US Air Force jet engine manufacturing plagued by 'significant challenges'

• there was a recent article detailing why jet engines are so hard to do, and that the US was one of the few countrys that maintained the very complex and precise layered knowledge and manufacturing base to make the hot section blades and the arcane methods to keep even those ultra tough and durrable parts from melting or breaking. To put it into perspective, every last thing in your home or business would be burnt and destroyed very quickly if exposed to the conditions inside a modern jet engine, including titainium and ceramics. From my perspective I can see how under current management conditions it would be easy, very very easy, for some bro to wreck decades of acumulated knowledge and practice and never even know, and his "superiors" to never know, just that there is now a problem with something™. And they also dont know that in mechanical engineering of aircraft the first law or aviation is that everything effects everything else , which requires some things to operate at there limits, meaning that changes or substitutions will fail the whole aircraft, or create havock for maintenance, etc, etc, etc. No Bros, bro.

• I know nothing. But when I see headlines like this, and our dwindling missile stockpiles, and the fact that we have moved all carriers away from Asia, and the many other worrying things, I have to ask - are we about to get attacked? We seem rather weak right now.

• > are we about to get attacked?

  Nah.

  Not because we aren't relatively weak right now (because we are), but because there isn't another world power that has the motive and desire to attack us at this time despite our being weak.

  All of the US-Sino saber rattling comes from the US, not China.

  China is more than happy to just sit back and watch the US empire fall from the inside out entirely through the incompetence of our own leadership.

• far simpler to watch US self-destruct than to attack

• No, but private conversations between China and Taiwan right now are probably… tense.

  Korea as well this week.

• Our nuclear subs alone are a significant deterrent (as long as people think you'll use them).

• The US is not about to be attacked. But your allies are getting sick of your bullying and hypocrisy. Without allies you won't keep your overseas bases, and without those you cease to be able to project power and maintain global dominance.

• I suspect but cannot prove that a lot of the issues the US is experiencing right now exerting itself around the globe, such as lack of regional logistics ports and long supply lines and less enthusiasm from allies to join in, would apply in spades to anyone who decided to have a serious pop at the continental USA (barring globe-spanning nuclear missiles, but nobody wants to start that war right now).

  Looking like a big man in your near waters, no more than a few days away from a home port, is one achievement (and it is an achievement - many nations can't do this). Sustaining a war on the other side of a serious ocean or two is a game very few countries in the world can manage right now.

  The US would look extraordinarily strong to anyone bringing a war to the US.

• The US mainland won't get attacked but places the US wants to protect like Israel already are.

• Those questions at the end of the article sounds like Gov has no idea what the problem(s) even are

• As practically anyone who has worked in even the smallest organization knows, much of the success depends on doing boring things well, efficiently and predictably. The U.S. Federal government has lost the interest and depth of competence to carry out the boring stuff, while focusing much of its attention on pointless vanity projects. It’s no surprise that logistics is suffering when the top leadership has zero experience (or even interest) in it.
