India can buy a jammer, a laser, a catcher net and a micro-missile. The harder purchase is the second in which those tools agree that the same object is a threat. After Operation Sindoor the services started saying the quiet part. An integrated, layered shield against drones, loitering munitions and missiles. The Defence Acquisition Council’s Rs.52000 crore tranche put Akash Tarang electronic warfare on Army formations, kamikaze drones on the list and a high-altitude pseudo-satellite in the Air Force column. Mission Sudarshan Chakra is the political name for a national grid. The technical names already exist. Akashteer is the Army’s air-defence picture. IACCS is the Air Force’s. Trigun is the Navy’s. A Joint Air Defence Centre is supposed to see all three. One site was called fully wired in early 2025. The rest of the map is still being soldered. A sensor that cannot hand a track to a shooter is a museum piece that happens to be switched on.
A working counter-drone brain does five jobs in order. Detect with radar, radio-frequency listeners and cameras that do not all stare at the same false bird. Fuse those tracks so one drone is one icon, not four arguments. Decide who owns the shot when the object is over a city, an airfield or a brigade. Soft-kill first when spectrum and law allow. Hard-kill when they do not. Directed energy is between those layers if the beam can be aimed without cooking a civil radar. BEL’s D-4 family and the Integrated Drone Detection and Interdiction System already try to walk that chain. IDDS Mark-II is being pushed with a stronger laser. Solar Defence’s Bhargavastra puts rockets and micro-missiles on a vehicle with its own C4I cabin and claims it can plug into service networks. Zen, ideaForge, Big Bang Boom and imported kits from Rafael and DroneShield fill depots. Market maps count sixty systems and forty-odd makers. That is plenty of hardware. It is not one architecture. GaN front-ends and high-end FPGAs still come from abroad. Protocols differ. A formation jammer that cannot talk to an IAF base radar will paint the same swarm twice and miss the cheap one that flies between them.
Airports expose the civilian hole. CISF guards seventy-two of them and has begun Army-backed training and quick-response teams after drone scares in the north. Detection at a perimeter is not authority to jam in a terminal control area. Spectrum belongs to one ministry. Neutralisation belongs to another. The airport operator wants the runway open. The controller wants a clean scope. Police want an arrest. A military C-UAS vehicle parked at a civil gate does not automatically inherit a legal shot. Hanover, Tan Son Nhat and Williamtown have already shown what a single unidentified quadcopter does to a schedule. Delhi, Mumbai, Amritsar and Srinagar live with that risk every festival and every tense week on the frontier. Refineries, ports, stadiums and power plants sit in the same legal fog. A national grid that stops at the cantonment fence is half a grid.
Indigenous firms can supply the boxes. They cannot supply the doctrine that tells an operator at 2 a.m. which icon is hostile and which service may fire. IIT Kanpur’s new military drone hub is aimed at jam-resistant links and a three-layer kill chain. That is useful engineering. The Forward Vector is command. Until Akashteer, IACCS and the airport police radio share a live picture and a written rule for the last second, India will keep adding radars and still lose time. Drones are cheap. Confusion is expensive. One brain is the system worth funding next.
