>But then of course the aircraft got saddled with requirements from three different branches of the military at once which made it extremely difficult to design and build and thus very very expensive.
Sounds rather like the Space Transportation System. During design, it went from a compact inexpensive passenger shuttle with modest payload capability, to a complete pig of a ship. And all because the Air Force contributed cash on the condition that it be capable of classified high-payload-pass missions to polar orbits.
It is nothing short of a tragedy that fully-reusable compact shuttles with flyback boosters (like the Rockwell P333) lost out to the disposable-booster design that was eventually built.
An extremely important part of project management is the ability to say "no", even if the customer is bringing extra money to the table. Extra requirements have a way of increasing costs in an exponential way and it's very easy to lose sight of your original goal.
Of course this is a problem when you have Congress breathing down your neck and looking for any excuse to cut your program. One big advantage of skunk works projects is that they keep you firewalled off from idea men.
