Video Description

Japan put a railgun on a real warship. The U.S. Navy built it first but chose to stop. It sounds like a simple story of success and failure. But the real question is deeper. Why did the same technology lead to two very different decisions? We keep it simple. What railguns actually do, how far Japan has pushed the technology, why the U.S. Navy paused its program, and what this tells us about modern naval warfare. In this video: HOW RAILGUNS WORK: Why electromagnetic launch changes speed, range, and cost per shot JAPAN’S APPROACH: What makes Japan’s railgun practical and what limits remain THE U.S. DECISION: Why America quit despite leading the technology POWER & DURABILITY: The real engineering problems behind railguns STRATEGIC CONTEXT: Why railguns fit Japan’s defense needs better than America’s DETERRENCE, NOT HYPE: What railguns can and cannot change in warfare TIMESTAMPS 00:00 Why Railguns Matter Now 01:42 How Railguns Differ from Conventional Guns 04:08 Japan’s Railgun Program Explained 07:50 Why the U.S. Navy Stepped Back 14:34 Strategy, Deterrence, and What Comes Next CREDITS:"USS Zumwalt (DDG-1000)" (https://skfb.ly/6RqpB) by Yakudami is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/by/4.0/). #wartechexplained #japanRailgun #militaryanalysis
