United States Secretary of Defence Ashton Carter and Union Defence Minister Manohar Parrikar signed the 2015 framework agreement on India-US defence relationship. Parrikar and Carter signed an agreement which builds upon the previous framework and successes to guide the bilateral defence and strategic partnership for the next 10 years. The new framework agreement provides avenues for high level strategic discussions, continued exchanges between armed forces of both countries, and strengthening of defence capabilities. The Framework also recognises the transformative nature of the Defence Technology and Trade Initiative (DTTI). Both India and the United States have finalised two project agreements for joint development of Mobile Electric Hybrid Power Sources and the Next Generation Protective Ensembles. The two also agreed to pursue co-development and co-production projects that will offer tangible opportunities for American defence industries to build defence partnership with the Indian industries including in manufacturing under 'Make in India'. The two nations have agreed to continue their efforts to enhance bilateral cooperation in areas of mutual interest, such as maritime security and knowledge partnership in the field of defence.
