> Aerojet is the sub on this system. Surely they understand propulsion well and it is unfortunate that Boeing's name is taking the hit.
From what I can tell, Aerojet is hot garbage.
They tried to build a new engine for NASA during Constellation and their incompetence is one of the (many) reasons the program got cancelled.
They tried to build a new engine to compete with Blue Origin over the Vulcan 1st stage contract and lost. To a company which had never built an engine with a preburner before.
I know they've got a lot of heritage, but the only worthwhile engine they currently make (RL-10) is a variant of a decades old design. I'm entirely unsurprised that the service module they're responsible for isn't working well.
