The recently signed Basic Exchange and Cooperation Agreement (BECA) between India and the U.S. symbolises the strengthened defence and security partnership between the two countries and the growing interoperability capabilities between the two militaries. India-U.S. defence and security ties have flourished in the last decade, with increasing focus on defence technology co-development and co-production. The enhanced G2G engagement is also reflected in the commercial sector where American and Indian defence companies have partnered in the aerospace sector to become part of the global supply chain.
