"맞는 순간까지 표적은 몰라요" 단 한 척이 미 항모전단 40척을 침몰시킨 과학

Until the moment it was struck, the target didn't even know it was going to be hit. A small 1,200-ton diesel submarine entered the middle of a U.S. carrier strike group of 30 ships. It was never detected and fired over 40 simulated torpedoes. The U.S. media called this "one shot, one kill, one sync." However, this submarine was built by a country that started 30 years later than North Korea. This video answers three questions at once. First, why does a submarine remain unaware of its target until the moment it is struck? (Underwater physics where light dies and only sound lives) Second, how did the country that started 30 years behind acquire that technology? (People who learned the blueprints by covering their windows with blankets) Third, why did a large and expensive nuclear-powered fleet lose to a small diesel submarine? (The truth about RIMPAC 2004) The weapon that Churchill called "the most difficult fear to overcome." A country acknowledged by the Commander of the U.S. Pacific Submarine Command as having "achieved in 10 years what other countries took 100 years to accomplish." That is Korea. Science is the entrance, and the reversal is the main body. If you read to the end, you will want to leave a comment. ** ## Chapter 00:00 A 12,000-Ton Warship Split in Two by a Single Submarine Shot — Why Don't the Target Know? 01:30 The Underwater World Is Blind, Ruled by Ears — The Physics of Light vs. Sound 04:00 Three Organs: The Submarine's Ears (Sonar), Silence (Stealth), and Lungs (AIP) 08:30 A Start 30 Years Later Than North Korea — Why We Started from Scratch 11:00 "Please Sell Just One Ship" — The Birth of the Jang Bogo 13:00 Skills Learned by Covering Windows with Blankets — A Human Drama 15:00 RIMPAC 2004 — The Day Little David Sinked a US Carrier Strike Group 17:30 Localization Rate 33% → 82%, Transition to an Exporting Nation — Our Submarines Today 19:00 The Next Shot: Nuclear-Powered Jang Bogo N — The Next Reversal of 30 Years at the Bottom
