I didn’t think Amazon would get another batch up this year. Good on them. They must have been ready before the DOD missions and jumped up in line.
Mission success
Down to 10x Atlas V launches left. 6x Starliner and 4x Amazon.
6x Starliner
Will there even be 6 more Starliner flights before ISS retirement?
Maybe 4: 1 cargo, 3 crew?
The other 2 Atlases don’t have fairings. And they have 2-engine Centaurs. I have no idea if Boeing will try to re-sell those to recoup some losses, or if that’s even possible if they can’t get fairings.
