Didn't the UK back out of two of their E-7s anyway?Funding for the first prototype is included in the FY-23. The 23 NDAA is likely months away and could go into early 2023. Much like the F-15EX prototypes, I'm sure Boeing and NG could (and possibly would) front the suppliers to begin work on this and deliver months ahead of original delivery dates. They are also going through the UK order so that could explain the AF giving them more time.
