Hmmn. Russian engines under a US “nameplate”, eh?

Thanks for the update.

The Russians couldn’t sell the rockets without a Western partner. They started working with Aerojet about 15 years ago to get them in usable condition by our standards, and have Aerojet do the testing to prove it. They were workable engines, though the condition of them was initially pretty shocking by our standards.

Since Titan is history, it’s worked out well for Aerojet. PWR is still selling RJ-10s, though having to do two types of it (one for Delta IV, another for Atlas V), which drives up their costs.
