Yeah but the company associated with the Verpine are credited as building/designing the B-Wings as is Ackbar.
Not anymore! I always thought it was dumb to have Ackbar as the designer of the B-wing. Like they couldn't come up with another Mon Cal? He's a genius military tactician and engineer? That was the main problem with the EU. Too many characters were involved and did too many things.
<Sarcasm> Right because skilled engineers and ship designers can't possibly be good military commanders. </sarcasm>
Tarkin is a ship designer in both canon and Legends so I fail to see why people think Ackbar can't be both in both settings.
IRL when West Point started the top students of each class were sent to the engineering corp.
Also I don't know if this still stands but in the Cold War through the mid 90s US navy nuclear submarine officers took a test to see if they were qualified as chief engineers during or just after their first tour with failure meaning they had to transfer to another branch of the service.
If you really want me to I can go digging and give you the names of some successful Admirals involved in ship design from history.
