Decided I wasn't getting quite enough TWR at launch and added another NK-15 in the center, made a few minor tweaks with avionics/RCS/batteries, and then I decided to make a heavy version for shits
Side boosters are identical to the center core except obviously have nosecones above the avionics ring so tooling costs will be minimal, and now this bad boy can lift up to 75 fucking tons to low orbit. It uses propellant crossfeed between the cores like was originally planned for the F9 Heavy instead of throttling down center core like the F9H ended up actually doing, mostly just because crossfeed in KSP is way fucking easier than getting mechjeb to do thrust management stuff that's super easy IRL.
Upper stage and fairings will probably be rebuilt and widened to the full 4.5m diameter by the time I actually have a need to lift 70t+ in my KSP game for hauling station parts and shit, and I also need to get some decent hydrolox engines or something to make a big dick dV upper stage for interplanetary missions since even with just a 1 ton payload this kerolox is maxing out at around 15km/s.
