Having to do it according to the terms of their license doesn't make it a realistic goal. Three or four launches by 2026 would be more in line with the traditional pace of new launchers (and this doesn't account for Blue Origin's uniquely slow pace.)
Get your facts right. That’s Amazon, not Blue Origin. Amazon has booked flight with various launch providers, including SpaceX to meet their license’s requirement. It’s still a very aggressive schedule with little room for error.
