India embarks on multi-billion drone purchases post Operation Sindoor but key deficiencies in its drone-verse remain unresolved.

In October, Russia fielded the newest technological breakthrough of its four-year war with Ukraine—the Filin (Eurasian eagle-owl), a ground-launched jet-powered drone which can fly the Delhi-Mumbai air distance, around 1,200 kilometers, at a speed of 800 kmph.
The Filin flies at twice the speed of propeller-driven drones like the Shahed-136 which Russia also uses, more importantly, the satellite-steered munition costs roughly USD 50,000, a fraction of a USD 2 million Tomahawk cruise missile. This means Russia can build thousands of Filins to generate ‘precision mass’ – where precision attacks can be carried out in large numbers at lower costs than conventional missiles.
The IAF has known the force-multiplier capabilities of jet-powered drones – it ordered 200 Sureshastra Smart Unmanned Munitions Systems (S-UMS) made by Veda Aeronautics in August 2024. Now, over the next few weeks, the Indian Army will begin trial evaluations of jet-powered kamikaze drones from a dozen Indian firms.
The army hopes to buy 540 such high-speed drones, its largest purchase of this weapon class. These are the newest big-ticket drone purchases since Operation Sindoor last year, where, in the words of Air Chief Marshal AP Singh, drones went on from being ‘eyes in the sky’ to ‘claws in the sky’.
The 88-hour conflict was among the world’s first instances of non-contact kinetic warfare, in which adversaries did not cross borders to do battle. Army drones hit Pakistani terror training camps, IAF Brahmos missiles shattered runways and destroyed hangars with aircraft inside them, and IAF Harop one-way attack drones plunged into Pakistani radars and command posts.
India’s drone arsenal is surging. Over the next five years, the three services will acquire drones cumulatively worth over 1.5 lakh crore (over USD 15 billion), or roughly half the cost of its biggest ever defence deal for conventional hardware—an upcoming buy of 114 Rafale fighter jets from France.
Jet-powered drones are the most significant accretion of tri-services strike capabilities since the Brahmos cruise missile was inducted in the 2010s. Other buys encompass a full spectrum of operations, from sea level to the stratosphere— High Altitude Pseudo Satellites (HAPS), High Altitude Long Endurance (HALE) UAVs, Medium Altitude Long Endurance (MALE) UAVs for surveillance missions, Collaborative Long Range Destructive Swarms (CLRDS), and jet-powered canisterised drones launched from IAF cargo aircraft, which would enable the IAF to hit targets in China, across the heavily-defended expanse of the Tibetan plateau. The IAF plans to acquire over 100 Ghatak stealth bomber drones worth over Rs 60,000 crore to complement its manned fighters.
The army plans to train and deploy over 100,000 drone operators to operate a range of surveillance and strike drones inducted by its 385 infantry battalions. The Indian Navy was the first service to fire missiles, in the 1971 Indo-Pak war. It is now looking to acquire a new class of long-range jet-powered drones costing a fraction of ship-launched cruise missiles. The navy is also inducting large fleets of unmanned surface vessels (USVs) which will handle hazardous tasks like mine clearance and launch kamikaze strikes on enemy warships using missiles and explosives.
Acquiring drones off the shelf, it would seem, is the easy part. The focus has been on the fighting edge rather than the long tail of logistics, components, doctrines and industrial capacity.
THE MISSING MASS
During the 40-day US-Iran conflict which began on February 28, Iran launched multiple attacks on US air bases and ports across seven Gulf Arab countries, making up for its missing air force and navy with thousands of drones and missiles stockpiled in underground missile cities. This year, Russia and Ukraine are both set to produce over 6 million (60 lakh) drones each year.
