Defence Current Affairs MCQs

Notes:
The Malwan has been delivered to the Indian Navy as part of efforts to strengthen coastal defence capabilities. It is the second of eight Anti-Submarine Warfare Shallow Water Crafts (ASW SWC) being built by Cochin Shipyard Limited at Kochi, and is indigenously designed and constructed. The vessel is named after Malwan and carries forward the legacy of the former INS Malwan, a naval minesweeper that served until 2003. It is designed for Anti-Submarine Warfare (ASW), coastal surveillance, Low Intensity Maritime Operations (LIMO), and mine warfare.

Notes:
Indian Air Force is preparing to induct unmanned stealth fighters under the Remotely Piloted Strike Aircraft (RPSA) programme. RPSA aims to develop Unmanned Combat Aerial Vehicle (UCAV) named Ghatak UCAV. Unmanned Combat Aerial Vehicles carry missiles and bombs for autonomous strike and combat operations. Ghatak features a stealthy flying-wing design for low radar detection. It can conduct deep-strike missions in heavily defended airspace without risking pilots.

Notes:
Russia has approved the sale of the R-37M (Russian long-range air-to-air missile), also known as AA-13 Axehead (North Atlantic Treaty Organization reporting name), to India to enhance its air combat capability. The missile is designed for BVR (Beyond Visual Range) combat, allowing it to strike targets at very long distances without direct visual contact. It is developed to destroy enemy fighter jets, drones, and other aerial threats effectively. The missile is nicknamed an “AWACS (Airborne Warning and Control System) Killer” because it can target high-value aircraft like radar planes, refuelling tankers, and jamming systems.

Notes:
The Ministry of Home Affairs received an indigenous satellite imaging system Prajna, developed by Defence Research and Development Organisation through CAIR (Centre for Artificial Intelligence and Robotics), to improve real-time decision-making for security agencies. The AI-enabled Prajna system is designed to monitor sensitive regions and support counter-terrorism operations, thereby strengthening internal security. DRDO and the Indian Navy successfully conducted in-flight trials of ADC-150 (Air Droppable Container with 150 kg capacity) from the P-8I aircraft off the Goa coast.

Notes:
Defence Research and Development Organisation unveiled Advanced Armoured Platforms (tracked & wheeled) on April 25, 2026, at Ahilyanagar, Maharashtra. These platforms were developed by Vehicles Research and Development Establishment to meet evolving operational needs of Indian defence forces. They feature an indigenously developed 30 mm crewless turret with a 7.62 mm PKT gun and Anti-Tank Guided Missile capability.

Notes:
INS Kalpeni is a fast attack craft of the Indian Navy and recently visited Gan, strengthening India–Maldives maritime cooperation. It belongs to the Car Nicobar class Waterjet Fast Attack Craft built by Garden Reach Shipbuilders and Engineers. It was commissioned on 14 October 2010. The ship is named after Kalpeni Island of Lakshadweep. It is based at Kochi under the Southern Naval Command. Its roles include coastal surveillance, anti-smuggling, boarding operations, and search and rescue.

Notes:
INS Mahendragiri is the sixth Nilgiri-class (Project 17A) stealth frigate delivered to the Indian Navy on 30 April 2026. It was constructed at Mazagon Dock Shipbuilders Limited in Mumbai, marking progress in indigenous warship building. Project 17A frigates are advanced multi-mission warships with improved stealth, survivability, and combat capabilities. The ship was designed by the Warship Design Bureau using an integrated construction approach. It uses Combined Diesel or Gas (CODOG) propulsion along with Controllable Pitch Propellers (CPP).

Notes:
The Indian Army contingent has reached Cambodia for the second edition of the India–Cambodia joint military exercise CINBAX-II 2026. The exercise is held at Techo Sen Phnom Thom Mreas Training Centre in Kampong Speu Province, Cambodia from May 4 to 17, 2026. Around 120 Indian personnel, mainly from the Maratha Light Infantry Regiment, are participating. The Cambodian side is represented by about 160 personnel from the Royal Cambodian Army. The exercise is conducted under the framework of Chapter VII of the United Nations mandate. It focuses on counter-terrorism operations in sub-conventional and semi-urban environments.

Notes:
INS Sagardhwani arrived in Vietnam as part of efforts to strengthen scientific and maritime cooperation. The vessel was flagged off for the 5th edition of the Sagar Maitri initiative. Sagar Maitri is a flagship collaborative programme of the Indian Navy and the Defence Research and Development Organisation aligned with the MAHASAGAR vision. MAHASAGAR stands for Mutual and Holistic Advancement for Security and Growth Across Regions. INS Sagardhwani is a specialised oceanographic research vessel commissioned in July 1994, designed by Naval Physical and Oceanographic Laboratory (NPOL) of DRDO and built by Garden Reach Shipbuilders & Engineers

Notes:
Suryastra Rocket System was recently successfully tested at Chandipur, marking a major milestone in India’s indigenous defence technology. The system was developed by NIBE Limited in collaboration with Elbit Systems. Suryastra is India’s first indigenous universal multi-calibre rocket launcher system designed for precision strikes on enemy command centres, radar sites, and logistics hubs. It is mounted on a mobile 6×6 Tatra truck and can engage multiple targets simultaneously at different ranges. The system uses interchangeable modular pods capable of firing different types of munitions.
