The Atlas V, powered by a NPO Energomash RD-180 engine manufactured by Pratt & Whitney. We have come a long way since a R-7 powered by RD-107 engines became Russia's first ICBM in competition with the first US ICBM the Atlas powered by Rocketdyne LR-43s. Pratt & Whitney eventually bought out Rocketdyne. How curious that a descendent of the engine that put Yuri Gagarin in orbit ended up powering a descendent of the missile which orbited John Glen.
