 [Business Insider] The 107-country Outer Space Treaty signed in 1967 prohibits nuclear, biological, or chemical weapons from being placed or used from Earth's orbit. What they didn't count on was the US Air Force's most simple weapon ever: a tungsten rod that could hit a city with the explosive power of an intercontinental ballistic missile.
During the Vietnam War, the US used what it called "Lazy Dog" bombs. These were simply solid steel pieces, less than 2 inches long, fitted with fins. There was no explosive — they were simply dropped by the hundreds from planes flying above Vietnam.
Lazy Dog projectiles (aka "kinetic bombardment") could reach speeds of up to 500 mph as they fell to the ground and could penetrate 9 inches of concrete after being dropped from as little as 3,000 feet. |
