US Joint Chiefs Chairman Gen. Mark Milley said the Russian use of hypersonic weapons in Ukraine was not having “really significant or game-changing effects” during a House Appropriations Defense Subcommittee hearing.
“Other than the speed of the weapon, in terms of its effect on a given target, we are not seeing really significant or game-changing effects to date with the delivery of the small number of hypersonics that the Russians have used,” Milley said.
A senior US defense official said on Tuesday that Russia had launched between 10 and 12 hypersonic missiles against Ukraine so far.
Milley confirmed this was the first time hypersonic weapons had ever been used in combat, and he said that the Defense Department has analyzed each hypersonic strike, but added he could only elaborate on the details in a classified session.
US Defense Secretary Lloyd Austin said at the same hearing that he concurred with Milley, and he did not think that Russian President Putin’s use of hypersonics would “cause him to be willing to elevate to use a nuclear weapon.”
“I think he’s trying to create a specific effect with the use of that weapon,” said Austin, referring to hypersonics. “And as the chairman has pointed out, it moves at a speed that makes it very difficult to interdict. But it hasn’t been a game-changer.”
Earlier in the hearing, Austin said it was US President Joe Biden’s decision to share intelligence with US allies and partners in the lead-up to the Russian invasion of Ukraine.
“That created trust amongst our allies in a more meaningful way,” said Austin, “and that trust allowed us to create greater unity.”
Austin said that intelligence sharing was “a key element” in fostering that unity, which he hoped would continue.
