"Digital computers" would've been a more accurate usage in the comment to which you're responding. World War II guided weapons (mainly just the German V missiles) used very simple and rudimentary analog computers for coursekeeping, and World War II gun laying and fire direction was done with analog integrating machines of impressive heft and complexity [1]. They're actually very fascinating devices, not to mention being among the pinnacles of the manual machinist's art even in that art's own halcyon days, but they're not really relevant here.
