The U.S. Navy could be on the verge of changing the way that America fights wars.
With what they’re calling a rail gun.
The rail gun — propelled by an electromagnetic pulse and striking its targets at seven times the speed of sound — introduces what could prove to be a smaller, cheaper, but more destructive weapon that can replace the large, expensive missiles currently stocked on Navy ships.
North Korean state media warned on Tuesday of a nuclear attack on the United States at any sign of American aggression, as a U.S. Navy strike group steamed toward the western Pacific – a force U.S. President Donald Trump described as an “armada”.
Trump, who has urged China to do more to rein in its impoverished ally and neighbor, said in a tweet that North Korea was “looking for trouble” and the United States would “solve the problem” with or without Beijing’s help.
U.S. Defense Secretary Jim Mattis said the deployment was not tied to a specific event but a matter of prudence.
“She is just on her way up there because that is where we thought it was most prudent to have her at this time,” he said at a Pentagon news conference.
White House spokesman Sean Spicer said Trump had put North Korea “clearly on notice” that he would not tolerate certain actions but dismissed Pyongyang’s nuclear attack threat.
“I think there is no evidence that North Korea has that capability at this time,” he said. “Threatening something that you don’t have the capability of isn’t really a threat.”
