In fairness, the Super Hornet Block III (I am not sure if we are getting this one) is a very capable aircraft chock full of the latest technology including a fairly low radar cross signature. It is not as stealthy as the F-35 and many not have its flying performance, but it is not bad. The larger question is whether the costs will be more or less the same. Assuming the F-35 comes in at a fly-away cost of $80M it would be in the ballpark of the Super Hornet. So do you buy 80% of the capability if the costs are the same?
