US ships in Asian Pacific,, Arabian Sea,, the Med,, if they engage against Iran they will be sitting ducks with no method of defense,, one hypersonic missile and they are toast...

Unfortunately the battlefield has changed and dominance has shifted,,, no longer is a large Navy a projection of power,, hypersonic missiles are the projection of power now...

The US/NATO was not successful in developing Hypersonic Missiles,,, their development program was cancelled in 2016 because they could not figure it out,, could not make it work,, so it was abandoned in favor of continued conventional methods...
