The other objective to achieve a production cost equal to or less than the current soring F-35, by doing this on their own, vs constantly having government oversight causing further delays and cost over runs. Just like the S-97 development. Basically, they're just letting the engineers go at it, and have fun with it. Kind of like the way the A-10 came about. They just let engineers build something, based on what the combat specs were, and the top brass and politicians just stayed out of it.
As a result, we all know how the A-10 turned out. The friggin' Ruskies hated that God aweful thing back in the 80's.
Lockheed returning to the system in which they perform best. The F-117 for example was under budget when there was little government oversight present.
