Fair point.
> There were plenty of engines developed in the US in that timeframe.
Engines that actually flew or at least fully finished development. As far as I know there are none.
- orbital-decay 4y agoBA-810 (by a SpaceX predecessor, huge cheap engine!), Fastrac, RS-68, XRS-2200, TR-106, to name a few. These are only large liquid fuel engines created from scratch which either flew or have been fully tested in the US in a decade before the Merlin-1A. There were many more solids, derivatives, small engines, upper stage engines etc.
