"디젤 잠수함이 미사일을 쏜다고요?" 세계가 깜짝 놀란 K-잠수함의 비밀

There is something that even the United States, which possesses nuclear submarines, could not achieve with diesel engines: SLBMs, or submarine-launched ballistic missiles. While six out of the world's seven nations operate these using nuclear submarines, South Korea—the seventh—only managed to accomplish this using diesel. This is not merely a matter of technology; it is an event that shatters common sense. There are four clues inside the submarine Dosan An Chang-ho. They are a second heart that does not use oxygen, a six-shot revolver carrying six missiles on the back, a titanium spine capable of withstanding 41 atmospheres of pressure, and invisible skin that absorbs enemy sound waves. Excluding perpetual motion—one of the core capabilities of a nuclear submarine—they have implemented the remaining three using diesel. When all these clues come together, the true answer to why South Korea went out of its way to achieve this finally emerges. It is a second-strike deterrent, a bridge laid in advance for a non-nuclear nation to transition into the nuclear age. On that bridge, 50 people have not surfaced even once for four weeks. We follow the clues to the real reason the ROKS Dosan An Changho is currently crossing the 14,000km Pacific Ocean to Canada, the real-world demonstration of the 60 trillion won bidding war, and the stories of the people living inside.
