Just out of curiosity, are the aircraft themselves sufficiently classified that we couldn't sell one to the Israelis? Obviously, their payloads are (Bunker Busters, etc.) so, if we ever did it, we'd sell only the aircraft without the payload....
Let's, for the sake of discussion, take classification out of the mix.
I spent close to 17 years of my USAF career in the B-1B program.
The logistics of giving them an airframe or two isn't as simple as buying or renting a car for a trip.
There is a giant footprint of training, support and maintenance that has to be accounted for.
You don't just send a couple of guys over with the aircraft and tell the RSPs to have fun and try not to break it.
The maintenance support alone is huge with the number of crew chiefs, avionics specialists, powerplant, hydraulics, electrical, fuel systems, egress systems, flight control, and a host of other specialized maintainers.
Then you get to add in ground support equipment, fuel delivery, in hangar maintenance, phase inspections, depot level maintenance too.
Oh, I forgot, the entire purpose of them borrowing a couple of Bones is Armament.
Now you need equipment, load crews, armament storage and delivery.
Did I even touch on spare parts?
Nope. That's an entirely new group of people, storage, delivery and logistics.
On top of all of that, the support equipment and personnel have to have a place to work, eat and sleep (yes, in that order).
Bomber aircraft don't fit into fighter ground operations and ground space.
If you have any doubt about that, ask the folks at NAS Fallon.
Lastly, and most important are the actual personnel responsible for flying and maintaining the aircraft.
The time it takes to qualify a pilot, co-pilot, OSO and DSO aren't quick.
Qualifying maintainers takes even longer. On most airframes, qualification from the trainee level to basic qualification is 12-15 months. On the Bone it was 18-20 months. And that wasn't due to a lack of a good training program.
Tech schools, designed to get the new recruit to a trainee level are anywhere from 2 months to 11 months. That also has to be factored in.
Let's not even factor in Technician level (or the old Master Technician) levels of understanding and qualification.
Who would be responsible for their initial and upgrade training? The US?
So I ask: if we handed over a couple of Bones to them, how long do you think it would take to get them up and going?
I suppose we'd also have to build the big bunker buster bombs for them...
