Defence Current Affairs MCQs

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:
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 Islamic Revolutionary Guard Corps Navy tested the Sayyad-3G air defense missile. Sayyad-3G is a naval surface-to-air missile developed by Iran. It is derived from the land-based Sayyad-3 missile and modified for maritime use. It provides medium-range air defense to warships and naval vessels. It is launched through a Vertical Launch System, giving 360-degree coverage. It can quickly respond to aerial threats. It can intercept warplanes, maritime patrol aircraft, and high-altitude Unmanned Aerial Vehicles (UAVs).

Notes:
Recently, the President of India undertook a sortie in the indigenous Light Combat Helicopter (LCH) Prachand at Air Force Station Jaisalmer, Rajasthan. It is an indigenously developed Light Combat Helicopter made by Hindustan Aeronautics Limited. It is the only attack helicopter in the world capable of landing and taking off at 5,000 metres (16,400 feet). It has advanced stealth features, armoured protection and night attack capability. It has crash-resistant landing gear for better survivability. It reduces radar and Infrared (IR) signature and has a countermeasure dispensing system against enemy missiles.

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:
Kheybar Shekan Missile is a long-range solid-fuel ballistic missile developed by the Islamic Revolutionary Guard Corps (IRGC) of Iran. Recently, Iran claimed that IRGC used Kheybar Shekan missiles to target the office of Israeli Prime Minister Benjamin Netanyahu and an Israeli Air Force command centre. The missile belongs to the Khorramshahr missile family and represents an advanced generation of Iran’s missile system. It has an approximate range of about 1,450 kilometres, enabling strikes across much of the Middle East region. It uses solid fuel technology, which allows faster launch preparation, easier storage, and improved mobility.

Notes:
Defence Research and Development Organisation and the Indian Navy successfully conducted four in-flight release trials of the ADC-150 (Air Droppable Container-150) from the Boeing P-8I Poseidon near Goa. ADC-150 is an indigenously developed container capable of carrying 150 kg payload for aerial delivery. The parachute system was developed by Aerial Delivery Research and Development Establishment. Instrumentation support came from Defence Research and Development Laboratory. The system enables rapid aerial delivery of equipment, supplies and medical aid to naval ships operating in open sea or emergencies.

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.
