No. Russian Zircon is to deal with the next after nuclear strategic threat to Russia - US aircraft carrier groups. US pursue hypersonic weapons for different purpose - fast global much less than nuclear strike capability, ie. being able to strike any given target anywhere in like under half an hour. And thus not really much of hypersonic development in US - the cheap ballistic would do it better, especially with SpaceX driving down the cost of it. DOD is already excited that almost immediate delivery of 100ton, ie. instead of several C-130, payload by Starship anywhere in the world looks to be under $50M.
