The F-35 is more or less a Bombtruck for the USAF and NAVY and a replacement for the F-16, it`s still behind the frontline fighter F-22. The fact is, that this plane will be/would be the first line choice for the other countries.
Now we have to compare, US is developing a stealthy bombtruck and not a frontlinefighter <--- other nations need a frontline airplane and not a bombtruck.
Saab is developing a low cost alternative "Super" Grippen, enlarged fuel capacity, stronger engine and lower fuelconsumption, more sensors and bit more larger fuselage. Thinkin about a navalized version too. This plane is a nice low cost replacment for some F-16 fleets. And many countries wants to replace the F-16 with the 35.
A Rafale is a good choice to, Navalized version is standart, strong gear and fuselage. It will be interesting to see how this will go further.
