"Further refinements to the chemical formula and process for making high explosives."

This upgrade doubles the damage for explosives. That is, Rockets, Mines, Cluster Mines, and Blast Mine are affected. It makes those weapons a lot more useful towards the later levels, by keeping up with the high HP of the advanced Titan.

It should be noted that the the collateral damage to your own buildings is not doubled from these sources.

After this research benefit from each Reactor near Rockets is doubled.
