That’s before you add in that it won’t benefit from the proposed conformal tanks etc being looked at by LM for the F-35A.
Is that confirmed? I haven't seen any official announcement that the CFTs are for the A only. On the same subject, do we know if the drop tanks are for all variants (LM seem to be of the opinion that the B is plumbed and wired for them, despite claims on here that this was all stripped out some time ago to save weight).
