All RD180s have been received and are in Decatur. They will fly out with Atlas over the next several years
I wonder if Amazon could be persuaded to move some of their later Atlas missions to Vulcan, in exchange for a slight discount or more satellites on each launch. That could free up a few Atlases if there was a more pressing mission with less launcher flexibility, such as Starliner.
The two critical dates for Kuiper is July 30th, 2026 and July 30th, 2029, IIRC.By those dates they need 50% (~1618 satellites) and 100% (3236 satellites, I think) of their fleet up to secure their ITU rights.We need to make two assumptions:A) An EELV-class LV can carry 50 satellites.B) Their first operational launch will be around Q1 2022. They might launch some prototypes earlier.This means that they will need about 35 launches between Q1 2022 and Q2 2026. Which is about 10 launches per year.
How many RD-180s are left in the ULA inventory for the Atlas V, especially in light of US sanctions against NPO Energomash?

ULA doesn't need and won't be buying any more RD-180's.
