Bloomberg reports that “Russia said it will no longer export rocket engines to the U.S. to launch military satellites, adding to a dispute in Washington that already pits the two biggest U.S. defense contractors against billionaire Elon Musk.”  

“Russian Deputy Prime Minister Dmitry Rogozin told reporters in Moscow today that Russian engines can be used only to launch civilian payloads, amid tensions over Russia’s support for separatists in Ukraine and the U.S. and European economic sanctions that have followed.”
