You mix up everything, and many posters do that further down.
These are the relevant rockets and their first stage engines that fly from US soil:
1) ULA Delta IV: US made RS-68 (new).
2) ULA Atlas V: Russian made RD-180 (new).
3) SpaceX Falcon 9: US made Merlin-1 (new).
4) Orbital Sciences Antares: Soviet made NK-33 (decades old, now refurbished in USA).
