Tourist and the other froufroulating frolickers in F-35 fandom, read the bloody original.
New Gripen Aims For Low Cost, High Capability | AWIN content from Aviation Week
It's entirely clear from any reading of the text that the "flyaway" cost refers directly to the Swedish upgrade contract, which at the time was the only production contract had been signed. It's also clear that the "upgrade", even then, was one notch short of jacking up the serial number and building a new airplane underneath it. The story makes no attempt at the futile task of comparing that price directly with anything else.
Indeed, to compare the JAS 39 C-to-E mods to anything done to a Tornado, F-15 or F-16 bespeaks either missing data or a certain lack of honesty. Think F-102 to F-106. New engine, sensors, landing gear, core avionics and structural mid-section.
And Speedywheels brings up an important point, which is that the Swedish government (weeks after the story was published) announced a decision to build the JAS 39Es as all-new aircraft. I don't think that any effect on the contract has been announced.
