The Indo-Pacific's strategic geography has changed in the final week of May 2026 and it wasn't in a naval standoff or a diplomatic summit, but instead in a defence secretary's disclosure at a Singapore security forum. Addressing the Shangri-la Dialogue, the Defence Minister of India, Rajnath Singh called his Vietnamese counterpart general to inform him that the BrahMos missile deal with Vietnam had been inked a deal worth around $629 million, which also includes training and logistical assistance. Equally, what he went on to say caught people's attention: Talks with Indonesia were in the final phase, he said.

Three countries. One missile. A total deal value of over $1.3 billion. And a geopolitical footprint that is changing the nature of deterrence in the most disputed waters in Asia.

It was not the end of the BrahMos story. It started in January 2022 when the Philippines became the first country outside India to sign up for the system, a $375 million deal for three batteries of shore-based anti-ship missiles that was Manila's largest coastal defence spending in decades. That sale took years to finalise, and multiple factors such as weather, logistics issues and a deadlock in the NDA put off the first lot's delivery until April 2024, when it arrived on an Indian Air Force C-17 transport aircraft. In April 2025, a second battery was in. The speed of what's happened since is another story.

Diplomacy is not the only thing that's different from 2022. It has been proven in battle.

Operation Sindoor was a military exercise carried out by the Indian Armed Forces in May 2025 to counter Pakistan in response to the terror attack at Pahalgam, which resulted in the deaths of at least 26 civilians. The exercise turned into the first live combat debut of the BrahMos missile. The Indian army fired the supersonic cruise missile BrahMos on the morning of 10 May, hitting 11 airfields in Pakistan in 45 minutes. Pakistan's air force was temporarily paralysed and, as later revealed, Islamabad soon sat at the ceasefire table. Defence analysts and foreign procurement officials noted. The missile was not only a paper success, but a real success against air defence under contested conditions in the field with documented results.

According to military analysts, the operation showed the world the missile's capability to fly through active air defence systems in a real combat scenario. That separation between a marketable capability and a proven capability is exactly what made a difference for buyers throughout Southeast Asia and other regions.

The economics were just as lacking in credibility. In April 2026, the Ministry of Defence shared the latest statistics on Defence exports, reporting that India's overall defence exports in FY 2025-26 hit a record high of ₹38,424 crore, up from ₹23,622 crore in FY 2024-25, a 62.6 per cent increase. The company BrahMos Aerospace has itself reported revenues of over ₹5,200 crore in FY 2025-26 with export orders of ₹4,000 crore in that year alone. The new production site at Lucknow was inaugurated in mid-2025 and has already started the production of the first lot of BrahMos missiles, one year after the commissioning date. The production of the Nagpur plant is being ramped up separately to manufacture more than 100 missiles a year.

This was not apart from the global demand. Private sector exports stood at close to half of the total defence exports, at ₹17,352 crore in FY 26, a 54 per cent year-on-year increase. This industrial momentum provided about 1.5 lakh employment opportunities and helped generate profits which were invested in future technologies like AI-powered autonomous swarms and hypersonic glide vehicles. India is currently exporting defence equipment to more than 90 countries. It is the flagship of the BrahMos, and how it is moving!

Beyond the actual purchase of hardware, the strategic logic behind Southeast Asian purchases should not be overlooked. Vietnam, Indonesia and the Philippines aren't just purchasing missiles. They are purchasing a type of deterrence architecture that takes into account the unique geography of the South China Sea, of islands, chokepoints and disputed maritime zones.

If the missile is fired from islands held by Vietnam, BrahMos would be able to reach almost all the islands that China has occupied or bases that it has constructed in the South China Sea. The same geometry applies to the Philippines where the majority of the islands that are being claimed by Manila and occupied by Beijing are in the range of Filipino held positions. That's no coincidence. That is the exact operational logic that makes the system appealing to those who are the buyers' main concern in maritime affairs is Chinese assertiveness.

China's stance in these conflicts is well known and has hardly changed. Beijing has dismissed the 2016 UNCLOS arbitral tribunal decision that challenged its South China Sea claims and Chinese Coast Guard incursions into waters Beijing claims as its own have been reported in Vietnam, Indonesia and the Philippines, including a Chinese Coast Guard law that allows for the use of lethal force in the relevant waters. In that context, the ability of a coastal missile to reach surface targets at a range of more than 290 kilometres, at speed Mach 2.8, sea-skimming flight profiles with fire-and-forget guidance is no arms race indulgence. This is an inexpensive denial tool.

The developing trend, analysts say, is that of a "BrahMos Arc" in the South China Sea a web of power projection down from the coast to offset China's naval tonnage instead of trying to compete with it on the high seas. It is similar to the larger Indo Pacific strategy of smaller states seeking to raise the costs of coercive naval activity through precision strike capability.

The special geopolitical significance of this arc is the fact that it is being constructed by them. India is not a treaty ally of the Philippines, Vietnam or Indonesia. There are no military bases in the region. It's all dependent on the nature of its hardware and the strength of its defence ties. The BrahMos export plan is a well-crafted strategy to create a "Necklace of Diamonds" as it is termed by analysts at Asia Times — a plan of defence, diplomatic and economic ties with China's maritime periphery, and Southeast Asia its first bet. The comparison is stark: it's the same as China's Belt and Road port-building; the only difference is that the tool is missile sales instead of infrastructure financing.

The BrahMos Aerospace becoming an export enterprise is a milestone towards the longer journey of Indian defence manufacturing from a commercial and industrial perspective. Throughout its life, the missile was considered a strategic national asset – too capable, too geopolitically charged and too sensitive to place in foreign hands. For years, India had been wary of selling to Vietnam and Indonesia in particular, and was mindful of not provoking Beijing while Sino-Indian relations remained in a managed equilibrium. China's military aggression at LAC, Ladakh, in 2020, changed New Delhi's calculations on arming other nations that are under Chinese pressure.

The resultant change has been swift. In December 2025, Indonesia reportedly signed a contract for three coastal defence batteries valued at US$300 million that were said to be scheduled for delivery in 36 months, which was confirmed during the Shangri-La Dialogue as India's Defence Secretary said the talks were in the final stages. Earlier, Defence Minister Rajnath Singh had presented a model of the BrahMos missile to his Indonesian counterpart Sjamsoeddin during the third Defence Ministers' Dialogue between India and Indonesia held in October 2025, a clear indication of the symbolic nature of the deal.

There are more layers of complexity that accompany Vietnam's deal. Despite the fact that Hanoi has extensive economic ties with Beijing (China is Vietnam's largest trading partner), it has been more adamant than other ASEAN countries against the Chinese maritime encroachments. Vietnam has been keeping up its close economic ties with Beijing, but has nevertheless worked to diversify its security ties and beef up its coast guard presence in the disputed waters. The BrahMos purchase is an indication of Hanoi's hedging policy coming to their military purchases. It strengthens New Delhi's relationship with a nation that not only shares a border with China, but has a long history of conflict over China.

This story already has an extended-range dimension, but it's not public yet, it's about to become the next chapter. According to the reports, the Philippines has been promised the Extended Range variant of BrahMos by India which will push the engagement range beyond 400 kilometres and change the entire operational geometry of maritime defence operations over contested waters. The original export variant's range was limited to about 290 kilometres as per Missile Technology Control Regime limitations. Since India is a full member of the MTCR since 2016, gradually, the capability to deny has expanded and the ER variant is a stepping stone in the direction of denial capability for any buyer who operates near the contested island chains.

It is an opportune time to add the economics of Indian defence transformation in the whole context. India was one of the largest arms importers in the world, getting more than 60 per cent of its weapons from Russia 10 years ago. The defence production has now grown to ₹1,54,000 crore in FY 2025, which is 3.2 times higher than the previous 10 years with 65 per cent of equipment being indigenous. While the BrahMos is the most visible change, it is on the back of a larger industrial policy and procurement rules and export licensing changes that have been put in place since 2014. According to analysts, the export revenues for BrahMos could reach $5 billion by the end of the decade as production expands and hypersonic BrahMos-II is slated for trials in 2026-27.

What's lurking behind all of this is whether or not it's strategic intent or not. India has always portrayed itself as a non-aligned power, a non-block country, a nation that does not make hard security pledges, and that deliberately cultivates relations with China, the United States and Russia in a fuzzy, non-committal way. It is not a policy of neutrality to sell supersonic missiles to three of China's maritime neighbours at once, which can reach Chinese-occupied islands. It's the architecture of deterrence, through commercial ties not formal alliances.

That's, in a way, a more lasting type of influence. Countries that purchase and operate BrahMos establish training ties, maintenance vulnerabilities, and logistics and interoperability with Indian defence systems. The missile is not simply a sale, but the start of a working relationship. It is also, for the Philippines and Vietnam and Indonesia, something that alliance organizations may not always be able to offer: a credible, proven ability to increase the costs of confrontation without the political baggage of a treaty commitment.

So by the end of May 2026, what did the Shangri-la Dialogue yield: not just a missile deal, but the recent confirmation of a new Indo-Pacific security trend. For India, it has emerged as a “significant” supplier of arms to the most strategic states of the area. It has been through one war without losing its missile system. Its lines are in operation. And the buyers, it seems, are still lining up.
