United Launch Associates (ULA), the rocket enterprise from Boeing and Lockheed, has ramped up its commitment to Jeff Bezos' Blue Origin rocket engines. The two companies agreed to expand production capability of Origin's BE-4 rocket motor, "an important step toward building (them) at the production rate needed for the Vulcan launch vehicle," said Bezos. Last year, the two companies formed a pact to develop an engine that that can replace the Russian-built RD-180 engines originally planned for Vulcan -- ULA's successor to the Atlas V. Due to a US congressional ban on Russian products, ULA can no longer purchase RD-180s.
