Defence Current Affairs MCQs

Notes:
The Defence Research and Development Organisation (DRDO) successfully completed User Evaluation Trials of the Akash Next Generation (Akash-NG) missile system. Akash-NG is a modern Surface-to-Air Missile (SAM) defence system developed by DRDO and produced by Bharat Dynamics Limited (BDL). It is designed to protect vital areas from enemy air attacks. It is the advanced successor of the Akash missile. The new version is lighter and more advanced. It uses an indigenous Radio Frequency (RF) seeker, dual-pulse solid rocket motor, and fully indigenous radars with Command, Control, and Communication (C2) systems.

Notes:
India recently tested the K-4 missile, an intermediate-range, nuclear-capable submarine-launched ballistic missile (SLBM), from the nuclear-powered submarine INS Arighaat in the Bay of Bengal. K-4 is 12 metres long, weighs 17 tonnes, and uses a two-stage solid-fuel system. It has a range of 3,500 km, a significant upgrade over the older K-15 missile (range 750 km). Each Arihant-class submarine can carry four K-4 missiles. It can carry a payload of up to 2 tonnes, including a nuclear warhead. It is developed indigenously by the Defence Research and Development Organisation (DRDO).

Notes:
China released rare footage of the YJ-20 hypersonic anti-ship missile fired from a Type 055 guided missile destroyer warship. YJ-20, also called Eagle Strike-20, is a hypersonic anti-ship missile developed by China. It was first publicly displayed during China’s Victory Day military parade on 3 September 2025. The missile is designed to attack high-value naval assets like aircraft carriers at long ranges. It has a biconic aerodynamic shape that allows controlled glide after rocket boost. This shape creates shockwaves that protect control surfaces from extreme heat.

Notes:
Pakistan Air Force recently conducted a successful flight test of the indigenously developed Taimoor Weapon System. Taimoor is an air-launched cruise missile developed by Pakistan. It is designed to hit enemy land and sea targets with high precision. It uses subsonic turbojet propulsion, enabling efficient long-range flight. The missile has a strike range of up to 600 kilometres with a conventional warhead. Its stealth features include a box-shaped fuselage, X-type tail, and foldable wings. It flies at very low altitude to evade enemy air and missile defence systems.

Notes:
The Chinese People’s Liberation Army (PLA) Navy has commissioned an upgraded Type 052D guided missile destroyer named Loudi. The induction reflects China’s rapid naval expansion to narrow the gap with United States naval strength. The warship adopts a new system and operational architecture. It has improved combat capabilities in air defence and sea attack roles. The destroyer also strengthens task force command and coordination abilities. The commissioning highlights China’s focus on modern, network-centric naval warfare.

Notes:
The Boeing E-4B Nightwatch, also called the US military’s “Doomsday Plane,” recently made a rare appearance in Los Angeles, causing panic amid high geopolitical tensions. It is the most secretive aircraft in the US military and serves as the National Airborne Operations Center. The plane functions as a flying command post to keep the US government operational during extreme scenarios like nuclear war or destruction of ground command centers. Its mission is to ensure government continuity even in “doomsday” situations. The E-4B is a key part of the Nuclear Command, Control, and Communications system (NC3), allowing senior leaders to manage nuclear forces under all conditions.

Notes:
The Indian Army has launched Depot Integration Management Edition, which is a pan-Army digital logistics platform. It provides near real-time visibility of logistic items from units up to Army Headquarters. It is developed jointly by the Indian Army and Bhaskaracharya National Institute for Space Applications and Geo-informatics. The platform standardises digital workflows across all Army depots and units. It equips commanders with integrated dashboards, exception alerts, and predictive stock analytics. It will reduce paperwork by about 70 percent and shorten the logistics cycle by one-third.

Notes:
On the 10th Armed Forces Veterans Day, Defence Minister Shri Rajnath Singh paid tribute to the courage and sacrifices of the Indian Peacekeeping Force (IPKF) in Sri Lanka. Operation Pawan was conducted by the IPKF after the Indo–Sri Lanka Accord on 29 July 1987. The IPKF was deployed in Sri Lanka until March 1990, when it withdrew following a change in the Sri Lankan government’s policy. The operation involved significant bravery and sacrifice by Indian soldiers, now formally recognised and honoured by the government.

Notes:
The Indian Navy’s Sail Training Ship INS Sudarshini will undertake Lokayan 26, a 10-month transoceanic flagship expedition. INS Sudarshini is an indigenously built Sail Training Ship (STS) of the Indian Navy. It was constructed by Goa Shipyard Limited and is based at Kochi, Kerala, under the Southern Naval Command. The ship was commissioned on 27 January 2012. Such ships train sailors to survive independently at sea, handle rough weather, and develop core seamanship skills. INS Sudarshini is a three-masted barque capable of operating under sail or engine power.

Notes:
More animals were showcased during the Republic Day Parade, highlighting the role of the Indian Army’s Remount and Veterinary Corps (RVC). Remount and Veterinary Corps (RVC) is a specialised corps responsible for the breeding, rearing, training and veterinary care of Army animals such as horses, mules and dogs. It ensures operational readiness of animals for combat, logistics, reconnaissance and counter-terrorism operations. The headquarters of the RVC is located in Meerut.
