Reply to comment by Adeldor in After Vulcan comes online, ULA plans to dramatically increase launch cadence by OutlandishnessOk2452

When i read their press thing i thought it sounded like something might be up. It went from LET.GO we got the engines to we got lots of and lot more testing to do

BO couldn’t send two PERFECT rocket engines? Like you know this is the most important thing as everyone as talked about ULA being beholden to BO. And delays and many other things.

So this is a huge red flag to me. The fact launchs go from 2 this a year a few more in 24 then every two weeks makes me think ULA is seeing that a year or two or more to get things right. Not a good sign

why ULA went with BO has never really made sense can anyone tell me why?

Eh, it took SpaceX several years to scale to that sort of launch cadence. I certainly wouldn't expect Old Space to miraculously reach a flight every other week within a year.

Aerojet's AR1 engine was way behind in development. In short, they didn't want to design it unless someone else was paying for it and that made development drag out. BO, on the other hand, was building the BE-4 on its own dime regardless of whether someone else was interested in buying them. Aerojet basically has no ambition as a company.

AR hadn't made an engine since the rs-68, and that's a gas generator.

That ULA chose to go with blue origin is either an indication of what they think of AR's technical ability, of how much AR wanted, or some mix of the two.
