NGAD funding. I previously described the funding curves for the NGAD program, often called the next gen fighter program or 6th gen fighter. It appeared NGAD was headed on a funding curve that mimicked the B-21. If that was the case, the NGAD aircraft would come out with an IOC between 2028 and 2030. However! The USAF budget request for the projected costs for FY20 were $1.35B. Instead, the ask for the FY20 is only $1B:
(page 27, section 3).
That would indicate the NGAD is being pushed back by a year at least. Given the funding profiles in other new-ish programs. Jane's reports NGAD is being rethought (article partially behind paywall):
There are two bits to consider. The first is the next gen jet engine (and probably what will be used on the NGAD aircraft) is being funded separately to the tune of $870M:
If that's considered part of the next gen fighter (a bit dubious, tbh) then the NGAD is humming along nicely. IIRC, the F-22 and F-35 funded their own engines. This is assuming the NGAD is actually going to use the AETP engine, of course.
Sadly, the shutdown seems to have wrecked havoc on the budget process, including merely getting the budget dox up where they are normally with the DTIC hasn't happened. So, it's hard to know what the USAF is thinking will be happening next with the NGAD: they put the next five years projected budget for each project in the budget ask. it's not set in stone, but is advisory for Congress. It also tells us layfolk what the USAF is thinking, generally, and helps with our projections as to when to expect.
Personally, I think we are seeing at least a one year delay.
However, there is a caveat: the B-21 program informed Congress one year they didn't need a few hundred million that year for the program. The projected IOC date of B-21 hasn't slid right though. The NGAD and B-21 programs are being managed by the Rapid Capabilities Office. It's possible the NGAD crew within the RCO has come to the conclusion some tech was trimmed from the program or didn't need as much development. Which case, this isn't a delay, but rather some risk was reduced by trimming some questionable tech.
Even so, I STILL I think we are seeing at least a one year delay.
YMMV.
