The Cold War’s deadliest idea wasn’t just a theory — it was built, tested, and launched from beneath the ocean.
In this episode of Archive Unknown, Nick Johnson traces the origins of the Polaris missile program, uncovering how America’s first submarine-launched nuclear weapon turned the concept of Mutually Assured Destruction into reality.
From Lockheed’s secret labs to test launches at sea — and the quiet notes his grandfather left behind — this is the story of the weapon that kept the Cold War cold.

How do you build a plane faster than a bullet?
In this episode of Archive Unknown, Nick Johnson traces the secret history of the SR-71 Blackbird — the spy jet born from Cold War fear and engineered to outrun every missile on Earth — and follows the hidden connections that link his grandfather’s career at Strategic Air Command to the fastest aircraft ever made.

For 30 years during the Cold War, Ken Johnson worked at Lockheed with top-level security clearance on projects like Polaris missiles, stealth aircraft, and more. Decades later, his grandson discovers a box of his personal files and belongings. Each episode investigates one item to uncover hidden stories of innovation, secrecy, and the Cold War’s mysterious legacy.

In 1955, Lockheed’s Skunk Works built a secret runway in Nevada’s Groom Lake to test the U-2 spy plane. It would become Area 51, birthplace of the Blackbird and decades of classified innovation.
Host Nick Johnson uncovers the true origins of America’s most mysterious base—linking his grandfather’s work at Lockheed to nuclear tests, surveillance breakthroughs, and the myths that still surround the desert today.

In 1960, a small orange parachute drifted from orbit carrying the first film ever returned from space. Its mission was classified — part of Project CORONA, America’s first spy-satellite program.
From Sputnik to Discoverer XIII, this episode uncovers how the U.S., Lockheed, and the CIA built secret eyes in the sky, and how a fragment of parachute in my grandfather’s box connects to the birth of satellite reconnaissance — and the dawn of the space-age Cold War.

Archive Unknown begins in the Nevada desert with Operation Plumbbob—the 1957 nuclear weapons tests that defined the Cold War. Through my grandfather’s classified work and the documents he left behind, we uncover the hidden history of America’s atomic age.
