Mission «Strategic Bombing» in Hearts of Iron IV

A beginner guide: how to send bombers after enemy factories and buildings. Which buttons to click.

What this mission is

Strategic Bombing

How to find it:

In the air orders menu — the same place where you set «Air Superiority» or train air wings. Pick the mission, then right-click an enemy air region.

What happens next: Planes take off and bomb buildings in that region — Military Factories, Civilian Factories, Infrastructure, Synthetic Refineries, and other structures. They do not touch enemy troops on the ground.

How it differs from nearby missions:

  • Strategic Bombing — hits buildings (factories, roads, Anti-Air).
  • Logistics Strike — hits trains and trucks that haul supplies to the front.
  • Close Air Support — hits enemy divisions that are fighting right now.

Important: This mission does not change the air region colour on the map. Red means the enemy controls the sky. Your bombers get shot down before they reach the factories. Give fighters «Air Superiority» first.

Check range: Every plane has a combat radius. If the air base is too far, planes may not reach the targets. The UI shows what percent of the region is covered. 100% is good; less is worse.

A button in the air menu. Bombers hit buildings, not soldiers in battle.

It barely helps you win. Turn it on if you want bombing for history or for fun.

Why bother

First reason — weaken enemy production. A damaged Military Factory stops making tanks, planes, and guns. While it is repaired, the enemy gets less equipment. The effect is slow, but after a few weeks you may see fewer enemy divisions.

Second reason — lower War Support. Bombing cuts the enemy’s War Support. The cap from raids is about −30%. Bomb occupied land instead of core territory and the effect is half as strong.

Third reason — pull enemy fighters away. When your bombers start hurting buildings, the enemy often switches fighters to «Interception». Sometimes they pull planes off the front to defend the rear.

What blocks itHow it worksWhat to do
Red regionEnemy fighters shoot down your bombersGive fighters «Air Superiority» in this region
Anti-AirEach Anti-Air level cuts bomb damage by 12%Five levels in a region means −60% damage. Sometimes bomb Anti-Air first
NightBombing accuracy drops by 50%Bomb by day, or add a «Radio Navigation» module to the bomber design
Heavy rainAccuracy −50%, mission efficiency −30%Wait for clear weather
Low fuelMission efficiency ×0.25Watch your national fuel stockpile

Why you have lots of bombers but factories stay intact:

  • Red region. Check the air colour. If it is red, enemy fighters shoot your planes down. Set «Air Superiority» first.
  • Heavy Anti-Air. Five flak levels in a region and your bombs barely scratch anything. Sometimes bomb Anti-Air first.
  • Night or bad weather. In the dark or in rain, bombs miss. Day and clear skies work better.

On paper it weakens enemy factories. In practice the effect is slow and small.

For winning, build fighters on «Air Superiority». Bombers are for a “air war” playthrough.

Do you actually need it

Honestly, almost not. Beating the AI is easy enough, and bombers will not swing much. In multiplayer, factories are better spent on fighters for «Air Superiority». The usual reason to use it is a historical run or plain fun. As Germany, if you want France through the Maginot Line, bombers can help crack bunkers.

When to use it

  • The enemy has factories your bombers can reach.
  • You will not capture that land soon — you are not breaking your own future factories.
  • You want a historical or roleplay game — bombing for the vibe.

When not to use it

  • The region has no factories or other important buildings.
  • You will march in soon and want those factories intact.
  • You need a win, not a show — fighters and the army on the ground are better.
  • Fuel is tight — bombers burn a lot.

Small countries: do not send bombers over empty regions. Every sortie costs fuel. If you turn the mission on, pick targets that matter.

Almost never needed. Tanks and regular air are enough against the AI. In multiplayer, spend factories on fighters.

Good for roleplay: a historical campaign, cracking bunkers, or just watching factories burn.

What to bomb first

How to pick targets: When you assign the mission, open «Strategic bombing priorities». Buttons there set which building types matter most. Leave everything default and damage spreads evenly across all types.

TargetWhy bomb itWhen to skip
Military FactoryEnemy stops making equipment. Main targetIf you will capture that land soon
Civilian FactoryEnemy builds and repairs slowerIf you will capture that land soon
Anti-AirRemoves protection. Bombs hit harder without itIf Anti-Air is already gone
Air Base50% chance to damage parked planesIf range does not reach the base
Synthetic RefineryEnemy loses fuel and synthetic rubberIf they already have plenty of oil on the map
Infrastructure, railways, supply hubsEnemy moves and supplies slowerIf you advance soon — you will repair it yourself

Beginner tip:

  • Max out Military Factory first.
  • Then Civilian Factory if you want to hit construction.
  • Strong Anti-Air in the region? Prioritize Anti-Air, then factories.

Do not:

  • Leave every priority the same — damage spreads and gets weaker.
  • Bomb Infrastructure where you will attack soon.
  • Use this mission on trains — that is «Logistics Strike».

If you turned it on anyway: in «Strategic bombing priorities» — Military Factories first, then Civilian Factories, then supply (railways, supply hubs, Infrastructure).

For a normal win you do not need to tune targets — capturing factories on the ground is simpler.

Which planes get this mission

Strategic Bomber Tactical Bomber

Strategic Bomber — built for this. Long range and a heavy bomb load. If you have them, use them here.

Tactical Bomber can do it too, but worse — less range and fewer bombs. It can switch to «Close Air Support» when ground troops need help.

Give this mission

  • Strategic Bombers — this is their job.
  • Tactical Bombers — if you have no strategic ones or range is too short.

Do not give it

  • Fighters — they take «Air Superiority».
  • Close Air Support planes — they support troops on the ground.
  • Naval Bombers — they attack ships.

Three common beginner mistakes:

  • Mistake 1: Bombers without fighters. Region is red — planes die. Fighters first.
  • Mistake 2: Bombing Infrastructure where you will attack soon. You break your own roads.
  • Mistake 3: Keeping Tactical Bombers on this mission while the front is hot. They cannot help infantry and bomb factories at the same time.

Strategic Bomber — if you built them “for looks.”

Do not give this button to fighters — they want «Air Superiority».

Bottom line

1. What it is: A bomber mission that wrecks enemy buildings.

2. When to use it: Almost never for winning. Yes for fun or a historical scenario. No if there is nothing to bomb or you capture the land soon.

3. What matters: Fighters on «Air Superiority» first. Red region on the map — bombers never arrive. Check range and fuel.

4. What to bomb: In priorities, max Military Factories. Bomb Anti-Air if it blocks you. Skip Infrastructure if you advance soon.

5. Who gets it: Strategic Bombers. Tactical if you must. Not fighters.

Almost useless for winning. Build fighters, take factories on the ground.

Turn it on if you want bombing just for fun.
