India-US Defence Relations have evolved into one of the most critical pillars of the India-US strategic partnership. The cooperation between the two nations spans defence trade, joint military exercises, technology sharing, and strategic dialogues.

Rooted in mutual democratic values and converging regional interests, this partnership plays a crucial role in maintaining Indo-Pacific stability and enhancing India's defence modernization goals.
Background & Evolution:
The India-US defence relationship has undergone significant transformation since the early 2000s. The 2005 India-US Defence Framework Agreement laid the foundation for long-term strategic cooperation, renewed in 2015 and again in 2020, focusing on co-development and co-production of advanced technologies.
Over the years, the two countries have transitioned from a transactional relationship to a comprehensive global strategic partnership, especially after the signing of key foundational defence agreements.
Major Defence Agreements:
1. LEMOA (Logistics Exchange Memorandum of Agreement) - Signed in 2016, allows mutual use of each other's military bases for logistics and refueling.
2. COMCASA (Communications Compatibility and Security Agreement) - Signed in 2018, enables secure communication between militaries.
3. BECA (Basic Exchange and Cooperation Agreement) - Signed in 2020, facilitates sharing of geospatial intelligence.
4. GSOMIA (General Security of Military Information Agreement) - Signed in 2002, ensures information security and technology protection.
Together, these pacts have enhanced interoperability, intelligence sharing, and defence readiness between the two nations.
Defence Trade & Technology Cooperation:
- The US is now among India's top defence suppliers, providing equipment such as P-8I maritime aircraft, C-17 Globemaster, and Apache & Chinook helicopters.
- The Defence Technology and Trade Initiative (DTTI) aims to promote joint research, co-development, and co-production of defence systems.
