I have no clue about the powerpoint or its stealth properties, honestly I rarely read into anything anymore - I just happened to read the article from Janes Defense weekly which gave some promising info from tests done on it. Thats why I inquired about its landing capabilities on carriers - last time it was published
it said the Aircraft was unable to land on the carriers and the entire bellybutton end would have to be redone in order for it to work, something about it being to close to the landing gears.
It did mention its stealth capabilities, but I don't recall what was said.
Well, LM has been pushing this Fifth Generation meme for awhile. It is not accurate.
Also, side beam detection of the JSF is easy in every band. It was designed to defeat short ranged, mobile SAM radars. When they increased the size of the weapons bay they screwed up the lower quarter stealth of the airplane. Long range detection from the sides and rear in L-, S-, and X-Band (among others) is quite easy.
X- and S-Band radars are defeatable only about 14 degrees either side of the nose.
It has poor persistence, can't climb very high, has horrible kinematics, and its payload is anemic.
It just isn't a good airplane. At all.
