The Mumbai Engineer Who Helped Build the B-2 Bomber—And Then Sold Its Secrets to China
Genius Turned Traitor
The story of Noshir Sheriarji Gowadia is a dramatic tale of genius, ambition, betrayal, and the complex intersections of global technology and espionage. Born in Mumbai in 1944, Gowadia would ascend to the very heart of American military engineering, helping develop the iconic B-2 Spirit stealth bomber—a plane that remains one of the world’s most sophisticated aircraft, symbolizing America’s military might. Decades later, Gowadia would be at the center of one of the United States’ most damaging cases of technological espionage, passing closely guarded secrets to China and other nations, with consequences that continue to echo in today’s geopolitical landscape.
Rise to the Top: From Mumbai to America’s Stealth Program
Noshir Gowadia’s journey began in India, but his ambition and intellect quickly led him to the United States. After completing his engineering studies at the Indian Institute of Technology (IIT Bombay), he emigrated, eventually joining Northrop (now Northrop Grumman), the American defense giant.
At Northrop, Gowadia became a key member of the team designing the propulsion system and stealth features for the B-2 Spirit bomber. The B-2 was a triumph of innovation—capable of penetrating enemy airspace undetected thanks to its unique shape, radar-absorbing materials, and sophisticated engine exhaust systems that minimized its infrared signature. Gowadia was lauded for his contributions, earning respect as a pioneer in low-observable (stealth) technology.
The B-2 Spirit: America’s Technological Crown Jewel
The B-2 Spirit was more than just another bomber. It was (and remains) a symbol of American technological superiority—a flying wing capable of slipping past the world’s most advanced air defenses. First flown in 1989, the B-2 could deliver both conventional and nuclear payloads, and its effectiveness depended on maintaining the secrecy of its design.
A crucial element was its ability to evade radar and infrared detection, allowing it to operate in contested airspace with impunity. The science behind this “invisibility” was cutting-edge—and closely guarded. Only a handful of engineers, including Gowadia, truly understood its most sensitive aspects.
A Fatal Shift: Consulting, Greed, and Espionage
After leaving Northrop in 1986, Gowadia established his own consultancy in Hawaii. At first, he worked on civilian projects and defense consulting contracts. But at some point in the early 2000s, his ambitions and financial desires took a dark turn.
According to U.S. prosecutors, Gowadia began marketing himself to foreign governments, claiming to possess expertise in advanced stealth technology. Between 2003 and 2004, he made several trips to China, where he met with officials involved in developing China’s next generation of military aircraft. Gowadia allegedly provided Chinese engineers with detailed advice on reducing infrared signatures on their missiles and aircraft—a critical stealth capability.
Investigators later discovered that he had pocketed over $100,000 for his services to China. The information he shared included detailed designs for exhaust systems and stealth features—technologies that took the U.S. decades and billions of dollars to perfect.
The Investigation: How the FBI Uncovered the Plot
The U.S. intelligence community, already on high alert for foreign espionage, noticed suspicious activity connected to Gowadia’s international travels. In 2004, the FBI launched a formal investigation, monitoring his communications and financial transactions.
A search of his Maui home in October 2005 turned up a treasure trove of evidence—over 200 classified documents, including blueprints and analysis relating to the B-2 and other sensitive defense projects. These materials were not just historical relics; they contained actionable intelligence that could dramatically enhance the capabilities of a rival power.
Gowadia was arrested and indicted on multiple counts, including violations of the U.S. Arms Export Control Act and the Espionage Act.
Trial and Conviction: The Cost of Betrayal
Noshir Gowadia’s trial was one of the most closely watched espionage cases in recent memory. Prosecutors accused him of “profiting from the secrets of his adopted country,” while defense attorneys painted him as a misunderstood consultant who shared only unclassified information.
The jury, however, was not swayed. In August 2010, Gowadia was convicted on 14 counts, including espionage, illegally exporting defense technology, and money laundering. The court heard evidence that he had not only sold secrets to China but also offered his expertise to Switzerland, Israel, and Germany.
On January 24, 2011, he was sentenced to 32 years in federal prison. Judge Susan Oki Mollway said, “He sold out his adopted country, the country that gave him citizenship, education, and the opportunity to work on a program as sensitive as the B-2 bomber.”
The Fallout: Stealth Secrets and the Rise of China’s H-20 Bomber
Why does the Gowadia case matter now, years after his conviction? The answer lies in the accelerating arms race in stealth technology.
In May 2025, satellite imagery and intelligence reports revealed that China had made major advances in its own strategic bomber program. The Xi’an H-20—a large, flying-wing stealth bomber—has long been rumored to draw heavily from U.S. technology, specifically the B-2. While much of this is speculation, the timing and nature of China’s progress have reignited concerns about the damage done by Gowadia’s betrayal.
Experts believe that his insights into exhaust signature reduction and low-observable materials may have directly aided China in bridging the gap between American and Chinese stealth capabilities. In a world where information is as valuable as firepower, the theft of such secrets represents a critical breach of national security.
Broader Implications: Trust, Security, and the High Stakes of Modern Espionage
The story of Noshir Gowadia serves as a sobering reminder of the vulnerabilities that exist in even the most secure defense programs. It underscores the dangers of insider threats, the challenge of securing intellectual property, and the ever-present risk of espionage in a multipolar world.
For the U.S., it was a wake-up call—leading to tighter vetting, new security protocols, and a renewed focus on protecting sensitive information. For China, it represented a leap forward in military modernization. For the world, it was yet another chapter in the ongoing contest for technological supremacy.
A Lasting Legacy
From Mumbai to Los Angeles, from top-secret labs to foreign boardrooms, Noshir Gowadia’s journey is a case study in ambition gone astray. He helped build one of America’s most valuable strategic assets—then sold its secrets for personal gain.
Today, as the United States and China face off in a new era of great-power competition, the consequences of Gowadia’s actions continue to unfold. The saga of the B-2’s betrayal is more than a story of one man’s downfall; it is a warning about the high price of complacency in a world where secrets are always at risk.
