How India Lost a Nuclear Spy to America — The Real Story of Nambi Narayana
Times Life | June 14, 2025 1:39 AM CST

In the 1990s, India stood on the brink of a space revolution. It was building its own cryogenic engine, a piece of technology that could place India shoulder-to-shoulder with the space superpowers — the US, Russia, and China. At the heart of that mission was a scientist, a man trained at Princeton, courted by NASA, and wholly devoted to India’s future: Nambi Narayanan.
But instead of celebrating his genius, India threw him into a dark cell.

He wasn’t selling secrets. He was about to build something the world didn’t want India to have. This is not just a story of wrongful arrest — it’s a story of geopolitics, sabotage, and betrayal from within. The man we labeled a spy? He was probably the one being spied on. The Man India Should Have Protected Nambi Narayanan wasn’t just another ISRO scientist. In the 1970s, he brought liquid propulsion technology to India when solid fuels were the norm. He later developed the Vikas engine, which powers ISRO’s PSLV and GSLV launch vehicles — rockets that launched Chandrayaan, Mangalyaan, and India’s entire modern space fleet.
Despite being offered lucrative positions in the US after his stint at Princeton, Nambi chose to return. For him, nation came first. But India didn’t return the loyalty. The Real Threat: Cryogenic TechnologyCryogenic engines are game changers — they allow rockets to carry heavier payloads and reach deeper space. In the early 1990s, India had struck a deal with Russia's Glavkosmos to buy cryogenic engine tech and develop it further.

But the US, fearing India’s missile capabilities, invoked the MTCR (Missile Technology Control Regime) and pressured Russia to cancel the deal. Denied access to global tech, India decided to build its own engine — and Nambi Narayanan was leading this sensitive, high-stakes project.
That’s when the trouble began. The 1994 Arrest: Fiction Over Facts In November 1994, Kerala police arrested Nambi Narayanan, accusing him of passing on rocket secrets to two Maldivian women allegedly linked to Pakistan. The narrative was tabloid gold: espionage, seduction, and betrayal.

But it was full of holes. The alleged “secrets” were not classified documents. The accused women were not spies. The ISRO tech in question was already publicly available in open-source literature. And yet, Nambi was tortured, kept in custody for 50 days, and publicly shamed.

His reputation was destroyed. His work — halted. And his country — silent. An Invisible Hand? The Role of Intelligence AgenciesMany experts and retired RAW officers now believe that the arrest was not just a case of police incompetence, but foreign interference. There’s speculation that the CIA was involved in derailing India’s cryogenic program.

  • At the time, India’s self-reliance in rocket technology was seen as a threat by global powers.
  • Some believe India’s Intelligence Bureau (IB) was either misled or manipulated into framing Nambi.
  • Nambi himself later hinted at external forces: “Some foreign agencies did not want India to succeed in cryogenics. And they succeeded, at least for some time.”
India didn’t just sabotage its own scientist — it played into the hands of those who wanted him gone. What Did India Really Lose? The fallout was catastrophic. ISRO’s cryogenic project was set back by nearly 15 years. India lost time, money, and prestige.

  • Between 1994 and 2010, India had to rely on foreign launch vehicles, costing the country millions of dollars.
  • The GSLV (Geosynchronous Satellite Launch Vehicle), which needed cryogenic capability, couldn’t fly effectively until 2014 — decades after initial development began.
  • During this time, China surged ahead, launching humans into space and preparing lunar missions, while India was busy undoing damage it did to itself.
Nambi later said, “If I hadn’t been arrested, we could have had cryogenic launches by the year 2000.” Instead, India fell behind — all because we believed a lie. The Exoneration That Came Too Late In 1996, the CBI found the charges to be false and fabricated. The Supreme Court declared Nambi innocent in 1998. But the damage had been done. His career never recovered. ISRO had already moved on.

In 2018 — nearly 25 years later — the Supreme Court awarded him ₹50 lakh compensation and ordered a probe into the conspiracy behind his arrest. Even then, Kerala’s government delayed action, refusing to admit its mistake.

No officer was punished. No agency took responsibility. No real answers emerged. America Wanted Him — And We Gave Him Away Before his arrest, Nambi had been offered roles by NASA and other Western space agencies. After the false charges, he was again approached indirectly — but he refused. He didn’t sell out even when his own country sold him out.

“I did not betray my nation. I was betrayed by it,” he once said, with the quiet dignity of a man who still loved the flag that abandoned him.

Rocketry: The Movie That Told the Truth In 2022, the film ‘Rocketry: The Nambi Effect’, directed and acted by R. Madhavan, brought his story to the limelight. It shook audiences. Many Indians learned — for the first time — that a man we once called a traitor had actually been a national treasure.

The film didn’t just reveal the injustice. It exposed how nations kill their own heroes — not with bullets, but with silence.

When Silence Is a WeaponNambi Narayanan wasn’t a traitor — he was the very reason India was on the verge of mastering cryogenic technology. He could’ve helped launch India into the space age much earlier. But instead, we broke him with false charges, ignored evidence, and let foreign interests win without firing a shot.

India didn’t lose a spy to America. It lost a brilliant mind to its own system’s failure. The project he led was derailed, our space program was delayed by over a decade, and the global advantage slipped away — all because we mistook a patriot for a pawn.

Today, we take pride in Chandrayaan and Gaganyaan. But we must also remember: those missions stand on the wreckage of one man’s ruined career. And while we eventually cleared his name, the years we lost — and the future we delayed — can never be reclaimed.

Because in the race to the stars, the real betrayal isn't falling behind — it’s turning against the people who would have taken you ahead.
