Defence Current Affairs MCQs

Notes:
South Korean and United States air forces have started the Buddy Squadron joint aerial exercise at Osan Air Base in Pyeongtaek. The exercise aims to improve interoperability and integrated tactical skills between the two allies. Buddy Squadron is a battalion-level drill conducted alternately by South Korea and the United States. It focuses on sharing air-to-air combat tactics and integrated training. The exercise involves fourth- and fifth-generation fighter jets. It strengthens joint operational readiness and regional security cooperation.

Notes:
The Ministry of Defence has signed a ₹2,312 crore contract with Hindustan Aeronautics Limited to procure eight Dornier 228 aircraft for the Indian Coast Guard. The programme is expected to generate direct and indirect employment by strengthening HAL’s production ecosystem and supporting MSMEs and ancillary industries. It will create sustained opportunities in maintenance, repair, overhaul, and life-cycle technical support. Dornier 228 is a twin-engine turboprop Short Take-Off and Landing (STOL) utility aircraft for passenger, cargo, and special mission operations. Originally developed by Dornier GmbH (Germany) in the 1980s, it is now license-produced by HAL at its Kanpur facility.

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:
The sail training ship (STS) INS Tarangini arrived in Visakhapatnam for the International Fleet Review (IFR) and MILAN exercise starting February 18. INS Tarangini is the Indian Navy’s first sail training ship. It became the first Indian naval ship to circumnavigate the globe in 2003‑2004. Its primary role is to instill courage, camaraderie, and endurance in officer cadets starting a naval career. The ship provides hands-on training in sailing, setting and furling sails, watch-keeping, and sail manoeuvres.

Notes:
The Indian Army’s Southern Command conducted Exercise Vajra Ghaat at Pokhran Field Firing Range in Jaisalmer district, Rajasthan. The exercise focused on testing the K9 Vajra self-propelled artillery gun system in desert warfare conditions of the Thar Desert. It was spearheaded by the White Tiger Division. The objective is to validate refined Tactics, Techniques and Procedures (TTPs) for better survivability and operational effectiveness. The drill demonstrated swift deployment of heavy artillery in harsh terrain. K9 Vajra carried out high-intensity, precise fire missions.

Notes:
The Integrated Fire and Manoeuvre Exercise Agni Varsha was conducted at Pokhran Field Firing Range, Jaisalmer, Rajasthan, by the Southern Command of the Indian Army. The exercise highlighted combat effectiveness of mechanised forces operating across multiple domains. Foreign defence journalists from 25 countries witnessed the exercise, observing speed, accuracy, and synchronisation of Combined Arms formations in the Thar Desert. Agni Varsha incorporated modern battlefield technologies: unmanned aerial systems, counter-drone measures, precision strike rockets, artillery platforms, and networked surveillance assets.

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 has raised concerns about the capabilities of Iran’s Shahed attack drones. Shahed drones are low-cost, one-way-attack unmanned aerial vehicles developed by Iran. These drones are also called “kamikaze” or “suicide” drones as they explode on impact with their targets. The most widely used variants of Shahed drones are Shahed-131 and Shahed-136. Their low cost, low-altitude flight profile, and self-sacrificial nature have earned them the label “the poor man’s cruise missile.”

Notes:
The Precision Strike Missile (PrSM) was recently used by the United States for the first time in operations by United States Central Command during the conflict with Iran. It is a surface-to-surface guided ballistic missile designed to strike long-distance targets with very high precision. The missile is developed mainly for the United States Army by Lockheed Martin, a major US aerospace and defence company. It has an open system architecture and modular design, allowing upgrades and integration with new technologies.

Notes:
Recently, Iran reportedly destroyed a key THAAD radar system used by the United States in the Middle East, affecting part of its missile-defence network. THAAD (Terminal High Altitude Area Defense) is an advanced ballistic missile defence system developed by the United States to counter missile threats. It is designed to intercept short, medium and limited intermediate-range ballistic missiles during the terminal phase, which is the final stage of their flight. The system can destroy incoming missiles both inside and outside Earth’s atmosphere, providing a high-altitude defence layer.
