Feel free to prove it, conclusively without resorting to speculation.
I'd like to see if it's possible, although I doubt it.
In both cases supposition is involved, as no detailed records have yet been published by the show's producers.
No published records on what constitued a Megaroad fleet after Megaroad 01, whether new fold systems were installed on the SDF-1 (however logically they should have, but nothing documented), if the Macross ever left the lake after 2040, if it even left the Sol solar system, if more SDF class battleships were built, etc...
Nothing, nadda, blank pages in the chronology and official records as we have them (as Kawamori left it).
