Yeah, I'm concerned 150 manned NGAD components also have we also forgot that they mentioned 2 separate NGAD platforms for the Pacific and Europe? it's very concerning Considering if we repeat the Raptors history meaning in Numbers and Budget Cuts NGAD is too important not to get the reasonable numbers the USAF needs to maintain Air Superiority in the future but I'm a-bit confused about the two separate NGAD platforms for different theaters...I think it's going to be like fighterjocks comment there will be fewer NGAD Manned Aircraft. But maybe it's just a lot of smoke in the air.I worry about numbers for the manned component. We've seen the tyranny of small numbers with the Raptor fleet and that's a fleet that's roughly 25% larger than 150. I really hope both services heed those lessons from the Raptor program and aim for a fleet roughly double that. Probably a pipe dream but even with a swarm of unmanned systems I doubt that 150 can meet maintenance and strategic objectives.
I think we can consider a separate European variant DOA after current events. The original goal was apparently to build a shorter ranged version for the theater, presumably for reducing cost or increasing maneuverability over the Pacific variant which appears to have a range requirement that heavily influences the design. But it's hard to picture a future where anything more than F-35s would be needed in Europe; there is no 5th gen competition and the USAF already has a combat coded 5th gen fighter for every 4+ gen fighter Russia has ever built (discounting other NATO F-35 operators). By the end of the decade there will be ~150 NATO F-35s on the Russian border (Poland, Finland, Norway).
