We find ourselves with this game as a result of some some weird notion of keeping the culture surrounding the legendary jammers current in an age of free-to-play games.
The price-tag of a legacy fighter may appear to be lower, but if it is less likely to survive combat, or its survival depends on support from electronic jammers and other helpers that a stealthy fighter does not need, then in the end the plane with the higher price-tag may turn out to be cheaper.
