USAF was not going to make the same mistake it did during the YF-22 and YF-23 competition by selecting the safer/common fighter in the YF-22 over the exotic one in the YF-23. USAF said LM version is evolutionary but it was building on its F-22 and F-35 while Boeing's F-47 is more ambitious and fresher approach. This was in Nov of 2023 when they said this so USAF already had a preference.
Boeing had decades to get ready for this competition after losing the F-35 competition and knew to think outside the box so they took a lot of their Bird of Prey design incorporating it into the F-47
This wowed the USAF and what also wowed USAF is that Boeing heavily invested in having the manufacturing plants ready which is really ballzy of them and could have broken their Phantom works division for good if USAF went with LM.
This why LRP can start in 2029.
Boeing came to play and was well prepared for this competition. It looks like LM kinda half a $$ed it not thinking outside the box likely too busy with F-35 program and Darkstar. I wouldn't be surprise if Boeng wins the Navy competition in a few months making it a clean sweep.
Makes me wonder if all this investment from Boeing into its Phantom works division may had a play in Boeing's civilian sector "issues."
