Blue Origin, the space company founded by Amazon.com Chief Executive Officer Jeff Bezos, has won a contract to supply engines for United Launch Alliance's massive Vulcan rocket, the companies said on Thursday. While Blue Origin has been seen as the front-runner for the contract for months, the win is a significant milestone for the Seattle-area aerospace company as it vies to become a player in the market for lucrative US military satellite launch contracts. Choosing Blue Origin's made-in-America BE-4 engine for the next-generation heavy-lift Vulcan launch vehicle is part of ULA's path to ending US reliance on Russia's RD-180 engine for national security missions. That engine currently provides the main power for ULA's legacy workhorse, Atlas V, which the Vulcan will eventually replace.
