Defence Current Affairs MCQs

Notes:
Ukraine successfully tested its first ballistic missile, named Hrim-2, developed by its defense industry. Hrim-2, also known as Grim, Grom, or OTRK Sapsan, is a Ukrainian short-range ballistic missile system. It combines the features of a tactical missile system and a multiple rocket launcher. The export version of Hrim-2 has a range limited to 280 km to comply with international regulations. For Ukraine’s military, the missile’s range is extended to 700 km. The Sapsan system features a 10-wheeled launcher that carries two missiles and can evade modern air defenses, similar to Russia’s Iskander missile.

Notes:
The Indian Navy and South African Navy signed an agreement to enhance naval cooperation, ensuring the safety of the South African Navy’s submarine crew during emergencies. Under this agreement, the Indian Navy will assist by deploying its Deep Submergence Rescue Vehicle (DSRV) when needed. This strengthens the maritime relationship between India and South Africa. The agreement follows a 2023 incident where three South African Navy personnel died off Cape Town’s coast. South Africa, with a few submarines, will benefit from India’s DSRV, which is used for submarine rescues and covert operations.

Notes:
The Agni-4 missile, developed by DRDO, was successfully tested on 6 September 2024 from Odisha’s Integrated Test Range. This was the ninth test of the nuclear-capable intermediate-range ballistic missile (IRBM). The test was conducted by India’s Strategic Forces Command, which oversees all nuclear weapons. Agni-4 can carry nuclear weapons and will be controlled by the Strategic Forces Command. Development of Agni-4 began in 2007 to strengthen India’s nuclear deterrence against China and Pakistan. The first test in 2010 failed, but the first successful user trial occurred in 2014.

Notes:
The United Kingdom has allowed Ukraine to use Storm Shadow cruise missiles against Russian targets. Storm Shadow is a long-range, air-launched cruise missile with low observability. It was jointly developed by the UK and France, known as SCALP-EG in France. The missile is designed to hit high-value stationary targets like airbases, radar stations, communications hubs, and ports. It is used by the air forces of countries including Egypt, India, Italy, Greece, Saudi Arabia, Qatar, and the UAE.

Notes:
Russia and China have launched joint naval exercises, “Ocean-24,” in the Sea of Japan, highlighting their growing military cooperation. The Sea of Japan is a marginal sea in the western Pacific, bordered by Russia, North Korea, South Korea, and Japan. It connects to the East China Sea, Okhotsk Sea, Inland Sea of Japan, and the Pacific Ocean through various straits. The deepest point of the Sea of Japan is the Dohoku Seamount, an underwater volcano. These exercises signal significant geopolitical movements in the region.

Notes:
The Indian Army inducted 100 robotic Multi-Utility Legged Equipment (MULE) for combat areas, especially in high altitudes. MULEs enhance combat and surveillance missions with thermal cameras and radars for reconnaissance in tough terrains. These robots operate in extreme temperatures (-40 to +55°C), carry a 15kg payload, and can climb stairs and hills. They are durable, agile, and equipped with electro-optics and infrared tech for object recognition, even moving through rivers. MULEs improve surveillance and supply delivery, reducing reliance on animal transport by 50-60% by 2030.
China also uses robotics, hinting at a new military technology race.

Notes:
The Third 25T Bollard Pull Tug, named Ashva, was launched on October 3, 2024, in Kolkata. Ashva is part of the Government of India’s “Make in India” initiative. It was built following the Indian Register of Shipping (IRS) classification rules.
The tug will boost the Indian Navy’s operational capabilities, aiding in critical tasks and enhancing maritime support infrastructure.

Notes:
Iran recently launched over 180 ballistic missiles, including the hypersonic Fattah-2, targeting Israel’s air defenses. Fattah-2 is a new version of Iran’s first domestically made hypersonic ballistic missile, Fattah, which means conqueror in Farsi. It features a hypersonic glide vehicle (HGV) warhead that can maneuver and glide at hypersonic speed. The missile uses a liquid-fuel rocket propellant, allowing its engine to adjust thrust force.

Notes:
India hosts the joint naval exercise of Quad nations from October 8 to 18 in Visakhapatnam. The exercise, named Malabar 2024, includes sea and harbor phases focusing on cooperation in the Indo-Pacific region. It features various Indian naval platforms, such as guided missile destroyers, submarines, and fighter aircraft. The Malabar exercise started in 1992 as a US-India drill and evolved into a multilateral event to enhance interoperability and address maritime challenges. Recent Quad meetings emphasized maritime security cooperation and announced joint coast guard operations and a new regional Maritime Initiative for Training (MAITRI).

Notes:
Army Chief General Upendra Dwivedi unveiled ‘Agniastra,’ a multi-target detonation device, at the Army Commanders Conference in Gangtok. It improves room interventions and bunker destruction, aiding counter-terrorism operations. The device, known as WEDC, enhances safety and reliability over the older Exploder Dynamo Capacitor, which had a limited range of 400 meters. The new microprocessor-based detonation system, developed by Major Rajprasad, operates in both wired and wireless modes with a range of 2.5 km. It allows selective and simultaneous firing of multiple targets, making it highly effective for safe demolition operations. This innovation significantly enhances counter-terrorism efforts and IED destruction, ensuring better safety for troops during critical missions.
