In the four days of Operation Sindoor in May 2025, the stars of India’s military response were not fighter jets. They were drones: surveillance UAVs watching targets, loitering munitions hovering and striking, and anti-drone systems knocking enemy drones down. In the seventeen months since, through mid-October 2026, the money has followed the lesson. Days after the ceasefire, the Defence Acquisition Council cleared emergency procurement worth about Rs 40,000 crore. The 2026-27 Budget raised defence spending 15% to Rs 7.85 lakh crore. And the armed forces have signalled buying plans worth nearly Rs 10 lakh crore in the years ahead. India’s defence tech startups have never had a moment like this.
What Sindoor actually proved
Every few decades, a conflict changes what armies buy. For India, Sindoor was that conflict. It showed that cheap, numerous, smart machines can do jobs that once needed expensive, few, manned platforms. A Rs 50 lakh drone can find a target that a Rs 500 crore aircraft would have risked a pilot to find. It also exposed how much of this hardware India still imported, which turned “buy Indian” from a slogan into a procurement emergency, as Inc42’s analysis of the shift records.
Operation Sindoor did for Indian defence tech what 1991 did for the Indian economy: it ended the debate.
The money that followed
Three pools of money matter. First, the emergency procurement route: about Rs 40,000 crore approved on 16 May 2025, spent on exactly what the conflict showed India needed, surveillance drones, kamikaze drones and the systems to stop them, bought in months rather than the usual years. Second, the Budget: the first one after Sindoor raised the defence allocation 15% to Rs 7.85 lakh crore. Third, the pipeline: ThePrint reported in July 2026 on acceptance-of-necessity approvals approaching Rs 10 lakh crore, which is the military’s way of saying “we are cleared to negotiate for this”, spread over many years. Inc42 estimates the defence market itself will grow from $27 billion in 2025 to $40 billion by 2030, with nearly half the new money going to new-age tech: AI, autonomous systems, quantum.
The startups on the field
India had 78 defence startups founded between 2020 and 2025, and over a third of them build drones or unmanned systems, Mint’s review of the sector found. The names to know: ideaForge, the listed pioneer whose UAVs already serve the forces and which reported record orders after Sindoor; NewSpace Research and Technologies, working on swarm drones; Tonbo Imaging, whose sights and sensors aim weapons; Big Bang Boom Solutions, in anti-drone defence; and Sagar Defence, building unmanned boats. Behind them sits a longer tail of startups in electronic warfare, secure communications and AI targeting software.
How a startup actually sells to the forces
The front door is iDEX, the Innovations for Defence Excellence programme launched in 2018, which funds startups to build prototypes for stated military problems. Its newer ADITI sub-scheme puts up to Rs 30 crore behind critical deep-tech projects, from a Rs 750 crore outlay. Win a prototype, prove it in trials, and the emergency and normal procurement routes can follow. The catch is time: as one investor told Moneycontrol after Sindoor, defence R&D runs in decades, not quarters, and nobody should enter expecting a two-year payback.
Important note: the bottleneck has moved from invention to growth capital. Seed money for defence tech is now findable, but scaling a defence company, factories, working capital against slow government payments, still takes years to fund, as Outlook Business documented in January 2026. Order books are real; patience is still the price of entry.
Why this matters beyond defence
Military demand is doing for Indian drones, sensors and autonomy what defence programmes once did for the internet and GPS abroad: paying for the hard years. The civilian versions, in farming, logistics and mapping, ride the same supply chains. We traced the wider wave in Deeptech Rising, and the patient-money problem behind it in this year’s funding data.
What the forces are actually buying
Read the emergency orders and budget lines and a shopping list emerges:
There is also an export angle. India’s defence exports crossed Rs 23,000 crore in FY 2024-25, a record, and the startups that prove themselves with Indian forces become sellable abroad, where a proven-in-conflict tag is the best marketing a weapons system can have. Armenia buying Indian radars and the Philippines buying BrahMos missiles were the early signs; drones are next on that list.
A useful mental model for the sector: defence tech in India has moved from the science-fair stage to the procurement stage. For years the conversation was about whether startups could build serious military hardware at all. Sindoor answered that. The question of the next five years is narrower and more commercial: which of these 78-plus companies can manufacture at scale, survive government payment cycles, and keep winning repeat orders once the emergency money normalises. That is a business question, not a technology question, and it is where the winners will separate from the photo-ops.
