I don’t see the problem.

He confirms what I said… that the physical and design main-mission replacements were A-1>A-6 and A-3>A-5.

That one of the A-3/A-5 missions was later transferred to the A-6 changes nothing. I already mentioned that several of the EA-3/KA-3 missions were transferred to the EA-6B/KA-6K… this is just one more post-design mission shift.

We are saying basically the same thing… it is just that your earlier assertion was that the A-6 was designed to replace the A-3, which is not correct, and your friend confirms this.
