China's reported hypersonic missile test "an important surprise" for U.S.
BY RAMY INOCENCIO

Hong Kong — China is shooting down a report claiming it successfully
tested an advanced weapon known as a hypersonic missile. Beijing
described the launch as a "routine" test of a reusable space vehicle,
but Washington insiders say that if China really has successfully tested
hypersonic missile technology, the U.S. is simply not ready to contend
with the threat that poses.

Hypersonic rockets travel at least five times the speed of sound, and
they can fly much lower to the ground than conventional ballistic
missiles. That makes them much harder to trace, and thus much harder to
stop.

The last time the world saw China's arsenal of hypersonic missiles was
in 2019, as the Communist Party put its latest technology on display in
a huge military parade through central Beijing's Tiananmen Square.

The report in The Financial Times over the weekend claimed that China
launched a hypersonic missile over the summer, which it said circled the
globe before landing about 25 miles from its intended target.

Retired U.S. Admiral James "Sandy" Winnefeld, a former vice chairman of
the Joint Chiefs of Staff, called the apparent Chinese test "an
important surprise" for American, "because it demonstrates the
capability to have a very long-reach hypersonic weapon that could cause
a lot of damage without us being able to do anything about it."

On Monday, Beijing responded to the newspaper report, with Foreign
Ministry spokesman Zhao Lijian telling reporters it was "not a missile"
but rather "a space vehicle" used in a "routine test" as China develops
technology to lower the cost of future space travel.

But China has continued to build-up its military capabilities. The
country already boasts the world's largest standing military force, and
it hasn't been shy about throwing that weight around — the record 149
military flight incursions into Taiwan's air defense zone this month
being the most recent example.

In a "60 Minutes" interview over the weekend, Anderson Cooper asked
former U.S. Secretary of Defense Robert Gates about China's military
expansion, and the potential for a Chinese invasion of democratically
governed Taiwan.

"There are two strategies that we need to focus on," Gates told Cooper.
"One is deterrence — strengthening our own military presence in the
region, and the second piece of the strategy is to strengthen Taiwan's
ability to defend itself."

Only the top levels of China's leadership may know if the country really
carried out a successful test flight of a hypersonic missile — or "space
vehicle."

The U.S. and Russia have also been testing their own hypersonics, but if
the Financial Times report is accurate, that would imply that China has
taken the lead in the hypersonic arms race.

Hypersonic missiles go back to the 1950s.
ICBMs which are boosted at about 15,000 mph.

You don't seem to understand the difference between the two. Yes, ballistic missiles do travel at hypersonic (and faster) speeds. But ballistic missiles travel in a high, very predictable arc on the way to the target. The new touted hypersonic missiles are not ballistic, they travel in much lower, flatter parabolas and have the ability to maneuver while doing so, especially in the terminal phase. I haven't seen much on exactly how they are guided to a target. One would think that the plasma sheath generated at those speeds would make sensing difficult but obviously there are solutions.

I do understand the difference, but I just don't see much feasibility in trying the maneuver and travel very far
in the atmosphere at X-15 like speeds.
