The Russians responded fast
Just yesterday, a friend who read the article "Cold War 2.0: Dangerous games from Washington's 'hawks'" pointed that "Country that still rely on Russian engines to deliver communication satellites into orbit know pretty well whom they are dealing with."
Unfortunately, Washington's "hawks" proceed in fast moves that show a willing to take the risk of the unthinkable:
“US lawmakers in the House of Representatives have approved $220 million in funding to help the Pentagon replace the Russian rocket engines used in its satellite launches.”
“The measure, which faces opposition from the Obama administration, calls on the US military to use an American-built engine for launching military satellites into orbit. The US relies on Russian-made RD-180 and NK-33 engines to launch military and civilian satellites into space.”
“SpaceX argued that ULA [a joint-venture between US aerospace giants Lockheed Martin and Boeing] has been buying RD-180 engines from NPO Energomash, Russia's leading developer and manufacturer of liquid propellant, which it said is subject to the control of Russia’s Deputy Prime Minister Dmitry Rogozin.”
“After hearing testimonies from US State, Treasury, and Commerce departments, US Court of Federal Claims Judge Susan Braden ruled the purchases did not violate US sanctions against Russia and lifted a temporary ban that prevented US firms from buying the Russian rocket engines.”
“However, following the ruling, Rogozin said Russia would stop supplying the rocket engines to the US, retaliating against Washington’s sanctions on Moscow over the Ukraine crisis.”
"'We are very concerned about continuing to develop high-tech projects with such an unreliable partner as the United States, which politicizes everything,' Rogozin said."
"In an email statement, US Rep. Rodney Frelinghuysen (R-New Jersey) said Washington 'must not be wholly dependent on Russia to” launch military satellites into orbit and should focus on the “development of a next generation rocket engine.'"
