Quick Revision: Japan’s exploration of India-based training for long-range missiles and attack drones reflects the strategic imperative of Indo-Pacific defence cooperation, leveraging India’s indigenous capabilities and shared security interests.

Why is this in the news?

Japan’s Ground Self-Defense Force (GSDF) has dispatched personnel to India to coordinate defence-related training for long-range surface-to-ship missiles (SSM) and small attack drones, signalling a deepening strategic partnership between Tokyo and New Delhi. This initiative underscores the growing emphasis on operationalising Indo-Pacific defence cooperation amid evolving regional security dynamics, including the need for extended-range strike capabilities and joint military training environments.

Background

• The Japan-India defence partnership has evolved significantly since the signing of the 2008 Joint Declaration on Security Cooperation and the 2019 Acquisition and Cross-Servicing Agreement (ACSA), which facilitates mutual logistical support during joint exercises and operations.
• India and Japan are key stakeholders in the Indo-Pacific region, with shared concerns over maritime security, freedom of navigation, and the rise of China’s military assertiveness in the South China Sea and Indian Ocean.
• Japan’s National Security Strategy (2022) and National Defence Strategy (2022) prioritise strengthening defence ties with like-minded partners, including India, to counterbalance regional security challenges.
• India’s indigenous defence capabilities, particularly in missile technology and wargaming, have attracted international interest, as demonstrated by Japan’s delegation visits to DRDO, CLAWS, and WARDEC in October 2026.
• The Indo-Pacific region’s strategic significance has led to increased defence cooperation among Quad members (India, Japan, Australia, and the United States) and other regional partners.
• Japan’s long-range missile systems, such as the Type 12 SSM, require extensive training environments to validate operational readiness, prompting exploration of overseas training facilities.

What is Japan-India Defence Cooperation on Long-Range Missiles and Drones?

• Japan’s Ground Self-Defense Force (GSDF) is exploring training options for its long-range surface-to-ship missiles (SSM), including the Type 12 SSM, which has an operational range of approximately 1,000 km, necessitating specialised training environments.
• The GSDF is considering both domestic and international training facilities to address the challenges posed by extended-range missile operations, including India as a potential host for joint exercises.
• Small attack drones, such as the GSDF’s ongoing procurement of loitering munitions, also require rigorous training to ensure precision strike capabilities, further motivating defence exchanges with India.
• India’s Defence Research and Development Organisation (DRDO) has developed indigenous long-range missiles, including the BrahMos supersonic cruise missile and the Agni series of ballistic missiles, providing a complementary technological base for joint training.
• The Centre for Land Warfare Studies (CLAWS) and the Wargame Research and Development Centre (WARDEC) in India are institutions that facilitate military training, strategic studies, and wargaming, attracting international delegations for knowledge exchange.
• Japan’s delegation visit to India in October 2026 included interactions with the Indian Army and DRDO, aiming to deepen professional military ties and enhance mutual understanding of defence capabilities.
• The Japan-India defence partnership is part of a broader Indo-Pacific security architecture that emphasises multilateral cooperation, interoperability, and shared strategic interests.
• Defence cooperation between Japan and India is governed by agreements such as the 2008 Joint Declaration on Security Cooperation and the 2019 Acquisition and Cross-Servicing Agreement (ACSA), which enable logistical support and joint exercises.
