As complex and unproven the concept is....will not be a cheap exercise....akin to the V-22 and its history.
How expensive is an all things capable flying machine can be before it is too expensive when infrequent mission capabilities are thrown into the recipe that need not be there?
Expensive mean fewer bought.....then Mission Readiness rates matter.
If those few machines are evaluated as being ready for every task....as compared to being evaluated for the assigned tasks.....those few are going to suffer in that real world process.
But....if you only evaluate them for the assigned tasks at any moment you are ignoring the core problem that was built in at the inception of the program.
Ultimately the aircraft Gripe List means the aircraft is flying in a degraded capability thus all the Gucci Kit is not longer adding to the capability.
Sometimes well proven cheaper aircraft fit for most of the tasks might be a better way to go.
