It's a great accomplishment, but it must also be stated that the FRP isn't for Block 4 F-35s, and multiple DoD staff have gone on the record that Block 4 will be a minimum for survivability, to clarify, that's "survivability" in high-threat environments.
War thinky types divide the "battle space" into zones of danger, and stealth platforms justify their cost by being able to penetrate highest threat areas. It's an idea that hasn't really been tested yet, not really, not since 1993. Hopefully we never find out.
Some of the Block 4 mods have been moved up, particularly the necessary avionics stuff, but some of the mods need rework for heat management and other deeper requirements.
