Russia, China eclipse U.S. in hypersonic missiles, prompting fears

Russia and China are outpacing the United States in the development of super-fast missile technology, Pentagon officials and key lawmakers are warning.

Russia says it successfully tested a so-called hypersonic missile this month, while China tested a similar system last year expected to enter service soon.

“Right now, we’re helpless,” Jim Inhofe (R-Okla.), a senior member of the Senate Armed Services Committee, said in advocating for more investment in hypersonics, along with missile defense.
