Defence Current Affairs MCQs

Notes:
Yildirimhan Missile is a prototype intercontinental ballistic missile (ICBM) unveiled by Turkey to strengthen defence self-reliance and expand its strategic military capabilities. The missile is capable of targeting regions across Europe, Africa, and Asia if launched from Turkey. Yildirimhan can reportedly travel at speeds up to Mach 25, which is nearly 25 times the speed of sound and falls under hypersonic speed range. It uses four rocket propulsion engines and is powered by liquid nitrogen tetroxide fuel, which improves range and payload capacity.

Notes:
INS Sagardhwani recently visited Cam Ranh, Vietnam, strengthening India-Vietnam scientific cooperation. It is an oceanographic research vessel commissioned in July 1994. The name “Sagardhwani” means “sound or voice of the sea.” The vessel was designed by Naval Physical and Oceanographic Laboratory (NPOL), Kochi, and built by Garden Reach Shipbuilders & Engineers (GRSE). It is equipped with advanced scientific laboratories and equipment for oceanographic research. INS Sagardhwani contributes to marine acoustics, naval oceanography, and collaborates with Defence Research and Development Organisation laboratories under the Sagar Maitri initiative.

Notes:
The Girder Laying Ceremony for the 4th, 5th, and 6th Air Cushion Vehicle of the Indian Coast Guard was held at the Rassaim Yard of Chowgule Shipyard in Goa on 11 May 2026. These Air Cushion Vehicles are being manufactured under the Aatmanirbhar Bharat initiative with around 50% indigenous content. The contract for six indigenously designed and built Air Cushion Vehicles was signed with Chowgule & Company Private Limited in October 2024. The vehicles will be used for coastal patrolling, reconnaissance, interception, interdiction, and search-and-rescue operations.

Notes:
India successfully conducted the second flight trial of the Divyastra Missile from Dr. APJ Abdul Kalam Island, Odisha. Divyastra is an advanced Agni missile equipped with Multiple Independently Targeted Re-entry Vehicle (MIRV) technology. It was developed by India’s Defence Research and Development Organisation (DRDO). MIRV technology enables a single missile to carry multiple nuclear warheads that can strike different targets independently. MIRV technology was first developed by the United States in the 1960s.

Notes:
Sanghmitra was launched at Garden Reach Shipbuilders and Engineers in Kolkata under the Indian Navy’s indigenous shipbuilding programme. The vessel is part of the Indian Navy’s project to build 11 Next Generation Offshore Patrol Vessels (NGOPVs) at GRSE and Goa Shipyard Limited. These indigenously built ships will support maritime surveillance, coastal defence, anti-piracy patrols, search and rescue, and humanitarian assistance and disaster relief operations. The vessel is named after Sanghamitra, reflecting India’s cultural heritage.

Notes:
Defence Minister Rajnath Singh inaugurated an artillery shell manufacturing plant at Savli Vihir Industrial Estate in Shirdi, Maharashtra. The project has been established by Nibe Limited. The facility will manufacture 155 mm artillery shells with an annual production capacity of five lakh shells. The entire production technology and raw materials used in the plant are indigenous, supporting the Make in India initiative.

Notes:
Defence Research and Development Organisation and the Indian Air Force successfully conducted flight-tests of the RudraM-II air-to-surface missile from an airborne platform. The tests were conducted under extreme release conditions and successfully validated the performance of all major subsystems. The missile accurately hit a predefined target, and all objectives were confirmed through data collected by the Integrated Test Range.The weapon was specifically designed and developed by the Research Centre Imarat (RCI), a nodal DRDO laboratory based in Hyderabad.

Notes:
The Defence Minister recently reviewed the progress of major HAL projects, including delays in the delivery of the Light Combat Aircraft (LCA) Tejas Mk1A. The Ministry of Defence has signed a contract with Hindustan Aeronautics Limited for the procurement of 97 Tejas Mk1A aircraft for the Indian Air Force (IAF). Tejas Mk1A is developed by HAL. It is regarded as one of the world’s lightest fighter aircraft in its class. The aircraft is capable of offensive air support, air combat, and ground attack missions.

Notes:
The Defence Research and Development Organisation (DRDO) has achieved a major milestone by granting Final Operational Clearance (FOC) to the indigenous Netra Airborne Early Warning and Control (AEW&C) system for induction into the Indian Air Force. The system was developed jointly by DRDO, Indian Air Force (IAF), and industry partners to enhance airborne surveillance, situational awareness, and battle management capabilities. The Netra AEW&C had earlier received Initial Operational Clearance (IOC) in 2017, marking its gradual progression to full operational readiness. The system reflects India’s progress in indigenous defence technology and self-reliance under Atmanirbhar Bharat.

Notes:
Prime Minister Narendra Modi handed over the indigenously built Fast Patrol Vessel (FPV) PS LESPWAR and other assistance to Seychelles during his State Visit. The FPV was built by Goa Shipyard Limited. The vessel can achieve speeds of over 30 knots. It strengthens Seychelles’ maritime surveillance, anti-piracy operations, and patrolling of its Exclusive Economic Zone (EEZ).
