It is not so much a matter of not trusting/allowing them access to
technology as it is a matter of it being a spiral development effort. The
first US aircraft will be Block 1, followed by Block 2, then ultimately
Block 3; spiral development gets the aircraft into service earlier, albeit
without it having its ultimate capabilities realized. As more capabilities
are realized, they are incorporated into the production blocks. If it were
a
*trust* issue, why is the *US military* also going to have Block 1 and 2
aircraft serving in our own forces?

Eventually they'll get Block 3, whereas it looks like the RAAF never will.
That's the difference.
