The VT fuze (proximity fuze) that the U.S. military pushed hard during World War II should also have been mounted on 40 mm Bofors autocannons and wreaked havoc, but it has changed to “they couldn’t mass-produce transistors, and during the war VT fuzes were used on 127 mm (5-inch) guns.” Also, meanwhile, the German V1 missile and V2 missile have had their ranges drastically shortened, the former should have had a range of 1500 km and the latter of 800 km or something like that, but their ranges have been greatly shortened, and moreover, the various German air-defense missiles that raged in the late war as well as the anti-tank missiles have changed to “they couldn’t be mass-produced and didn’t make it into actual combat in time.”
