India’s Agni-VI: Beyond Deterrence
April 2026 brought new strategic developments in the security realm of South Asia. India is pursuing strategic capabilities like the Agni-VI intercontinental ballistic missiles (ICBM), with a projected range of 10,000 – 12,000 km and multiple MIRV capabilities. While Indian officials continue to frame it as an extension of their ‘credible minimum deterrence’ doctrine, these attempts at power escalation raise serious questions about whether it is about India’s defensive posture or offensive. As the Defense Research and Development Organization (DRDO), India remains ready for these developments, only awaiting government approval, these developments warrants scrutiny from the international community, especially the US and its allies, to scrutinize whether these developments align with regional stability or introduce new risks to global security and power projection.
The Agni-VI is known to be an advancement built on the Agni-V, which functions on an operational range of 5000 km, which would place Pakistan and China both within its range boundary. The other developments include the solid-fueled 10 MIRV warheads and Maneuverable Reentry Vehicles (MaRVs), further extending its reach. Predictably, such missiles, if fired from Indian launch sites, can easily strike targets across Europe, Russia, the western bounds of North America, and some parts of Africa. If this is not a threat to transcontinental security, then what is?
This clearly exceeds the requirement of the ‘credible minimum deterrence’ doctrine against Pakistan which has acquired operational missiles with the longest range limited to 2750 km, namely, the Shaheen-III. Similarly, China, which possesses a far larger nuclear arsenal in the region, advanced systems like the Dongfeng-41 (DF-41) ICBMs, which have a range of up to 15,000 km and can reportedly hold up to 10 MIRVs, allow strikes from deeper rear areas, seeking survivability but also signaling escalation dominance.
Formalized in 2003, India’s nuclear doctrine was based on no-first-use (NFU) and retaliation in response to nuclear, biological, or chemical weapon attacks. It has always focused upon a nuclear triad, i.e., land, sea, and air capabilities. However, India’s shift from Agni-III to Agni-V and now to Agni-VI suggests something meaningful. It means India now has improved precision, MIRV tech, and extended-range weapon systems compared to the past. On this, analysts have pointed out that India is displaying a shift from its earlier policy towards power dominance, which poses a serious threat to the region, especially to Pakistan and China.
China, even though possessing superior capabilities monitors India’s developments given their border tensions. For the US and its allies, amidst their defense ties and Quad with India, these developments may seem subtle to them but what they seem to be overlooking is that strategic partnership should not be bypassed by capability mismatches. Given that the US is always keen on controlling exports and diplomacy on managing missile proliferation, then it should hold India accountable for its expansive measures, given that India is not a signatory to the NPT and its arsenal is growing with each passing day.
The global non-proliferation regime promotes the practice of self-restraint and export controls. While all states have the right to defend themselves, the global non-proliferation regime believes in the prevention of arms race. India’s ambitions, if unchecked, could incentivize its developments further, threatening the already unstable order even more. What needs to be done is that India should be held accountable for its technological advancements; it should be restricted from modernizing its capabilities and extending its ranges, both of which antagonize the global non-proliferation regime. India should further seek to provide assurances on the safety, compliance and regulation of its growing strategic developments. All the stakeholders need to urgently hold multilateral dialogue to reach a broader unilateral Indo-Pacific strategy to ensure safety, compliance and survivability and outline restrictions in the growing arms race in the region.
In summation, the Agni-VI is a yet another extension of Indian missile range and is a step towards expansion of Indian strategic capabilities within and beyond the region. This not only poses a threat to the region but is also a threat to global security and is also a growing challenge to the global non-proliferation regime. To stop this from expanding and becoming more serious of a threat, the US and its allies with the inclusion of multilateral forums need to step up and restrict India from these developments moving on, and also to protect the strategic stability of the region.
