Russia's Avangard hypersonic system

The US military has admitted that the United States is lagging behind Russia and China when it comes to hypersonic weapons development, according to The Hill.

"Right now we are helpless," Republican US Senator James Inhofe, who sits on the Armed Services Committee, was quoted by The Hill as saying.

He was echoed by Thomas Karako from the Center for Strategic and International Studies, a think tank, who agreed that Russia and China are outpacing the United States in terms of developing "super-fast missile technology."

"And the reason is the US hasn't been doing anything near the same pace, both in terms of developing our own capabilities, but also failing to develop sensors and shooters necessary to shoot down theirs," he underscored.

Earlier, General John Hyten, head of US Strategic Command, admitted during a Senate Armed Services Committee meeting that the US missile shield is unable to contain hypersonic weapons.

"We don't have any defense that could deny the employment of such a weapon against us, so our response would be our deterrent force, which would be the triad and the nuclear capabilities that we have to respond to such a threat," Hyten said.
