These are nothing like the Osprey. The Osprey is way more complex. If one of the engines goes out on the Osprey, there is linkage that will allow the remaining engine to continue to power both rotors. Nevermind the mission profiles are completely different.

How long did the SR-71 take to make it into service? How long did the F-22 or F-35 take? None of those answers have anything to do with the other.

There's a pretty direct correlation between number of stakeholders who need to not object and procurement time.

One trick pony spy plane go fast took no time at all.

F15 but stealth took years

F35 cluster fuck took decades.

The correlation you're looking for is number of requirements, not number of stakeholders. They can be related in joint programs but aren't always.

Eh, yes and no. They tend to have a pretty strong relationship to each other. But we've all been party to swiss army knife projects that get shit all over by stakeholders because they don't agree about what the right balance of "shitty at everything" ought to be.
