Defence Current Affairs MCQs

Notes:
INS Anjadip commissioned into Indian Navy at Chennai Port on 27 February 2026. It is the fourth ship under Anti-Submarine Warfare Shallow Water Craft project. It is named after Anjadip island near Karwar, it is designed for anti-submarine operations in shallow coastal waters. It has over 80 percent indigenous content, promoting Aatmanirbhar Bharat in defence. The 77 metre, 1400 ton ship has advanced Anti-Submarine Warfare suite and Combat Management System. It follows INS Arnala and INS Androth in this series.

Notes:
The United States conducted a test launch of the Minuteman III missile. Minuteman III is an intercontinental ballistic missile (ICBM) developed by United States. It is part of the US nuclear triad. It is a land-based nuclear missile under the US Air Force Global Strike Command. The missile uses three solid-propellant rocket motors and can reach speeds of about Mach 23 at burnout. It has a range of over 6,000 miles (5,218 nautical miles), enabling long-distance nuclear strike capability.

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 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:
Agray, an anti-submarine warfare shallow water craft, has been delivered to the Indian Navy. It is the fourth of eight ASW Shallow Water Crafts, aimed at strengthening coastal defence capabilities. The vessel is indigenously designed and built by Garden Reach Shipbuilders and Engineers. It is a reincarnation of the earlier INS Agray, a patrol vessel decommissioned in 2017. The ship has been constructed as per standards of the Indian Register of Shipping. It uses waterjet propulsion, making it among the largest Indian naval warships to use this technology. It is equipped with lightweight torpedoes, indigenous rocket launchers, and advanced shallow water SONAR systems for effective submarine detection.

Notes:
INS Dunagiri has been delivered to the Indian Navy as part of ongoing naval modernisation. It is the fifth ship of the Nilgiri-class (Project 17A) stealth frigates. The ship was designed by the Warship Design Bureau and built by Garden Reach Shipbuilding and Engineers. It is a reincarnation of the earlier INS Dunagiri, a Leander-class frigate that previously served in the Indian Navy. The vessel uses Combined Diesel or Gas (CODOG) propulsion, integrating a diesel engine and gas turbine driving controllable pitch propellers (CPP). It is equipped with a modern Integrated Platform Management System (IPMS) for efficient onboard operations.

Notes:
India has inducted its third nuclear-powered ballistic missile submarine, INS Aridhaman, into the Indian Navy, strengthening its strategic deterrence capability. INS Aridhaman is the third indigenously built Submersible Ship Ballistic Nuclear (SSBN) and the second submarine of the Arihant class (Submersible Ship Ballistic Nuclear). It has been developed under the Advanced Technology Vessel project (ATV) at the Ship Building Centre in Visakhapatnam. The submarine has a displacement of about 6,000 tonnes on the surface and 7,000 tonnes when submerged.

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:
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:
Defence Research and Development Organisation has launched the Vikram VT 21 project featuring wheeled and tracked advanced armoured platforms. The platform is designed with enhanced armour protection against projectiles, blasts, and shrapnel. The system includes integrated weapons and advanced surveillance capabilities. It offers modular ballistic and blast protection, improving battlefield survivability. The vehicle is amphibious, enabling operations across water bodies.
