I've just watched this interesting new video about the F-35 Block 4:[MEDIA=youtube]n3U6jr1rX5c[/MEDIA]Now given that there are so many software, hardware, propulsion and structural changes wouldn't this merit new series letters, that is:F-35A Block 4 => F-35DF-35B Block 4 => F-35EF-35C Block 4 => F-35FTo my amateur I think that such designation change is merited as the Block 4 design is a MASSIVE upgrade over the previous blocks.

Now given that there are so many software, hardware, propulsion and structural changes wouldn't this merit new series letters, that is:
F-35A Block 4 => F-35D
F-35B Block 4 => F-35E
F-35C Block 4 => F-35F
To my amateur I think that such designation change is merited as the Block 4 design is a MASSIVE upgrade over the previous blocks.
