With the advent of Factorio 2.1, comes the abilty to mod in rockets with different cargo capacities as seen in FFF #441.

This mod adds a new high-capacity rocket silo that produces larger cargo rockets, which have a larger (customisable) capacity, but also require more rocket parts to built. They scale with quality like regular silos.

The larger cargo rockets use the old more substantial sprite from factorio 1.x.
