@cbsnews: The United States has confirmed for the first time that it has deployed weapons in space, prompting separate warnings from China and Russia. Air Force Secretary Troy Meink told the Air and Space Cyber Conference in Maryland this week that the U.S. has fielded "on-orbit space control weapons capable of defending the Joint Force against hostile adversary action." Meink did not detail what the weapons were or how they work. China on Tuesday warned against turning outer space into a "battlefield" and Russia said it must be "free from any weapon" after the United States confirmed that it has arms deployed in orbit above the Earth. #space #military #worldnews #airforce
