- In September 2014, bilateral ties were upgraded to a Special Strategic and Global Partnership, alongside the shared vision of a Free and Open Indo-Pacific (FOIP).
Agreements:
- The 2015 Defence Equipment and Technology Cooperation Agreement framework and Agreement on Protection of Classified Military Information created a legal basis for industrial defence cooperation.
- The 2016 Agreement on Transfer of Defence Equipment and Technology created the basis for practical defence-industrial cooperation.
- The Reciprocal Provision of Supplies and Services Agreement (RPSS/ACSA) subsequently strengthened logistical interoperability.
- The Japan–India Joint Working Group on Defence Equipment and Technology Cooperation provides a mechanism for identifying concrete technology projects.
  - The 7th JWG was noted in 2024, demonstrating institutionalisation of defence-industrial cooperation.
Institutional Dialogue:
- The two nations coordinate their defense cooperation through several key high-level channels:
  - 2+2 Ministers’ Dialogue: Anchored by Foreign and Defence Ministers since 2018.
  - Defence Ministerial Dialogue: Convened annually to set strategic priorities.
  - National Security Adviser Dialogue: Focused on top-level strategic coordination.
  - Defence Policy Dialogue: Shapes bilateral defense frameworks.
  - Staff Talks: Facilitates direct military-to-military engagement.
  - Coast Guard Consultations: Enhances maritime security and cooperation.
Military Exercises:
- Cooperation spans all three services through Dharma Guardian (Army), JIMEX (Navy) and Veer Guardian (Air Force).
  - The upcoming Veer Guardian 26 air exercise will mark the first time that Japan Air Self-Defence Force fighter aircraft visit and participate in a joint drill hosted in India.
- Both countries also participated in Malabar, while Japan joined PASSEX (Trilateral naval exercise involving Japan, India and Indonesia), MILAN and participated in India’s Tarang Shakti multilateral air exercise.

- India and Japan are exploring ship-maintenance cooperation in India, potentially improving Japanese naval operational flexibility and bilateral interoperability.
Projects:
- India and Japan are co-developing the UNICORN (Unified Complex Radio Antenna) mast system, marking their first-ever joint defense manufacturing and technology project.
  - It integrates multiple antennas into one system, reducing the antenna footprint and improving ship stealth.
  - Consolidating exposed arrays significantly lowers a warship’s radar cross-section, making it harder for enemy radar to track.
  - Following a 2024 initial implementation memorandum, the formal co-development was highlighted at the 16th India-Japan Annual Summit in New Delhi.
  - India’s Bharat Electronics Limited (BEL) will manufacture the masts domestically in partnership with Japanese firms like NEC Corporation.
  - India becomes the second Asian nation after the Philippines to receive advanced Japanese defense technology.
- The partnership has extended beyond conventional platforms into Unmanned Ground Vehicles (UGVs) and robotics.
  - In 2024, both sides noted successful completion of cooperation in this field, signalling greater emphasis on emerging military technologies.
