An All-in-one Rocket production factory. It takes Coal, Sulferic acid, Calcite and Lava as inputs and saturates the standard speed Rocket part production. You also need to jump start the Coal Liquifaction with heavy oil, as always.
The first bottleneck is coal. 1 saturated Turbo belt (60/s) of Coal is enough for 5 Rocket Silos. The stone output should be relieved similarly.
