed its first indigenous Expendable Turbo Jet Engine in the 350 kg thrust class. The engine was developed by DRDO’s Gas Turbine Research Establishment (GTRE). It was successfully realised and delivered to GTRE by Azad Engineering. The development marks a major milestone in India’s indigenous jet engine technology and defence manufacturing capabilities.

Notes:
The Indian Air Force (IAF) conducted Exercise ROTOR CLAP III at the Pokhran Field Firing Range, Jaisalmer (Rajasthan). The week-long exercise focused on the theme “Counter-UAS (Counter Unmanned Aerial Systems).” It aimed to strengthen the operational capabilities of the IAF’s helicopter fleet against emerging drone threats. Nearly all major IAF helicopter platforms participated in the exercise. The exercise validated tactics, techniques, procedures (TTPs), mission planning, interoperability, and rapid response.

Notes:
Australia is set to become the first international buyer of the US-made AIM-260 Joint Advanced Tactical Missile (JATM). AIM-260 JATM is an American beyond-visual-range air-to-air missile developed by Lockheed Martin for the U.S. Air Force and U.S. Navy. It is designed to have a longer range than the AIM-120 AMRAAM and counter advanced threats such as China’s PL-15. The missile features a wingless supersonic design and is approximately 4 metres long. Its estimated range is more than 180–200 km, making it an important component of the U.S. long-range air-combat capability.

Notes:
The United States Army has temporarily halted AH-64 Apache training flights following a crash near Fort Hood, Texas, that killed two soldiers. The AH-64 Apache is a two-seat attack helicopter, with the pilot seated at the rear and the co-pilot/gunner in the front. It is made by Boeing in the United States and used by many countries, including India, Egypt, Greece, and Japan. It can fly up to 300 kilometres per hour and has a range of 500 kilometres. It has advanced systems for communication, navigation, sensors, and weapons.

Notes:
INS Imphal (D68) marked India’s 80th Independence Day with a port call at Sultan Qaboos Port, Muscat, Oman. More than 200 Indian school students in Oman visited the indigenously built destroyer. INS Imphal is a stealth guided-missile destroyer of the Indian Navy and was commissioned on 26 December 2023. It was built by Mazagon Dock Shipbuilders Limited (MDL) and designed by the Warship Design Bureau of the Indian Navy. It is the third ship of the Visakhapatnam class (Project 15B). INS Imphal is the first Indian naval warship with dedicated modular accommodation and facilities for women officers and sailors.

Notes:
The Indian Army has raised its first Baaz Battalion equipped with sophisticated drones under the 11 Corps (Vajra Corps). The battalion has been operationalised in Jalandhar, Punjab, with a focus on the sensitive western border region. Named after the hawk (Baaz), the unit is intended to strengthen the Army’s Intelligence, Surveillance and Reconnaissance (ISR) capabilities. The drone unit will act as the Army’s “eyes in the sky”, providing real-time aerial surveillance and improving operational response. The initiative is part of the Indian Army’s broader military modernisation and transformation, drawing on recent operational experiences, including Operation Sindoor.

Notes:
DRDO successfully tested the indigenous Military Combat Parachute System (MCPS) at 22,000 feet in Nyoma-Mudh, Ladakh. The trial was conducted at around −15°C, demonstrating the system’s suitability for high-altitude and extreme cold conditions. The parachute was deployed at 20,000 feet, with the test jumpers landing safely at 13,700 feet. The trial also validated indigenous subsystems such as the para computer, specialised oxygen systems and specialised jumpsuits. The test strengthens India’s indigenous defence capabilities and operational readiness in high-altitude environments.
