If I´m not mistaking, the AF wants to award an EMD-contract next year for a very, very expensive air-dominance 'platform' that comes with a lot of whistles & bells, and as I have read/understood during the past months, one that will already incorporate as much as possible all of the desired technologies & subsystems at the time the EMD-contract decision has to be made, to avoid (another) prolonged and more complicated development later on. I would assume the AF is taking a similar path with the NGAD-platform as with the B-21; to be able to move from developmental aircraft to production-aircraft as swiftly as possible.
I'm inclined to believe something is going on that is different than in the past. Vago Mauradian and JJ Gertler has mentioned 2028 as when NGAD will either be operational or flying. Air and Space Magazine has used 2030, not the 2030s. The only information we have to go off of is what officials or journalists with sources have unveiled.
Roper's comments were followed by others:
Lieutenant General Clinton Hinote, the AF’s Deputy Chief of Staff for Strategy, Integration and Requirements, has mentioned that he has taken legislators to view the “aircraft" and they have been impressed. Lieutenant General Richard Moore, Deputy Chief of Staff for Plans and Programs more recently has noted that “NGAD is not a powerpoint aircraft. It is real and has flown.” At the very least, I don't think it would be unreasonable to assume that the demonstrators are full scale demonstrators that at least resemble the production aircraft to some degree.
The AF has spent a lot of money in the Technology Maturation and Risk Reduction phase. What has that got them? At least three "demonstrators?" Similar to the YF-22/YF-23 and the X-35/X-32? Or something more mature in development?
With the engine program, the AF has expressed a desire to carry the Pratt and GE to prototyping before an award. The AF could be following the same path with the airframe, and possibly the mission systems for that matter. John Sneden from GE expects testing in 2024-25 and a down select in 2026. Funding for NGAP begins to decline after FY24 and ends after FY27, pointing to production?
If there is a high degree of maturation in the designs I could see that a contractor could roll out the first test article by 2028. The engine should be ready by then. But it would be much more difficult for NGAD to become operational by 2028. How long would testing take before production aircraft were rolled out? 2 years? More?
If the AF can pull this off then they are clearly far a head of the other services in vision and execution.
