DFRC's Horizontal Launch Study
NASA Solicitation: Horizontal Launch Study
“The Horizontal Launch Study (HLS) study will provide an assessment of horizontal launch architectures for several payload classes to access/service LEO for both military and civilian applications. HLS will open the trade space to several payload classes from micro to medium sized payloads and different staging scenarios from subsonic to supersonic separations speeds for each payload classes. HLS will identify architectures that support near term LEO mission capabilities along with identifying mid-term technology investment areas that will enable larger payloads and future capabilities.”
