Technology is moving really fast these days. My fear is many weapons system that were supposed to be extremely effective when put into production will be all but mitigated by the time we build them in any number.
I'm really concerned with our reliance on 5th gen fighters and our stealth technology. I don't think any US pilot would care to fly a F22 or F35 over an area known to be operating Russian S400 or S500 SAM systems.
