The demands of total war accelerated technological development across the galaxy. Both sides invested heavily in new weapons systems, from the Republic's experimental stealth ships to the Separatists' massive droid foundries. The planet Geonosis, with its massive droid factories, became a crucial strategic asset, while worlds like Kamino gained unprecedented importance due to their cloning facilities.
The arms race extended beyond conventional weapons to biological and chemical agents, though these remained officially prohibited. The Dark Reaper project, a Separatist superweapon that could harvest the Force itself, represented the war's escalation toward weapons of mass destruction that could fundamentally alter the nature of conflict.
Medical technology advanced rapidly to deal with the war's casualties, but this progress came at enormous cost. Bacta production increased exponentially, while cybernetic replacement limbs became common for veterans. These medical advances would benefit galactic society long after the war but were developed through the crucible of massive human (and clone) suffering.
