Speaking at a Defense Writers Group roundtable, Vice Chairman of the Joint Chiefs of Staff General John Hyten announced that China's hypersonic missile advancements are a field of concern.
"What you need to be worried about is that in the last five years, or maybe longer, the United States has done nine hypersonic missile tests, and in the same time the Chinese have done hundreds," Hyten stated, according to reports.
"Single digits versus hundreds is not a good place."
He did not elaborate on his anxieties.
Last week, it was announced that a rocket failure caused a delay in the U.S. military's test of its hypersonic weapons system.
ABC News reported that the military registered a test of its Army-Navy standard hypersonic glide body in Kodiak, Alaska, though it failed to launch.

In the meantime, intelligence sources have insisted that China conducted a second test of a suspected hypersonic orbital missile capable of carrying a nuclear warhead.
The new test is believed to have occurred on August 13 and involved a similar "hypersonic glide vehicle" to one launched into space onboard a Long March rocket in July, which was first reported earlier this week.

The new technology is supposed to have caught U.S. officials off guard, mainly as the system "defies the laws of physics" and seems superior to anything in the American arsenal.
Hyten announced the pace at which China is moving is "stunning."

"The pace they're moving and the trajectory they're on will surpass Russia and the United States if we don't do something to change it," he stated. "It will happen."

"I think we have to do something."
Hyten's anxieties mimicked those shown earlier this week by Gen. Mark Milley, chairman of the Joint's Chief of Staff.
Milley described China's suspected hypersonic weapons testing as "very concerning" in an interview with ‘The David Rubenstein Show’ on Bloomberg Television.

"I don't know if it's quite a Sputnik moment, but I think it's very close to that," he continued, referencing when the Soviet Union beat America to space in 1957 with its Sputnik satellite. "It has all of our attention."
Milley further warned the new missile systems are only one of many things the U.S. must be concerned about as the Chinese military expands.

"The Chinese military capabilities are much greater than that. They're expanding rapidly in space, in cyber, and in the traditional domains of land, sea and air," he told Bloomberg. "We're in one of the most significant changes in what I call the 'character of war.'"
