seemingly forever so same business model for the ULA launch vehicles.
There also was the lack of market pressure to drive down launch costs so it was easy / status quo to just buy expensive engines from others.
So it's not like ULA can just ramp up their in-house engine department. They need to start a department from scratch, then develop designs, test / prove them out, produce working engines, and then ramp up engine production.
