Indeed, one chart is titled <i>\"International Partners Have Lots of Capacity\"<\/i>. The rest of this presentation contains procurement-sensitive information and will not be published here.  <\/p><p>That said, it is obvious that even a year ago pragmatic thought was given to how a variety of launchers could be used for human, cargo, and other launch purposes including ways that mission profiles (DRM 4) usually associated with a HLV could be accomplished in whole or in part by the use of expendable launch vehicles.
