Kratos will at least build some. I have no idea whether Boom plans to then take over production themselves (I can not imagine that actually happening).

>I mean, the manufacturer usually cares in the sense that the manufacturing and operating costs inform the purchase.

Sure, but Boom never promised what exactly their partners will be doing. Unless they are pushing some serious requirements on Kratos, beyond "the renewable fuel should also work", Kratos doesn't need to really care.
