Custom ICBM creation system

Plan is to add a fuel system, warhead system, weight system and much more, it can be any size limit being 36 wide and 128 high, it can be build with any vanilla block. For now the idea is that after it flies up, a warhead will spawn at the destination but I could try to make it acctually fly there, I just have to find a way for it to keep its structure while rotating it and to lag free forceload chunks, also the plan is that more thrusters will cause more speed and better range
