Hits national unity making the target nation more likely to surrender (amount depends on victory point worth and infrastructure level, so you cant just nuke some island they don't care about). This is really their primary use: to force surrender on a stubborn enemy.

Damages building. Everything from forts to naval bases to factories.

Damages any units in the province, including airplanes stationed in bases.

Today's topic is an explosive one (heh) - nukes!Nuclear weapons are a late game tech and there are several steps to acquire one. First up is researching Atomic Research (1940), Reactors (1943), and finally Nuclear Weapons (1945). To actually produce nuclear bombs you need to construct Reactors which will slowly churn out the weapons. The more reactors the faster you can produce nukes (note that reactors compete for space with industry in states). Many majors have national focuses that let them focus on the nuclear research program and speed things up.To launch a nuke you need to have strategic bombers in range of the target and air superiority.This is early days yet, so nukes, while incredibly powerful are not the massive world destroyers of the cold war. However they can still do serious damage, and other effects:Oh btw, in case someone missed the announcement HOI4 now has a release date set for 6th of June!Next week we will be off for Easter, but the week after we taking a look at the Generic Focus tree that all non-majors use. If you get the HOI craving next week there is still the World War Wednesday stream where I believe Daniel and Jake have started to take on China as Japan.
