Well it's a bizarre situation. Boeing has clearly demonstrated the ability to rapidly design, build and fly sixth gen airframes and if NGAD is anything like Raider, will have lifted as many subsystems as possible from other platforms except for a few key subsystems. One of these subsystems is of course XA102/103. Putting aside (1) how a VCE might need unique interfaces with the rest of a sixth gen aircraft to maximize harnessing power generation and cooling capabilities of the third stream and (2) USAF and industry studies have linked maximizing the control effector promise of conformal fluidic nozzles to a VCE, unless MBSE and digital twins have some magical compressive effect on timelines, I can't see any F-47 flying with a production A102 until the upper end of the 2025-2029 range on that slide. I will let
@F119Doctor opine on the what the likely *realistic* timelines are for the two programs, now that DDR is behind them.
If the reality is that F-47 can fly its mission without VCE, which doesn't seem unreasonable, then I can see F-47 flying in 2027, which *should* allow time for Boeing's Advanced Combat Aircraft Center in St Louis to complete - currently the language is "by 2026" so putting that through the reality reinforcement field, means fall 2026 to me, which puts first flight off the line ~ late summer 2027.
