Is there anything written in that article that specifically states that this is the first-ever-on-earth swear-to-god United States of America military hyper sonic vehicle like going back to maybe 1960? Why on earth do you guys vice jaw your own scrotum with such force is beyond sensible.
We are never behind any nation in any military technology... ever!
Not necessarily true, though. We're not necessarily more advanced than 100% of the nations on earth with 100% of weapons systems.
Are we more capable of developing pretty much any weapon we want? Yeah, I'd think so, but in reality, we develop weapons based on the threats we prioritize, and sometimes we're slow to catch up to those threats. The U.S. has, for the past 15-20 years, been focusing on winning wars against insurgency groups like Al Qaida and the like. We've probably become as advanced as any nation on the planet in terms of fighting house to house, which is a capability Russia's military would love to have right now.
But Russia and China prioritized their missile systems because they knew that they're at a disadvantage relative to the U.S. Russia's missiles travel farther than ours. They also have multiple reentry warheads with the capability of evading anti-missile defense systems with the use of decoys. Now could the U.S. develop these technologies within 6-18 months? Absolutely, but we're caught off guard, and the reason is, Russia made it a priority to invest in their missile systems.
To be clear, Russia's not going to launch a first strike on us anytime soon because a) we'd still detect the incoming missiles in time to launch our Minutemen missiles, and b) we have nuclear subs that are hard to detect. We could decapitate Russia with an attack on Moscow and St Petersburg.
Truthffully, I think Russia's hypersonics are more a threat to European cities than the U.S.
