Defence Current Affairs MCQs

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 Ministry of Defence signed contracts worth Rs 5,083 crore for defence acquisitions. Procurement includes six Advanced Light Helicopters (ALH) Mk-III in Maritime Role for the Indian Coast Guard. Contracts also cover Surface-to-Air Vertical Launch (SAM) Shtil missiles for the Indian Navy. Shtil missile is a medium-range, ship-based, vertical-launch surface-to-air missile system developed by Russia. It primarily uses the 9M317ME semi-active radar homing (SARH) missile.

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:
Recently, Israel reportedly used the Blue Sparrow missile in a strike in Tehran, targeting Ali Khamenei, the Supreme Leader of Iran. The Blue Sparrow missile is part of an air-launched ballistic missile family that also includes the Black Sparrow missile and Silver Sparrow missile. It is developed by Rafael Advanced Defense Systems, an Israeli defence technology company. The missiles were originally designed as target missiles for testing the Arrow missile defence system of Israel. Later, the Blue Sparrow was modified into an offensive air-to-surface missile. It is about 6.5 metres long and weighs around 1.9 tonnes. The missile is usually launched from fighter aircraft such as F-15 jets, which boost it to high altitude.

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:
Sheshnaag-150 is a long-range swarm attack drone being developed in India for deep-strike military missions. It is being developed by NewSpace Research and Technologies (NRT), which focuses on Artificial Intelligence (AI)-based unmanned systems and swarm robotics. It is a collaborative swarm drone, meaning multiple drones can coordinate autonomously to carry out saturation attacks on targets. The drone weighs around 150 kg and can carry 25–40 kg payload, including explosive warheads capable of damaging infrastructure or military vehicles.

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 NATO is deploying the U.S. Patriot Missile Defence System to the southern province of Adana to strengthen regional air defence capabilities. PATRIOT stands for Phased Array Tracking Radar to Intercept on Target. It is a ground-based, mobile missile defence system developed by the United States. The system is designed to detect, track, and intercept aerial threats with high precision.

Notes:
India is set to receive the remaining two units of the S-400 Triumf from Russia in 2026, completing the delivery under the deal. The system was procured under a $5.43 billion agreement signed in 2018 for five squadrons, out of which three are already inducted into the Indian Air Force. The S-400 is a modern long-range surface-to-air missile (MLR SAM) system developed by Russia. It can track and destroy multiple aerial targets at once within a range of up to 600 kilometres. The S-400 provides a powerful multi-layered air defence shield against threats like fighter jets, drones, cruise missiles, ballistic missiles, and stealth aircraft.

Notes:
Rajnath Singh laid the foundation of the Large Cavitation Tunnel (LCT) at Naval Science and Technological Laboratory (NSTL) in Visakhapatnam. NSTL is a premier lab under the Defence Research and Development Organisation (DRDO). The Large Cavitation Tunnel (LCT) is a strategic facility for advanced hydrodynamic research and testing of naval systems. It will enable indigenous design, development, and testing of ships, submarines, and propulsion systems. It supports stealth, noise reduction, and next-generation underwater technologies. The facility allows both closed-loop (submarine) and free-surface (surface ship) simulations.
