Jeff's engines are on the launch pad right now. The ULA Vulcan rocket uses two of them in the first stage. New Glenn will use 7 of them and be reusable (eventually).

Vulcan is a standard throw-away rocket intended to replace the Atlas that has flown for many years.

I'm still highly skeptical that an engine with that large of a chamber and that high of a chamber pressure can survive, but I guess we'll see!

They have test fired several of them. It is a hard problem and they have had their share of difficulties in development, but it looks like they have gotten it to work. Time will tell.
