Strategic Shifts in India’s Military Capabilities
Recent advancements in missile technology, extended ranges, and frequent testing indicate that India is moving beyond its declared nuclear posture. The development of long-range ballistic missiles, intercontinental ballistic missiles (ICBMs), and submarine-launched systems reflects a shift away from minimum deterrence toward greater strategic dominance and deliberate ambiguity in its nuclear policy. While the official doctrine still emphasizes No First Use (NFU) and Credible Minimum Deterrence (CMD), the scale and sophistication of India’s strategic weapons development suggest a shift toward a more flexible and more aggressive nuclear stance.
India has emerged as one of the world’s largest arms importers, accounting for 8.3 percent of total global arms imports between 2020 and 2024. This places it as the second-largest importer behind Ukraine. A significant portion of these weapons comes from the United States and Russia. The U.S. sees India as a key partner in countering China and advancing its Indo-Pacific strategy. This strategic cooperation between the two countries challenges the regional power dynamics in South Asia. The arms India imports from the U.S. heighten Pakistan’s security concerns and hold strategic relevance for China.
The U.S. has provided India with exceptional treatment through strategic titles, advanced arms sales, and special agreements. This not only fuels India’s global ambitions but also generates insecurity at both regional and global levels. To position India as a strategic counterweight to China, the West, particularly the U.S., has actively supported India’s military build-up. As part of the U.S.-India strategic partnership, India received a waiver from the Nuclear Suppliers Group (NSG) in 2008. This exemption enabled New Delhi to sign nuclear agreements with several countries without being required to join the Nuclear Non-Proliferation Treaty (NPT) or formally become a member of the NSG. Consequently, India has vertically proliferated after signing these agreements without shouldering any responsibilities.
India was designated as a “Major US Defence Partner.” Likewise, Strategic Trade Authorization Tier-1 status granted India access to a broad spectrum of American and other Western military and dual-use technologies. Other strategic export control cartels were also opened for India. Initiatives such as the Defence Technology and Trade Initiative (DTTI), Logistics Exchange Memorandum of Agreement (LEMOA), Communications Compatibility and Security Agreement (COMCASA), and Basic Exchange and Cooperation Agreement (BECA) are augmenting India’s military readiness, situational awareness, and capability for planning precision strikes. India secured a waiver from the Countering America’s Adversaries through Sanctions Act (CAATSA). India continues to benefit from access to advanced missile, propulsion, and guidance technologies through partnerships facilitated by its MTCR membership.
India’s missile systems have a range of up to 12,000 km, encompassing a vast arc that includes Western Europe, the Middle East, Central Asia, Moscow, Australia, and even the U.S. mainland. These ranges do not justify the notion of self-defense. The Agni missile series, particularly Agni-IV and Agni-V, already provides sufficient range and capability to deter China by covering key strategic and industrial centers across the country. However, India’s continued development of longer-range systems—such as intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs) with ranges exceeding 12,000 km—signals a shift beyond regional deterrence.
These advancements reflect India’s broader global ambitions, aiming to project power far beyond South Asia and establish itself as a major strategic player on the world stage. India is undergoing a significant transformation in its strategic arsenal, shifting from regional deterrence to global strike capability. Development of Agni-VI and the proposed Surya missile (with a range of 12,000 to 16,000 km) indicates a move toward true ICBM capabilities, well beyond the scope of regional defense. With an estimated range of 5,000–8,000 km, the K-5 missile, once deployed on Arihant-class or future S5-class SSBNs, will enable intercontinental strike capability from sea-based platforms, extending reach to China, Europe, Russia, and the U.S. mainland.
India is near completion of its K-6 (Kalam-6) submarine-launched hypersonic missile, capable of speeds up to Mach 7.5, a range of 8,000 km, and carrying both conventional and nuclear warheads. India’s rapid naval build-up, particularly the development and deployment of nuclear-powered ballistic missile submarines (SSBNs) such as INS Arihant (operational) and INS Arighat, along with the under-construction S4, and the future S5-class, significantly enhances its sea-based nuclear capabilities. These platforms are designed to provide a credible second-strike capability by ensuring survivability and retaliation from stealthy underwater locations.
India is actively pursuing hypersonic missile technology and Multiple Independently Targetable Re-entry Vehicles (MIRVs), which would allow a single missile to strike multiple targets—key components of a first-strike arsenal. India’s acquisition of Ballistic Missile Defense (BMD) systems and the deployment of the Russian S-400 creates a false sense of security, potentially encouraging Indian decision-makers to consider pre-emptive nuclear strikes, thereby undermining regional deterrence stability.
India’s long-standing power aspirations are visible through various actions in the military domain. Historically, it has used the ambition to attain regional hegemony, but these overambitious desires have severe repercussions for South Asia and globally. Advanced platforms such as ICBMs, hypersonic weapons, and nuclear-powered submarines could trigger a competitive arms build-up in South Asia, undermining arms control efforts and crisis stability. Development of offensive strategic systems capable of hitting targets far beyond India’s immediate neighborhood raises doubts about its NFU policy, leading to a perception of doctrinal ambiguity.
By acquiring capabilities that can reach the U.S., Europe, or East Asia, India signals global ambitions that could reshape its position from a regional actor to a more assertive strategic power, complicating global threat perceptions. India’s doctrinal shift and the rush for military modernization would seriously impact the balance of power in the region. This may create a gap for India to execute limited war strategies or surgical strikes options. After acquiring sufficient BMD capability, India might engage Pakistan in conflicts and cross its red lines, which may escalate the conflict to unforeseen levels of escalation.
The development of hypersonic missiles, ballistic missile defense systems, enhanced space-based intelligence and surveillance assets, and the deployment of nuclear-powered submarines armed with ballistic missiles all point toward a posture inconsistent with a purely defensive doctrine. India’s military modernization reflects a shift toward strategic ambitions beyond South Asia, carrying profound implications for both regional stability and the broader global strategic equation. If left unchecked, this trajectory risks triggering a regional arms race, undermining crisis stability, and weakening international non-proliferation norms. Moreover, the U.S.’s exceptional treatment of India may offer short-term geopolitical gains, but in the long run, it could prove counterproductive by enabling a power that may challenge U.S. interests or destabilize the very order Washington seeks to uphold.
