Good stuff and agree on the idea of a constant cross flow program, variable to the needs of the AF.
As to the synch idea, airframe only. Said airframe would need to be fairly adaptable to be able to cover all those missions to a minimally satisfactorily level, particularly ADAIR and Chase Ship as I imagine the customers for those services want something more than a fat kid to fight against or keep up with them. I like Scorpion but it probably would need a hot rod version of the baseline jet to meet those missions in a useful way.
L-159/39NG would likely be the next best choice for an already existing platform considering total cost and capabilities required.
Shared fleet idea is not bad if the investment is/was there. Copy on ADAIR not being able to be stopping point, I think borrowing for ADAIR might be more palatable to Big Blue but they have already written a check for contract ADAIR, but one can advocate on BO...
The tyranny of aircraft fleet economics makes this a difficult idea to sell to the Bobs, I'm guessing if you could torture the numbers and get the costs down per tail/hour, you could argue for a 150-175 tail fleet for CTP, ADAIR, Light Attack, Chase Ship, Flight Based Training Platform, Test Platform, etc... figure you buy 160 L-159/39NGs at average $20 mil with all the goodies (radars, pods, sensors, etc) , program 500 hours per at $3,000 comes to some reasonable numbers for a multi-use, multi-mission platform.
I would say two problems, short term needs to the 11F/11A communities and long term needs to change the culture of the AF. If we want leaders and managers to not myopically focus on queep and realize the point of all of this is to generate airpower to perform X mission then we need more dudes to a experience a culture/execute a mission that probably focuses less on bullshit and more on delivering the mission / winning the fight.
I say probably as I have never been in a fighter/attack unit but having interacted with different fighter dudes at different times in different places, they did as a group display a less queepy mindset and I think that experience of single seat flying or at least often single seat flying in a dynamic mission or training environment causes some mindset shift. Particularly when you execute a mission where significant threat from the enemy exists and the pressure/expectation to perform is high as you are employing weapons against enemies often close or inter-twinned with friendlies, don't screw it up.
Not infatuated or a fighter groupie, I'm happily married to my heavy aircraft in a monogamous hetero-crew relationship but I think if there were a mechanism to let some reasonable number of dudes who tracked Heavy, FAIP, RPA, Bomber but wanted a fighter/attack jet to work hard, prove their mettle, meet a legit requirement and then serve in a tactically minded flying community (training or operational), I believe it would pay dividends in morale, retention and cultural renewal in some parts of the Air Force.
Don't doubt your point about retention of dudes who tracked fighters right out of the gate from SUPT but I see this idea as the one of many simultaneous efforts to return the AF to course.
Airplane porn just because...
