How did war-focused economies change the way industry operated?

War-focused economies shifted industrial operations towards mass production of military goods, leading to increased government intervention and planning. Industries adapted by retooling their facilities to produce weapons, vehicles, and supplies, often at the expense of consumer goods. This transition also spurred innovations in manufacturing techniques, logistics, and labor utilization, as efficiency became paramount to meet wartime demands. Ultimately, the focus on war changed the nature of economic output and labor dynamics, often fostering collaboration between private industry and the government.
