Interceptor economics: why India's counter-drone budget will go to low-cost systems
An interceptor now costs 20 to 100 times the drone it destroys. That gap shaped the May 2025 conflict and the procurement decisions since, and closing it is a problem sized for early-stage companies.
Counter-drone defence covers the full sequence against hostile unmanned aircraft: detection, decision and defeat. The field is now organised around a measure that did not have a name five years ago. Interceptor economics is the unit cost of the interceptor relative to the unit cost of the threat, adjusted for magazine depth, meaning how many interceptors are in stock, and reload rate, meaning how quickly industry can replace them.
The measure matters because the ratio reversed after 2022. A Shahed-136 class one-way attack drone costs $20,000 to $50,000 by the open estimates that CSIS and RUSI cite. The legacy interceptors fired at it cost from about $1 million for a Patriot round to $5.3 million for a PAC-3 MSE, according to the cost tables JINSA published in July 2025. Iran can build roughly 200 Shaheds a month for a few million dollars; destroying those 200 with PAC-3 interceptors would cost more than a billion dollars. By mid-2025 the US Army's PAC-3 MSE stock had fallen to about a quarter of its minimum threshold, with three-year production lead times.

India's experience in May 2025
On the nights of 7 to 10 May 2025, Pakistan launched 300 to 400 drones at 36 locations. India intercepted them, and the Defence Secretary afterwards described the episode as a reality check that exposed gaps in electronic warfare and counter-drone capability. What followed was fast by procurement standards: the Bhargavastra micro-missile counter-swarm system was test-fired within a week; DRDO's D4 counter-drone system was inducted in March 2026 with at least 72 percent indigenous content; a 30-kilowatt laser was field-tested with technology transfer to private industry announced; and in July 2026 the Defence Acquisition Council cleared about ₹52,000 crore of procurement with anti-drone electronic warfare, air-defence missiles and counter-drone systems as stated priorities. The Home Ministry separately decided to equip every civil airport with counter-drone systems, phased from Delhi, Mumbai, Srinagar and Jammu.
Interceptor economics
The cost of the shot against the cost of the threat, multiplied by how many shots a raid needs. Change the assumptions to see how the ratio moves.
Reference points: one-way attack drones of the Shahed-136 class are estimated at $20,000 to $50,000 (CSIS and RUSI, cited by open-source trackers); a PAC-3 MSE interceptor is listed at about $5.3 million and older Patriot rounds at about $1 million (JINSA cost tables, July 2025); Ukrainian FPV interceptors cost $1,000 to $2,500 and hit rates of 80 to 90 percent are reported by trade press; Pakistan launched 300 to 400 drones at 36 locations in one night during May 2025 (Ministry of External Affairs briefing). Wartime production and hit-rate figures are directional.
What has not yet been procured
One tier is missing from the systems India has inducted so far. India has electronic-warfare jammers, radar and passive detection, micro-missiles, guns and a laser programme. It has no autonomous interceptor drone at the ₹1 lakh to ₹4 lakh price point, which is the tier Ukraine built at industrial scale and the United States imported in one purchase of about 13,000 units in 2026. Ukraine's FPV-class interceptors cost $1,000 to $2,500, ship in the tens of thousands per month, and are credited with the majority of drone kills in some months; hit rates of 80 to 90 percent are reported, and we treat those as wartime claims rather than audited figures.
The second gap is software. The two largest acquisitions in the segment were of software companies: Dedrone, a sensor-fusion command-and-control platform, bought by Axon in 2024, and D-Fend Solutions, which does radio-frequency takeover of hostile drones, bought by Motorola Solutions for $1.5 billion in June 2026 on roughly $67 million raised. In India, the integration layer is owned by a defence public-sector undertaking and the startups build closed, vertically-integrated stacks. No Indian company yet sells an open decision layer that works across effectors.
Why jamming loses value
The threat is becoming resistant to electronic warfare. Fibre-optic FPV drones spool 10 to 30 kilometres of cable and cannot be jammed; Shahed-class autonomy removes the operator link altogether. Jammer-heavy stacks, which is most of what India has inducted, lose relevance against both. The defeat layer has to become kinetic and autonomous, which is why Ukraine's 2026 priority is optical terminal guidance for interceptors that works when GPS and radio are denied. India's analogue, an electro-optical seeker and proximity fuze that any interceptor maker could buy, does not yet exist outside one company's seeker line.
Sizing the demand
We sized the Indian counter-drone market from the number of sites to be protected rather than from a published market estimate. About 130 fixed military sites, 30 sensitive civil airports in the first phase of about 140, and roughly 65 critical-infrastructure sites: refineries, ports, nuclear plants. Fitted at ₹25 to ₹40 crore per military site and ₹8 to ₹35 crore per civil site, and adding mobile systems, a war-reserve magazine sized to ten Sindoor-scale nights across three commands, and state police, we arrive at ₹12,000 to ₹19,000 crore of counter-drone spend between FY27 and FY31. The software and fusion layer is typically 8 to 12 percent of system value. A seed-stage company taking a few percent of that layer, or supplying seekers and interceptor sub-systems, reaches tens of crores of revenue on conservative assumptions.
The cost comparison that created the problem also funds the solution. Defending one ten-night campaign with missiles at ₹1.5 to ₹3 crore a shot costs something over ₹10,000 crore. Defending it with a layered stack of electronic warfare, guns and ₹2 lakh interceptors costs a few hundred crore. A saving of that size is visible to any procurement authority.
What we are looking for
We are looking for three kinds of company: a fusion and command-and-control software team, independent of any one effector, selling airspace security to critical infrastructure and the airport programme; an autonomous-interceptor team with a flying airframe and terminal-guidance computer vision; and a seeker and fuze module supplier that treats every interceptor maker as a customer. The window is 12 to 24 months: the July 2026 approvals and the airport specifications will be contracted over FY27 and FY28, and the first Indian team to fly a sub-₹4 lakh autonomous interceptor against a Sindoor-class threat picture will have a strong claim on how the specifications are written.
