War in Hearts of Iron 4 can be very complicated, as there are a lot of moving parts. You will have to keep an eye out for land troops, navy, and air force.

Automating one of these can help you handle all your battles better. This is why Guided Missiles are one of the best tools a HOI4 player can use, since it help you always control the air when it comes to strategic bombing.

These rockets will destroy everything in their way, with nothing coming even close to stopping them, as long as you have Air Supremacy.

To produce Guided Missiles in Hearts of Iron 4, players will need to build Rocket Sites in a region close to the one they want to bomb. The Rocket Sites will slowly produce 1 Guided Missile per day once you complete the “Guided Missile I” research.

How to Produce Guided Missiles in HOI4

As opposed to most other war equipment in HOI4, Guided Missiles aren’t produced in the Production tab using Military Factories. The only building that produces Guided Missiles in HOI4 is the Rocket Site.


To start producing Guided Missiles in HOI4, you will first need to do some research. Open the Research menu and look in the Engineering tab.

There, on the right part of the screen, you will see first the Experimental Rockets research and the Guided Missile I technology.

Unfortunately, Experimental Rockets is a 1943 technology, which means you won’t likely touch it for a while, and Guided Missile I is only efficient in 1944.

Luckily, most countries have bonuses for Guided Missile technology around the end of their focus trees, so make sure to look for them.

The Experimental Rockets research will allow you to start building Rocket Sites in your states.

Unfortunately, Rocket Sites isn’t a State Building, which you can build up to a set limit in every state, and it is a Shared Building, the same as Civilian and Military Factories.

This means that building Rocket Sites will take up space that you would normally use to build factories.

Considering their usefulness, if you complete all three Guided Missiles research slots, this is a risk worth taking.

Rocket Sites

Before even finishing the Guided Missiles I research, you can already start building Rocket Sites in your states to prepare for them.

Rocket Sites produce 1 Guided Missile per day, with a maximum of 100 Guided Missiles stockpiled per level.

You can only have a maximum level 2 Rocket Site in a province, so you will have a maximum of 200 Guided Missiles stockpiled in a state at the same time.

So, build a few Rocket Sites close to the enemy you want to bomb and wait for the Guided Missiles to be produced after you finish researching the Guided Missiles I technology. Until then, the Rocket Sites will be useless.

The whole purpose of Rocket Sites is to produce Guided Missiles in HOI4, and you won’t ever have to look in your Productions tab as you would for planes or tanks.

This is the advantage of using Guided Missiles to strategically bomb your enemies.

How to Use Guided Missiles

The moment you finish the Guided Missiles I research and have a few Rocket Sites in your provinces, you will start producing a lot of rockets to use against your enemies in HOI4.

To use Guided Missiles in HOI4, all you need to do is select them on the map (the small rocket icon) and right-click where you want to send them.

You can find them very easily if you open the Strategic Air map mode, as they are shown with a yellow rocket sign, as opposed to the normal plane icon.

Then, select the Strategic Bombing mission from the upper left corner of the screen (or just press “V” while the Guided Missiles are selected).

Once you have set them up to strategically destroy your enemies, the Guided Missiles will start flying from your base the moment they are produced, right into enemy territories.

Using Nukes

The initial Guided Missile will only have a small 500 km range, so you need to make sure that you have your Rocket Sites close enough to the territories you want to bomb.

If you build Rocket Sites on the eastern front and you have a war on the western front, you aren’t very likely to use them.

However, once you reach 1945, you can get Guided Missile III, which will give you an incredibly large range.

At this point, you can basically bomb almost any province on the map. This can be very useful when you also unlock Nukes since you can bomb someone’s capital without actually having to send any planes there.

If you want to stockpile more Guided Missiles to also get Air Supremacy, just stop the Strategic Bombing command and wait for the site to produce more.

They will help in getting Air Supremacy the same way normal planes do, but they slowly “die” since they explode each time one hits the ground.

Missing Equipment Production – Guided Missiles

The main reason most players will wonder how they are supposed to produce Guided Missiles is because they got this notification that they are missing equipment production for Guided Missiles in HOI4.

Even though you are producing tons of Guided Missiles, the game, for some reason, makes you think that you aren’t doing something right.

This notification is just a bug that appears when you set up a Rocket Site to Strategic Bomb an air region, and all of the Guided Missiles disappear because they have all been used up.

You don’t have to do anything to “fix” this problem since the Rocket Site produces the Guided Missiles without any help from you.

Players will never have to go into the Production tab to help in building their Guided Missiles, so this is just a bug from all points of view.

That’s everything you need to know about how to produce Guided Missiles in Hearts of Iron 4 (HOI4)!
