Re: Rocket Monopoly - United Launch Alliance

While the military seems to have pulled the plug on the Russian engines with Nasa doing the oposite. NASA certifies Russia's RD-180 rocket engines for manned flights Now this could be because the Atlas V is to be used for the Dreamchaser and for maybe the x37 space plane also.

Re: Rocket Monopoly - United Launch Alliance

Counting down our dependance on Three additional Russian RD-180 rocket engines being prepared for shipment to US

US lawmakers have recently sought to curb the purchase of RD-180 engines as part of Washington's package of economic sanctions against Moscow, passing a law obliging Washington to develop its own next-generation rocket propulsion system.

RD-180 engines for use with Atlas-5 launch vehicles has been a very dependable engine

Since 1999, Lockheed Martin Atlas III and Atlas V launch vehicles have made at least 86 flights using the RD-180. According to Energomash figures, the US has now received 116 such engines.

In addition to the RD-180, the Russian rocket engine maker also produces the RD-181 for the Antares, an expendable launch system developed by Northrop Grumman subsidiary Orbital Sciences Corporation. The RD-181 is a modified version of the RD-191, derived from the RD-180.
