Defence Current Affairs MCQs

Notes:
In January 2026, the Indian Army created a modern warfare force named Bhairav to strengthen combat capabilities. Bhairav battalions are designed for high-speed offensive and special operations at tactical and operational levels. Around 15 Bhairav battalions have been raised, with plans to expand to 25. These units bridge the gap between Para Special Forces and regular Infantry. Bhairav units are technology-driven and capable of independent multi-domain operations.

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:

Notes:
India will debut its Long-Range Anti-Ship Hypersonic Glide Missile (LR-AShM) at the 77th Republic Day parade, marking entry into the hypersonic anti-ship weapons club. LR-AShM is an indigenous missile developed by the Defence Research and Development Organisation (DRDO) for the Indian Navy. It is designed to destroy high-value naval targets like aircraft carrier battle groups at very long ranges. The missile enhances maritime deterrence in the Indian Ocean Region (IOR) and strengthens Anti-Access/Area Denial (A2/AD) capability.

Notes:
Defence Research and Development Organisation (DRDO) successfully demonstrated Solid Fuel Ducted Ramjet (SFDR) technology on February 3, 2026, from Integrated Test Range (ITR), Chandipur, Odisha. The demonstration positions India among elite nations with SFDR capability for long-range air-to-air missiles, providing a tactical advantage. The missile was initially propelled by a ground booster to reach the desired Mach number.

Notes:
Indian Air Force (IAF) is conducting joint in-situ air exercise with Royal Thai Air Force (RTAF) to improve coordination and interoperability. Indian Air Force (IAF) is deploying Su-30MKI, Airborne Warning and Control System (AWACS), Airborne Early Warning and Control (AEW&C) and IL-78 mid-air refuelling aircraft. Royal Thai Air Force (RTAF) is participating with Gripen fighter aircraft. Exercise strengthens Indo-Thai defence cooperation and regional security synergy.

Notes:

Iran recently released dramatic footage of its Khorramshahr‑4 ballistic missile amid rising tensions with the United States of America (USA). The Khorramshahr‑4, also called the Kheibar missile, is a medium-range ballistic missile (MRBM). It is developed by the Iranian state-owned defence company Aerospace Industries Organization (AIO). The missile uses liquid fuel for propulsion. It has an operational range of around 2,000 kilometers. The missile travels faster than the speed of sound. It is considered one of Iran’s most powerful medium-range missiles.

Notes:
Indian Coast Guard inaugurated India’s first Waterjet Production and Testing Facility of Marine Jet Power in Goa on 13 February 2026. The facility will manufacture, test and maintain advanced waterjet propulsion systems for high-speed vessels. It supports Aatmanirbhar Bharat by reducing dependence on foreign technology. India became the third country after the United States and South Korea to host such a facility. Indian Coast Guard operates over 100 Marine Jet Power systems and 42 more are under construction. It will support maintenance, regional exports, Micro, Small and Medium Enterprises, skilled jobs and defence indigenisation.
