Plus, it gave us an exposure to oxygen-rich closed cycle engines, which the Soviets/Russians perfected, but the US hadn’t. Now, the Vulcan will fly on an American engine using this technology.

@torybruno why hasn’t anyone seriously considered the use of the F1-B engine? -

And the RD-180 is one of the best rocket engine designs. It’s a very powerful and reliable engine. When Russia was less of an adversary that deal made fantastic sense. It’s only the geopolitics that have changed.
