Half the satellites is still a lot of satellites. BO would need to ramp up to at least monthly launches sometime in the next two years. SpaceX is only doing a little better than that, and they started sending the Falcon 9 to orbit in 2010.

New Glenn is a lot bigger than Falcon, though. It has twice the capacity to LEO by weight and more than twice by volume. So if a Kuiper satellite is the same size as a Starlink one, they should be able to launch 120 per flight. 14 flights to get above 1618. That could be done within a single year, although that's a big ask for a company that hasn't hit orbit yet...

New Glenn is a paper rocket built around unproven engines.

Starlink satellites don't use Falcon Heavy.
