Defence Current Affairs 03 September 2025

Exercise Maitree – XIV

• The 14th edition of the India – Thailand joint military Exercise MAITREE-XIV commenced with a grand opening ceremony at Joint Training Node (JTN), Umroi, Meghalaya.
• The exercise is being conducted from 1st to 14th September 2025.
• The bilateral exercise is part of the ongoing military-to-military exchange programme between the two countries and aims to enhance cooperation, interoperability and mutual understanding between the Indian Army and Royal Thai Army.
• The 13th edition of the exercise was held at Fort Vachiraprakan in Tak Province, Thailand.
• The Indian Army contingent comprising 120 personnel, is being represented by a Battalion of the Madras Regiment. The Royal Thai Army contingent comprising 53 personnel is represented by the 1st Infantry Battalion, 14th Infantry Brigade.
• Exercise MAITREE, instituted in 2006, is one of the important joint training exercises between India and Thailand.

Kalam-250 Solid Rocket Motor

• The Kalam-250 solid rocket motor, developed by Skyroot Aerospace, represents a breakthrough in India’s private spaceflight capabilities, standing out as the largest and most advanced propulsion system successfully tested by the private sector in collaboration with ISRO.
• Fired for the first time in March 2024 at the Satish Dhawan Space Centre, Sriharikota, the stage-two motor is designed using cutting-edge high-strength carbon composite materials that provide exceptional structural robustness while keeping mass low—an essential factor for launch efficiency.
• It incorporates a sophisticated Ethylene-Propylene-Diene Terpolymer (EPDM) thermal protection system (TPS), enabling it to endure extreme thermal and mechanical stresses encountered during lift-off and high-velocity atmospheric flight.
• Another standout feature is its advanced thrust vector control system, which integrates a carbon ablative flex nozzle paired with electro-mechanical actuators to deliver precision steering and optimized trajectory management.

What Is Vikram-3201 Chip

• India’s semiconductor journey reached a decisive milestone at SEMICON India 2025, when Union Minister for Electronics and IT, Ashwini Vaishnaw, presented Prime Minister Narendra Modi with the Vikram-3201 — a cutting-edge 32-bit microprocessor designed and developed entirely within India.
• This achievement represents a turning point in India’s pursuit of technological self-reliance, particularly in critical sectors such as space electronics, defence, and high-reliability applications, where trust in foreign technology is both costly and limited.
• It holds the distinction of being the first indigenously developed 32-bit processor qualified for use in the hostile environment of space launch vehicles, where extreme temperature variations, radiation, and high reliability are non-negotiable requirements.
• The chip has been validated for operations under extreme conditions, performing reliably across a temperature range of –55°C to +125°C. Its primary applications lie in navigation, control, and mission management systems of India’s space vehicles, where any computational failure can jeopardize an entire mission.
• The development of Vikram-3201 is rooted in India’s earlier successes. Since 2009, ISRO has relied on the VIKRAM1601, a 16-bit processor, as a fundamental component of its launch vehicle electronics.
• Key advancements include support for 64-bit floating-point arithmetic, enhancing its precision and performance in computation-heavy applications such as trajectory correction, orbital manoeuvre planning, and real-time mission control.

Adani Defence To Join Race For AMCA

• The Advanced Medium Combat Aircraft (AMCA) project represents one of India’s most ambitious defence programs, aimed at developing a cutting-edge fifth-generation multirole stealth fighter jet with indigenous capabilities.
• The project, spearheaded by the Aeronautical Development Agency (ADA) under the Defence Research and Development Organisation (DRDO), seeks to strengthen India’s strategic autonomy by reducing reliance on foreign combat aircraft platforms.
• The AMCA is envisioned as a twin-engine, stealth-capable fighter designed for a wide spectrum of roles, including air dominance missions, ground attack operations, and advanced electronic warfare tasks.
• Adani Defence’s entry into the procurement race marks an important milestone, signalling the growing confidence and capability of India’s private sector defence companies to handle complex, high-technology projects.
