The RD-101 was developed simultaneously with the RD-100 but with no German involvement (for security). It was more compact, had increased thrust (37,000 kgf), increased pressure and an increased alcohol concentration. They were nicknamed drunk engines and test specialists used to get the alcohol out afterwards for their own uses!
