but in practice we are not really seeing it.
First, we are off topic as this is a news thread and may or may not even belong under the F47 speculation thread, but..
These timelines are true, but to me every program here began before there was any real urgency being felt by the government. By the time the urgency was being felt, it was too late to make any significant changes.
I always think about it relative to when US-China relations really began to sour, which was right around the time the LRS-B was announced. LRS-B began too early after this to really make a difference. F-35 was eating bricks by the truck full already at this point. The T7 was a trainer, not terribly urgent program either.
Momentum really started to build beginning in 2018 - start of the war in ukraine, when more and more think tanks, analysis, media and the likes began to recognize the grave threats China was fielding. The 2018 national defense strategy really began to recognize china as the pacing threat. Following those reports, in my own memory, more and more weapon programs were started and fast tracked (hypersonic missiles beginning with the HAWC prototype, AIM260, AIM174, CCAs). When Ukraine happened, thats when I started to hear more and more about speed mass and affordability. 2019 was when the USMC decided to begin reforms back to its roots. 2020 ish I began to hear about agile combat deployment and what not.
So whether its program speed, shipbuilding, sentinel or any other egregious problem right now, all I can say is that things really only just got started and the urgency to action feedback loop takes a couple years to get underway let alone figuring out exactly what you need and fielding those things. Add to that the sheer institutional momentum of shifting an entire nation as well as within branches (right before WWI and WWII, iirc people like Marshall and Spruance replaced a huge number of officers with people they knew could lead). People weren't being replaced as far as I know, but institutional changes were beginning to be implemented early 2020.
Though it would please me greatly if congress stops talking big talk and walk the walk too by giving me back my 5% defense spending, the manpower and supply chain problems wont necessarily be able to take full advantage immediately anyway as the solutions to these problems need at least a decade before getting better.
At least this is my impression.
