Russia conducted a test of a revolutionary nuclear-capable drone submarine that poses a major strategic threat to U.S. ports and harbors.
U.S. intelligence agencies detected the test of the unmanned underwater vehicle, code-named Kanyon by the Pentagon, during its launch from a Sarov-class submarine on Nov. 27, said Pentagon officials familiar with reports of the test.
No details were available about the location or results of the test.
Pentagon spokesman Capt. Jeff Davis declined to comment. “We closely monitor Russian underwater military developments, but we will not comment specifically about them,” Davis said.
