This is completely wrong, though. It's cheaper to build an F-35 than it is to build a Eurofighter, Rafale or Gripen, which are significantly older and less capable platforms. And not even "a little" cheaper - quite a bit cheaper. Economies of scale are real

After reading your comment I did read up on the Gripen. Seems very interesting. Procurement is about the same as the F-35 but the running costs are about 1/4 so over its expected lifetime it'll be considerably cheaper. On the procurement front though Saab seems to offer factory set up as part of the deal, so you make back some of the cost into your economy. Being able to build and maintain them yourself seems like a big plus.

Capability wise the gap isn't as large as I thought either. The latest Gripen-E has similar radar, possibly better software, and they can be kitted out to fire the same air to air weapons. What they don't have is a stealthy airframe and they aren't designed for some of the same mission profiles. If you're a country that doesn't make your own aircraft then having access to both, or just the Gripen for interceptors would make some sense.
