India-South Korea Defence Cooperation Expands with K9 Vajra-T Howitzer Programme

By Published

India and South Korea have strengthened their defence cooperation through the K9 Vajra-T self-propelled howitzer programme, an Indian adaptation of South Korea's K9 Thunder 155 mm artillery gun. Manufactured in India at Larsen & Toubro's facility in Hazira, Gujarat, this project emphasizes technology transfer and indigenous production, achieving 50-60% local components. The first contract for 100 guns was signed in 2017 (₹4,500 crore), followed by a second contract in 2024 for another 100 guns (₹7,629 crore), with a potential future order of 300 guns under a ₹23,000 crore modernisation plan. Deployed along northern and western borders including Ladakh, the K9 Vajra-T enhances India's artillery capabilities in high-altitude terrain. Future cooperation aims to include co-development of air defence systems and missiles, demonstrating a deepening strategic partnership.

Background & Context

The K9 Vajra-T programme represents a successful India-South Korea defence partnership focused on indigenous production and technology transfer, aligning with India's Make in India and self-reliance (Aatmanirbhar Bharat) initiatives. India selected the K9 platform after extensive trials in 2015, outperforming other contenders, such as the Russian 2S19 Msta-S. Larsen & Toubro manufactures the howitzers at the Armoured Systems Complex in Hazira, Gujarat. The programme has enhanced India's self-reliant defence manufacturing capabilities and contributed significantly to its artillery modernization. Deployment of the system along India’s critical high-altitude borders demonstrates its operational suitability for challenging terrains.

Why This Matters for Exams / Exam Relevance

This defence collaboration is an illustrative example of India’s contemporary strategic partnerships and defence industrial policy, emphasizing technology transfer and indigenous manufacturing. Key aspects for examination include contract timelines, manufacturing details, defence procurement processes, and the strategic significance of enhanced artillery capabilities along sensitive borders. The cooperation also highlights evolving bilateral ties and future prospects for missile and air defence co-development, relevant for questions on international defence diplomacy and capability development.
