Steel Behemoth Nice basic recipe, clearly meant primarily for LEO or not far beyond that, and let me be clear: that's not bad, just a definitive characteristic. One negative on the second shuttle especially is that because you clip tanks into the spine of the load bay, the potential load in the build screen is compromised size wise. So a matter of load dimensions, and that's always been a factor for me. The nose is simple, unorthodox and with some imagination (key to this game) much can be made of it. Nice shuttle, I personally like the shuttle's engine setup but it is overkill. The booster should be doing part of lifting the shuttle, not only lifting itself. There is some unnecessary engine mass in your shuttle. you might as. Note that if the shuttle can't lift itself when loaded (max load to LEO), that's good. It may lift itself unloaded or not. It means that the booster is significant in the equation and will fall away once the loaded shuttle can continue to LEO, losing unneeded engine mass. But you are on a good shuttle design trajectory. Well done.
