The Coming Hypersonic Nuclear Arms Race: Daniel 7

US confirms China’s hypersonic missile test with concern, says it’s ‘close to a Sputnik moment’

The top US military officer, General Mark Milley, has provided the first official US confirmation of a Chinese hypersonic weapons test that military experts say appears to show Beijing’s pursuit of an Earth-orbiting system designed to evade American nuclear missile defences.

Key points:

  • Hypersonics move at speeds of more than five times the speed of sound, or about 6,200 kph
  • Sources say the test involved a weapon that first orbited the earth, something called ‘fractional orbital bombardment’
  • China has denied the claims, saying what it tested was a space vehicle

The Pentagon has been at pains to avoid direct confirmation of the Chinese test this summer, first reported by the Financial Times, even as President Joe Biden and other officials have expressed general concerns about Chinese hypersonic weapons development.

But General Milley explicitly confirmed a test and said that it was “very close” to a Sputnik moment – referring to Russia’s 1957 launch of the first man-made satellite, which put Moscow ahead in the Cold War-era space race.

“What we saw was a very significant event of a test of a hypersonic weapon system. And it is very concerning,” Mr Milley, chairman of the Joint Chiefs of Staff, told Bloomberg television, in an interview aired on Wednesday.

Nuclear arms experts said China’s weapons test appeared to be designed to evade US defences in two ways. 

First, hypersonics move at speeds of more than five times the speed of sound, or about 6,200 kph, making them harder to detect and intercept.

Second, sources tell Reuters that the United States believes China’s test involved a weapon that first orbited the Earth.

That’s something military experts said was a Cold War concept known as “fractional orbital bombardment.”Is Asia’s space race also an arms race?The pool of countries deploying huge amounts of cash as part of a new space race is growing larger. But experts fear this could be a sign of a new arms race, too.Read more

Last month, Air Force Secretary Frank Kendall alluded to his concerns about such a system, telling reporters about a weapon that would go into an orbit and then descend on a target.

“If you use that kind of an approach, you don’t have to use a traditional ICBM trajectory – which is directly from the point of launch to the point of impact,” he said.

“It’s a way to avoid defences and missile warning systems.”

Fractional orbital bombardment would also be a way for China to avoid US missile defences in Alaska, which are designed to combat a limited number of weapons from a country like North Korea.

Jeffrey Lewis at the Middlebury Institute of International Studies summed up fractional orbital bombardment this way:

“The simplest way to think about China’s orbital bombardment system is to imagine a space shuttle, put a nuclear weapon into the cargo bay, and forget about the landing gear,” Mr Lewis said.

He said the difference was that the Chinese re-entry system was a glider.

It said it had carried out a routine test in July, but added: “It was not a missile, it was a space vehicle.”

US defences are not capable of combating a large-scale attack from China or Russia, which could overwhelm the system. 

But the open US pursuit of more and more advanced missile defences has led Moscow and Beijing to examine ways to defeat them, experts said, including hypersonics and, apparently, fractional orbital bombardment.

The United States and Russia have both tested hypersonic weapons.
