“They’re coming off the line at one a month right now, and then we’re ramping from there,” he said of the second stages, known internally as GS-2. “It would be ambitious to get to the upper level, but we want to be hardware rich. So, you know, we want to try to keep building as fast as we can, and then with practice I think our launch cadence can go up.”
The biggest part of increasing cadence is manufacturing. That means BE-4 rocket engines for the first stage, BE-3U engines for the upper stage, and the stages themselves.
“With rockets, it’s hard,” Limp said. “Building prototypes is easy but building a machine to make the machines in volume at rate is much harder. And so I do feel like, when I look at the factories, our engine factory in Huntsville, the rocket factory here at Rocket Park and Lunar Plant 1, I feel like when you walk the floor there’s a lot of energy.”
Since he joined Blue Origin about two years ago, Limp said increasing production has been among his foremost goals.
“You’re never done with manufacturing, but I feel on the engine front we’re incredibly strong,” he said. “We’re going to double the rate again next year. We’ve got work to do, but on second stages I feel like we’re getting there. With the booster, we’re getting there. The key is to be hardware rich, so even if some of these missions have anomalies, we can recover quickly.”
Next stop, the Moon
Blue Origin recovered the New Glenn first stage from last week’s flight and brought it into port on Monday. Although it looks much cleaner than a used Falcon 9 first stage, much of this is due to the use of methane propellant, which does not produce the soot that kerosene propellant does. It will take some time to determine if and when this recovered first stage will be able fly again, but if it’s not ready soon Blue Origin has a third first stage nearing completion.
