The Pentagon has reportedly been testing the hypersonic missiles, although the weapon’s programs suffered a setback on Thursday when a booster carrying one of the rockets failed. The hypersonic glide vehicles the US could strike China with will get launched from a rocket in the upper atmosphere before gliding to a target at speeds of more than five times the speed of sound, or about 3,853 miles (6,200 kilometers) per hour.
In tests on Wednesday, the US Navy and Army tested hypersonic weapon component prototypes which successfully “demonstrated advanced hypersonic technologies, capabilities, and prototype systems in a realistic operating environment”, the Pentagon said in a statement.
President Biden said at a town hall event organised by CNN: “China, Russia and the rest of the world knows we’re the most powerful military in the history of the world.”
He reassured Taiwan that they don’t have to “worry about whether they’re going to be more powerful.”
Mr Biden’s comments come after soaring tensions in the region erupted on the Taiwan Strait, with the Chinese military flying huge numbers of planes close to Taiwanese air space and building air bases nearby.
The international community fears this signals a planned attack on the Island – as China seeks to exert its dominance in the South China Sea.
In a show of support, Washington has made security pact with Taiwan to provide it with military hardware and technology.
But it has previously chosen not to confirm whether it would send troops to defend the island, which has a policy of “strategic ambiguity”.
Global Times, a state-run newspaper in China, published in an article last week: “The island’s society must be warned that they better not believe the ‘rock solid’ promise of the US, because Washington will never fight to the death with the Chinese mainland for the island’s secession.
“All it is doing now is playing geopolitical tricks.”
And they sent a chilling threat, writing that China is ready to “smash the US’ so-called ‘rock solid’ commitment with its iron will”.
