I don't know if "lots" is the right word, but ULA pretty much depends on buying RD-180's. If it wasn't for Congress lifting the restrictions they'd be out of the game. If you ask me, if you are a rocket company and don't make your own engines you are not a rocket company. External forces can instantly turn you into an expensive fuel and liquid oxygen tank manufacturing company that can't launch a paperclip into orbit. The smartest thing SpaceX has done, perhaps by accident or genius, was to design and manufacture their own engines. Well, their own everything in their case. ULA charges USD $400 million for a launch and SpaceX under $200 million (I think it's $160). One is a perfect example of what happens when private enterprise and capitalism go to work and the other is representative of anything government touches, funds or insists on keeping alive despite reality. The same mechanism that gives you billion dollar websites and a myriad of programs that do nothing but burn money a N times what a more effective private effort could accomplish. You can launch three SpaceX rockets for the price of one ULA. And now that they are landing them and will start to re-use them the equation might approach a ridiculous case of perhaps 10 launches for every 1 from ULA.

What Russia does doesn't matter any more. Nobody is going to be able to compete with what Musk and his team have created. I am not sure most realize how much of a game-changer this will be.
