Welcome to the LR1 Skyhammer (Launch vehicle, Reusable) prototype!
The LR1 is a stage-and-a-half spaceplane based on the Lockheed company'sLS-200 design, which was one of the Space Shuttle alternative concepts.The configuration has been updated to include the 40 years of technologydevelopment since the design of the LS-200: modern electronics and systems,a CH4/O2 propulsion system, and computer aided structural and aerothermaldesign.
PROTOTYPE: p1
This release is a prototype. It contains only the essential features necessary for liftoff, ascent, and orbital insertion. In particular, there are:
 - No RCS thrusters. - No restartable engines. - No orbital maneuvering engines. - No aerodynamic control surfaces. - No landing gear. - No payload bay doors.
My intention is to develop each area of the LR1 to a reasonably usable level, then move on to the next (with fixes and improvements all around as the releases roll). Hopefully this will let me get feedback on various aspects of the addon as they become available.
