From C-17s to Apaches: India-US defence ties reach a new level as Washington marks 250 years
The relationship between India and the United States has undergone a major shift in defence cooperation, moving from Cold War-era mistrust and sanctions to a partnership that now spans military exercises, intelligence sharing, technology transfers and large-scale arms sales. The latest account of that evolution comes as the United States marks 250 years of independence, with the two countries described as having become close strategic partners in the Indo-Pacific. The development is being framed around a series of agreements and purchases that have expanded interoperability between their armed forces.

According to the supplied material, a turning point came in 1962 during the Sino-Indian War, when Washington supplied India with weapons, transport aircraft and training. The same material says the United States had also offered India $500 million in credit and grants for non-combat defence machinery, although that offer did not materialise. Military ties were later frozen with India and Pakistan after the 1965 war between the two neighbours, underscoring how limited the relationship remained for years.
The current defence partnership is presented as the result of a long and gradual rebuilding process rather than a sudden change. A more structured phase began in 2005, when the two countries signed the New Framework for the US-India Defence Relationship. That 10-year pact set priorities for counterterrorism, humanitarian assistance and disaster relief, and maritime security cooperation.
A similar framework was signed again in 2015 for another 10 years, and the following year the United States designated India as a Major Defence Partner. The supplied material says these steps helped create the basis for deeper military cooperation and a much wider defence relationship. The article also places the India-US partnership within the wider Quad grouping, which includes Japan and Australia.

It says the Quad began with humanitarian relief after the 2004 Indian Ocean tsunami and later evolved into a strategic partnership committed to fostering a free and open Indo-Pacific. That evolution matters because it links bilateral defence ties to a broader regional security architecture. It also shows how the relationship now extends beyond arms purchases into shared strategic goals.
The scale of the transformation is reflected in the range of defence areas now covered, including exercises, intelligence sharing and defence technology. The supplied material says the United States has become one of India's largest defence suppliers and closest military partners over the past two decades. It also points to billions of dollars in arms sales, indicating that the relationship has moved into a more sustained and institutionalised phase.
For both sides, that suggests a level of trust and practical cooperation that would have been difficult to imagine during the Cold War. The background also includes periods of tension that shaped the current trajectory. The freezing of military ties after the 1965 war is presented as a reminder of how political and security disputes once constrained cooperation.
The later framework agreements in 2005 and 2015, by contrast, show a deliberate effort to build predictability into the relationship. The designation of India as a Major Defence Partner in 2016 further signalled Washington's intent to deepen engagement. The supplied material refers to remarks and developments in October 2025 during the 12th ASEAN Defence Ministers' Meeting in Kuala Lumpur, where Defence Minister Rajnath Singh was involved in the broader defence dialogue.

However, the row provided does not include the full details of that event, so its exact relevance cannot be fully established from the available text alone. What is clear is that the defence relationship continues to be discussed in multilateral settings as well as bilaterally. That suggests the partnership is now part of a wider regional diplomatic and security conversation.
