When people think about how a city is destroyed in a nuclear war, they invariably question where the missile or bomb will have come from.
One option, the oldest, is strategic bombers like the B-52. Another is from nuclear submarines. Recently, a Russian submarine that carried nuclear torpedoes was seen near the Arctic Circle. The third threat is intercontinental ballistic missiles that travel thousands of miles carrying multiple warheads. (This is what a nuclear war would do to the world.)
ICBMs are usually launched from inside the borders of the deploying countries. China’s DF-41 can travel 7,456 to 9,321 miles, the greatest distance of any long-range missile, according to Arms Control Association, an organization that promotes effective arms control policies. Russia and the U.S. also have extremely long-range missiles.
For comparison purposes, the longest commercial flight in the world is the Singapore Airlines route from New York City to Singapore, which covers 9,537 miles. People routinely have to fly 7,000 miles or more to reach several cities in Australia.
