Boeing's goal at programme launch in March 2009 was to reduce the RCS signature to a level equivalent with the frontal-aspect stealth of the "international release version" of the F-35.

Did I hear correctly? The export version of the F-35, the one the likes of the UK & most of Europe, Isreal and Australia are considering spending billions of dollars on is going to have its best face (frontal RCS) no better than a souped up, botoxed, 1960's, fundamentaly non-stealth fighter! Now thats either a really good job that Boeing have managed with the F-15 or we are seriously ******!
Say Osbourne, I got a budget cut you might be interested in, the F-35.
