The headlines are singing a familiar, dusty tune. Russia offers the Su-57 to India. Promises of "co-production" and "technology transfer" are being dangled like shiny lures in front of a hungry fish. Most defense analysts are salivating at the prospect of India finally getting its hands on a fifth-generation fighter to counter China’s J-20.
They are wrong. They are falling for a geopolitical sunk-cost fallacy that has plagued New Delhi for decades.
The Su-57 is not the solution to India’s air superiority gap; it is a high-priced anchor that will drag the Indian Air Force (IAF) into a decade of maintenance nightmares and technological obsolescence. If India signs on the dotted line, it isn't buying a fighter jet. It’s buying a liability.
The Stealth Myth and the "Sensor Fusion" Lie
Let’s start with the most glaring issue: the Su-57’s stealth—or lack thereof. In the world of fifth-generation warfare, the only thing that matters is the Radar Cross Section (RCS). If you can’t get your RCS down to the size of a marble, you aren't flying a stealth jet; you’re flying a very expensive target.
The Su-57 uses a "level of stealth" approach. That is a polite way of saying the airframe has too many gaps, exposed engine rivets, and poorly designed intake ducts to actually hide from modern AESA radars. While the F-35 and F-22 are designed with an obsessive focus on low observability from every angle, the Su-57 is a patchwork quilt of fourth-generation aerodynamics with a fifth-generation skin.
I have watched defense procurement cycles for twenty years. I have seen the same pattern: a nation buys a "stealth" platform based on laboratory specs, only to realize in theater that the electronic warfare suites of the adversary see them coming from three hundred miles away. Russia’s "side-looking" radars and infrared search and track (IRST) systems are impressive on paper, but they are band-aids for the fact that the plane itself is loud and bright on a radar screen.
The Co-Production Scam
The word "co-production" is the ultimate sedative for Indian policymakers. It sounds like sovereignty. It sounds like "Make in India." In reality, it is a mechanism for Russia to offload the crushing R&D costs of a platform its own military can barely afford to field in significant numbers.
Look at the FGFA (Fifth Generation Fighter Aircraft) program. India poured nearly $300 million into preliminary designs before pulling the plug in 2018. Why? Because the "work share" was a joke. Russia wanted the cash, but they didn't want to share the source code for the flight control systems or the sensitive engine crystal technology.
True technology transfer happens when you gain the ability to iterate and improve. Russia’s version of technology transfer is sending kits for India to screw together in a hangar in Nashik. That isn't building an aerospace industry; that’s expensive LEGO.
If India wants a domestic fifth-generation fighter, it needs to stop looking for shortcuts in Moscow. Every rupee spent on Su-57 localization is a rupee stolen from the AMCA (Advanced Medium Combat Aircraft) project. You cannot build a future while clinging to a partner that is technically stuck in the late 1990s.
The Engine Problem No One Talks About
The Su-57 is currently flying on the AL-41F1 engine. This is an upgraded version of the engine used in the Su-35. It is a fourth-generation engine in a fifth-generation suit. The "real" engine, the Izdeliye 30, has been "just around the corner" for years.
Without the Izdeliye 30, the Su-57 cannot achieve true supercruise—the ability to fly at supersonic speeds without using fuel-chugging afterburners. Without supercruise, you lose the energy advantage in a dogfight. You lose the ability to intercept high-speed threats.
Betting on Russian engine timelines is a fool's errand. The Russian defense industry is currently cannibalizing its high-tech sectors to sustain a war of attrition in Ukraine. The precision machine tools required for high-performance turbine blades are becoming increasingly scarce under international sanctions. To believe that Russia will deliver a world-class engine to India on schedule requires a level of optimism that borders on the delusional.
The Sanctions Trap
We must address the elephant in the room: CAATSA (Countering America's Adversaries Through Sanctions Act).
The global financial system is currently weaponized against Russian defense exports. If India commits to a multi-billion dollar Su-57 deal, it isn't just buying hardware; it is inviting a systemic confrontation with the U.S. financial system.
Is the Su-57 worth losing access to GE engines for the Tejas Mark 2? Is it worth jeopardizing the MQ-9B Predator drone deal? Or the co-production of F414 engines?
The math doesn't add up. The opportunity cost of the Su-57 is the entire Western defense partnership that India has spent fifteen years cultivating. You don't trade a seat at the table of global aerospace leaders for a second-hand seat in a shrinking Russian sphere of influence.
The Maintenance Black Hole
Ask any IAF officer about the availability rates of the Su-30MKI. It is a magnificent aircraft, but it spends far too much time on the ground waiting for spare parts from Russia. The logistics chain for Russian hardware is notoriously opaque and inefficient.
The Su-57, with its complex composite skin and advanced avionics, will be ten times harder to maintain than the Su-30. If Russia cannot provide adequate spares for its most exported fighter, what makes anyone think they can support a low-volume, high-tech platform like the Su-57 while their domestic production lines are under siege?
India needs "Available Sorties," not "Paper Tigers." A fleet of 50 Su-57s with a 40% mission-capable rate is a strategic liability. You are better off with a larger fleet of Rafales that actually fly when you push the button.
The Real Threat: China’s J-20
The argument for the Su-57 is usually: "We need it because China has the J-20."
This is the wrong way to look at the problem. You do not counter a stealth fighter solely with another stealth fighter. You counter it with an integrated network of high-frequency radars, long-range surface-to-air missiles, and electronic warfare nodes.
If the J-20 is the threat, the answer is to accelerate the S-400 integration (despite its own issues) and invest heavily in indigenous sensor networks. Buying a compromised Russian jet to "match" a Chinese jet is an emotional response, not a strategic one.
The J-20 is being produced at a scale Russia cannot dream of. China is reportedly churning out forty to fifty J-20s a year. Russia has struggled to deliver more than a dozen Su-57s to its own air force. In a war of attrition or even a localized conflict, volume and reliability win. The Su-57 offers neither.
A Better Path Forward
The status quo says India must buy Russian to maintain "strategic autonomy." I argue that buying Russian is currently the greatest threat to that autonomy.
True autonomy comes from owning the intellectual property. It comes from having a supply chain that isn't vulnerable to the whims of a single sanctioned nation.
India should double down on the Rafale—a platform that is proven, has a high availability rate, and carries the Meteor missile, which is arguably the best air-to-air weapon in the world. Simultaneously, New Delhi must treat the AMCA project with the same urgency as a Manhattan Project.
Stop looking for a savior in the form of a Russian sales pitch. The Su-57 is a ghost of an old era of defense procurement. It represents a world where India was a junior partner, grateful for whatever scraps of tech were tossed its way. That India is dead.
The Su-57 offer isn't a gesture of friendship; it’s a desperate attempt by a declining power to find a financier for its failing projects. India is too big, too wealthy, and too important to be Russia’s venture capitalist.
Walking away from the Su-57 isn't a sign of weakness. It is the first step toward actual military independence. The "lazy consensus" wants you to think this is a missed opportunity. The truth is that it’s a bullet India needs to dodge.
India has spent sixty years being a captive customer. It’s time to be a partner instead. And that partnership isn't waiting in Moscow. It’s waiting in the labs in Bengaluru and the joint ventures in Paris and Washington.
The era of the Russian fighter in the Indian sky is over. Let it stay that way.
