I spent a while developing a fully reusable rocket assisted spaceplane for my career save to do tourism and various LKO tasks, it can get whatever you can fit (or clip) into the cargo bay to orbit and it must glide pretty well on the return cause even I can fly it pretty easily. The two boosters have chutes and drop off quickly leaving the rest to climb to orbit, which it can do with a full payload with about 500ish m/s to spare. Called it the 'URAL-LV' cause the acronym is Unmanned Rocket Assisted Aeroplane Launch Vehicle.
Took a bunch of tries to balance it but it works great now (bar some totally unforeseeable electricity depletion leading to running out on final approach to the KSC).
