RL-10C is new. Delta III used the B and DC-X used something completely different.
Interesting. I was going by Wade's website which listed the D3 as using the RL-10C. Should let him know the error. -

RL-10A-5. Throttleable to 30%. -

I see that on the DC-X, but what about the Delta 3?RL-10C is new. Delta III used the B and DC-X used something completely different.
RL-10A-5. Throttleable to 30%. -

It happens I suppose. In any case, the RL-10C does seem to be a serious improvement over the RL-10B in terms of production cost. -

NASA’s delay moving forward with its next-generation Space Launch System (SLS) heavy rocket has caused consternation in Congress and concern in the aerospace industry. Pratt & Whitney Rocketdyne (PWR), makers of the space shuttle’s main engine, faces a significant gap in planning for the future and uncertainty in its workforce. No surprise the division of United Technologies Corp. may be up for sale, reported the Wall Street Journal .
“It’s a real challenge on a couple of fronts,” PWR Vice President John Vilja said in an interview with me last week. “We don’t have any way to spend our discretionary resources on whatever the government plans to do next... People are getting out of the industry and it’s causing a brain drain like we’ve never seen before.”
Uncertainty and the lack of a clear future means engineers who worked on the space shuttle’s engines are now looking at other employment options and bailing out of aerospace. The skills to develop and modify new rocket engines goes out the door with them. -

ughhh. Well, it seems to be working (gutting the SLS option).
Thanks for the link. -

America is it's own worst enemy, I'm sorry to say...
