Hi, welcome to this post, Everything you need to know about Hearts of Iron IV – Minelaying & Minesweeping Strategy may be found in this guide. Take each step in accordance with this guidance.

This manual will teach you how to operate your fleet effectively. To make using your navy as easy as feasible, ship templates are also offered.

Minelaying & Miningsweeping

A minefield that is fully satured will bring the enemy many penalties.

Although many players don’t bother with minelaying their effects are quite strong!

The best places to mine are:

• Chokepoints: where the enemy will pass most often.
• Protect your own coast from naval invasions

You can place mines on a Surface ship or submarine. While they are technically more cost-effective than submarines for placing mines in the surface, destroyers can also be used to place them. However, they are more vulnerable to being spotted from enemy ships. Submarines are the best choice for minelaying.

Planes can be used for minelaying/minesweeping as well, but this is unlocked extremely late-game, in 1942, and requires quite some research. This point will mark the end of the naval war. Despite being locked very late, mine-laying airplanes are actually quite useful.

1936 Mine-laying submarine

This design is the cheapest torpedo. All subs must have at most one torpedo. It also has minelaying tubes. A few of these will suffice to fully saturate certain sea zones with mines. Five subs for mine-laying should be enough.

Minesweeping

Only surface ships can do minesweeping. The Destroyer is most cost-effective for this task. Since AI and players rarely use mines, it is best to start building them only after the enemy has started laying mines.

1936 Minesweeping Destroyer

This is a simple minesweeper model; it’s much more cost-effective. Two of these are all you will need, and only if your enemy has actually laid mines.
