摘要

The U.S. Air Force has quietly unveiled its initial steps toward replacing the Russian-built rocket engine used today for U.S. national security launches, an effort driven by mounting congressional pressure but slowed by the fact that the Pentagon's current launch service provider is independently pursuing its own strategy. Air Force procurement announcements released late April 24 offer a first glimpse what Gen. John Hyten, commander of Air Force Space Command, acknowledged is a "complicated" and "difficult" strategy that may produce an American-made rocket engine by 2019, as Congress has directed. But speaking with reporters at a breakfast here April 28, Hyten said it likely would take another two years to integrate the newly built engine into a rocket.
