US to lack full space launch capability beyond 2019 without Russian engine

America continues to suicide itself out of existence any way it can, with space also being a frontier:

 

In January, the US Air Force awarded contracts to Orbital ATK and SpaceX to develop prototypes of US-built rocket engines to replace the RD-180.

 

Full US space launch capability may be delayed beyond 2019 if it cuts its supply of Russian-made RD-180 rocket engines, US Air Force Secretary Deborah Lee James told the Senate Armed Services Committee on Wednesday.
