₹39,000 Crore Ghatak Program Could Finally Make Kaveri Relevant
The Indian government’s decision to clear a ₹39,000 crore program for the Ghatak UCAV comes at a moment when the Indian Air Force is dealing with a shrinking fighter squadron strength and increasingly complex threats from advanced air defence systems like the HQ-9. On the surface, this looks like a push into stealth drone warfare. But beneath that, this program carries a deeper objective: giving India’s long-struggling Kaveri engine a second, far more realistic chance at relevance.
Ghatak Is Not Just a Drone Program, It Is an Engine Revival Platform
Ghatak is being designed as a stealth unmanned combat aerial vehicle capable of first-wave strikes, particularly for suppressing enemy air defences and hitting high-value targets deep inside hostile territory. But its importance goes beyond its combat role. It offers India a platform where the Kaveri engine can finally be deployed without being forced to meet unrealistic fighter jet requirements.
The scale of the program matters. With plans for over 60 UCAVs and a ₹39,000 crore investment, Ghatak is not a technology demonstrator. It is a serious operational project. And every UCAV in that fleet represents a potential engine slot for an indigenous solution that has been waiting for deployment for over two decades.
Why Kaveri Failed Earlier And What Has Changed Now
The Kaveri engine’s failure in the Tejas program is well documented. It was expected to power a supersonic fighter aircraft, deliver high thrust, operate with an afterburner, and meet stringent weight and reliability benchmarks. It fell short on multiple fronts. As a result, India had to turn to foreign engines, primarily from General Electric, locking itself into long-term dependence.
What has changed now is not just the engine, but the expectations. Ghatak does not require supersonic performance. It does not need an afterburner. It does not need to win dogfights. As a subsonic stealth UCAV, its priorities are endurance, efficiency, and low infrared signature. These are areas where a modified Kaveri has a far better chance of succeeding.
The problem, in hindsight, was not just that Kaveri failed. It was that India tried to use it in the most demanding role possible.
Dry Kaveri As A Strategic Workaround Instead Of A Technological Leap
The “dry” Kaveri concept represents a pragmatic shift. By removing the afterburner and focusing on a thrust range of around 45 to 52 kN, the engine is being adapted for a role that aligns with its strengths. This is not a technological breakthrough in the traditional sense. It is a strategic workaround.
Instead of abandoning decades of investment, India is attempting to salvage and repurpose that effort into a domain where success is more achievable. In that sense, Ghatak is less about innovation and more about intelligent repositioning. It is about making the best possible use of what already exists.
Why Ghatak Matters To The IAF At A Time Of Dwindling Fighter Strength
The Indian Air Force is currently operating below its sanctioned squadron strength, and replacing that gap with new fighter jets is a slow and expensive process. Ghatak does not replace fighter aircraft, but it changes how effectively they can be used.
By taking on high-risk first-wave missions, such as suppressing enemy air defences and striking radar and missile sites, Ghatak can reduce the burden on manned aircraft. Missions that would otherwise require sending pilots into heavily defended airspace can now be handled by unmanned systems.
This allows existing fighters like the Rafale and Su-30MKI to be preserved for roles where human decision-making and air superiority are critical. It also means fewer sorties are needed from a limited fleet to achieve the same operational objectives.
In a potential conflict scenario, Ghatak can act as a force multiplier. It can open corridors by neutralising enemy air defence networks, making it safer for follow-on strikes. This does not solve the squadron shortage on paper, but it makes a smaller force significantly more effective and survivable in practice.
₹39,000 Crore Creates Guaranteed Demand And Ecosystem Push
One of the biggest problems with indigenous defence projects in India has been the lack of scale. Without guaranteed orders, technologies struggle to transition from prototype to production. The Ghatak program changes that dynamic.
With an initial requirement of over 60 UCAVs, the demand for engines, components, and support systems becomes real and immediate. This creates pressure to build a manufacturing ecosystem that can sustain production at scale.
Public sector players like Hindustan Aeronautics Limited and private firms involved in precision engineering and components will have to align around this program. For the first time, India has an opportunity to build not just an engine, but an entire ecosystem around it.
Engine Remains The Biggest Risk In The Entire Program
Despite the optimism, the risks are clear. The Kaveri engine, even in its dry form, has not yet proven itself in operational conditions. It has not undergone full-scale flight integration on a combat platform. Its long-term reliability, maintenance cycles, and performance consistency remain untested in real-world scenarios.
If these challenges are not resolved, the program could face delays. There is also the possibility that India may once again have to rely on foreign engines, at least in the initial phases. That would dilute the very objective of achieving engine independence.
The lesson from Tejas still looms large. Engine development is not just a technical challenge. It is a test of sustained execution over time.
Strategic Implications For India’s Defence Autonomy
The outcome of the Ghatak program will have implications far beyond UCAVs. If Kaveri succeeds in this role, India will take a meaningful step toward reducing its dependence on foreign engine suppliers. It will also gain confidence in its ability to develop and deploy complex propulsion systems.
If the engine only partially succeeds, a hybrid model may emerge where indigenous and foreign systems coexist. Even that would represent progress compared to complete dependence.
If it fails, India will still gain a capable UCAV platform, but the core vulnerability in engine technology will remain unresolved.
Conclusion
The ₹39,000 crore Ghatak program is being presented as India’s entry into stealth drone warfare. But its real significance lies elsewhere. It is a test of whether India can finally close one of the most persistent gaps in its defence ecosystem.
Kaveri may never become the engine it was once envisioned to be. But through Ghatak, it has a chance to become something far more important: an engine that actually enters service. And for India’s defence ambitions, that may be the breakthrough that matters most.
