I think it's important who's making the statement. He's very much a biased party.
True but Hegseth or Trump, among others, could overrule him if they felt it was critical. So tells me they must agree to some extent (Trump not being an SME in these matters would defer to Hegseth’s position).
I know if I was President atm, and my chief procurement officer expressed such concerns, I’d fix them asap and, given both Boeing and NG both expressed confidence they can build the Navy NGAD while the F47 is going together, I’d make them show me they can do so. If I am satisfied with what each had to show/tell, I direct the Navy to complete downselect and award the EMD contract to their preferred choice.
If a selection hasn’t been made yet, they would have to come up with the mother of all justifications as to why not and sell me like they’ve never sold anyone on anything before to get me to allow more time.
I don’t see China holding back or pausing anything. No one over there seems to have “industrial base” concerns, at least any I have heard.
How does the F18 SH and/or Growler fare in a live engagement against a J20 (or four-ship vs four ship)?
Maybe the Navy has reason to believe the Rhino/Growler pilots would not be out matched. Or they simply figure all such situations would be handled by the F35C or USMC F35B and that’s more than enough for the next 10 years if push comes to shove…
