Re: Sensor fusion?
The F-35 is far from the only fighter to combine sensor data to present the data in an integrated fashion to the pilot. Even the cheapest western fighter on the market, the Saab Gripen, does that in its new version.
"Sensor Fusion" is just part of LM's branding and marketing, along with "5th Generation" (which the F-35 isn't, if you go by the original Pentagon definition of what a 5th generation fighter would be).
