Exploring K340A: The SECRET COMPUTER of CHERNOBYL DUGA RADAR | Russian Woodpecker

Discover the story of the K340A, a one-of-a-kind computer that powered the Soviet Union's ambitious Duga radar system during the Cold War. Designed in 1966 and based on the Residue Classes System, it achieved a performance of 1 million operations per second, making it allegedly the fastest second-generation computer ever built. After the Chernobyl disaster, Duga was shut down, and this once-superior machine now stands forgotten in its datacenter, still guarding its secrets. This is the first-ever documentary to reveal details about its history, unique hardware, architecture, and operation.

And it’s the first of stories from our nearly 10-year research into Duga, which we believe will finally answer some long-standing questions about this mysterious place.
