I built this SSTO to carry cargo that doesn’t fit into a cargo bay. I call it my outboard ssto. My goals was for it to be not cheaty - no autostruts go through empty space such as where the cargo goes. The root is the cockpit, and the rear upper horizontal stabilizer is the part that is strutted together so the 2 bodies don’t flail. The raised design in the back allows for extra room.

MJ is only used in the screenshots, the craft file does not include it.

A stock aircraft called Outboard SSTO 100t (noMJ). Built with 161 of the finest parts, its root part is mk2Cockpit.Standard.

Built in the SPH in KSP version 1.3.0.

T, Z
SPACE to start
needs the whole runway with 100t cargo
ascend at about 15 deg
don’t need to go over 300 until 6000m+
back to 10 deg above it, to pick up speed, continue all the way at about this angle
you should have 1200+m/s at 20km when you start slowing and need to ignite closed cycle
2- switch to closed cycle
4- nukes
keep going, oxidizer should run out around 70k apoaps, continue with nukes and circularize (turn off normal engines with 1 to not confuse MechJeb about available thrust before you turn off the nukes)
