You said the capability has to justify the cost and that we have "wasted" our hornets and harriers over the past 15 years on things less expensive platforms could have done.Straw man argument much?
That applies to pretty much every platform in the DoD inventory that can drop a bomb except maybe B-2's.
No one thought it wanted to admit we would be doing this for 15 years. Getting rid of our Gucci toys because we aren't using them as designed isn't a good plan if you may need them in the future.
Do you not use something just because it's overkill? Did it make sense to fly a B-1 from Qatar to Afghanistan every day with 20+ bombs and the tankers necessary for them to drill expensive holes in the sky? No. But everyone wants to be relevant, and getting rid of them doesn't make a lots of sense either.
